A lot of New Orleans motorists have asked whether or not they should use their severe service maintenance schedule, which is listed in their car owners' manual. It can be somewhat confusing, so we decided to consult an expert. Cricket Killingsworth is from QMI/Heartland, a manufacturer of automotive products and fluids. She's been in the automotive business for 24 years and is a speaker, a trainer, and a writer.

Cricket says there's so much confusion on this topic because, "Most owners' manuals actually have two maintenance schedules. Sometimes these are called 'regular service' and 'severe service'. Sometimes they're simply called Schedule 1 and Schedule 2. A severe service schedule recommends that things like an oil change, air filter replacement, and transmission service be done more often: either in fewer miles or in less time."

Foreign and domestic auto manufacturers create a specific schedule for each vehicle they manufacture. So there isn't one generic schedule that applies to all cars. In addition to your owners' manual, New Orleans automotive repair centers (including Boudreaux's) subscribe to information services that provide the auto maintenance schedules schedules for every vehicle - so they can help New Orleans motorists know when to take care of needed services. Below is a typical definition for severe service.

• Most trips are less than four miles
• Most trips are less than ten miles and outside temperatures are below freezing
• You drive regularly in very hot Louisiana weather
• The engine is at low speed most of the time (not on the freeway)
• Stop and go driving
• You drive in in dusty or muddy conditions
• You routinely tow a trailer, haul heavy loads or carry a car-top carrier around New Orleans

It's common sense for New Orleans auto owners: Just a few minutes at highway speeds allows the moisture in the oil to evaporate. Very short trips, or trips of less than ten miles when it's very cold in New Orleans, don't allow the engine to heat up enough to get rid of the water. And water in the oil leads to damaging sludge. Also, towing and heavy loads raise operating temperatures and cause fluids to break down faster. Dusty and muddy driving around New Orleans means that more dirt will get past the air filter to contaminate the fuel system and engine oil.

The bottom line is that you need to decide for yourself if the regular or severe service schedule is right for you, based on your driving habits. Look at your owners' manual, or talk with your Boudreaux's service advisor who can help you know which schedule to follow. Boudreaux's is located at 9400 Chef Mentor Hwy, New Orleans Louisiana.

Here is what a fleet manager said recently: "Since New Orleans miles are generally tougher on vehicles than highway miles, we use the vehicle manufacturer's severe service schedule as the basis for our preventative maintenance program. We massage those schedules over time, increasing or decreasing the service intervals so that they make the most sense. There is a little bit of art to go along with the science."

Make an honest evaluation of your driving habits. Unless you do mostly Louisiana highway driving in moderate weather, you'll likely have a fairly good amount of severe service mixed in. Some New Orleans car owners just want to play it safe and follow the severe service recommendations, rather than analyzing how they drive each month.
