SAE low-30
As shown in the viscosity chart, SAE low-30 is best
for your vehicle. However, you can use SAE 5W-30
if
it’s going to be colder than 60 F ( 16 C) before
your next oil change. When it’s very cold, below
0 F (- 1 8 C), you should use SAE 5W-30.
These numbers on an oil container show its viscosity, or
thickness,
Do not use other viscosity oils such as SAE
1OW-40 or SAE 20W-50.
Energy Conserving I1
Oils with these words on the container will help
you
save fuel.
This doughnut-shaped logo (symbol) is used on most oil
containers to help
you select the correct oil.
You should look for this on the oil container, and use
only those oils that display the logo.

secondary hood release. Lift the hood.
Most trips are less than 4 miles (6 km).

0 The engine is at low speed most of the time (as in
0 You tow a trailer often.
0 Most trips are through dusty places.
If any one of these is true for your vehicle, then you
need to change your oil and filter every 3,000 miles
(5 000 km) or 3 months -- whichever comes first.
(See “Change Oil Soon” in the Index.)
If none of them is true, change the oil every
7,500 miles
(12 500 km) or 12 months -- whichever comes first.
Change the filter at the first oil change and at every
other oil change after that. (See “Change Oil Soon”
in the Index.)
Engine Block Heater: An engine block heater can be a
big help if you have to park outside in very cold
weather,
