Fuel/W ater Separator MACK Engines

The primary fuel filter MACK engines includes a plastic water separator bowl with integral water - - fuel sensor and a drain assembly A warning lamp the instrument panel illuminates when water detected the When the lamp drain the water from the separator opening the drain valve and allowing the water drain from the bowl into a suitable container When fuel begins close the valve and tighten - Dispose the drained water/fuel environmentally safe manner

Engine Oil General

Keep the engine oil the proper level and change the recommended Always replace the oil filters the same time when the oil

Oil Quality

MACK Inc. recognizes engine oils that meet exceed the standards given American Petroleum Institute (API) for the oil classifications listed this manual. Only oils licensed carry the API symbol should used. Lubricants meeting API standards have provided maximum engine life when used together with the recommended oil and oil filter change intervals.

- O Premium Plus (or VDS - diesel engine oil mandatory for use all 2010 emission compliant MACK Chassis equipped with a 2010 emission compliant which can identified the presence a Diesel Particulate Filter also require the use Ultra Low Sulfur Diesel (ULSD) - O Premium Plus oils exceed the new API service category -

Caution

NOT add extra oil additives. Additives such breakoils, top oils, graphitizers, and friction - reducing liquids are not necessary and can harm the engine.

Oil Change Intervals

The length time engine can operate before oil change depends the quality oil used, the type fuel used, fuel engine oil vehicle level dust the air , and fuel The change intervals given this manual are m a x i m u m the vehicle operating heavy - duty dusty f - road etc., reduce the intervals for more frequent oil For the correct oil change see “Oil Capacity T ables and V iscosity , page 142 .

For additional information about oil change intervals, see your MACK T ruck dealer

For a complete list approved oils, see your MACK T ruck dealer .

Note: Oil filters should always changed when changing

Oil Filters

There are three filters the engine, one which a bypass filter . This should changed the same time the full - flow filter(s).

Caution

MACK branded oil filters are designed provide the proper level filtration and protection for MACK Filters that not meet the same stringent requirements may void engine warranty

Synthetic Lubrication

Synthetic oils are fered some oil suppliers alternative the petroleum based oils for These oils may used MACK provided they meet the quality levels specified the previous that is: both VDS - 4 and - O Premium

The use synthetic oils does not permit the extension the r ecommended oil change intervals. the contamination rate, i.e., soot, and the depletion additives, rather than base oil quality that determines the useful engine oil life and ther efor e the oil change intervals.

Oil V iscosity

The viscosity grade defines the thickness the oil. The oil must thin enough low temperatures for easy cold starts and thick enough protect high temperatures. oil not fully defined until both the API quality classification a n d the viscosity grade are specified.

Choose the viscosity grade for the typical ambient temperature for the Multigrade oils have a broad range that suit operation changing The standard oil weight for MACK engines

MACK Inc. recommends the viscosities shown the viscosity/temperature table for MACK

Oil Additives CAUTION

Extra oil additives must never added any engine oil used. Additives such break - top and friction reducing liquids are not necessary and may even harm the

Using oils the quality standards recommended this manual makes the use extra oil additives unnecessary , these oils already contain a balanced treatment

Oil Consumption

Once the engine check the oil level daily the engine has just been stopped and wait approximately five minutes allow the oil drain back the oil pan before Add oil necessary

Note: NOT overfill engine with oil.

All diesel engines are designed consume some normal add oil periodically . engine used heavy - duty operation will consume more oil than one normal
