for the 1100th time what oil do you use?

[Firebirdjones]

No studies that directly relate to that that I'm aware of, but you can send your used oil in for testing and it will tell you exactly how your engine is wearing and whether the oil you use is working for you. The kit is free and I think the cost of the test is $25. Money well spent if you care about your engine.

Here is a cheat sheet to tell you whats going on inside when you get your test back.....

Aluminum : Pistons, bearings, cases (heads & blocks).
Chromium: Rings, a trace element in steel.
Iron : Cylinders, rotating shafts, the valve train, and any steel part sharing the oil.
Copper: Brass or bronze parts, copper bushings, bearings, oil coolers, also an additive in some gasoline engine oils.
Lead: Bearings.
Tin: Bearings, bronze parts, piston coatings.
Molybdenum : Anti-wear additive, coating on some new rings
(washes off as break-in occurs).
Nickel: Trace element in steel.
Manganese : Trace element, additive in gasoline.
Silver: Trace element.
Titanium: Trace element.
Potassium : Antifreeze inhibitor, additive in some oil types.
Boron: Detergent/dispersant additive, antifreeze inhibitors.
Silicon : Airborne dirt, sealers, gaskets, antifreeze inhibitors.
Sodium: Antifreeze inhibitors, additive in some gasoline engine oils.
Calcium : Detergent/dispersant additive.
Magnesium: Detergent/dispersant additive.
Phosphorus: Anti-wear additive.
Zinc: Anti-wear additive.
Barium : Detergent/dispersant additive

[Firebirdjones]

Here is a list of the different additives and how they work. Every oil is different and this stuff changes frequently....

Here is a comprehensive list (best you'll find outside of the lab) of multifunctional additives and their functions. Notice the same chemicals and compounds perform more than one function.


Multifunctional Additives (in Alphabetical Order) listed as to Functional Agent, additive category, general or specific chemical compound, and how it works, respectively.

Antifoamants or foam inhibitors (Protective Additive): polymers such as silicone polymers and organic copolymers of the silaxane's; creates a lens that reduces the bubble's surface tension.

Antioxidants or oxidation inhibitors (Protective Additive): ZDDP, ZTDC, Moly TDC, Antimony TDC, aromatic amines such as organic tolutriazoles, thiadiazoles, diphenylamines, olefin sulfides, carboxylic acids; decomposes peroxides and terminates free radical reactions. Increases temperature of base oil at which base oil may tend to oxidize. Oxidation of oil promotes polymerization of sludge particles and increases viscosity.

Anti-Wear and Extreme Pressure Additives (Surface Protective Additive):
ZDDP, ZTDC, Moly TDC, Antimony TDC, Organic Sulfur-Phosphorus-Nitrogen compounds, Borates and Borate Esters, Tricresyl Phosphates, amine phostphates, and other phosphate esters, Chlorine compounds, and lead diamylcarbamates, lead and barium naphthenates, sulfurized olefins; protective film interacts at various temperatures and pressures to provide either a plastic interface or to provide a compound which shears at the surface.

Demulsifier (Performance Additive): hydroxyalkyl carboxylic esters, alkenlycarboxylic esters; keeps water separated from lubricant.

Detergents (Surface Protective Additive): metallo-organic compounds of sodium, calcium, magnesium, boron phenolates, phosphates and sulfonates such as alkylbenzene sulfonic acids, alkylphenol sulfides, alkylsalacyclic acids; Lift deposits from surfaces to keep them suspended.

Dispersants (Surface Protective Additive): Alkylsuccinimides, alkylsuccinic esters (alkenyl succinimides); chemical reaction with sludge and varnish precursors to keep them acid neutralized and to keep them soluble. Detergent-dispersants often are the same chemical or come in compounds to accomplish the combined function(s).

Emulsifiers (Protective Additive): Polyisobutylenesuccinimides, alkenylsuccinate ester/salts. polyester amides, alkyl aminoesters; promotes a stable emulsion or mixture of oil and water.

