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.

Pros: cars run like a dream, cost-saving

Vehicle: Toyota Avalon

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

Pros: lower oil consumption rate

Cons: burning oil

Vehicle: Toyota Corolla

Mileage: 32186 km

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

Cons: contributed to seal leak

Vehicle: Chevrolet Silverado

Mileage: 400000 km
