does anyone use royal purple or mobil 1 oil with theses turbo's..

if so what boost lvl and how many miles on it?

 

i have only ever used mobil 1. mine is at about 8000 miles, at about 27 psi with no problems and alot of racing

 

there is a recent thread covering this topic. i think its called "attention fp black users" or something along those lines.. alot of info in there

I say don't risk it use what FP recommends, is saving an extra few $ a qt worth the risk?

 

it just seems fishy... i mean the FP red has been out for years now n this is just coming up now?

 

Seems fishy how? You think FP just decided they wanted you to spend more on oil all of a sudden?

 

when the FP reds came out, "years ago" they never had said any of that. They would of had paper in the box with the FP red and black saying u need GF-4 oil... i got my black 5 months ago didnt come with anything but a card for a year warrenty...

Royal Purple has kept their SL formula for most weights because they feel it is a superior formula to what would be required to meet API SM. The change to SM required a drop in ZDDP to supposedly protect emmissions systems but in many people's views it has come at the expense of wear protection.

 

I've been running Mobile 1 synthetic and just hit 81,000 miles. Car still runs like new

 

u dont have a FP turbo tho

 

I'm aware of all this, I fail to see what point your trying to make. If research from FP has determined that what they thought was best at one time isn't whats best anymore then whats the problem?

 

idk... i love my FP turbo, but i think they had to come up a solution to why some were going and they had to make an answer.. and that was there solution. Its because of the oil.. im not saying they are wrong, but i dont think they r right

 

You think FP would make an official release on a whim?

Youre overlooking that oil composition has changed in the last 5 years. Most manufacturers took zinc out, which is what steel journal bearing turbos need. I know of several customers at the shop I work at with muscle cars have wiped out flat tappet cams because of the new lower zinc content

 

You think they are adding these to every new turbo for nothing? If your
oil isn't on their approved list and they test the oil in the turbo your warranty
is gone. I wouldn't risk it.

I see RP on the list tho. but 14 a qt? lol. Why run that when you can get better for cheaper.
