as for me i have the correct amount..cuz i checked and it's at the midline from the Full and Empty on the stick..so it's good, and i'm running Mobil 1 5w30 full synth..so i dunno wat's going on..
When I first add Mobil 1, and I pull out the dipstick to check the level, I can barely even see oil on the stick.
I have to press it up against a paper towel to accurately see the level.
Maybe your car burns oil at considerable amounts?
Cause when I change my oil, it's as full as it was when I changed it.
