I agree, when I change my oil I have a hard time finding it on the dipstick. I have to roll it on a paper towel to find the mark.Why is the oil black ? They didn’t even change it ?
My stealership has "warantee for LIFE!!!" (probably worth as much as a few sheets of TP). They mandate that you get maintenance at the stealership or get permission from some 1-800 number before having someone else do it. They mention that you can't DIY and keep the "coverage". My boss had a dealership add oil without draining it first, and when he took the car back to complain the service manager told him "How do we know YOU didn't do it". That was his last "FREE" oil change.
