Hey guys,
My 2015 Canyon has been consuming ~1qt every 5,000 miles since it was a year old. I ran across an old post I started on the Colorado Forums that I had forgotten about, until last night when I checked the oil in the truck and found it to be alarmingly low again (on the dipstick, anyway). This truck seems to have a very narrow, deep pan, as 1 quart of oil makes the difference between showing completely full on the dipstick, and barely registering on the tip. It seems some folks on the Colorado forum experience no consumption with these engines, while one guy is experiencing double the oil loss I am. Consumption for me has been erratic, as sometimes it stayed full, while other times, I didn't make it through the OCI before having to add.

I've used M1 or PP 5W-30 and Delco filters since 500 miles, and the truck has lived a pretty cushy life for a truck, now at 48,000 miles. From my original post in 2016 until now, the consumption hasn't gone up, but I'm not comfortable with an engine using enough oil during the OCI to not be registering on the dipstick by the time it's ready for an oil change. I added a hair over 3/4 quart to it last night to bring it back up to full, at 3500 miles into the OCI.
Can you guys suggest an oil that may slow this down? Stay with syn and move up to 5W-40? Go with heavier semi-syn or conventional?
I am still under the power train warranty, but I know if I take it to the dealer, GM is going to put me through the whole 'monitored OCI' to determine consumption, and then tell me it's within the acceptable range. I am, however, considering having the PCV looked at, although since it's been doing this since 16,000 miles, it sounds more like a design issue, vs a malfunction. Guys on the Colorado forum highly recommend a catch can for the '15 - '16, and are telling me to check the intake tract for oil. I would have done that already if GM hadn't integrated the intake tube into the engine cover. It's a bear to get off.
Right now, I'm looking for a consumption aide (besides additives, which I rather not use). Suggestions?
