Hehe, thanks. The filter is made by Fram and the p/n is PH3387A. The oil is Quaker State.

same here no problems yet

Fram? bleh. lol Did it do that with anything other than a fram filter? I'm curious if the fram filter is the cause of your oil pressure spike?

Correction. The Fram was from a previous oil change, the latest is a WIX p/n 21040 filter. Somehow I knew someone was going to say something about the Fram filter, lol.

Why not leave well enough alone and continue using the manufacturers recommendation?

Apparantly LSx engines LOVE 10w-40. It does offer more protection though then 10w-30, but wont flow as easily.

I run 10-40 in the summer months, it'* harder to burn off with hard driving, and trust me, I flog this car. Also helps everything run a lil quieter, like the lifters and all. In the winter I run the 10-30 unles we get a huge cold snap, then I'll run 5-30 and just have to be nice. 10-30 is recommend for all SSEi'* I think?

Changing the weight of oil though I don't think really protects you more....I don't think? And if you were to change the oil in your car, I don't think you'd benefit from it much more than normal oil.

i did run 10w-30 but on the last change i used 10w-40 and have a little less pressure while driving but more at idle

The weight is a measure of "protection". This is why stuff like royal purple will increase horsepower, it'* VERY thin, and almost water. Fine if you rebuild your engine all the time. Pure **** in a daily driver.

I use 10w30 all the time. Idle around 40-45, 55-60psi normal driving.
