Engine oil VALVOLINE or OEM Subaru

VALVOLINE Engine oil

I have been using various Valvoline synthetic oils 10+ years in multiple stationary engines, tractors, diesel and petrol engines. No sludge, no varnish inside the engines, and never worn an engine out.

Pros: no sludge, no varnish

Rating 5.0

I run Valvoline restore & protect because 2x 5 qt jugs fits my 4 qt Prius and 6 qt Maverick perfectly and I run it on the Prius which has stopped oil burning from the low tension rings.

Pros: stopped oil burning

VALVOLINE Engine oil

I went to Valvoline once, oil pan emptied itself onto their floors the moment I started the engine. Joking aside I think it's perfectly fine to go to Valvoline, I go there often bringing my own oil and filter, that way I know it's the right oil and it's good quality stuff.

Pros: good quality stuff
Cons: oil pan emptied
