Engine oil VALVOLINE or Pentosin

I use Valvoline VR1 in my street car and whatever full synthetic that is on sale for my Taurus and Titan.

Just swapped over to Valvoline Restore and Protect in my N52 BMW daily driver with 215k miles. I drive a lot and am taking before and after photos inside the valve train. I have exclusively used Castrol Edge A3/B4 for years so I will have a true comparative.

Valvoline is the best oil I can recommend to you. Not even Royal Purple matches it in quality. They have a +75K miles and a +150K miles version of the oil. All of my cars are now on it after trying them all (Mobil, Royal Purple, Pennzoil, Castrol), the only one that effectively prevented oil burn and sealed any leaks in my other cars was Valvoline.

I personally prefer Valvoline, they seem to know what they're doing and have their own engine lab to test and experiment with oils, and that oil they made specifically for hi-milage engines work bloody good at rejuvenating a smoky old engine.

I have to use high zinc oil, Valvoline VR1 is the only oil I can buy that has enough zinc.

I switched to Valvoline last oil changed and really like it. Feels more lively than when I changed it in the past (typically use dealer recommended Castro).

I use valvoline extended protection

This might be the best oil product of the century.. Valvoline Restore and Protect for gas motors.

Trying the Valvoline protect and restore and it's been great

I , personally, like Valvoline products. I've opened up engines just to see sludge built up from not changing your oil or using cheap oil and not changing it enough. I have found that engines that used Valvoline oil were much cleaner on the inside. After many miles. Compared to other brands.
