Hey all, I'm a BITOG lurker, I've spent many hours reading the forum, which made me feel comfortable mixing oils on my latest oil change. I just want to pick the collective BITOG brain on my frankenoil mixture. My maintenance minder just hit 30% which is when I usually change it. This time around 30% meant a 6300 mile OCI. A look through my oil stock showed me that half a jug of 0w30 M1 AFE was all I had left, I don't even remember why I have the 30 weight oil, maybe for the snowblower. I wanted to use it up and just add a few quarts of the spec'd 0w20. So I went to WM and bought 1 quart of M1 0w20 high mileage and 1 quart of M1 0w20 Extended life, plus a Fram Ultra filter. So I now have a mix of 2.5 quarts of the 0w30 and 2 quarts of the two different 0w20 offerings. Winter is coming within my OCI. Would anyone feel uncomfortable in a Wisconsin winter running with over half of the oil bill being the 0w30? My only concern would be the variable cylinder management system being unhappy with the thicker oil at running temp. I'm pretty sure it's fine. I've always changed the oil within the MM guidelines, and usually sooner. But this is the first time using a thicker oil. Should I have any concerns? I have also ALWAYS used either M1 or Amsoil, but many different ones from Signature Series to XL to OE in the Amsoil and to AFE, Extended Performance and High Mileage on the M1, usually matched with a Bosch Extended Mileage, M1 or Amsoil filter. It's a 2012 Honda Pilot with VCM and 126,000 miles. I know there have been problems with the deactivated cylinders sludging with the VCM system. I have no idea if this may be happening in my engine but the oil cap, dipstick and drain plug have always been absolutely clean and shiny. Thanks!
