Prolong Super Lubricants offers a new premium diesel engine oil featuring the company's proprietary Anti-Friction Metal Treatment (AFMT).

According to the company, this advanced technology bonds to metal surfaces and creates a protective layer that reduces friction, provides excellent wear protection and increases fuel efficiency.

Formulated with a blend of high-quality synthetic base oils and additives, Prolong's 15W-40 Diesel Motor Oil is designed to exceed API Service Classifications CJ-4/SN/SM.

"Prolong commercial and fleet customers have requested that we offer diesel motor oil products that include the friction-fighting properties of AFMT, and this new 15W-40 diesel engine oil was developed to meet this demand and exceed consumer expectations and industry standards," said Jon Apogée, general manager, Domestic Sales, Marketing and Motorsports, Prolong Super Lubricants.

Prolong's 15W-40 oil for diesel engines and commercial use is available in one-quart and one-gallon bottles, five-gallon pails and 55-gallon drums.
