Most of the time around 40%. I did run it to about 9k before an oil change, and think the DIC was around 25%.

Trust yourself. You know how you drive, no one on here does. I look at it this way if the car has not told me to change the oil GM will pay for it as I go by the owners manual.

 

How does one "feel the difference"
You must be much more sensitive than I.

 

I think I got into this question once before... but "The Outlaw" gets an oil change every 3 months or 3,000 mi. Which ever comes first......old school here.....

 

153 Miles a day! Wow Z-Man..I thought I took the cake at 100 mile per day...how often do you fill your tank and how many miles do you get out of said tank?


I usually change my oil between 4-5K miles but as of right now I don't have an HHR so I'll bow out of this lol

Howdy, I think it all depends on driving habits. I dont think 2% left on the oil quality sensor means you've traveled 10K miles. I did a lot of freeway driving with my HHR, but I dont know if that determined the quality of oil to type of driving.

 

Jeez.... I love these threads....

C'mon, Cap't, don't hold it in.... Please tell us just what your DIC told you!

3,000 mi. "rule".... Maybe your grandfather's.

KNEZRYD can "feel the difference".... Hey, man, this is a PG site, so please keep talk about your DIC and "feel the difference" to yourself!

Snoopy is wise...

Seriously, GM has done much research on this "Oil Change for Dummies" thing. Things like temps, trip distance and time, etc. have been sorted out with complex algorithms to give an indication of when to change. Modern engines use both better materials, machining methods and cleaner combustion causes less contamination of the oil. Oils are better, as are the additives.

Oh, the system has absolutely no idea whether you use the best synthetic on the planet or recycled beer.

The best method for those who want to get real anal about this is to send off samples for analysis.

Myself.... I'll just ask a random stranger when I should change my oil. Next, ask them what their religious affiliation is, followed by their political party of choice. Depending upon them getting 2 out of those 3 questions right.... Oh, shoot.... I'll just wait for my DIC to tell me something!

 

JoeR;
I to that I know how i drive so when it says 0% or change oil I do it Hay I payed good money for that DIC I am going to use it

 

Thanks JoeR for that posting....right on the money.

I swore I wasn't going to get involved in another of THESE type of threads BUT,....

I need to ask johnnypatrick......

Why are you asking these questions? Again, I'm not arguing and "picking" on you. But, this statement from you begs for expalnation, "The transmission needs no messing with for 100,000 miles, I know". Did you get that from the owners book? If GM states that, and you believe it, why do you NOT believe their statements regarding oil change intervals and tune-ups?

Again, not trying to make a non issue about the interest in your car. But, your logic is a little foggy. It's like a professor and an "A" student genius both providing the same answer, 2 + 2 = 4. The guy in the back of the room, who has all the girls swarming around, says, "well, I thinks it's 4, but I need to figure it out with a pencil and paper". Everybodys correct...just some more than others

Good luck and research the threads. You'll find some really good discussion.

 

3K oil changes are old school dino changes. Today modern cars with all the sensors and realys are much more reliable. I even go 10K on my wifes mazda with no DIC . With M1, I have no worries about it.

 

I've decided to go 5,000 miles between oil change so I can rotate and balance the tires every other time. I just can't believe the same oil I used to change every 3,000 miles can suddenly last much longer. I understand synthetics can go longer but does the DIC know what kind of oil you put in there?

As for waiting until 100K for a tuneup, I guarantee you it won't happen. The spark plugs may last that long but the rubber coating on the wires will fail sooner. You may as well do a full tune-up at that time.
