I bought my Cobalt back in October and as of today I have 22,700 miles on the car (about 2500 miles per month). I drove it about 110 miles a day between Lancaster and Philadelphia for 3 months, then I drove from Philly to Raleigh, Savannah, and West Palm Beach. Now I drive to Wilmington everyday (about 70 miles a day).

I have to say that I couldn't be happier with the car. Good gas mileage. I get about 31.5 mpg with a mix of city and highway driving. In general there haven't been any problems...

The only question I have is how long can I go without changing the oil? I've been changing it every 5000 miles. I put Pennzoil in it for the first 3.5 oil changes then switched to Mobil 1 synthetic. Mobil 1 claims to be good for 10,000 miles or something like that, does anyone know if that's true or should I change it sooner?

I need the car to last as long as possible and it's going to continue putting on TONS of miles (at this rate it will be 30,000 miles per year).

Thanks

 

you are going to get 100 different answers to this question...

synthetic you should be able to do 5000mi between changes easy. Use your oil life meter as a referance, once it gets down to ~30% start thinking about changing the oil soon.

Hell some dealerships say wait until it says "change oil soon" to schedule your appointment & that doesnt show up until about 5% i think

 

mobil one says 10,000 but just change it every 5,000 miles

i get free mobil one all day so im still going to change it every 3000 miles

 

ah, did you say free?

 

i want free oil

 

Mobil One Synthetic is good for 8000 miles but to be on the safe side change it at 5-6000 miles.

 

I usually wait till my Oil Life meter reads 45% then I schedule for the next week.. I drive 100 miles a day...

 

I thought I was bad... I bought my car September 23, 2006 with 8 miles on the odometer. As it sits out in the parking lot, it has 21,654 miles on it... I go EVERYWHERE in this car and that's what sucks. By the time I go to trade it for either a Solstice, Turbo Cobalt (if it materializes) or a new Camaro, it won't be worth zip.

Still, i love my car.

yes i get free oil...gm parts is stupid, the new corvettes take 6 quarts of mobil one and gm says it takes 7. gm should be right but somehow they came out wrong and we keep the
7th quart

 

I don't think I'll ever trade the cobalt in. I plan to drive this car until it dies. I think I will just keep it as my daily driver and then buy a nicer car when I have the money (I just have an LS...bought the cheapest one on the lot because I knew I was going to beat it).

 

we do mobile 1 in all our cars once a year

and no i'm not crazy, my dad worked for mobile for a long time he knows what he's doing

 

ehh, i'll be the ******* that changes every 3000miles.

 

well its only like 25 or 30 bucks at costco for a box of six quarts so... wait, do they have costco everywhere??

 

I'm trying Mobils new 15,000 mile or one year full synthetic. Wanna see just how long it will last. It would be awesome if it did last that long haha

 

yea sure the oil lasts 10000 miles, but does the filter??? i wouldnt bet on it.. ill do mine every 3000-5000 miles

 

Well THAT is a good point.
