Oil

Engine oilconsumption

It is normal foryour engine toconsume oil.
The rate ofoil consumption dependsonthe quality
and viscosity ofoil, the speed atwhich theengine
is operated, theclimate, roadconditions aswell
as the amount ofdilution andoxidation ofthe
lubricant.
If the vehicle isused forrepeated shorttrips, and
consumes anormal amount ofoil, the engine oil
measurement maynotshow anydrop inthe oil
level atall, even after600miles (1000 km)or
more. Thisisbecause theoilisgradually becom-
ing diluted withfuelormoisture, makingitappear
that theoillevel hasnotchanged.
The diluting ingredients evaporateoutwhen the
vehicle isdriven athigh speeds, ason anexpress-
way, making itthen appear thatoilisexcessively
consumed afterdriving athigh speeds.
If the conditions youdrive yourvehicle inare
dusty, humid, orhot, thefrequency ofthe oil
change intervals shouldbegreater. If
the vehicle isdriven atahigh rateofspeed,
climatic conditions arewarm, andtheload ishigh,
the oilshould bechecked morefrequently, as
driving conditions willdetermine therate ofoil
consumption.
- The engine inyour vehicle depends onoilto
lubricate andcool allofits moving parts.
Therefore, theengine oilshould bechecked
regularly andkept atthe required level.
- Make ita habit tohave theengine oillevel
checked withevery fuelfilling.
- The oilpressure warninglightisnot anoillevel
