royal purple is probably 1 of the last oils i would ever run.. I might try water 1st.. I have seen more lab results to prove that stuff is JUNK than anything else.. Great marketing skills with Purple oil.. Thats about it..

again I dont know much about this topic, but he swears by it and uses it in his race cars and swears that it better then all other brands he has tried so far... he also uses it in customers cars when doing oil changes and they find they get better gas milage and the car seems to run smoother..

 

No RP in a turbo or diesel.

 

I've just found it here at a good price

Does anyone of you guys know the oil brand BARDAHL? It seems to be a very "special" oil, with a proprietary molecular blend that builds a very strong and friction-less film on the moving parts.
Their best oil is sold for nearly 40usd per quart here.

 

For what it's worth, my master tech with twenty years experience says the Mobil 1 0-40W is the ticket for my stock application.

 

I like Motol, but I must be missing something Jugs sell VR1 for 6.99/ qt?
Is this the stuff we're talking about? Here's another opinion http://forums.corvetteforum.com/c3-t...ht-it-was.html

 

nOT GOOD FOR OUR CARS. Stick with Mobil 1 and frequent changes.

 

What other kinds of oil are their? Non-shelf? drums? Floor? Custom?

Seems a funny turn of phrase...

Agree on purple... I'd sooner run snake oil....

Why? I have never heard bad inout on Motul.

 

I have had 3 race cars set up for drag 1/4 mile from 14 sec to 9 sec range and have only used CASTROL Oil on all. Now for my stock street cars, I have always used the factory recommended oil, including Mobile 1 (when specified) and have never had a problem with either.

 

Not recomended for boosted our engines that are normally opposed.

 

I run Motul 300V 15w50 in mine based on recommendations from a local tuner

 

so which is the best oil for our engines? are some people switching from mobil 1 to another brand because mobil 1 is not the same oil it use to be?

thanks

 

I'll wait for the Mobil 1 racing 0w-50 oil to be available in europe. Otherwise I'll try Castrol 5w-40 or Valvoline 5w-50.

Anyway, I'll keep my service intervals below 3-4000 miles or 1 year, and I think this is the most important factor after all.


If someone of you guys wants to use a racing oil, keep in mind that those oils require more frequent changes, because they have less detergent agents, so if you run them for too many miles you are building sludge in the engine. And, since they have high % of zinc and Phosp. they can be dangerous for your cats.
