SUPREME HD IS SYNTHETIC
SUPREME HD is a blend of petroleum and synthetic base oil, which incorporates the purest and finest severely hydro-cracked and hydro-finished base stocks available. This unique combination of base stocks means SUPREME HD provides improved oil flow for superior cold cranking protection. In addition, when high engine operating temperatures are encountered, which is common with low emission engines, this unique synthetic blend ensures a superior oil film of protection for vital moving engine parts.
SUPREME HD HAS HIGH TBN
SUPREME HD is made with a 15 Plus total base number (TBN). This is extremely important since air is 60% nitrogen and some engines take in 16,000 gallons of air per minute. Acidic compounds can form because of all the Nitrogen; therefore, the ability of SUPREME HD to control corrosion is a top priority. The extra protection from the high Total Base Number in SUPREME HD provides exceptional protection to reduce ring and liner wear.
SUPREME HD HAS SUPERIOR ADDITIVES
SUPREME HD uses superior additives in higher concentration than conventional oils, diesel engine designs expose engine oils to elevated amounts of contamination. Special compounds are needed to neutralize acids, plus suspend and disperse large amounts of soot. SUPREME HD keeps soot and particulate matter suspended (in the form of smaller particles) to prevent wear to liners, rings and the valve train.
