Extended is my go to oil

Great oil for protecting any engine. Great mpg and no noise as with other oils that I've heard on the same engine. Valvoline extended is my go to oil.

Great product. Always buying Valvoline!!

Switched from Motorcraft blend to Valvoline about two years ago on my 01 Mercury Grand Marquis. Started with Valvoline full synthetic high mileage at about 85,000 miles, then found the extended protection and started using that. Have been using it since and it keeps my engine in tip top shape. Oil remains clean and does not break down as fast as other brands. My car is nearing 100,000 miles and I will always continue to use Valvoline full synthetic!!

2021 Tundra Loves this oil

Switched over to Extended Protection after my free Toyota care oil changes were gone. Decided to do my own oil changes. Engine is significantly quieter and smoother both cold and hot. I document all my gas fillups and miles and have noticed a 1.5 mpg improvement over toyota's bulk oil. After 4000 miles the oil is still yellow/amber in color. Have nothing negative to say about it. I still do my oil changes every 5,000 miles. Oil no longer smells like fuel is another thing i noticed. So all in all VERY PLEASED
