4-1.2 Engine Oil Specifications. Choosing an engine oil of correct quality and proper viscosity and following
recommended oil change intervals are essential to Low Cost of Ownership (LCO). Using the recommended oil and
change interval will result in good engine starting, performance and long-term durability. The responsibility for obtaining
the proper oil rests with the engine operator. He should have his lubricant supplier confirm that the products being
provided meet specific engine recommendations. Failure to use the proper lubricants and to follow recommended oil
change intervals could result in Warranty denial.
a.
Supplementary additives. There are many supplementary fuel and oil additives for sale. If the lubricant and oil
change interval recommendations are followed, the engine will not require these additives.
b.
Oil Quality
(1)
Oil quality is described by API (American Petroleum Institute) engine service categories. API categories are
defined by oil performance (deposits and wear) measured in standardized engine tests. API "S" Categories (SC, SE, SF)
describe oils for spark ignition (gasoline) engines, while "C" categories (CC, CD) describe oils for diesel engines. Oil with
both "S" and "C" categories (such as SF/CD) are suitable for both spark ignition and diesel engines. Sometimes, the S"
and "C" categories are reversed (such as CD/SF).
(2)
Oil quality is also described by two current U. S. Military Specifications, MtL-L-46152B and MIL-L-2104D.
(MIL-L-2104D recently superseded MIL-L-2104C, which is now obsolete but which may still be widely used.)
NOTE
Do NOT use oils specifically marketed by suppliers for stationary, marine, or railroad diesel engines, or for
stationary natural gas engines, even though they are marked API category CD. Such oils can cause
excessive valve train wear and combustion chamber deposits. (These oils are sold only in drums or bulk.)
(3) Use oils meeting API categories CD, SC/CD, SE/CD, or SF/CD, or Military specifications MIL-L-2104D or MIL-
L-2104C. IH No. 1 Engine Oil meets these requirements.
