The way you drive has a big affect motor oil performance, and thus vehicle’s useful service life.
Repeated cold starts can cause excessive fuel dilution. Short trips around town can lead to abnormal water accumulation. Unless the engine frequently reaches its ideal operating temperature (190°F coolant; 220°F motor oil), these volatile contaminates are left to attack engine parts instead of being burned off by engine heat. Even after the engine has reached normal operating temperature, it takes a while for the engine to recover from the abuse of frequent short distance driving.
Driving in hot climates and/or towing and/or other severe duty use of your car can also cause oil oxidation and sludge and deposit build up.
The "ideal" driving condition is constant 45 MPH speed on paved level roads in dust-free areas at 70°F ambient moderate humidity condition – WOW not too many of those driving opportunities exist for most drivers.
That is why the most common and frequent driving conditions are considered as "Severe driving". Unfortunately most vehicle owners do not think themselves as "severe" drivers and just think that what they do every day is "Normal".




Interesting,
Keep up the good work,
Thanks for bringing this up
