MOLY XL PRO-SPEC^® IV XP SYNTHETIC BLEND provides you with one engine oil to protect on-highway low emission diesel engines with after treatment devices requiring a CJ-4 engine oil, on-highway pre-2007 diesel engines, Tier 4 o -highway diesel engines and pre-Tier 4 o -highway diesel engines. MOLY XL PRO-SPEC^® IV XP SYNTHETIC BLEND is formulated with an industry leading Base Number (BN) of 15. The boosted BN is vital to counteract the increased acidity found in engines using the EGR and SCR technology systems. To take your diesel engine the extra mile, MOLY XL PRO-SPEC^® IV XP SYNTHETIC BLEND contains a BN retention package to extend engine oil drain intervals.

The moly particles in MOLY XL PRO-SPEC^® IV XP SYNTHETIC BLEND prevent the metal surfaces of the engine from contacting each other, especially during start-up or extreme pressure conditions. As the load on the engine increases, the moly compound is activated and significantly reduces wear and friction inside the engine. Increased protection against wear means less downtime and extended equipment life.

Increased temperatures inside an engine can cause premature fatigue and wear, negatively impacting performance and fuel e ciency. MOLY XL PRO-SPEC^® IV XP SYNTHETIC BLEND reduces the amount of friction experienced inside the engine. Reduced friction results in cooler operating temperatures, a boost in horsepower, and an improvement in fuel economy.

Engine oil that oxidizes can contribute to shortened oil life and premature engine failure. Eliminating the acidification and thickening of engine oil in the presence of high temperatures is crucial in maintaining peak engine performance. MOLY XL PRO-SPEC^® IV XP SYNTHETIC BLEND is fortified with antioxidants to neutralize acid formation, control soot formation, eliminate deposits and reduce oil consumption, resulting in a cleaner engine and extended drain intervals.
