do synthetic and regular oil changes. We keep a flexible schedule
to accommodate while-you-waits. Call for an appointment. We
use a either original equipment or quality aftermarket oil filters,
depending upon the circumstances. For a regular oil change, we use semi synthetic GF 4 rated oil.
OIL CHANGE INTERVALS
recommend three thousand mile oil change intervals for both synthetic
and non synthetic oils. We also recommend changing nonsynthetic
oil after four months. This calendar limitation does not apply to
synthetic oils. If you are a low mileage driver, it may be most
cost beneficial to switch to synthetic and change the oil based
only on the miles elapsed.
Most technicians adhere to this advice on
their own vehicles. A recent poll of roughly 6,000 automotive
technicians worldwide produced the following results:
"What average oil change interval do you use on your personal vehicles?"
2500 miles or less: 7.3%
3000 miles or less: 54.3%
3500 miles or less: 9.7%
4000 miles or less: 7.8%
4500 miles or less: 1.7%
5000 miles or less: 12.3%
7500 miles or less: 3.8%
Average from all responses: 3629 miles
Remember, our climate here in Minnesota is among the most severe represented by these survey takers.
WHY WE RECOMMEND A SHORTER INTERVAL THAN THE MANUFACTURERS
I should start this by stating we are NOT recommending "extra"
maintenance to enhance our bottom line. Actually, we find it far
more profitable to do the repairs that result from poor
maintenance habits than to do oil changes. But, we want to see
you spend you car dollars wisely and get good value for that money.
This is our business philosophy.
In the last five to ten
years the manufacturers have gone crazy extending their oil change
intervals. You have to wonder what they are thinking. My opinion?
Good old planned obsolescence. It seems that they want the
engines to last through the warranty coverage, but not too much longer
than that. It has gotten to the point where some late model
engines are just not available on the used market. Why? Too
much demand for replacement engines, and too few engines are
useable when coming out of the wrecked cars.
Keep in mind
too, that when the time comes to sell your car, you can usually command
a higher price if you have well documented oil changes at short
There is a wealth of information on the web about problems with extended oil change intervals.
I will post links as I encounter them.
