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.
