Engine Oil and Filter (cont'd)
Fuel Efficient Oil For the best fuel economy from your car, it is recommended that
you use a fuel efficient SG grade oil. This oil is usually identified by
the words such as: "Energy Conserving II," "Gas Saving," and "Fuel Saving," etc.
Changing Oil and Filter
Engine oil and filter should be changed together every 6 months or
7,500 miles (12,000 km), whichever comes first. The filter is located
on the engine block, below the intake manifold. A special "cap
type" oil filter wrench is required (available from your Honda dealer). Use only a genuine Honda filter or its equivalent.

CAUTION:

The oil filter cannot easily be removed from above the engine. For
this reason it is recommended that the oil filter change be done by a skilled mechanic.
1. Start the car to warm up the engine, then shut it off.
2. Remove the engine oil filler cap and drain bolt, and drain the oil.
A warmed-up engine and the oil in
it are hot; be careful not to burn yourself.
3. Remove the oil filter and let the remaining oil drain out.
4. Install a new filter according to
the instructions on or with the

filter.

5. Reinstall the drain bolt with a new washer and tighten it securely.Refill the engine with the recom-
mended oil, to the upper mark on

the dipstick.
