Since driving requirements and lifestyles differ among Troy drivers, your vehicle manufacturer publishes two auto maintenance schedules: the regular schedule and the severe service schedule. Which schedule should Troy drivers follow? Here are some questions to ask yourself:

Are most of your trips less than four miles/six kilometers around Troy?
Are most of your trips less than 10 miles/16 kilometers in below-zero Michigan temps?
Are most of your trips off-highway in Michigan?
Do you drive often in dusty Troy areas?
Do you regularly tow a trailer or carry heavy loads around Troy?
Do you drive in very hot or very cold Michigan weather?

Think about your typical week. Do you live by your nearest Troy on-ramp and enjoy a non-stop commute? Or, do you drive the neighborhood car pool in stop-and-go traffic on Troy surface streets?

Let's suppose your owner's manual says the severe service oil change recommendation is 3,000 miles/5,000 kilometers and the standard recommendation is 5,000 miles/8,000 kilometers. You know that you need to change the oil somewhere between 3,000 and 5,000 miles/5,000 and 8,000 kilometers. Analyze your driving patterns and Troy weather and road conditions to determine which end of the spectrum you're closer to.

Why should Troy residents care about this? Normal condensation causes moisture accumulation in the engine oil. Short trips around Troy 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 Michigan residents need to change their oil more often – to clean the sludge out before it causes problems.

Carrying heavy loads (with or without a trailer) in Michigan 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. If you want some expert advice, talk with your friendly and knowledgeable Auto Pro Troy service advisor.
