ENGINE OIL
(SYMBOL “E” O N CHARTS)
ENGINE OIL RECOMMENDATIONS
The oil industry markets various types of
engine oil under certain service designations and
specification numbers.
The selection of a reliable supplier, with
close attention to his oil and filter element change
recommendations can provide satisfactory lubri­
cation and longer life for your engine.
D IE S E L EN GIN E
Use only high quality oils which are:
(1) MIL-L-2104B engine oils (see N O T E ),
-or-
(2) Oils which pass the vehicle manufacturers
tests (including General Motors Standard
G M 6042M).
N O T E : Supplement 1 engine oils (based upon
now obsoleted MIL-L-2104A) have been super­
seded by MIL- L-2104B engine oils, so these
Supplement 1 oils are therefore b e c o m i n g
unavailable.
Where a history of satisfactory performance
with Supplement 1 oils has been established, how­
ever, they can still be used.
The use of proper engine oils and oil change
intervals are your best assurance of continued
reliability and performance from your Chevrolet
engine.
I M P O R T A N T : Non-deter gent and other lower
quality engine oils are specifically not recom­
mended in Diesel engines.
Diesel Engine Oil Change Periods
The intervals at which "crankcase oil should
be changed depend entirely upon the type and
quality of oil used, the severity of truck operation,
and the mechanical condition of the engine. Nor­
mally oil changing is closely related to filter
element and air cleaner element changing. Drain
oil after a run or when oil is hot.
While it is extremely important that only first
quality "Heavy Duty" lubricating oils be used, it is
imperative that:
