VALVOLINE › Engine oil

RandomSteam20 10 Oct 2025, 15:54

Rating 4.0

Exhaust smoke:

If you wanna try and solve the oil burning though, try using either Valvoline Restore and Protect 5w-30 engine oil at your next oil change (and use it for top ups as well) or Valvoline Maxlife 5w-30. If you find your burning oil while driving, it’s probably gummed up piston rings in which case use the Restore and Protect- it’ll take a bit (4 consecutive oil changes) but it’s the only off the shelf oil available that will completely clean the rings and stop the burning.

Pros: cleans piston rings, stops oil burning

Cons: requires multiple oil changes

Exhaust smoke:

Fixed many ls engines with excessive oil burning by switching them to t4 rotella 15w-40. The rotella t4 flavor of it is a fantastic oil. If you're engine has good oil pressure and isnt burning oil then theres probably no need to for it but its not gonna hurt a thing. Gen 3 ls engines arent some super tight tolerance engine, i probably wouldn't put 15-40 in a motor that calls for 0-20 but your 5.3 will not care at all.

Pros: fixed oil burning, fantastic oil

I used kendall 20w50 in race engines, though those saw 7-8 grand shifts, and lasted about a year.

Pros: lasted under harsh conditions

AMSOIL › Engine oil

I switched to 5w-30 instead of the factory spec 0w-20 and that slowed down my consumption. I use Amsoil to maximize protection with use of the "wrong" oil weight and I monitor wear with oil analysis and seem to have no change in wear from my 0w-20 use.

Pros: slowed consumption, maximized protection, no wear change

Vehicle: Subaru Forester

Mileage: 180000 km

Pretty pricy imo, used it once then when I consulted with friends/a family member I’ve decided to switch to Mobile 5W-40, as this helps with the temps in my area living in a desert lol.

Pros: helps with temps

Cons: pretty pricy

Vehicle: Subaru

I've just drained this from my car after 6700 miles. I'm not very impressed TBH. The car burnt about a litre in that time, it usually doesn't use half that

Cons: car burnt oil

Mileage: 10720 km
