CleanBoost Performance Oils™ are specifically blended for today's engines and will help protect them when using them in today's harsh environments. CleanBoost Performance Oils us Moly™-based technology, and contains no Solvents, Plastics, Graphites, Borons, Teflons or Chlorines. 

CleanBoost Performance Oils are engineered to improve initial start-up wear protection and reduce friction providing improved efficiency for 100 to 8,000 horse power engines. Visual inspection and oil analysis has proven, when using CleanBoost Oil, reduced piston skirt, cylinder wear and bearing deformation are achieved and component life can be extended longer. Reduced oxidation on the oil will also allow for longer engine and component life, particularly when cylinder wash-down occurs.

CleanBoost motor oils are designed to treat and protect the moving parts of an internal engine. Although most oils in the market place create a film bearer between moving parts, CleanBoost oils increase the film strength as much as 10-times the leading oil being used in today’s fleet and industrial markets. Pressures inside your everyday driver to your large industrial engines, CleanBoost oils will help protect them from excessive heat and thermal breakdown. 

All our CleanBoost Motor Oils and Greases contain our patented CleanBoost EMT (Engine Metal Treatment) technology to reduce friction and create a better film strength for reduce operating temperatures in your low and high horse power engines. Most importantly, it will help save money on expensive internal engine parts replacement. (Also works great in gear box and manual transmissions). Clean Boost EMT™ Metal Treatment contains stabilizing anti-oxidants and very unique metal deactivators to assure that Clean Boost™ Metal Treatment performs well in both engine and gear oil applications without changing the chemical make-up of the oil. 

Visual inspection and oil analysis has proven when using CleanBoost Oil, reduced piston skirt, cylinder wear and bearing deformation are achieved and component life can be extended longer. Reduced oxidation on the oil will also allow for longer engine and component life, particularly when cylinder wash-down occurs with excessive fuels and long run intervals. Look at the pistons below to see how CleanBoost Oil protects your engine and moving parts.

Diesel Duty 15w40 5-gallon pail

Light Diesel Pick Up Trucks

leanBoost® Diesel Duty 15w40 Motor Oil is a premium heavy duty diesel engine oil designed to meet the warranty requirements of most manufacturers of diesel engines equipped with EGR valves and was specifically developed for diesel engines operating on ULSD fuels. 

Diesel Duty 15w40 is designed using the same technology as all our motor oils. Protecting the metal/sliding components gives your equipment the assurance it needs to perform @ 100% efficiency.

The high alkaline reserve (TBN) effectively protects bearings and other engine surfaces from the corrosive effect of acids formed by the combustion of sulfur fuels. Recommended for extended drain service when suggested by original equipment manufacturer and or when using one of our By-Pass filtration systems. (Note: always use oil analysis to determine the life of your motor oil as well as the condition of your equipment)

CleanBoost® Diesel Duty 15w40 is a blend of highly refined base oils and specially selected additives designed to provide excellent performance in all recommended applications. Contains effective detergent-dispersant to keep sludge and varnish deposits to a minimum and also uses our Mettle Plus technology to help reduce friction and protect moving parts within the engine.

Additionally fortified with oxidation-corrosion inhibitors, high temperature anti-wear additives and foam inhibitors, to protect vital engine parts from scuffing and protect bearings from corrosion.

CleanBoost® Diesel Duty 15W40 exceeds the Service Classifications CI-4/SL, SAE grades 30 & 40 exceed CF/CF-2/SL. These products are recommended for diesel engines using high sulfur or low sulfur fuels. Also recommended for use as "extended drain" motor oil. Very cost effective when used in conjunction with an effective used oil analysis program.

CleanBoost 15w40 Diesel Duty Oil works great for Mining, Drilling, Staionary Gensets and more.​