Friction Modifiers or Friction Reducers (Performance Additive): Organic fatty acids and amides, lard oil, high molecular weight organic phosphorus and phosphoric acid esters such as Tricresyl Phosphates, ZDDP, ZTDC, Moly TDC, Antimony TDC, family of diphenylamines and amides, and olefin sulfides. Reduces coefficient of friction formulated lubricant in the boundary lubrication regime. Some VII's also provide friction reduction.

Metal Deactivator (Protective Additive): ZDDP, ZTDC, Moly TDC, Antimony TDC, family of diphenylamines and amides, and olefin sulfides, heterocyclic sulfur-nitrogen compounds; inhibits corrosive effects of oxygen with metals and decreases metal interaction with oxygen compounds to reduce oxidation of oil.

Oxidation Inhibitors (See Antioxidants).

Rust Inhibitor (Surface Protective Additive): Barium sulfonates, amine phosphates, phosphordithioates, sodium thizoles (for coolants),

Pour Point Depressant (Performance Additive): polymethacrylates (PMA's); reducing wax crystal formation and increases solvency of oil at low temperatures. May be part of VII package.

Seal Swell (Performance Additive): nitriles, specific esters, organic phosphates and aromatic hydrocarbons. Increases volume of elastomeric seals.

Surfactants or Surface Active Agents (Protective Additive): family of diphenylamines and amides; usually part of the antioxidant package. Also provides enhanced friction reduction and allows oils to "climb" or spread on and over surfaces. Decreases but does not destroy surface tension

Soot Control or Soot Inhibitor (Protective Additive for diesels): Organic Barium compounds; keeps soot in suspension. Usually part of the dispersant package in diesel formulations.

Tackifiers (Performance Enhancement): copolymers of ethylene and propylene; helps oil cling to surfaces. Very useful in geared machines such as transmissions, differentials, and chains.

Viscosity Index Improver or Viscosity Modifier (Performance Additive): Olefin copolymers (OCP's), hydrogentated styrene-diene copolymers, styrene esters, polymetharylates (PMA's), mixed alkyl methacrylate-vinyl-pyrrolidines, aminated ethylene propylene, mixed alkylmethacrylate ethylene/propylenes; reduces viscosity change with temperature. Increases viscosity of base oil as temperature rises when base oil tends to thin. Some VII's may also act as dispersants by incorporating dispersant compounds.

So as you can see there are multiple "friction modifying" agents in todays oils...like Rotella has no Moly but tons of Phospherus....Red Line oils have tons of Moly...both excellent wear prevention agents....you want the "whole" package.....rust inhibiters....
performance enahncers ( also classified often as friction modifiers)...etc.
The Virgin Oil Analysis done often are of "older" oils.....example would be Chevron Delo....last year no Moly...this years batch got gobs of Moly....I go to the manufacturers product spec sheets and watch.....also send in various oils for VOA's which often times are done for free to keep the labs database up too date....
Yes the oil companies dont give out there receipe for sure...so knuckleheads such as myself and many others send in "new" oil to see what is in it with the spectrum analyzer......some sad ass **** aint it Like Mobil 5000...loaded with salt...yes salt....
So the bottom line is this....you want..
1. Friction Modifiers
2. Cleaning Agents
3. Rust Inhibiters
4. Viscosity Enhancers to maintain viscosity and not "wear" out of grade...
Many oils have a couple of the main drivers covered but lack in other areas....so often times we will add say a Valvoline Oil Treatment to enhance the friction modifiers and cleaning agents of say a Pennzoil 10-40 dino.....or Castrol GTX....and voila...you get RedLine $6 buck a quart type of performance out of $10 bucks worth of Pennzoil....funny how this works aint it

This might help you as to why you see Mobile stickers on the new GM cars. It's a marketing game.....it doesn't necessarily mean it good oil

The new GM dexos1 is more than just a standard, it's both a standard and a special license. While the auto manufactures have had their own motor oil standards, e.g., GM 4718M, Ford WSS-M2C929-A, and Chrysler MS-6395N to name a few, the new GM dexos1 standard takes it a step further by creating a special license, licensing fees, licensing logo, etc.

So in order for an oil manufacture to get on the official GM dexos1 approval list, receive the official licensing, and dexos1 logo, they have to pay General Motors a licensing fee and royalty fees based on gallons sold.

