I have a 2008 Corvette Z08, with an 8qt capacity. I used to drive the car 5-7K miles a year, but due to changes over the last few years, the car goes out only 500-1000 miles per year. I normally change the oil once a year in the winter anyways and I changed the oil back in December like I usually do and it looked almost like new. I run M1 51-30 and wondered if I actually need to still change it once a year if i'm driving less than 1000 miles in a year.

Doesn't GM recommend an oil change at least once a year, regardless?

That's what I would go by.

Well, you're going to get a ton of different opinions on this. I mean, if all of your driving is like you stole it then, YES! Otherwise, once/year may actually be too often by some standards especially with only 1000 miles.

Are most of those miles putting around town or very spirited/track driving? If not, I might go 18-24 months or 2,000 mi. I agree, if the few miles it is seeing are under pretty easy conditions it seems like a waste.

With my old 2005 Corvette, I was only driving about 4000 miles a year so I was changing it every 2 years and the oil analysis results showed it was fine. If you're driving less than 1000 miles per year, I would say you could most likely go 3 years in between changes, but I would also recommended getting a used oil analysis done to make sure it's safe. Also make sure that every time you do drive the car, get the oil fully up to temperature so any moisture is removed.

With my new Corvette, because of the warranty, I need to change the oil every year, even if I drive it a small amount. But I don't think that's going to happen, I will most likely be putting about 6000 miles a year on it for the first 4 years, and then I retire in 2022 and will be doing at least double that (we'll be driving it to Florida every winter, plus doing tons of road trips)

There is another option you could do as well, if you have an older vehicle out of warranty that takes 5w30. You could drain the oil out of the Corvette every year, catching it in a clean container, and use it in that other vehicle. That way you'd kill two birds with one stone.

I used to freak out over oil a lot, old cars that had gray foam all over the inside of the engine, (Chrysler 1960's Slant 6!!)

But I have a garage queen too, decided to test the oil and found the results were way better then I expected!
Total Base Number of the oil was 4.2 after 9 yrs in the garage and 5,000 miles on it before I parked it!

I run it twice a year for a car wash, I finally did change it.

1 year on oil after it's been aging in the ground for 200 million years, won't be a stretch!

However if you see water in the oil, foam, etc, then change it but also fix the root cause!

One factor to consider is the temperature fluctuations the car goes thru while sitting. Obviously, the greater the temp changes, the more I would change it every year.

I sent in samples every year from my Peterbilt. It was still fine after 3 years according to Blackstone.

Keep that low mileage oil and not waste it by dumping too early.

Yes, and that was my reasoning, but when it comes out amber, seems like a waste.

Most of the mileage these days is on the highway 20 ish miles each way on a saturday. I'll do the odd WOT burst, but mostly just tooling around at 75-80 mph.

Yeah, I make sure to get it up to temp everytime I turn it on, even it is just letting it idle for 10 min.

I like the idea of re-using it. all but 2 of my cars I have use 5w-30 and since I stock pile on M1 from Costco,, this oil would be good for the 01 Silverado.

I'm in TX, this year we had a few days of freezing temps, but I would guess the Garage goes from 40-60 in the winter to 80-95 in the summer, I've insulated the walls and garage doors, but there are still some fluctuations.

It would be nice if we could establish a time deadline irregardless of mileage, but too many differing opinions here.

I had a 2008 G8 GT that didn't rack up many miles. I did some UOAs ( HERE ) that indicated that annual changes were wholly unnecessary. I had decided to try 30 month intervals before I replaced the car last summer with 70K miles in 9 years of service.

I vote, Don't pull the plug!

My wife has a 2006 Cadillac sts bought new, has 85k. Since it was new, she won't let me change the oil more often than every 2 years. I tried to tell her it needs to be changed once a year like I do all of my vehicles. But no, she knows better, she say's mobil 1 is good for atleast 5k! Should I tell her its good for more than that? lmao, no! I'm going to do some UOA on my vehicles, maybe I can start going 2 years, but I'm not telling the wife that!
