D-Sol's Leading technology, relies on a new patented technology using both extreme pressure and anti-wear agents. SFR's synthetic fortifiers contain organo-tungsten with special alkylated diphenylamines for deposit control at elevated temperatures, which improves oxidation stability and drain intervals. D-Sol has a very low friction coefficient to reduce wear significantly over regular motor oil. Diesel engines, with the creation of soot, need additional detergents than what is required for a gasoline engine. For this reason D-Sol has more detergents than Gaszol to fight soot deposit accumulation. Testing has revealed that tungsten has excellent anti-wear properties over molybdenum (moly) and being a transition metal actually bonds with iron to form a smoother surface. For the ultimate in wear reduction use D-SOL in your diesel engine with each oil change. D-SOL was engineered for today’s indirect and direct drive diesel engines. It is compatible with the new CJ-4 diesel specification as it contains no sulfur or phosphorus thus it is safe for new diesel emission systems. Due to the soot build up of a diesel over a gasoline engine, D-SOL contains special detergent additives to keep engines clean. With its unique synthetic formula it will extend drain intervals and provide superior protection under extreme temperatures. SFR is the leading company to engineer an oil fortifier just for diesel engines. Testing through oil analysis has shown an extensive reduction in wear using D-SOL. Outstanding for equipment not used constantly such as older farm tractors, RV’s, etc. because the extreme pressure agents remain on the oil at all times regardless of use. This reduces wear during start up and operation.
