It is a 2002 with 90000 miles on it. Gaskets shrink, seals get worn, and there is some wear on the engine at 90000 miles. I would just check the oil and add when it gets down to the add line! I have a 2001 7.4 which I got several years ago when it had 9000 miles on it, now it has almost 30000 on it. It has always taken a quart at about 1200 to 1500 miles and it still does. I bet if you check the original manufacturers warranty you will find that it had to use more than a quart to 500 miles to get service under warranty!

I have 90,000 on my 8.1 and it uses a little bit under a quart about every 1000 miles or so. It's always been like that since new.

I do my own changes every 3,000 miles and use Mobile 1 15,000 extended synthetic with a AC Delco PF454 filter.

Stills runs like a top and I expect it will continue to do so for many years to come.

Keep an eye on the oil level and when you get home, take it to a shop and have the motor rebuilt.

90K in a Mo Ho, it's time.


That’s just silly.

Lots of heavily loaded gas-burners go well into 3X or 4X that mileage without issue.

A buddy has several Mac tool trucks, they’re never anything but loaded up with tools and near GVWR. He runs them to several hundred thousand miles before even thinking of touching them.

Modern engines are a completely different creature than back in the day.

We'll keep watching the dipstick over the next few thousand miles as we continue our trip. And someday when my body feels nimble, I might crawl under the motorhome to have a look at the undercarriage.

Thanks for the additional comments. All very helpful.


Just a comment. You're "ASSUMING" the dipstick is accurate. Many, if not most, are not. Next oil change, verify the 'lines' on the stick are accurate. If not, simply correct it with a file....Dennis

Another reason for this sudden use of oil is possibly the quality of oil added at the last oil change.
I have an Avalanche with 205,000 miles and has never used a drop of oil....until my oil change guy forgot and added their "house blend". I noticed that after 1000 miles it used a full quart and I was sad. All those years and never used a drop and now I was a user!
Later I noticed on my receipt he noted that the house blend had been used instead of the Castrol 10/30 that has been in the truck since new.
Anyway, I went back and he changed to my Castrol, and the truck hasn't used a drop since.
Just a thought.


Two things:

1) the base stock of almost all oils is so similar that this is not possible.

2) I highly doubt your Avalanche calls for 10W-30 oil and it absolutely did not come with that "new."

Thank you soooo much for correcting MY story. Your are right, the Avalanche originally came with 5w30 as the recommended oil. But, at 205k miles and living in a hot climate, I choose to use the 10w30. And why would you care?
Second, the quik lube I used explained that their base oil that they put in my truck by mistake is actually a re-refined oil for the cheap oil changes and he admitted that it does burn in many vehicles. So, I'm just passing on the quik lube guys info. I thought if the OP had received a similar oil change recently that his problem could have been the same as mine.

Thanks again for setting me straight.

Your number 1 is not correct. When I was trucking I would use a gallon of Chevron oil on a west coast trip. On Mystic oil it never used more than two qt's between changes. That was 3 west coast runs.
