If you are running mobil 1 or another approved synthetic then 12-18k miles (or 12-18months), when the oil change algorithm tells you to change it.arckeymolarkey said:Ive gone about 6k on my oil.. oil life says it is 27% but next service in 720 days... doesn't really add up to me. When do you guys change your oil?
So fricking true.ctrlz said:After 957 oil threads, the correct answer is...
Yeah, I'm none too happy with this dealer. Unfortunately they are the only dealer in the area. You are correct, the interval is supposed to be 15k and no I am not driving in extreme conditions (St. Louis) with the exception of the roads... Ugh! I hate STL roads (interstate and all). And my driving averages more on the conservative side but I take many short hops (to/from work) which is more harsh on the engine - possibly could be the reason.JonV said:IMO I'd get a different Dealer to check out your electronics, that sounds Very extreme. I "Think" 06 was the year the Interval was changed to 10K from 15K. Unless you are driving in extreme conditions or an extremely aggressive driver you should easily get to 9-10K on the Oil Life Algorithm.

On the 06 models:
IF it's been one year since the last oil change, THEN change it as the SID is reminding you to. Reset the oil life monitor.
IF the oil life reaches 0% THEN change the oil, as the SID is reminding you to. Reset the oil life monitor.
This is also counted as one year since the vehicle was built. Mine requested an oil change in June of 07, it was built in June of 06, even though it didn't go "into service" until Sept of 06 (warranty expires Sept of 2010). So if your vehicle sat on the lot for a while before you bought it, this maybe why it requested an oil change so soon. You can see this under "Days to Service", it counts down from 365 as soon as you reset it.
Oh yea..if you're halfway good with math you can figure out how many miles it's gonna be to get to 0% based on how you've been driving the vehicle (which is how the oil life monitor calculates the remaining oil life). With my driving, it's around 17,000 miles. But I do a *LOT* of highway driving, someone who mainly drives in the city will have a shorter oil life.
It changed for the 06' MY. Alot to do with people not maintaining the vehicles (ie, the ditsy chick driving the fleet vehicle only 8,000 miles a year and never checking the oil). I guess GM felt the cars might get more attention with the lower interval. We certainly know by now that the proper full synthetic can go up to 18,000 miles just fine.JonV said:I though the Interval was dropped to 10K in 05 or 06? As opposed to the 03's/4's which were said to be 15K.
That's funny.JonV said:Days to service does not count down in order....it's based on the Oil Life Service Algorithm, it sort of parellels the percentage.
