Do tell!

I could understand nothing but oil, only the word oil. Today while I was fixing and straightening up the store I saw one bottle of SAE-30, I looked at the price and it was $1.50, I read the label and it said "non-detergent" what is this stuff?

What type of oil should I run in the motor, the synthetic oil or the regular oil???

[89 crew]

I forgot to mention, I prefer the AC Delco. The Wix or Napa gold filters I believe filter too small of particles. I use those when I buy a truck with a good engine, but I usually have to change filters 3-4 times before I can go 3k between changes. I use the Delco for every day use. These filters were originally made for school buses with the 366 and 427 engines if you ever have to look them up. For oil I run Mobile Delvac 1300 series 15/45 add 1 can of stp, and 2 oz per qt of "Energy Release" additive. With that combination I currently have a 427 with 16500 hours on it and still runs strong! My 350 burb has 432000 miles and is a daily driver. carrys 45lbs hot at idle, doesn't even get hot running ac in town in summer. it has had the intake gaskets done at 410000 miles but that is all inside the engine.

I use these

I got that one on my truck. I was wondering who makes napa's air and fuel filters?

[89 crew]

I'm not sure about the cheaper models but the Napa gold is a wix filter.

[Brock]

I had an uncle that NEVER changed oil in anything...he would change the filter and top it off, but never actually change the oil. The funny part is every single vehicle he had survived 300000+ miles.

[89 crew]

He was probably running the france filters. If so he probably added stp or some other lube back to the tired oil

[BLACK AND BLUE 67-72]

Wix makes NAPA's Pro Select filters as well as the NAPA Gold filters. Pro Select filters just have a few less pleats in the paper than the Gold. Also if you have the room run the 1794 NAPA or the 51794 Wix filter, just for the extra quart of oil.

I wonder what they would say if you put in Flag non-detergent oil, or a recycled oil of some type? – they are all the same…..

Ask a crop duster or a member of the CAP--- you would be shocked ------ IT JUST DOESNT MATTER ------ as long as its fresh and topped up and as long as you don't mix synthetic with mineral.

Viscosities mix readily ------- Auto people lay much more importance on this b-s than av people ---- but i'm talking about people who use their planes hard, not folks with a Pitts Special who uses it 10 hours a month. A plane is a big investment, and many people rightfully treat their investment like i would treat a Lotus -- but in either case, its not totally necessary , but owners do what owners do

Av gas has the advantage of lead. While yes these trucks were designed for lead they were not designed for surfer which replaced lead. start putting gas station gas in your plane and see how far you get! That is the reason for the different opinions! While the recycled oil, and non detergent oil will work fine with lead, they won't work with the sulfur based fuel we are forced to burn in our trucks without something to stop the sulfur from becoming sulfuric acid. without the additives, sulfuric acid will eat your engine from the inside. try what they said and then let it set for 1 month and you will have pits in the cam, lifters, crank, and bearings where the oil stayed in contact. that is the purpose of the detergents in the oil, to stop it from causing problems.

Probably going OT, but I call complete I don't know anyone that owns their own aircraft that doesn't use a top-quality aviation oil.

[68C15]

in my opinion you should shorten up the 3000 interval. it sounds like you have combustion gases getting into the oil and making it black. have you done a cylinder leak down test?

[smitty62]

A-the oil should be black if it's doing it's job--change oil and filter (preferably Wix) EVERY 3000 miles.

B- make sure carb is not too rich and choke is not opening too slowly

C- Ignore ALL suggestions of ANY oil additives--I cannot believe that people still buy this crap. I guess the oil and vehicle manufacturers are all idiots??
Dump your STP, etc, etc. on your Coco Puffs in the morning--it will do you more good!

And I thought my K&N filter comment would stir the pot…..But this should get it going!!

I agree - with the exception of ZDDP additives if you're running an oil that doesn't have the recommended amounts for your flat-tappet cam. Most of that junk just clogs oil filters.

Junk. Put it in your lawn mower if you want. Why would you pay to rebuild your motor then run that crap in it?

Sorry about the thread hijack, i just found the plot twist interesting.

Most people would use only the best i agree, -- when you have 75 - 200k (or more) investment - $100 for a case of oil is no big deal -- but not all

My father worked for the FAA for 30 years as a field safety investigator. I worked as an apprentice doing the same before settling down at Cessna in their experimental department. Part of the job with the FAA is dealing with the low budget operators(cropdusters, CAP people, low budget cargo operators) and type certifying home builts and things like that. In that environment you see anything and everything and you quickly learn there is more out there than hobbyists with their Mooneys and Bonanzas sitting in brightly lit hangars with checkerboard floors.

In the experimental dept., we tried everything in a somewhat controlled setting to get planes to fail as well in both static and flight tests

I haven't seen it all, but i have seen a wide range of oddball setups (the worst is the crop dusting field -- where a plane is regarded as a tool, no more or no less important than a tractor)

I have as much respect for a horizontally opposed Lycoming 4 or Continental 6 in the durability department as i do any small block chevrolet

nope, but a 350 sbc should in theory be less sensitive to oil differences than a plane from a maintenance standpoint.

70 GMC'er needs all the reliability he can get in case he has to outrun the long shotgun barrel of somebody's angry husband/dad. But i don't think he wants to put the car wash discount in jeopardy just yet

Once again, I completely and strongly disagree. 350s are set up with far tighter tolerances than an aircraft engine - you know that as an A&P - and we get higher HP/CID than an aircraft engine. What specifically do you base your "in theory" on?

I guess I'm beating a dead horse here with this back and forth, you're generalizing from your experience (which is far different from mine after 10 years of flying just about everything with a prop from experimentals to warbirds) and I just don't see that it's valid.

So if I need to outrun that guy, how can I make the truck get more horse power? One day I asked my auto tech teacher about how to make my truck faster, and he told me to put a chip in it. Was he talking about a racing chip?
