Hey everyone. Looking for some advice.
I own a 1998 Grand Prix GTP, 3.8 S/C engine (iron block). We redline at 6000, determined by our oil pressure I assume, and I want to spin my engine a little past that to say 6300-6500. Our engine is rated for 10W30 oil.
People spinning to these rpms currently have said they simply use a good 10w30 synthetic and change it often. I was wondering if I would be wise to use a slightly thicker oil so that it clings a little better to the crank and cylinder walls? Does anyone have experience with this scenerio?
Also at the moment I keep switching between Castrol Syntec and Mobil 1, I can't decide which I like better. Mobil 1 seems to be a favorite on this board. I've also been thinking of trying Redline, I don't mind paying for a good oil. Any recommended brands are also appreciated.
thanks!!
