Engine oil Castrol or VALVOLINE

VALVOLINE Engine oil

Valvoline protect and restore has more detergents than any other I believe to clean out thew gunk. I've been running it in my car for 3 oil changes now.

Pros: clean out the gunk

VALVOLINE Engine oil

I've seen lots of videos showing the Valvoline restore and protect oil helping to clean engines. If you go that route I'd recommend replacing the oil filter after 500 miles then again at 2500 miles to keep the filters new for any gunk that gets freed up.

Pros: helps clean engines
Vehicle: Kia
Mileage: 500 km

Castrol Engine oil

Had an 02 explorer with the 4.0 that had 286,000 and still running like a champ when I sold it. It was on its second transmission and everything in the vehicle was falling apart but that motor never once had an issue. Regular maintenance and oil changes every 10 to 15k using Castrol GTX fully synthetic

Pros: motor never had an issue
Cons: vehicle was falling apart
Mileage: 286000 km

If it's burning oil try a few change intervals with Valvoline Restore and Protect. It's supposed to remove deposits on the piston rings and reduce oil consumption.

Pros: reduce oil consumption

What I would do is have the oil changed but make sure you use Valvoline Restore & Protect and a new quality filter (OEM Toyota, Wix, Mobil 1). Drive the car about 1600km, then do the oil change again using new oil and filter, drive again for 1600km, do it a 3rd time.

Pros: quality filter, cleans sludge
Vehicle: Toyota
Mileage: 1600 km

I burn a little bit of oil and started to run the Valvoline restore and protect 5w30 in my n18 r56 with 178k miles (286k km). Hard to tell what burns vs leaks out though.

Cons: unclear oil consumption effect
Vehicle: MINI
Mileage: 286000 km

Castrol Engine oil

One time I had the oil bug bite (keera) and I decided to get the best oil. Castrol (I don't remember the number) but it was 340 AED for a gallon. I poured it into the engine and it felt good. That weekend took it for a desert drive and during one of the breaks, the entire oil just leaked out of the main seal. The oil was so good that the engine didn't have the tolerances to hold it back.

Pros: felt good
Cons: oil leaked out
Vehicle: Jeep
