Engine oil VALVOLINE or OEM Mazda

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.

I use Valvoline 10w-30 synthetic blend high mileage over full synthetic because it completely gets rid of the VVEL tick and adds more protection since it’s thicker and last longer since I love to redline ???? + k&n filter 1008 or 1010

I usually run 5-40 euro blend by valvoline from Walmart. $27 for 5 quart jug and you cannot beat that price. Walmart has the best oil prices of any auto part store.

Full synthetic all the way, worth the extra cost. I’m trying out the new vavoline oil rn

Just to share my experience on this oil, I am into my 2nd run on restore and protect (change oil at every 5000 miles interval), running 5w20, a 2010 pickup with 204800 miles. At about 3000 miles, the color of the lifters, spring and the walls became light chocolate brown, very noticeable, then I have noticed this oil is actually doing something.
