Mobil 1 or Royal Purple

Re: Mobil 1 or Royal Purple

I've been religious about M1 in the Omni, Ty, and the SS, but recently I've been considering going with Castrol Syntec.



How do you tell if it's German?

The SLX is a german (european blend) synthetic, basically approved for use in german (VW, Audi, BMW, Porsche, MB)

Re: Mobil 1 or Royal Purple

I've used mobil1 on all my cars with no issues, but my zr1 is going to get joe gibbs latest snythetic.....he puts the engine first and hasn't removed or decreased all the good stuff that race type engines need. The only bad thing is my z swallows ten quarts of this at a time!$$$ joegibbsracingoil.com


I use castrol 60w in my zf six speed.....had to go to the bmw dealer for it, but is the only oil recommended for any zf 6 speed. It lowered the gear noise from the use of an aluminum flywheel to almost nothing. From what the bmw parts guy told me this castrol 60w is all that's used in there M motors/cars and can not be purchased from places like checker or vatozone.

Joe Gibbs Driven Racing Oil contains all of the correct additives, like Zinc, Phosphorus and Sulfur in addition to the highest quality base oils to protect your engine.

Re: Mobil 1 or Royal Purple

Mobils website claims it's still "fully synthetic" and not a "blend" FWIW. I like mobil 1. hey Don, I believe your bearing problems were related to detonation(reading your old posts). Good old Sy's and Ty's apparently don't like to blow headgaskets so the bearing take a hammering. I don't think the oil would have made a diference. Just my opinion of course.Also, I'm jealous of how fast your "stockish" truck was running.

Ya I know, I was just a bit disillusioned as to what the other bearings looked like so I had to spout off a bit. Thanks for the compliment! Truck prolly won't race again until next season anyway but that's OK. I can take my time and also spread out the cost a bit.

Oh, I thought he meant made in Germany. So the normal Syntec stuff isn't what is good then I assume?

I have used Mobile 1 Synthetic since 01', I know the previous used it also.

It is made in Germany. Only buy the German stuff!:tup: Its pretty good if you study UOA's on some of the forums like BITOG.

After reading about complaints with bearing wear with the new oil spec, I stay far away from the oils that have it. Just read that Hot Rod article why people with flat tappet cams are having issues. If older engines are having problems, it can't do ours any good.

Re: Mobil 1 or Royal Purple

One thing that not a lot of people are aware of, is the EPA's new guidelines forcing oil manufacturers to remove some very important chemicals from engine oils (to prolong CAT life). Although Zinc Dialkyl Dithio Phosphate (ZDDP) is used to mainly prevent catastrophic camshaft/lifter failure, I wonder if further tests have been done to assess its affect on other 'high wear/friction' areas (rocker/pushrod, rocker fulcrum, etc.) - This is the chemical that the EPA is forcing the lube manufacturers to remove (very important to the solid lifter crowd).

This link has some interesting information that could be relevant to all engines, including ours.... http://www.zddplus.com/

Once again, anyone running solid lifter, or direct cam-on-follower type motors (overhead cams with follower buckets and adjusting shims) NEEDS TO READ the info on the above site.....

My problem is that now my faith is shattered regarding Mobil1... I always thought it was the slayer that dethroned Castrol (what I used to use in all my German cars)... now I'm going to have to rethink this whole issue (haven't kept up on it lately)... thanks guys for all the great info. - that's what I love about this site.. a lot of guys who really get into the details and pass along great, useful info! :tup:

Exactly! EPA has been removing the ZDDP through most oils. Diesel oils still have enough thus the reason to use Rotella and others that don't have the new EPA spec.

The SLX I think is a better oil than the standard Syntec, no energy conserving stamp and is usable in VW, Audi, and I think it was MB.

This is virtually the same oil as castrol syntec SLX only its 0w30 instead of 5w30 and I say that because it meets most the same VW specs(not the tdi specs though) and thats pretty hard to do. Not a lot of oils out there that do. It also meets BMW and Mercedes Benz and the latest ACEA specs. If you want to run a 0 weight than thats the stuff. If you want a 5w30 then run the SLX. I would like to run that 0w30 to see if it gets any better gas mileage.

Also Ry I didnt beleive it when I got the call but all new M series have to take 10w60 from BMW. Pretty badass really

Good to know about the SLX stuff. The 0 weight vs 5 weight shouldn't make a difference. Either one would be a good choice along with the others mentioned above. Its pretty hard for any oil to achieve some of those Euro specs.

Is it "thin"? Come on, 0w-30 has to be watery.
NO! Please don't completely buy into that myth.
* At cold temps, the 0w weight correlates to cold cranking viscosity.
That means GC will still flow at cold temps. (Which is a good thing!)
* At operating temps, the 30 weight is actually close to a 40 weight.
GC is one of the thickest 30 weight oils around.
I don't want to go into too much detail about this here. It can be very confusing.
My point is, GC is not "thin" in most temperatures that we use our cars in.

Re: Mobil 1 or Royal Purple

I don't know if it makes a difference but that truck has had Mobile one in it every 3k since I bought it in 1998 with 52k on it. It ran as strong if not stronger when I sold it as it did when I bought it. There probably isn't to many out there with over 100k that have never been apart. I vote for Mobile One

my ty has had mobil 1 in it since new (as far as i know) and it has over 105k on it.. it has never been opened either.. another ty I had had 198k on it and used nothing but mobil 1.


when my sy is built i guess i'll have to make a decision on what to use.. 1) to break it in, 2) to run in it.

Re: Mobil 1 or Royal Purple

So does that German Syntec only come in 0-30? Is that ok to use in our motors? What about in the winter (it gets cold up here)?

Yes and yes. You actually want a zero weight for the winter but many people have been using in the summer with no issues including AZ. Read the GC FAQ I posted earlier.

For the people that are posting about all the miles using Mobil 1, remember the new spec happened not along ago so the older M1 may of done a great job in the past, but the newer M1 with the newer spec may not. 0-40 M1 is the exception though. I'd much rather run 0-40 M1 that does not have the newer spec than the 10-30 M1 that has less ZDDP. They are taking out important properties of oil that will make the engine last longer but hey, at least your cat. converter will be okay... :rant: Just read the articles to see for yourself.
