987 Service Question

I agree, I'm not going to run to the dealer any time soon. I've got a pretty good idea of whta needs to be done and when thanks to this forum.

I'm not sure if the 987 computer counts down on the time as well as the mileage, but in your case it seems that it does.

Eighteen months is a long time to be running on the same oil...

The manual for the 06 says 2yrs or 20,000 miles for first oil change.

I'm going to give the dealer a call regarding the countdown timer and will advise here. Like I said previously, I'm not going to rush in there blindly. In my opinion, at 7K miles the oil is fine despite 18 mths. Engine use and wear / tear on the oil is what breaks it down, not time in the crankcase. Would anyone throw out a jug of Mobile 1 that was 18 months old? I doubt it.

That does sound logical, but then, I've always gone by the recommendations that state that oil does have an "expiration date", so to speak. If it is just marketing, I have yet to meet a mechanic that refutes it.

Let us know what the dealer tells ya.

Did the dealer give you any guidance?

I've got a similar thing going on with my 07 987. Got it last August, put it up in late October for winter and just got it out again about 4 weeks ago. I've got 2600 miles on it and now the indicator light says "Service in 29 days".

I can't for the life of me figure out how to reset the thing.

If I can give my opinion on the subject.

Oil does not have an expiration date. I've never heard of such nonsense. If oil did have an expiration don't you think the black crap we pump out of the ground would be worthless?
The reason for the time & mileage change of oil is because of contaminates and viscosity breakdown. Man made synthetics don't suffer viscosity breakdown like crude oil does but it does still get contaminated. The contamination comes from cold engine start-up when the fuel is enriched to keep the engine running until the pistons, rings, cylinders and valves heat up, expand and seal. Until then blow-by is occuring. It also comes from time and weather change in the form of condensation (water) on the inside of the block. Then there's the dirt and carbon that oil picks up on its way through the engine, building up as time goes by. This combination can also make an acidic mixture.
The way to combat this is to run the car for extended periods to burn off the contamination and storing the car in a climate controlled environment. Short runs and not letting the engine get up to temperature build it up.

I think what your computer is telling you is that the internal clock, not mileage, has gone off and it's time to change the oil.
