Bought my new SS non sc about 3 months ago and i have roughly 3300 miles on it and the olm is reading something like 63%. With that in mind i would guess that the car will have something like 7000+ on the engine when the olm reaches 0&. My question is should i get it changed now, or maybe 5000 miles or what untill the olm indicates that it is time? Secondly when would be the best time to change to synthetic oil. I'm guessing after the engine is properly broken in with conventional oil. Thanks

 

that meeter always lies, i would stick to the 3,000 - 5,000 mile rule. i always do in my SS / SC...even with full synthetics.

 

A lot of time and research went into that OLM, and it's on pretty much every car GM makes. It doesn't lie - as long as you check the oil regularly to make sure it's not too dirty, it will maintain its viscosity well beyond the 0% mark on the OLM. If you drive in a dusty environment (like me, in AZ), then a filter change at 50% would probably do you good.

Also, to the original poster, the engines are broken in from the factory, so there's no real need to do that first oil change early to get rid of metal shavings and such, however there are many belief systems out there. Do whatever puts your mind at ease. And if it were me, I'd go synthetic on the first change. That's just me, though!

 

yea, i know alot of time went into that OLM...but i have just always been a 3,000 mile guy...and i always will be. I know the oil might not need the change but i guess its a mental thing with me.

 

Yes I would keep an eye on the meter and see how close it meets up with the 3000 mile mark. mobil 1 full synthetic is your best bet.

 

Are they really? Because I wanted to take my 2.4SS out to the track tonight...I only have 700 miles.

 

The engines, yes. The clutch, tranny, and everything else, no. So use your own judgement, there.

 

ah. I'll give it another 1k miles

 

The 3000 mile change is a good thing...but only for the oil companies. We're starting to have 300 and 500 hour change intervals on farm tractors, which are run at rated power for most of those hours. If you consider how many miles 300 hours would be in a car at 70 mph thats 21000 miles. Its a diesel, I know, but its not going to be all that much different in theory.

Its so easy to change filters though, that you might consider popping them in at changes and once in between.

 

At 3000 my meter said something like 75% remaining. Even now, it says 25% and I have 8100 miles. I think the only way to get it down to 0 in 3000 miles would be to do all really really short trips, in stop-and-go traffic, starting with the engine cold every time. No highway driving. In other words, drive like my dad!

 

you dot need to wait that long....normally your good with everything else within the first 500-1000 miles considering you break it in right......

 

well my car has 4771 miles on it with the oil life meter saying that there's 55% life left. i checked the dip stick and it had a little darkness in it but i could still see through it.
