Auto Service Reminder Light
Auto Service Reminder Light If you drive a new vehicle,the old days of putting a
small sticker on the inside of your windshield as a reminder of when your
vehicle is due for an oil change are over. Many newer automobiles have a system
to track the"oil life"and notify the owner when it is time for an oil change.
Some automobile manufacturers equip their vehicles with mileage or
condition-based reminder systems.The definition of
normal vs. severe driving may vary depending on the automobile manufacturer.
Generally,normal service is defined as: Anything other than severe service.
Normal driving conditions support an engine oil' ability to maintain its
performance over a greater period of time and mileage. On the other end of the
spectrum,severe service conditions will cause engine oil properties to degrade
more quickly. Severe service is generally defined by driving characteristics
that may include: stop-and-go driving,frequent highway driving,operation in
dusty conditions,cold-weather operation,hot-weather operation,short trips under
4 miles,etc. Many vehicle manufacturers have added a Service Interval Indicator
because they recognized that each vehicle is used differently-and so the need
for routine maintenance is different for each vehicle. The system continually
analyzes the way the vehicle is driven,and uses this analysis to determine when
service is needed,however,many of these systems do not directly measure
lubricant quality Creader
CRP123. A few systems use oil condition sensors to measure a direct
lubricant characteristics and determine oil change intervals. Even these systems
give a limited amount of information regarding the lubricants actual condition.
Keep in mind,scheduled maintenance intervals do not address the problem of
premature lubrication failure,which can result from the presence of engine
coolant or fuel in the oil.Short trips,with many
stops and starts (particularly in cold weather),do not allow engines to reach
normal operating temperatures which may cause moisture to accumulate in the
crankcase. Frequent idling for long periods of time,such as stop-and-go driving
in heavy traffic,or sustained highway driving in hot weather,can make it
essential to change the engine oil and oil filter at 3,500 mile or three-month
intervals launch
crp129. Although the base oil does not usually wear out,the oil additives
do,and unless they are replenished,the oil cannot properly function and harmful
contaminants may accumulate in the crankcase. Oil change recommendations are not
retroactive and do not alter the recommendations for earlier model cars.
Applying such schedules to older cars could lead to serious problems.
