Wow I haven't been in here in a while.....So I've had my speed since April and I'm getting ready for another oil change and I was looking around and just curious as to what everyone else was running in their Speed. I originally thought my dealer mentioned something about Penzoil but the next oil change I asked my fiance, he is into cars but he really owns a body shop, he told me to put Castrol GTX 20/50, well I went to go buy some oil again yesterday and his friends works at autozone, (thats the only reason why I went I know all the workers lol) and he told me he runs synthetic in his Scion TC (which he thinks is the greatest thing ever and he races people but its pretty much a ricer
) anyways he told me 20/50 seemed kind of thick but I dunno I guess I'm just wondering what the majority is running out there or if I am supposed to have something specific in my car, it would be a nice thing to know....oh and 5.7 quarts geez! My fiance's 07 z71 4 door chevy takes that much lol anyways just would like some feedback thanks!
