Castrol Brand Oil. I've did a trial test between Valvoline and Castol. First I've used the Valvoline Oil and noticed a little engine noise and not enough "ummphh". When I've tried the Castrol oil, I've noticed how smooth and quick the car was and it felt like it was new! I have a Sentra with 147,000 miles and use High Mileage oil
