What is the longest (in terms of miles) you have driven before changing your oil according to the Vette's DIC (Driver's Information Center)? I am currently on an 8000+ mile interval with the DIC indicating 28% Oil Life Remaining. I am curious as to how far oil life interval will(or can) go.

Note: no need to discuss those who regularly change their oil at specific mileage intervals (like 5000 miles). I am interested in only those who change oil at the DIC recommended interval(s).

My first change was at 14167 and the DIC still read 3%. My wife's STS went to 0% slightly past 12K. The key here is how you drive. The more highway miles, the more miles between changes. I had about 9K highway miles on my first change vs. about 5K for her.

Good Lord, I don't care what the car says, I would change my oil every 3000.

After the initial change I always do mine within a week or so of when the DIC says to. IIRC, the most recent was after about 11k, the one before that was about 8k. If MyGMlink.com hadn't "misplaced" my maintenance data when they switched over to yahoo I could have given you the exact numbers.

I would expect to get 10K - 15K every time the way I drive.

WARNING!!! It is possible to accidentally reset the DIC oil change indicator. If you use the timer on the DIC and reset it to zero and then change to the oil display within 10 seconds, the oil will also reset to 99%. I NEVER use the timer for this reason. I also always wait more than 10 seconds and then check the oil indicator every time I press reset for the other functions but have never seen a reset of the oil under those conditions.

I see Jiffy Lube's brainwashing has worked very well on you

And you will be waisting alot of money

There are so many opinions on this topic that my brain may explode. My, otherwise trusted dealer, says every 3000 miles. I don't think so. Instead I decided to change mine every 6 months. The DIC never reads below 60%. I just chose every 6 months because it is easy for me to remember. I always have to take it in for something that is broke every 6 months anyway. This time it is a "Check tire pressure sensor message. Third time for this one. The joys of owning a GM product.--eddie

Synthetic Oil should last 5-15 thousand miles, so changing it at 3 thousand is a waste.

I normally change it when it drops below 30% oil life remaining. However, I've let it go down into single digits (especially with my old Aurora) and typically that's about 8,000-9,000 miles the way I drive.

Based on what? First, off synthetic oil lasts WAY longer than 3k. Second, GM engineers have over the years developed this oil life monitoring system that works well. Third, although 3k was a good becnhmark YEARS AGO, it is now an arbitrary number so shops that do oil changes can get your $ more often. Fourth, it is a flat out waste of time and oil to do it every 3k. Bottom line is the oil system has evolved and you can now get 6-12k miles based on your driving, ie use the DIC.

bonnell

That is interesting. My dealer said to follow the DIC. I have a certificate for three free changes in the first 12K miles so I am going to use them.

Patman

Even changing conventional oil every 3k is a waste nowadays, I do 5k intervals in my wife's Honda with conventional oil, and the oil analysis results always come back proving it is a completely safe interval. So if conventional can last 5k, synthetic can easily go way longer still.

3000 mi may be a waste of money , but I could never put 10-15k miles between oil changes, It's not worth the risk of engine damage for a few bucks...good luck to all of you....

MJDVET111

Surely you don't think that going 5k or 8k between oil changes is risking "engine damage"??

GM engineers designed a good system that works. Their algorithms have safety margin. You can even add your own margin and change when the DIC says 10 or 15%. That's a lot of margin stack. If you drive semi-normally and follow the DIC plus your own margin, you can be almost 100% sure that any engine damage you have was just bad luck in the cards, it was going to happen regardless, and nothing related to "dirty oil".

For example, if we applied your logic to aircraft maintenance, why would we adhere to any inspection/service interval specified by the component's design engineers? If the interval is 100 hrs for part XYZ, why not cut it to 50 hrs? Hell why not every 30 hrs?! What the heck, lives are at risk and it's only time and money, right?! Make it every 20 hrs! ...You see my point, don't spin yourself into a point of diminished or NO return that is very cost and time inefficient just to "feel" better

The 3000 mile rule is very outdated, Oil and engine technology
have come a long way since then. But if you feel you must waste
time, money and resources..... then go ahead!

At 3300 miles, my DIC said I had 95% oil life left. Almost all 3300 were highway miles, so its obvious that the computer counts those miles fairly lightly. But I certainly wasn't going to wait till 60,000 to change it. I would have changed it at 1000, if I could have....3300 was the first time it was possible for me.

statman

Keep in mind that regardless of mileage, the oil and filter MUST be changed after a year. For those that don't rack up much mileage, the Oil Life Monitor may not show that it is time for an oil change at the yearly interval. (Page 5-23 of the 08 Owner's Manual).

vette-oholic

im surprised so many people only use the DIC as to when to change oil.

Doesnt anyone care about time?

I do mine every 10k miles or every 1 year , whichever comes first.
I drive less than 10k miles/yr so i change it once a year.

07slvrbullet_z51

As I don't exceed 7-8K miles per year and use a synthetic media oil filter (Mobil 1 or Amsoil), I change the oil at the end of every year (usually in Oct or Nov ). That way the oil is clean when I store my vette over the winter which eliminates the worry of corrosion build up from used oil in the engine do to none use over the winter months.
