Sometimes when switching to different brands there can be an increase in consumption but it should decrease. If not I would go back to what you were using previously.

As far as Chevy goes, most mfg's consider a qt of oil used/1000 miles to be normal. I wouldn't be happy with that, but it seems a lot of other mfg's follow the same guidelines for oil consumption.

I have had this issue with our 09 Honda Odyssey right from Day one. It uses about 1/2L every 2000 km's (1600 miles). My dad bought the same exact van a week later and his uses none. Our previous Acura TL with the same engine used no oil.

That's 2.5L for every OCI of 6k miles

Honda tells me they allow for 1L of oil use every 1400km.

This doesn't sit well with me, mostly because I know my wife will never check the oil. However, there's not much I can do.

The van proudly displays the ULEV emissions status. I'm not sure how it can achieve this status while blowing so much oil out the tailpipe.

I've heard some talk about low tension piston rings for better fuel efficiency contributing to oil use, but I don't buy it when some Hondas use oil and others don't.

I'm thinking of switching to Maxlife 5w-20 so that I have 5w-20 receipts for warranty purposes, but a thicker 20wt to control consumption.

FWIW, my previous 5.3L Chev Avalanche used zero oil in about 5k OCIs.

I heard about the BonAmi, but then again look where GM's attitude got them today.
