Royal Purple

[mvfd70]

Any one on here use royal purple synthetic oil? What are the pros and cons of it? I've seen it advertised and it looks good, but then the whole point of an ad is to get you to buy. Let me know what you all think of it.

[RACINJASON22]

Ya got that right about the ads. IMO most all of Top End synthetic oils are real good I use Red Line (just because thats what I have always used) in any race application but I'm not gonna tell you that it's better than The Royal Purple brand. (Piece of mind for useing it in my case)Only Cons I can see is the price.
There are advantages IMO. I have actually seen dyno results where useing full synthetic oils gain hp. Not alot but some. Hope it helps just my .02 on the subject. RJ22

you know I can't explain this because like those ad's say it is supposed to be good oil but I can give you some hand's on effect's of it ,
I worked at a shop as a mechanic when that stuff got popular and like everyone else I thought it would be great , the shop was a kawasaki motorcyle shop btw , well people started running the oil's the synthetic's and the royal purple stuck out in that every bike that had royal purple in it had major engine failure's , to be specific the top end would go fast they would wear the lobe's off the cam , the rocker's would look like they had been on fire !! , then if the customer kept using it after I did the top end it would do it again and then the bottom end's started failing ? note that a lot of these machines were brand new with very few mile's !! after a while and I'm sure more shop's than mine had the problem the main headqarter's for kawasaki sent out urgent bulletin's that stated plainly on all sale's to tell the customer up front that if he or she used a synthetic oil (ROYAL PURPLE SPECIFICLY) that they would not cover ANY engine part's under warranty !!
now the other oil's like redline and klots never caused as much damage as the royal purple did but I did notice all the engine's I had apart that had run any kind of synthetic oil had more wear than normal for the year of the machine and the mile's ,,,, so take that for what it's worth ,,,, myself I use the cheapest oil the auto part's counter man will sell me !! have been for 30 year's and never had a problem ,,,my opinion castrol normal oil is about as good as it get's ,,valvoline is good havoline is ok ,,, quaker state is also supossed to be good now but I tore to many engine's apart in the 70's and 80's that had all that sludge in them from the quaker state oil I will never even cosider it as a choice ,, anyway my $.02 is DON"T USE SYNTHETIC

[RACINJASON22]

....hmmm... I'm not going to say what 19673ontree said is wrong by any means it was first hand knowlege and there is NO BETTER THAN THAT.
But I am wondering if it may have more to do with the way the two (oil and bike design) matched up. Not saying either is bad BTW.

I have never heard any thing like this in the automotive area but I may not have been listening well enough. In fact every thing I have learned about the full synthetic/race synthetics has been the oppisite of this.

Any test I have seen actually have shown LESS wear in fact.

I'm sure there will be alot of other comments on the subject, specially with all of the oil issues being seen today I.E. Zinc addatives (another can of worms)

I for one will be watching to see others comments. RJ22

Horsepower TV just did a heads up comparo on an LS1 with conventional everything (all lubes), then replaced all lubes with the Royal Purple versions and gained 8hp.... FWIW

[19673ontree]

I agree that these oil's are advertised as the best !!
but as I said I had those worn part's in my hand's out of engine's that I know were serviced properly when new because I serviced and sold them new !!
I don't understand it but it was bad enough for a major company like kawasaki to ban it from being used in their product's ,
I thought about the bike verse's car thing to but as a life long mechanic to me an engine is an engine ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
heeeeeeeeeeyyyyyy !! let me tell you another story this happened down at pigeon forge tenn at a car show swap meet piture this !!!

a guy has a stand selling an engine oil or oil additive I don't remember which but anyway he had an engine up on a stand hooked up so he could start it up ,,, it was a 60's 250 chevy six cylinder , it HAD NO OIL PAN , he claimed that it had been pre run with his oil and that after his oil had been in it the engine was protected ,,,,,,,,,,,,,
he started it up and ran it for a while and turned it off and asked if anyone had any question's ,,,,,,,,,,,,,, they were several people there too ,,,,,,,,
well being the chevy nut that that I am I put in to waving my arm ,,,,
he said YES SIR WHAT WOULD YOU LIKE TO ASK ?
I said this exactly ,,,,,,,,
THAT IS A 250 CHEVY SIX CYLINDER ISN'T IT ?
(HE SAID) WHY YES IT IS
(I SAID ) WELL WOULDN'T IT BE BETTER TO USE SOME KIND OF FORD ENGINE FOR YOUR MODEL BECAUSE THAT 250 CHEVY SIX CYLINDER WILL RUN WITHOUT OIL ANYWAY !!!!!!!!

THE CROWD BURSTED OUT LAUGHING !!!!!!!!!!

I COULD'NT HELP IT HAD TO DO IT

[69ChevyLB]

I drive a truck for a trucking company that puts synthetic oil in its new diesel engines after the first 50,000 miles and has never had any problems. Some of these trucks are pulling gross loads of about 79,000 lbs. every day, 5 days a week.

[RACINJASON22]

Ya got a point there 250 slant six dodge the same thing goes. I have been there done that.

