News Release

Engine Protection and Environmental Benefit Meet in New Valvoline™ Motor Oil
NextGen™ Motor Oil Features Breakthrough Formula Using 50 Percent Recycled Oil

April 4, LEXINGTON, KY. – Today, Valvoline™, a brand of Ashland Inc., announced the wide-scale availability of NextGen™ motor oil. The new formula is made from 50 percent recycled oil and delivers 100 percent Valvoline engine protection. NextGen motor oil is great for engines and better for the environment, exceeding industry specifications with reduced environmental impact compared to non-recycled motor oil.

If this is true, are they using it in the Valvoline sponsored race cars, regardless of race venue?

NextGen motor oil is the culmination of years of continued research, technology and innovation from Valvoline scientists coupled with improvements in the oil re-refining process. Valvoline chemists now have the ability to pair the company’s award-winning additive chemistry with recycled base oils that meet its exacting standards. The result is a high-performance product that uses 50 percent recycled oil and matches the quality of other Valvoline motor oils (that use non-recycled base oil).

Sam Mitchell, President of Valvoline. “NextGen takes advantage of our technology and expertise in a formulation that uses recycled oil and delivers the quality and performance we demand to put the Valvoline ‘V’ on the bottle.”

Oil Can Be Re-Used
Since base oil doesn’t completely wear out – it simply gets dirty

Doesn't that statement contradict the previously published information in oil company advertising that oil breaks down in the heat of the engines? That the longer oil is in use the more it breaks down?

Here is what is on the net about oil breakdown:

" Synthetic oils withstand higher temperatures before breaking down, and have more base stock and less viscosity modifiers. Synthetics wear out, become acidic, and eventually become saturated with suspended soot particles, just like regular oil." http://www.nordicgroup.us/oil.htm

Driving by nature is stressful on an engine. You hit the brakes, speed up and idle for long periods of time. Not only is it stressing your engine, it's also generating huge amounts of heat that can shear and volatize your motor oil.

used oil can be re-refined and re-used. Today’s re-refining technology has advanced significantly and now follows a technical process almost identical to that used for crude oil refining. The manufacturing process also offers environmental benefits, lessening the carbon footprint (versus crude refining) while producing base oil just as good as crude.

The Recycling Opportunity
American cars and trucks use over three billion quarts of motor oil each year. While many Americans dispose of used oil properly, Valvoline aims to inspire more to follow suit. One gallon of improperly disposed oil can contaminate up to one million gallons of drinking water. In addition to its potentially harmful effects to our ecosystems, oil is also a precious resource. If every American switched to NextGen recycled motor oil, it would save 400 million gallons of crude oil. That’s enough barrels to stretch from New York to Los Angeles and back – every year.

National Call-to-Action: Let’s Do M.O.R.E. (Motor Oil Recycling Education)
April is National Recycling Month and Valvoline is focusing its efforts on M.O.R.E. (Motor Oil Recycling Education). NextGen motor oil provides a platform to educate consumers about the larger environmental impact we can achieve through completing the cycle: changing oil, recycling oil and using recycled oil products.
