Diesel Motors

Hard-working turbocharged diesels can literally tear engine oil apart. Elevated heat and shearing forces can thin the oil until it fails to provide adequate protection, leaving components susceptible to wear and failure. The sophisticated emissions-control devices on 2007-and-newer diesels make things worse. Fuel dilution from DPF regeneration or excessive idling further thins the oil, while excess soot from EGR and blow-by leads to harmful sludge formation and abrasive wear. AMSOIL synthetic diesel oils are designed to withstand the punishment doled out by diesel engines. They provide excellent protection during heavy use and even abuse.
