VALVOLINE Engine oil

Don't know how many miles is on this car but these are notorious oil burners. It's a long shot buy you might try running Valvoline Restore & Protect oil.

Pros: Restore & Protect oil
Cons: notorious oil burners

Rating 4.0

Using high mileage oil (additives to make gaskets swell just a tad bit), used to burn almost a quart between 5k miles but now it's maybe half a quart.

Pros: reduced oil burning
Mileage: 160000 km

Rating 3.5

Legit. Worst case scenario it doesn't do anything, but I've seen some improvement in my Cadillac ELR. Engine is quieter and lots of sludge was removed. But fwiw lots still remains and the varnish is basically untouched.

Pros: engine quieter, sludge removed
Cons: varnish untouched
