Rotella FTW, I run rotella in everything I have and I stand by it 100%, IMHO the best conventional oil for the money.

Re: What weight oil do you use?
 

I've had an oil psi gauge in the car for the past week or 2 and I have a good idea of where it sits. Normally it idles at around 11-13, at 3k RPM under load its about 70-75. However when it gets really hot or the car has been running for a while, idle has gone as low as 6... a bit scary. And 3k rpm will drop to 60 or so. Should I be worried?

Re: What weight oil do you use?
 

I would say run a little bit thicker oil. I have the original 6bolt in my car with 70k original miles and idle is around 20psi and 3k cruising on the freeway its at 75-80psi. That's with 10w30 also. The manual says no less than 11psi at idle.

I'm already at 10w-40... might have posted that in this thread. Should I go to 20w-50?
