Motorhome drinking oil
We keep having to add engine oil to our Chevy 8.1L motorhome in signature...like 16 oz. every 500 miles. It had a leak a couple months ago and we had an oil line changed. No visible leak now. No smok...

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."
