Engine Oil; Inspecting Engine Oil Level - Mazda mx-5 2003 Manual

Engine Oil

M Recommended Oil
Oil container labels provide important
information.
SAE
10W-30
The quality designation SG, SH, SJ, SL,
or ILSAC must be on the label.
Engine oil viscosity, or thickness, has an
effect on fuel economy and cold-weather
operation (starting and oil flow).
Low-viscosity engine oils can provide
improved fuel economy and cold-weather
performance.
But high-temperature weather conditions
require higher-viscosity engine oils for
satisfactory lubrication.

When choosing an oil, consider the
temperature range your vehicle will
operate in before the next oil change.
Then select the recommended viscosity
from this chart.
Using oils of viscosity besides those
recommended for specific temperature
ranges could result in engine damage.
Energy conserving oils are recommended.
A chief contribution they make to fuel
economy is reducing the amount of fuel
necessary to overcome engine friction.
M Inspecting Engine Oil Level
1. Be sure the vehicle is on a level
surface.
2. Warm up the engine to normal
operating temperature.
3. Turn it off and wait 5 minutes for the
oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and
reinsert it fully.
