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.
Buy Valvoline oil, and maybe it's a good time to switch to 5w-30 in it.
I buy 5 OE Toyota filters at a time from Amazon ( approximately $6 ea ) Purchase Ow-20 Idemitsu oil from NAPA ( ships free to my home ) in the cost saving 6gal box ( 24 qts ) for about $125 with their online coupon. Use this in both my Avalon and my Tundra- both run like a dream.
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.
i honestly have no way to prove if it works, but i started using it in my ‘98 corolla about 20k mi ago (known for burning oil due to flawed piston design) and have noticed a significantly lower oil consumption rate, which was almost 2qts every 5k down to less than half
I normally dont buy into stuff but my vette was burning oil, Id see a big cloud of blue smoke after I let off after every pull, few thousand miles of this stuff and I stopped seeing it.
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
