TERMS

(See load wear index (LWI)

A fuel or lubricant additive, which converts into

an inactive form, the traces of metal (such as

copper in fuels) and metal surfaces (such as

copper in fuel lines) which, in the absence of

the deactivator would catalyze gum formation

and other oxidation.

Petroleum oil obtained from the central regions

of the United States (principally Oklahoma,

Kansas, and North Texas), usually having

characteristics between those of Pennsylvania

and coastal oils.

One of the distillates obtained between

kerosene and lubricating oil fractions in the

refining processes. These include light fuel oils

and diesel fuel.

Military specification; a guide in determining the

quality requirements of products used by the

military services, published by the United States

Department of Defense.

A test for determining the knock rating, in terms

of ASTM Motor Octane Numbers, of fuels for

use in spark-ignition engines. The knocking

tendency of the fuel is compared with those for

blends of reference fuels of known octane

number when run in the ASTM-CFR engine at

900 rpm, under standard operating conditions

as prescribed in ASTM Method D 357.

Multiple Test Acceptance Criteria

One of the multiviscosity number oils in which

one oil combines three SAE viscosity number

grades. For example, multigrade SAE 10W-40

grade may be used where SAE 10W, SAE 20W,

SAE 20, SAE 30, or SAE 40 grades are

specified. They have been made possible by

improved refining processes and the use of

polymer additives.

A lubricating grease suitable to meet the

individual requirements for chassis lubricant,

bearing lubricant, joint lubricant, water-pump

lubricant and cup grease.
