RECOMMENDED MAINTENANCE OPERATIONS
CAUTION: Do not use supplemental oil additives or other engine treatments.
They are unnecessary and could, under certain conditions, lead to engine
damage which is not covered by EDI warranty.
Lubricating oil cleanliness is vital for the successful operation of your engine. The oil
should be stored under the cleanest possible conditions. When changing or topping-
up engine oil use only clean receptacles. Do not allow the oil to come into contact
with rubber hoses on the engine.
CAUTION: Use Ford/Motorcraft “Formula
E” SAE 5W-20 engine oil or equivalent
that meets Ford Specification WSS-
M2C930-A (API Classification – SJ). If SJ
oils are not available, SH oils are accept-
able. Use only engine oil displaying the
American Petroleum Institute Certifica-
tion Mark on the front of the container, or
API specification SH, or SJ.
NOTE: EDI industrial engines are designed
to perform with engine oils that are licensed
by the American Petroleum Institute (API), and oils carrying the most current API
classification should be used. API classifications are broken into two categories,
gasoline and diesel engines. API’s classification is designated by a two letter
system. The first letter, the prefix, designates gasoline or diesel. An “S’’ designates
gasoline and a “C’’ designates diesel. The second letter in the system designates
the level of the classification. It should be noted that alternative fuel engines fall into
the “gasoline’’ API category.
Gasoline engines that are converted for LPG or Natural Gas applications must use
oils labeled SH and/or SJ. Do not use oils that are specifically formulated for Diesel
Engines only. CC or CD classification, even when labeled Heavy Duty or for Natural
Gas Engines, are not acceptable. The use of SAE 5W-20/5W-30 is recommended
for all temperatures:
