IMPORTANT: The Chronicles of Low Oil Pressure by 07burb

[Kapitein]

Did the pickup O ring on mine today.

Warm idle has gone from 10-15psi, to 20-25.

Cruising is 40-50psi. Acceleration is 60+. Haven't done a cold idle yet.

07 Denali, 167k miles. Unopened engine.

Did anyone in their travels ever read about the oils that go into our trucks? that it was about having a high quality, something about LL improvers in the formula? this was to assist the DoD from slugging? Sorry about the Babbel-ling-I just stick to Liquid Moly or Royal Purple-I luvs my baby that much! I too eliminated some nasty things to enjoy my truck with no more problems. Did the sensor and filter, stop using more flex-fuel than hi-test + an additive was added (Lucas for E-85), ugh! Sickening! Couldn't be happier for the last 10k miles, with no end in sight! (i change the oil every 5k miles; my truck sits a lot and runs far when it goes) I still love the DoD too!

I spend a fair amount of time @BITOG forum learning about oil, etc. I've been doing UOA on our vehicles for 11+ yrs. 0w-20 oil is a good match with me and my 2007 6.2L L92.

My 2007 6.2 didn't come from GM with DoD thank goodness. I changed the oil pump pickup o-ring 4 yrs ago as preventative mx.
