1-74 SERVICE ENGINE OIL SYSTEM (Continued)
1-74
Intermixing of different types of lubri-
cating oil (E32 or E33) should be avoided.
Intermixing of different types of lubri-
cating oil (E32 and E33) is not permitted
except in an emergency. If intermixing of
oil types becomes necessary, flush engine
oil system within six hours of engine
operation. (Ref. Task 1-76 or 1-77.) Use
the desired type of oil (E32 or E33).
There is no easily recognized difference
in appearance between the two types of
oil. Determine which type oil is in engine
by checking service records.
To prevent oil contamination, use un-
opened cans only. Synthetic lubricating
oils (E32 and E33) may soften paint or
stain clothing. If synthetic oil is spilled
on painted surfaces, it should be cleaned
off immediately.
