G8 Oil Change Kit

[Greg@PacePerformance]

OK Castrol makes the oil for GM but I can't seem to find it on the Castrol website for any specs. It is called Castrol SAF Carbon Mod.
From what I can find on the web about it that lub is a 75w90 Synthetic fluid.

So I guess right now this Royal Purple 75w90 Gear Lube would work

Got my Pace oil package in the mail on Wednesday....boy did the post office have a field day. Box was bashed in on one corner pretty good. Fortunately, everything inside is fine.

Thanks again for the deal and speedy shipment.

Guess this is a good place for a story (I think I've told it before on this forum, but here it is again). I used to run Red Line in my race car, based on some "independent lab tests" I had read. Then I witnessed this.

Friend that I race with has a GT1 Corvette with a 400+ci SB Chevy motor in it. The motor makes 700+hp, has 12+:1 compression, redlines at 8500rpm, and has a dry sump oil system. He was racing against a guy whom he had never beaten, and was sticking on his bumper in 2nd place. 2 laps to go, and his oil pressure goes to 0.

He decided to go for broke, and never came to the pits. The car completed 2 whole laps of hard racing with no oil pressure. In fact, he was able to pull the car up in the trailer when he got to the pits!

But, the story doesn't end there. They brought the car back to the shop to rebuild the engine. Just for kicks, they tried to start the car after it had been sitting for 3 days. It started on the first try. Seriously.

When they tore it apart, there was all the usual carnage (melted pistons, bent pushrods, etc.). But, he had Royal Purple oil in the car. While I'm sure that things like hardened pushrods, lightweight valvetrain, and other things factored into the engine surviving, I know the oil helped.

So, I now run RP exclusively in my cars. It's in my G8, my Trans Am, and my wife's Honda Pilot. Heck, I even put it into my 1986 Chevy 3/4 ton tow vehicle, just in case.

Matt: Good story, I was planning on either going Mobil 1 or Royal Purple. But that story has me sold on Royal Purple.


Greg @ Pace Performance: I will definitely be ordering a package soon! Sweet deal.


* Question for all: If I put in Royal Purple can I switch to Mobile 1 or once I go with a full synthetic should I stay with that brand?

Thanks!

RP is a full syn.

RP is a full syn.

Ray: I understand that Royal Purple & Mobile 1 are both full synthetic oils, but I was wondering if I put in Royal Purple first, can I switch to Mobile 1, and then go back to RP, or once I go with a brand weather it be RP or MB1 (full synthetic) should I stay with that brand?

Just curious....

Sorry Mike, I misunderstood. According to RP, you can change over any time. I don't know about Mobil 1.
