I searched and saw this issue touched on, but never a definitive answer, so:
Engine starts and warms up slightly above 50 psi, and once it's hot, it will settle down to about 12.5-15 psi at idle. Lately it's been in the 80's-90's here. I run Mobil 1 5w-30, and there's 123,xxx miles on the engine, never rebuilt. It is an autometer gauge. Earlier this year, before it got hot outside, the lowest it would ever go is 20-25, using the same gauge and weight oil.
Once you touch the gas, it will go back up to 35, and will stay at 35-40 while cruising at 2000+
What do you guys think? Reason to worry? Should I just switch to 10w-30 and see what happens for the summer?
Thanks for the replies!
