Hello,
I bought an 07 Nissan Altima 3 days ago. Last night the oil/filter maintenance light came on and took it back to the dealership today. I was told it came on as a reminder and that the oil change had already been done (and that's probably true, the little sticker on the window shows next oil change is in 3k miles and that it was serviced at that dealership). I had it reset and drove off and light did not come on again in the ~20 miles that I drove today. My question is: Is it likely the light is programmed to come on every x number of miles, even though the oil change has been done?

Some cars are like that (set for ever 3k miles). I had a truck like that once but can't remember which one it was.

My Suburban was different. It measured engine rotations and heat cycles and stuff like that to come to a conclusion about whether or not you should change your oil. There was only one time I can recall that it kicked on before 3k miles. If it didn't kick on by 3k miles I'd change the oil anyway and reset the indicator. Better safe than sorry.

The procedure for resetting the indicator is in the vehicle manual. If I were you I wouldn't trust the dealer and just go get the oil changed. If you have it done at a shop they usually know how to reset the light. Most of the time the procedure is something like turn the key on and step on the gas pedal 3 times.

Yes the car is programed to let you know and make you think you need to take it to the dealer....They make money this way. I am more concerned about the little "black box" the cars have that record your complete driving data AND WHEN AND WHERE YOU GO... They dont talk about this when you buy a car do they?

drjones96 has it. If your car is like mine and my wife's (a Toyota and a Honda), the oil change indicator only goes by the odometer. It sounds like the tech who did the change accidentally forgot to reset it. No big deal.

Hmmmm.....sound like a load of horse manure to me.

Me thinks you better have another mechanic check this out before you burn the engine up.

Damn, some dealers can be such liars!

jones and whiteboy got it.

The light couldn't be reset if it hadn't came on yet. It reached the 3k mark since the last reset 3 days after you bought the car.

This is from Ford. They're all basically the same.

When should I change my oil?
Many 2011 model year Ford vehicles are equipped with an Intelligent Oil-Life Monitor (IOLM). The IOLM uses actual engine operating conditions to calculate the oil change interval by using an algorithm. The IOLM will indicate when the oil change service interval should be completed by displaying ENGINE OIL CHANGE SOON or OIL CHANGE REQUIRED in the message center.
The system requires you to reset the IOLM after an oil change. Missing a “reset” at an oil change will result in a premature OIL CHANGE REQUIRED message.

IF there is sufficient oil in the car, how can you burn the engine up? Do the Jiffy Lube oil fairys visit after 3K miles and cast a spell to destroy the engine for those that go longer? I know oil breaks down and gunk can become an issue, but burn the engine up?!

Honda maintenance minders are not driven just by the odometer. The oil life indicator (% of oil life) considers temperature, length of drive, and elapsed time/distance.

I don't know about Toyotas.

Yup, once oil becomes "gunk" it won't flow through the filter. Same as no oil in the crankcase.

I don't know about Toyotas.
BMW have for a long time had an oil change and maintenance minder that looks at coolant temp, time spent above/below a certain RPM (varies with model) and other parameters that I don't recall off the top of my head, and it asks for "Inspection I" or "Inspection II" service respectively based on how you have been driving. Probably the Honda system is similar.

These are OK, but it's important to use the oils and fluids specified by the OEM if you want to use these service intervals, which are on the long side.

Keep in mind too they don't consider things like a dusty environment, that could mean a shorter OCI would be prudent.

Very few modern cars require a 3K mile OCI - although without knowing more about how you drive the car, and where, and what oil/filter you are using, I can't comment intellegently on an OCI for your car.

Take a look in the owner's manual, you should find a recommendation for "normal" and "severe" service OCI.
