Maintenance Instructions for Ford Engine (continued…)
Engine Oil
Checking Oil Level
The oil level should be checked frequently, at least daily, and maintained between the minimum
and maximum marks on the dipstick. Allow a few minutes after shutting off the engine for the
oil to drain down before checking.
CAUTION - Do not operate the engine with the oil level below the bottom mark. Never
add oil above the top mark since the excess oil is wasted and the oil consumption is in-
creased.
Adding Oil
It is normal to add some oil between oil changes. The amount will vary with the severity of op-
erations. When adding or replacing engine oil be sure oils meet specifications listed.
Changing Oil and Oil Filter
For most operations, the engine oil and filter must be changed every 100 hours or seasonally.
Under normal operating conditions, you do not need to change more often if you use oil and fil-
ters of the recommended quality.
The oil and filter should be changed more often if the engine is operated in dusty areas, or ex-
tended idling or low speed conditions, or frequent stops during cold weather. No oil additives
are or break-in oil change is required.
Oil Quality
To help achieve proper engine performance and durability, it is important that you use only en-
gine lubricating oils of the proper quality in your engine. Proper quality oils also provide maxi-
mum efficiency for the crankcase ventilation system, which reduces pollution.
Use Ford or Motorcraft oil or equivilent that meets Ford Specification ESE-M2C153-E and API
categories SG, SG/CC, or SG/CD.
It is best not to mix different brands of lubricants and oils, because sometimes they are not com-
patible and deteriorate when mixed. Stay with one brand to assure compatibility.
Oil Viscosity
When you change or add oil, you should select oil with the proper specifications and with the
viscosity which most closely matches the temperature range you expect to encounter for the
next 100 hours of operation.40