Mobil and Shell are a couple of majors who have embraced GMs official dexos1 licensing probably due in part to keep their vendor status.

Castrol, ConocoPhillips, Valvoline, and Amsoil are a few of the brands who have said NO to GMs dexos1 licensing, but manufacturer products that meet or exceed the dexos1 standards.

dexos1 is interesting because oils meeting the dexos1 standard are Group III Full Synthetic and ALL 2011 GM vehicles come factory fill with dexos1 and are required to use dexos1 motor oil at each oil change. So ALL new GM vehicles are supposed to run full synthetic motor oil now (no more conventional oil).

dexos1 is good because the specification boosts the oil performance in Volatility, Engine Sludge Protection, Piston Cleanliness, and Turbocharger Protection beyond that of regular API (SN) and ILSAC (GF-5) standards.

dexos1 is bad because gray area fine print have some consumers believing that they must buy officially licensed dexos1 motor oil in order to meet the requirements of their new vehicle warranty, which is simply not the case.

Last time I checked,,,Royal Purple didn't make the SM cut so they are not API SM certified.

I'll have to find the most recent oil study....it's a good read too.

I realize that nothing in this industry stays constant for long. I worked on industrial machinery for many years. One particular brand of large compressors used synthetic oil made by Royal purple ( but it was clear). I used literally thousands of gallons of the stuff. Customers would cheap out, and use different brand high end oils once in a while. Most of those customers would call me shortly there after. I would replace thier air ends, and misc parts, and fill it with RP. No more issues. I researched Royal purple, and ( at that time) found thier product to be superior to most everything else.

I have 3 trucks, 2 of which get used very hard. The drivetrains are all lubed with RP, and have never had an issue. Until recently, I used Castrol GTX in my engines. The ZDDP thing scared me, so I switched.

[butch86]

some sad ass **** aint it Like Mobil 5000...loaded with salt...yes salt....


this explains why mobil 5000 has dropped in price to less than bottom shelf prices. ie the walmart brand here in central mississippi is 14.98 for a gallon. mobil 5000 5w20 sells regularly for 13.00 for 5 quarts. this is at walmart. i also notice in stores i frequant what stock is sold pritty good and what sits for a while. the mobil synthetic moves great but the mobil 5000 stays put. i just wonder if this is because people know 5000 sucks or they are turned off by the 13 bux for 5 quarts.

great info FBJ its funny you know these things but when you read it its like wow oil ain oil is it? i love all the info in this thread.

I'm thinking it's because more and more people are paying attention and educating themselves on the games these oil brands are playing. Several years ago when it was mentioned that ZDDP levels are dropping and wiping cam lobes I think that started to really get peoples attention I know it did that to me.

Edit: I still need to sit down and find the recent oil comparison charts. I remember Valvoline full synthetic, Pennzoil Platnum synthetic, and one other being at the top while Mobile synthetic fell slightly.
Dino oils were Castrol GTX, Pennzoil (and I'm drawing a blank here) but I'll let the numbers speak for themselves.

Your top shelf oils are still Amsoil and Shaeffer.

[asphaltburner]

As long as it doesn't leak, I like to use Mobil 1 5W-30 in my modern vehicles.
As for the older vehicles, and those that leak some, I find NAPA (Ashland/Valvoline) 10W-30 is the best choice for protection and cost.
I use Castrol GTX in my '76 Camaro (10W-30) and '72 SuperBeetle (20W-50 due to it's specially added hydraulic lifters) to reduce heat breakdown.
For God's sake, the stuff has to be changed every 3000 to 8000 miles, so ya gotta buy what works best without costing more than a rebuild over the life of the engine.
Todd.

[Firebirdjones]

I think your choices in oils are fine. Nothing wrong with using dino oils to save money nowadays. The base stocks and additive packages are good enough in the quality dino oils that it's hard to justify the cost of a good synthetic. At this point when it gets down to it, synthetics advantage is really just longer oil change intervals. So if you don't mind regular oil changes the dino oil does a fine job.

