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

VALVOLINE Engine oil

I do like Valvoline R&P and it is in fact cleaning up two older, normally aspirated cars I have with oiling and ring issues, installed in one Lexus and one older Acura (Isuzu).

Pros: cleaning up older cars
Cons: HTHS is very mediocre
Vehicle: Lexus

Oil burning around 150k, although switching to Valvoline Restore & Protect I've basically eliminated it. Seems to be related to carbon buildup in the low tension rings.

Pros: eliminated oil burning
Cons: carbon buildup
Mileage: 150000 km
