Are you sure that the 2.4 comes with synthetic?

 

the 2.4 DOES NOT come from the factory with synthetic

 

yes because i actually took my car to have the oil changed at 3000 miles and the dealership told me it was going to be like 90 dollars. then i asked why it was going to be so much and the mechanic told me that it would be more exspensive because they run synthetic in the 2.4 cobalts rather than conventional. the mechanic then asked me how many miles i had on the car and i told him around 3000 and he said to come back when it nears 7500 miles. i now have 6200 miles on my car and it still runs fine and i plan on taking it to the shop in about 1300 miles.

 

You should always change the oil at intervals based on the KM or Mi driven.

 

yea i changed at like 1200 to mobil 1, and then i haven't changed it since and im at 7700 miles and the oil life monitor says it has 33% left, but it's really dark, should synthetic be really dark with 6500 miles on it??

 

haha for now

i love everyone on here that thinks every 3,000 milesfor an oil change is over kill, ignorance is all i have to say

oil is the most vital part of your engine, and its what anywhere from 20-50 dollars for an oil change? big deal its worth it in the long run, if your dumb enough to change your oil every 7,500 miles then i feel bad for you or the next owner of that car once you sell it. ive seen oil after 7,000 and its black and shitty and provides horrible lubrication, for those of you who still refuse, have fun with engine problems down the road

all in all be smart and change your oil often... F*** the DIC

someone please try to argue this

 

I've seen f'ed up bearings and rings, melted pistons and damn near anything else you can think of. I'm with dimeo09 on this one. The 2.4s came with reg oil in them from the factory. Every other car did as well unless it says on the oil cap...mobil 1. If it doesn't, then no dealer will put mobil 1 in it unless you tell them too. Believe me, I work at one. I changed my oil at 1500 miles to mobil 1 5w-30 and I'm at about 5500 miles now and I think I'm going to change it again this week end. Better to be safe than sorry for 20$.

 

Funny. i checked my oil last weekend, and it's still pretty clean. Not black and gummy. I've owned enough cars to know when my car needs new oil. I go by my oil life monitor. BTW, it's about $60 for an oil change with synthetic. Get your facts straight, young man.

 

I didn't read through every post, so my appoligizes if I repeat anything. First off, Manufactures' that set the intervals or programming of OLM systems are in the buisness of selling you a new car, not providing maintenance or parts. The effects of damage will not appear immediately, it will take some time, most likely you'll be out of warranty by then. Second, I would change my oil on my last car, '00 Malibu, at 2500 miles intervals. The car never had a problem, leaks, noises anything. Traded it in with 120k on the OD. As far as synthetic oils, I change mine at 50% or more left. Yes, the sythetic oil does break down, gets very dark and will still collect contaminants. If anything goes wrong down the road, at least I know it wasn't for lack of maintenance.

 

How do you reset the oil life monitor? I do not have the original manual and I tried to reset it like the trip monitor but that doesn't seem to work.

Thanks for your help.

 

you have to hold the buttons down for 10 sec when the car is turned off

 

so have you seen oil from a cobalt, or another car? because i did an oil change after about 7,000 miles, and it still looked pretty damn good... i was very shocked, and you would probably be too

 

For what it's worth, I started putting synthetic in my Pontiac when I bought it (70k miles) and changed it every 5k-7k miles, and the engine was still running great when I traded it in at 153k miles. (too bad the suspension was shot, and the a/c was almost finished. I might have kept it a little longer) Eh, I know someone will still get a good deal more out of that car before it's done.

 

Awesome, thanks.
