I had a oil change on my E430 at 70150 miles and now with 73750 miles on
the car, the service light comes on. I thought the E430 would run more
than 3600 miles between services, I've read the car should run some 10,000
to 12,000 miles between services especially in California. I noticed on
the last service the mechanic put in 9 quarts of Castrol 20/50 oil . I
don't misuse the car, just normal city and highway driving, put 3600 miles
in the past 6 months.
Is this normal? Looking for your expert opinions and suggestions.
I'll bet that MC is correct.
I have my oil changed every 10k because I don't trust the FSS. Two out of
the three services (I have 33,000 miles), my dealer did not reset the FSS.
Worse, on my second oil change, the low oil indicator came on after a couple
miles. I find it hard to understand how anyone can forget to reset the FSS
after servicing. It's gotta be second nature. This and other reasons, I
have lost confidence in my dealer doing quality work.
To the point - your oil service light is probably an indication of the same
poor quality of service!