? don't know but till I figure it out I am affraid of the oil's

I think this thread will go on forever. A few times I thought about bringing this subject up myself. I have been around military aircraft & even the space shuttle in the past. They all use a synthetic oil in everything from transmissions to engines and any part that uses a grease 99.9% they use synthetic and each item has regular scheduled close examination of samples. Engineers design & recommend. And even under those extreme situations they have bearing failures & gear failures due to whatever reason. I know after we used synthetic on military aircraft the intervals on oil changes were extended to more than 4 X with very few oil related problems & running componets with out any lub (due to oil leak or pump failure) in an emergency is authorized in certain cases with out replacing the componet. Personally I think synthetics with todays advances are the way to go.

I have used Royal Purple in everything I own. I have never had a poblem, and love every product of theirs that I have used, from trans fluid to gear oils and motor oils. I agree with RJ22 in saying it all depends on the application. -Nate

[RACINJASON22]

For the life of me though, I can not figure out why......hmm.....I really want to know

[mvfd70]

Thanks everyone for your input. I use casterol syntec full synthetic in my 97 GMC daily driver. I've seen Royal Purple and other "higher end" synthetics advertised and have wondered if they were any better or worse. I found the posts about the motorcycle engines to be interesting. I too thought that synthetics were supposed to DECREASE wear. But like the man said, he was right there and tore the engines down himself. Maybe it was the engine designs that were not compatible with synthetics. Who knows. Either way that is interesting to know.

One more quick question. For those that use synthetics, how often do you change the oil? I've heard that it still needs to be done on the 3000 mile mark. I've also heard 5000, 7000, and all the way up to 10,000 miles.

I like Mobile 1 and I talked to a guy last weekend that builds dirt track race car engines in the KC area and he has always been impressed by Mobile 1 synthetic. Said he has never had a bearing failure in an engine using that oil. The problem he has now with mobile 1 is that the cams go flat at an alarmingly fast rate. Apparently its because of the missing Zinc, that is what bothers me because apparently only several brands still have Zinc added and mobile 1 isn't one of them.

Second question. I'm not gonna say cause there is NO right answer to that IMO.

Owner Operator call there.

I have heard all that 5000, 7000, 10,000 mile jazz too but here's what I do.

Street engines Mobil1 full syn. 4000

Race applications Red Line 4 Races or 4 weeks, which ever came first, Sometime I seen 4 tracks in 1 week end. Maybe a little overkill here but, guess what I never had a problem that I could say was oil related EVER.

[RACINJASON22]

Straight from the horses mouth. They have lowered there zinc content as most all of the others, so there deisel grade oils have to be used in our older flat tappet cammed engines as well.

Mobil 1 15W-50 provides higher viscosity, designed to provide extra protection for performance vehicles and vehicles that operate in severe service, such as towing, hauling and racing. Additionally, Mobil 1 15W-50 contains higher levels of anti-wear (ZDDP or Zinc DialkylDithioPhosphate) that may be required for certain racing applications and camshaft designs.

you also need to take into account that your are not supposed to use synthetics on a new motor or else the cams, cylinders, and crank won't last , the problem is that with synthetics the surfaces never get a chance to seat and wear in good to one another, like 69chevylb stated about the trucks running syn's after 50k this is the main reason for it because conventional oils allow for more "break in",

and for question 2 i worked in a shop while i was in high school , it was me and the owner were the ones that worked there and he used mobil 1 in all his vehicles he has a 92 s-10 and he ran 5000 on and oil change and out of curiousity we sent a sample off and had it tested and the result suprised me that it was only about half wore out, convinced me but this is only my opinion

[franks72]

I had a 71 nova streetcar. Motor was a crate LS7 454 . After wearing out the factory gm valve springs I changed the hole valve train to a full solid roller setup from crower cams . After being in the car for half a season it messed up a lobe on the cam. My motor guys that I use never saw this befor so they called David Crower . His first question was what oil was I useing , I was useing Mobil 1 .. They explain why they DO NOT like syn oils . Also on there website if you go to the faq section on the site they explain it in detail.
So got a new cam , went back to castrol 10/40 went 3 seasons shifting at 7000-7200rpm and driving on the street to car shows . the only thing I wore out was valve springs ..

[GREASEMONKEY72]

i hear that synthetic oils are better but i just use good ol 20/50w valvoline racing or halvoline racing cause i hear that the zinc is still in the racing oils, but im tryin to get a buddy of mine from out of town to get me some Kendall oil

and i change the oil every 3 months since i dont hit the 3000mile mark


and we change the oil in the race car every 2-3 races, useing valvoline racing 20/50w(dirt track)

[19673ontree]

right here in this post may be the answer to the trouble I had , the machine's that this happened too were to be exact ATV's they were 300 400 500 and 650 kawasaki 4wheeler's and they were brand new , so above statement that you have to put 50k miles on an engine before you use synthetic would explain that , in most case's with those ATV's one of them that is 10 year's old won't have but 2k the 3k thousand mile's on them because they are rode out in the wood's where you can ride from friday till sunday and only go 30 to 40 mile's , so the synthetic won't work in those if this is true , and after reading that and remembering that I also have heard that somewhere else concrete's my thinking I AIN'T GONNA USE IT PERIOD IN ANYTHING !

[mnunn454]

Not to steal the thread, but to think towards the end of the process at discarding synthetics, can they (rephrase this to "should they") be discarded in the usual manner? Or is there usually a different place (better way) to discard synthetics?

[sodak69c10]

thats a good question i never actually thought about disposing of it, we always just poured it into a waste oil barrel and burnit in a oil furnace in the shop
