No, but what I HAVE heard (seen no real data) is that RP is not good for the tranny.
I find it hard to believe, but all of this stuff IS chemistry, so who knows.
I'm going to go to M1 for the tranny next month.

I was told that if I don't use Royal Purple engine oil, my engine will blow up.

I just switched to Castrol Synthetic 5w30 yesterday, and I got yelled at by my friend.

Is he crazy?

 

Not only crazy, BUTT-stupid.
Any oil that meets SAE standards is fine.
Some are obviously better.
Castrol Syntec will be a great oil.

Enjoy.

 

I use 10w30 Mobil 1 in the winter, summer i use 15w50. But then again, its always summertime in San Diego Ca

 

15w50 is NOT good for a tC.
You ought to rethink that.

 

Really, some of my friends that are boosted like 15w50, cuzz its thick.

 

they're boosted....ur not

 

I use Greddy 5w40 turbo oil

 

Dealership changes my oil for life every 5k miles.. I'm only at 8k miles :D

Any idea what they use?

 

5w 30 Mobil 1 Full Syn.

 

Dude, you've never even seen my car If i were you, i'd leave- it at that!!! And i meant 5w50 not 15w50, my bad on that part

 

Yo Greg, Phill's not letting you or Chris post on SCTCC anymore?

 

UNLESS YOU'RE BOOSTED THAT IS STUPID.
I haven't seen your car, nor do I care.
But if it is NOT boosted, you are risking you engine.
PERIOD>

 

Royal Purple.. enough said

 

I wasnt talking to you. If you have a built motor without boost, you need to run something a little thicker. Ask someone with a built motor, cuzz you aint gettin it. Nor do I give a **** about your car!!!!

Wow.
50 weight oil is NOT a little thicker.
And "built" is what?
How much HP?
What mods?
I said I haven't seen your car because you said that to the other guy.
Wasn't a diss - I'm trying to help you burn the right oil in your motor.

 

according to ur profile here chris, you've got bolt ons...which dont make ur car built...

and i saw ur car the first time u came out to a meet chris....

 

So whats the best weight and oil for a Turbo 300whp+ tc??

 

Depends on how you get that 300whp.

 

Ok, now he's saying my engine will 'IMplode'.

Now I'm just plain scared to start my engine... Why is everyone so brand loyal? Are these the same people that buy everything they see on tv commercials?
