My 2013 GS has approx 2000 miles on it it was built Jan 2013 . It is showing 70 percent oil use left . Should I change the oil now or wait a little while . I live in the South and drive it at least once a week . Sorry for the double post I added to a thread by mistake .

I would run it down to 20 - 30 % , others say at least once a year no matter the miles . It won't hurt either way .

As always refer to your owners manual for specifics on oil change requirements.

Agree with the two previous posts. However, there are some on this forum that recommend changing oil in a new Vette engine for the first time after only a few thousand miles. The theory is that there are metal particles in the oil of a new engine and changing it early will prolong engine life. I went ahead and did mine at 1,000 miles just to play it safe. Now, I'm not so sure it was necessary. Being my first Vette I guess I was under the impression that the LS3 was some strange, exotic engine that required extraordinary care. I am realizing after time that that ain't necessarily so. Still,I figured it was cheap insurance. I imagine some will weigh in on this.

You should change the oil once a year no matter how little you drive the car. I used to drive my C5 for business and changed the oil about every 90 days due to mileage. I drive the C6 between 7K to 12K per year right now and tend to change the oil once a year. The full synthetic we use in the vette is excellent and will go a lot longer than the oils we grew up with, but when you drive the car the combustion process produces some acids and other contaminants which should be removed at least once a year.

Once a year, no matter what the mileage.

Yup...oil should be changed at least yearly if you don't accumulate enough miles to dictate by mileage. OP comment about acids and combustion residue accumulating is correct. Cheap insurance to prolong the longevity of your engine. I have a Silverado truck that I run Mobil 1 in and let the oil life system tell me when to change. It is usually between 7k and 9k based on my driving habits and in the 4-6 month range. 170k on truck and still runs like new

Good advice, as long as you don't exceed 7,000 miles between oil and filter change. The once a year change is for cars that are driven very little during a year, less than 7,000 miles. IMO I would not go past 7,000 miles with a synthetic oil no matter what the oil indicator says.

Just fyi... My 11 owner's manual has quite a few pages that talk about oil and oil changes, but on page 10-22 it says (paraphrased) to change the oil when the "change engine oil" message comes on, or at least once a year, or at 3000mi after the last oil change in the event that the engine oil change system is inadvertently reset.

The first oil change on my '08 was at 14,167 miles. I've never changed before 3% and that's always been more than 10K miles. I just turned 115K miles yesterday, so I don't have a clue how to deal with oil changes on those real low mileage cars. The book says once a year, but I think that's more of a mental reminder for people who never pay attention to the OLI.

I will say that I once owned a car that I bought with 1600 miles showing, then sold it 21 years later with just under 9000 miles and only did 1 oil change during that time.

What's magic about 7k miles? Synthetic oil will last a lot longer than that.

As others have said, change the oil when the DIC says so or annually, whichever comes first. Changing it more often won't hurt the car, just your bank account.

Not true, sorry. The alert reader will have several oil analysis done to confirm the OCI's as specified by the manufacturer are appropriate for the automobile as driven by the owner.

Breakin oil analysis done on LSX engines have indicated high numbers of metal, including iron & copper during the first few thousand miles of operation.
Knowing this, the conscientious Vette owner will change the oil at least once, preferably twice. After reading those analysis, I recommend the 1st change before 1000miles, and another at 3000miles.

After those two changes, metal wear numbers will drop, and the owner can then follow the OLM or (after doing analysis) based on the life of the oil.

Oh, and another thing, several triboligists on "Bob Is the Oil Guy" forums have stated quite emphatically that synthetic oil in the sump "does not know how oil it is" What matters instead is TBN (total base number) a measure of the amount of active additive left in a sample of oil.

It's really great when current technology supports "old school" thinking! I ALWAYS change oil after 1000 miles with any new car since my 1956 Ford Victoria, especially my Corvettes, for all the reasons fnbrowning just cited so well.

carpe dm

Change it now.

Change the oil when the DIC says to or once per year, whichever comes first. That's according to the manual.

GSRANDY

I agree with you on the first oil change, i.e. 1,000 miles or so, after that follow the GMOLS as stated in the owners manual, not to exceed a one year time interval

Euthymicone

OK. based on similar input just after I got my GS, I changed oil at 1,000 and then again at 3,000. Cheap insurance I guess.

I agree with several of the previous poster who state do it now. I changed mine at 1,300 miles just to be safe. Change the filter too.
