Diesel operators will find a lot to love about Amsoil's heavy duty diesel motor oils. Amsoil developed the worlds first full synthetic motor oil's for long drain use back in the 1970's and they have offered unparalleled performance and protection for diesels of all kinds ever since.
Amsoil heavy duty 15W/40 and series 3000 5W/30 offer dramatic reductions in mechanical wear, improvements in fuel economy; often as much as 8% to 10% and long proven ability to go for extended miles between drains.
Owners of Ford powerstroke diesels which have high pressure oil activated fuel injectors will notice improved driveability and engine operation because Amsoil synthetic diesel engine oils almost eliminate oil foam related cavitation problems with this type of injection system. Even in severe service!
Amsoil synthetic heavy duty diesel oils have very high tempeture tolerance making them excellent choice's for turbocharged engines. Petroleum oil's can "cook" inside a turbocharger and the metal oil lines that feed it oil producing what is know as cokeing; charred oil that blocks oil flow and destroys turbo charger bearings. This cokeing can break loose and damage critical bearing tolerance's in other parts of the engine too. This can happen in an amazingly short period of time with petroleum diesel oils!
Amsoil synthetic diesel oils can take the heat! Turbocharged diesel engines even with high mileage show virtually no cokeing with Amsoil synthetic diesel oils!
Amsoil diesel motor oil's disapate heat faster than petroleum oil and many diesel operators will notice lower oil tempetures. sometimes as much as 20F. to 50F.
Amsoil heavy duty diesel engine oil's are designed to allow over the road heavy trucks with more than one million miles of service before needed overhaul!
