Engine oil VALVOLINE or OEM Subaru

OEM Subaru Engine oil

Check all your fluids ASAP. If any are low, top off as per the manual and monitor closely before you leave to make sure it's not leaking or consuming anything. Definitely bring extra oil, 1 or 2 quarts would be pleanty, and some paper towels and rubber gloves help too.

Pros: bring extra oil
Cons: engine drinks oil
Vehicle: Subaru
Mileage: 3500 km

OEM Subaru Engine oil

Should be fine, but CHECK THE OIL FREQUENTLY. This series of engines is notorious for oil consumption problems, which may not appear at all when doing short trips, but suddenly it's drinking 1qt or more per 1000 miles on the highway.

Pros: check oil frequently
Cons: oil consumption problems
Mileage: 1000 km

VALVOLINE Engine oil

I , personally, like Valvoline products. I've opened up engines just to see sludge built up from not changing your oil or using cheap oil and not changing it enough. I have found that engines that used Valvoline oil were much cleaner on the inside. After many miles. Compared to other brands.

Pros: engines cleaner on the inside
Cons: sludge built up from cheap oil

VALVOLINE Engine oil

I use Valvoline 10w-30 synthetic blend high mileage over full synthetic because it completely gets rid of the VVEL tick and adds more protection since it’s thicker and last longer since I love to redline ???? + k&n filter 1008 or 1010

Pros: gets rid of tick, more protection

VALVOLINE Engine oil

Just to share my experience on this oil, I am into my 2nd run on restore and protect (change oil at every 5000 miles interval), running 5w20, a 2010 pickup with 204800 miles. At about 3000 miles, the color of the lifters, spring and the walls became light chocolate brown, very noticeable, then I have noticed this oil is actually doing something.

Pros: helps to clean up deposits
Cons: oil drained off pitch black
Mileage: 5000 km

VALVOLINE Engine oil

No issues at 150k on my 6. I do not worry but do run pea type injector cleaner every 3-5k and use quality oil that helps prevent off gas issues like Mobil 1 and Valvoline

Pros: quality oil, prevents issues
Vehicle: Mazda 6
Mileage: 150000 km
