2) Organic Oil - Organic oil is still the industry standard.
While cheaper than synthetic oil, it also breaks down faster. James
Eischen, the auto mechanic from America's Car Show, doesn't advise
leaving petroleum-based oil in an engine for 7,500 miles, as is
recommended with newer engines. He recommends every 4,000 to 5,000
3) Synthetic Oil - According to Aamco, your car benefits from
synthetic oil by having a cleaner engine, reduced wear and better
engine protection at high temperatures, better gas mileage, and
improved cold weather starts.
Synthetic oil is used by high-performance cars because of the
demands put on them, but the benefits also apply to other vehicles
and their drivers. Although more expensive, synthetic oils deliver
benefits to offset the costs, including longer life.
Mr. Eischen suggests synthetic oil can last 5,000 to 7,000 miles
4) DIY or Mechanic? - Changing your own oil offers several
benefits, including cost and convenience.
Doing it yourself saves you a mechanic's bill and lets you schedule
it at your convenience. If you are mechanically inclined, another
benefit is to give you the chance to check your engine for signs of
On the other hand, if you don't like to get dirty or aren't engine
savvy, you might put off changing the oil, and that could damage
your engine. In addition, a mechanic will check fluid levels and
other areas for problems while your car is up on the rack.
5) The standard to change oil used to be every 3,000 miles or
three months, whichever came first. As regulations on emissions and
fuel economy tightened, car engines ran hotter, and oils were
designed to meet those conditions. The new rule of thumb is to
change oil every 7,500 miles.
Your car's vehicle manual will recommend a schedule for normal
driving. If you drive in bumper-to-bumper commuter traffic, haul
heavy loads, or go off-road, you will need to change it more often.
