Re: how often do you do an oil change?
You reset after each oil change....(it resets to 7000),....but that doesn't mean after 7,000 miles it will tell you to change the oil. If you drive 65 mph all the time at 72 F....it would probably really let you go 10,000 miles..(it counts down to zero)..if you drive at redline constantly....I don't know...it probably would tell you to change it after 4-5,000??
Chevy's oil life monitor (not synthetic oil) let's us go 8-10K on our HHR....so I have no problem with MB's oil life monitor (synthetic oil)..allowing >7K miles....besides , like I said before...as long as I keep receipts & take it in for the free inspection every 5 years as required......it's got a Lifetime Powertrain Warranty....what do I care if it has an oil related failure!!
