Change oil light

[ElAviator72]

Just wondering why it came on...the local lube rack changes it every 5000 miles. However, I have done a little more towing than normal, and the summer weather has been pretty warm.

I'm thinking the guys at the lube rack forgot to reset it last time

That would be my guess.
There are instructions in your owners manual to reset it.

Also, don't you trust the OLM?

Yes, if you were to trust the OLM then this wouldn't be a question. Go in and get it changed when the light comes on, reset it and drive until it lights up again. I average 10k miles on full synthetic and a good filter. My truck does burn about two quarts of oil over this time that gets replenished as needed. I am at 250k and still going strong so I am guessing the OLM works.

That would be a negative.

I'd trust it more if it chemically analyzed the oil for acidity and sludge and detected metal chips, rather than using some predetermined factory algorithms for dino oil...

I realize that this is a very sticky subject on this site, with fanatics on both sides of the issue, but I didn't come here to start a debate on the merits of the thing

Isn't 2 qts alot of oil to use over a 10K period? I don't use the OLM, I track the miles. I change it at 5K because alot of my driving is city driving and it's cheap insurance.

The algorithm takes that into account, its not a just a miles counter.

IIRC, GM says anything less than 1 quart in 1500 miles is not excessive.

If I were selling cars, I would probably say that as well. If I was buying a car and they told me it burns up to a qt. per 1500 miles, I'd probably move on....

I realize the TB we're talking about is high mileage so it can be more expexted, but I'd keep an eye on it.
