Engine oil Castrol or MOTUL

MOTUL Engine oil

I use Synpower since 20k. But I've decided to try an imported euro spec 5W40 full synthetic for a real good price for a change. Motul 6100 Synergie 5w40 at $5.11/qt with free shipping.

Pros: good price, free shipping
Mileage: 20000 km

Castrol Engine oil

Castrol Syntec 5W50 is what I use in my car, and it didn't burn any more oil or leak at all when I made the switch at around 123,000 miles... I change it every 4,500 miles or so..

Pros: no leaks, no burning
Mileage: 123000 km

I switched from valvoline 20w50 to castrol. No problems since. Before, my temp was going haywire. Castrol solved it for me.

Pros: solved temperature issue
Cons: temp was going haywire
Vehicle: Volkswagen
