Light weight oil
Anyone drag racing with light weight oil? I'm talking about 10W or less. Who's tried any of the Red Line or Royal Purple light weight oils. What's been the result? How much oil pressure do you like to run? What are your bearing clearances?
I don't care to hear from people with 80 psi oil pressure at idle, so don't chime in. Thanks.

Re: Light weight oil
I put the Royal Purple in my rear, trans and motor (5W30) and going to the track with it tomorrow - hoping it makes a tenth difference. I might dyno the car again next weekend and see if it changed HP - but if the conditions are not the same as the last time I ran it - it won't really matter.
I usually run my tire pressure at 15psi (17" Nitto DR's). But you can run it as low as 10 as long as the tire doesn't move from the rim (I put a mark on the rim and tire with a sharpie and check it out when I get back in the lanes).
I've heard of guys running different oils at the track in their bracket cars - even straght 0 weight. But I wouldn't run it in my street car. I think the RP 5W30 or the M1 0W30 is the lightest you should go in a street car - just my opinion.
Hope that helps...

Re: Light weight oil
I swaped my car over to synthetic oil and a lighter weight oil. looks like some similar racing conditions are going to come up real soon (weather wise). I'll get some results soon hopefully.
The changes should be pretty small and will be hard to qualify.
Don't run 0 w oil in your street car. All the ones I've seen are for racing and lack the additives that prevent sludge buildup. Other critical oil functions necessary for "street use" may be jeprodized.
