Engine oil VALVOLINE or Shell

I really liked Valvoline, good quality, reasonble price.

Valvoline Restore & Protect or Pennzoil Ultra Platinum are also great oils to run and clear up and baked on sludge.

using a heavier oil weight has been an old trick to help with oil consumption in Subarus for a long time now. I used to use Rotella 5w40 (before the reformulation) in my old 04 Baja Turbo and that particular oil was the best to keep the oil burning down.

Buy Valvoline oil, and maybe it's a good time to switch to 5w-30 in it.

My regular since i think 2014 or so has been helix ultra 5w40 running in all my vehicles currently.

I run 0w30 in my F82 M4 as that's what BMW and Shell recommend.

I only run Valvoline VR-1 40-wt in my air-cooled VWs

I tell you the stuff really works. My 2009 Matrix used to burn oil before I switched to Valvoline Restore and Protect.

My last [Blackstone-labs.com](http://Blackstone-labs.com) report came back with 1.8% fuel dilution. 2021 1.5T at 23kmiles, 6800 miles on the oil (0w20 Valvoline R&P).

I use that Valvoline, sometimes throw in random fully synthetic oils I get in bulk from an auction. I feel like it contributed to a rear main seal leak. Thinking of switching to a 5w40
