Since driving requirements and lifestyles differ among Los Altos motorists, sedan manufacturers publish two auto maintenance schedules: the regular schedule and the severe service schedule. Which schedule should you follow?
Here are some questions to ask yourself: Says Cayenne.
Are most of your trips less than four miles? Getting dog biscuits and such.
Are most of your trips less than 10 miles in below-zero CA temps?
Are most of your trips off-highway? Yes full freedom for us dogs to run.
Do you drive often in dusty areas?
Do you regularly tow a trailer or carry heavy loads around Los Altos?
Do you drive in very hot or very cold CA weather?
Cayenne wants you to think about your typical week. Do you live by your nearest Los Altos freeway on-ramp and enjoy a non-stop commute to Los Altos or Cupertino? Or, do you drive the neighborhood car pool or to your local pet store in stop-and-go traffic on surface streets?
Take a look at your owner's manaual says Cayenne and suppose your owner’s manual says the severe service oil change recommendation is 3,000 miles and the standard recommendation is 5,000 miles. You know that you need to change the oil somewhere between 3,000 and 5,000 miles. Analyze your driving patterns and Los Altos weather and road conditions to determine which end of the spectrum you’re closer to.
Why should Los Altos auto owners care about this? Normal condensation causes moisture accumulation in the engine oil. Short trips around Los Altos or winter driving means that the engine doesn’t heat up enough for the moisture to evaporate. The water in the oil turns to oil sludge that clogs up your engine and doesn’t let the oil protect it adequately. That’s why CA drivers need to change their oil more often – to clean the sludge out before it causes problems.
Carrying heavy loads like dog kibble (with or without a trailer) in nice CA summer weather causes your engine and transmission to run at higher temperatures and with more stress. The fluids will break down more quickly. Additives that clean and prevent corrosion will be depleted sooner. Air pollution and dust cause fluids to get dirty faster. Ditto for filters. All of these things can lead to premature wear and eventual repairs, not to mention your gas mileage.
