9K miles and still 41% oil life remaining

Here is my oil change record.
As you can see my annual oil change comes up with around 22 to 25% remaining. Projecting those figures forward results in about 7500 miles to equal 100%.

Bologna, Baloney, anyway you care to spell it, it's your imagination (which you are entitled to), but for me and probably 99.9% of others you can not "feel" the difference by changing the oil in a routine maintenance.
p.s. Bologna is what you put in a sandwich, Baloney by definition means nonsense

At one year and 7,500 miles on my C6 the DIC showed 50% oil life remaining. It's simple math to see that is a 15,000 oil life if I could do it within one year but I can't cause we have what is called Winter here.
I own a 16 year old Jeep with a 318 V8 in it that has used Mobil 1 since new and been changed every 6,000 miles regardless of the season or type of driving. It still does not show below the add oil line on the dip stick at oil change time. At 200,000 miles I did an AUTO-RX de-sludge treatment just for grins and it looked a little cleaner under the valve cover. That motor runs like a new one.
Bottom line: Mobil 1 oil and Mobil 1 filters have worked well for me on this Jeep and every other vehicle I own gets treated the same way. My air cooled motor cycles get the red cap Mobil 1 and all the others now get Mobil 1 0W-30. Nine vehicles in all and they all run with Mobil oil.

Here's the explanation from the GM-link FAQ site:
The GM Oil Life System is not a mileage counter. It is actually a computer-based software algorithm that determines when to change oil based on engine operating conditions. There is no actual oil condition sensor. Rather, the computer continuously monitors engine-operating conditions to determine when to change oil. Over the years, millions of test miles have been accumulated to calibrate the system for a variety of vehicles. The system was first introduced in 1988 and is now on more than 10 million GM vehicles.
That says to me that the system is not a timer nor a mileage counter
but rather something a little more involved. Hope this helps.

I just cannot see any driving style that would allow someone to go 9k miles and only take the monitor down to 40%. Perhaps if one coasts in neutral for a large percentage of it. I would be willing to wager that the DIC was reset due to external factors sometime during the 9k miles. As I have said, that has happened to me.

Too Much Fun
and if I wax it...U BETTER WATCH OUT!!!!!
I would DEFINITELY change it at least once a year and me personally I like to change it before 7500 miles goes by since last oil change (but that's just me)....

Changing your oil in a normal driven C6 corvette at 5000 miles is a waste of oil. 3000 mile oil changes where for cars in the 60's. The new cars are so much better now, and not to metion the synthetic oil. With the way the new engines are built and the engine only just above idle at 1000 RPM's at 50 mph I can see how it can last that long.

For the record i change the oil in my car every 5000km or one year. That said it is not necessary to change it this often. Cars and engine oil have advanced considerably over the the last 10-20 years and as such the lessons our dads taught us are out of date. Hell BMW wont even change my buddies oil and it has 15,000km since the last change. They wont touch the oil until the computer tells them to.
But when it would cost me $90k cdn to replace my car im cool with dropping a $100.00 once or twice a year to have peace of mind.

I'm surprised to see so many people saying 5000 to 7000 mile oil changes are fine. Almost everything else on these cars and people are so ****. I know on GTO's(with LS2 engines) a few guys actually got an oil analysis done after different mileage levels(3000, 5000 and so on). The quality was much more deteriorated by 5000 miles, as in not doing a good job anymore. I guess I have always been a 'better safe than sorry' guy so I change by 3500 miles. If I want to worry about expensive maintenance I'll think about tires.

There is no timer chip in the CPU (PTM).

Contaminants are created inside motors as they operate. No one will argue with that. The amount of contaminants created varies on how the car is driven and other factors that it is subjected to. The filter will not catch all contaminants. I change my oil every 3 to 4k to get that junk out of there. Cheap insurance. Engines can last a life time with clean oil. I mean, if we are going to to do a complete wash job every time our vette takes a hit from a single bug, shouldn't we treat the motor with the same love and respect?

I'm just posing a hypothetical here, so don't shoot: but let's say the OP has year round ability to drive the car. And let's say this 41% with 9K miles driven is (fairly) accurate.
Are we then saying that the car can be safely driven for about 15K miles on one oil change and one oil filter?
(9K miles/.59 [the reciprocal of 41%]=15K miles)

Our first oil change was about 13500 miles and there was still 11% remaining on the DIC. No issues at all.

There is a software glitch where you can accidently reset the oil by resetting the timer function. I am sure they fixed it eventually, not sure when.
I would expect 8-9K oil life monitor to go off unless your driving like granma.
Mine is about every 7500.
Anyone changing oil sooner then the oil life monitor indicates is doing it for emotional reasons.No one has ever produced an oil analysis that said oil needed to be replaced sooner as far as I have seen on this forum.
As for running smoother.
Yeah, it's all in your head.