[misternash2]

i've done an ls swap and i use castrol syntec 5-30 and a wix filter. i change every 10,ooo. i'm interested in doing oil analysis to see where i need to be changing it at. where do you guys go to for lab analysis?

i'm a refrigeration technician and we use sub-micron filters on our compressors and we have yet to have a negative lab result sent back. i looked into it, and the technology is there to run one on a vehicle, but for some reason no one runs one. i know of one guy only. he is a service tech for a major compressor company and travels all over the midwest racking up thousands of miles per year. anyone but me ever heard of this?

[Firebirdjones]

I use www.blackstone-labs.com

[butch86]

FBJ who do yousend your oil samples to? i have some kits on the way from Blackstone Labs but have been looking for a local company i may could use. will make some calls to some local companys that have fleet samples drawn and see who they use.

[butch86]

ha ha you answered as i was typing. thanks

[gchemist]

Castrol 10-30, it saved my old 305 twice from after loosing the coolant system. It's scary to see a digital meter go up to 285 going down the road trying to get to a station. Both times, I fixed the coolant system (heater core once and busted hose). Got it home, changed the oil, then drove it like I stole it!! A timing chain failure finally finished off the 305. I recommend and use Castrol.

[Hubscrub]

pennsoil 10-30 in everything since i was 16 now 30 still driveing them without issue recently switched to purolator filters

[Robert1970C20rstbukt]

I've always used Valvoline oil and AC Delco filters in my trucks, but I switched to Wix when the PF35 was no longer available locally.

[thirdstreettito]

NAPA (Pennzoil) 10W30 and NAPA Gold filter in the 88.

Rotella 10W40 and NAPA Gold filter in the 83.

Gonna try the new NEXTGEN oil in the 88.

i have used rotella t 15w 40 for years and years. the problem is the formulation has changed so much in the last few years its no better than bottom shelf oil ( store branded from the lowest bidder) i have been thinking of using moble 1 20w50 or amsoil high zink 20w50. i use zddp additive in everything flat tapped i own. the amsoil is very expencive about $11.50 a quart this would run 90 bux every oil change with the wix shorty racing filter i use on all my motors. i use melling select oil pumps and the cheap filters have been known to colaps with this pump.

most mechanics i know prefer moble 1 to most other oils. i am just looking for opinions on weight and brand yall like.

ps halvoiline and penzoil are a no go with me never will again. i would trust walmarts store brand first.

Lol okay, first thing, shorty filter? Why? Headers contact?
Wix? YES! Best filter, we only use them on our pavers.

Zinc this and that... No. Breakin oil yes, average use, no. Just no. Lol wen that block was made synth didnt exist, and its ran for how many years?? Hint hint.

Ur milling pump; yes! Best upgrade ever, have 22years on mine. Fun fact; napas hi vol pumps are made by milling just no name on the castings and 50 bucks less lol.

Ok now; oil facts; see thise ratings on the back? If it passes it gets a stamp. Ur rotella shell crap is rated at "x" and walmart is rated the same.. The same? No. Shell is know for throwing crap in, is it better? Yes and no, shell oils have an additave that when not changed on time will churn into a reddish film, i have 2 hundais a toyota and a 2003 chevy to prove it sitting n my driveway right now.

Walmart is just synth, no add in crap, just slippery dead dino.
Buy walmart synth and ull never go back,

-12 years mantaining small civillian motors.

Shell needs to stay with big throw diesel.
Btw; shell= BP other words brittish petrol.

Its all personal exper. You can take it or leave it, people get crazy with oil for one reason, THEY WANT TO BELIEVE. Like zmax.. Google it. Its mineral oil. They were sued for it.

Make ur own conclusions, im just sayn what ive seen

zinc used to be in conventional oil until the EPA decided it was harmful to the enironment. zinc, or zddp is important for those of us running flat tappet cams...so yes, zddp content is indeed something to consider when selecting oil depending on your application.

once again...everything you ever wanted to know about oil

[Firebirdjones]

I'm sure you've had good experiences when you say you do, but without UOA samples to tell you exactly what's going on and what's in the oil, we don't really know what works and what doesn't.

Yes, and Amsoil has a new oil out now (hotrod series) with very high levels of ZDDP. Looks promising.

Thats true, i forgot about ft cams.
