III. Oil and Fuel Specifications

A. Oil

To operate engine you need to use a clean, high quality, detergent oil. For recommended engine oil, see Table 1.

In addition, you need to be sure the oil sump contains the correct amount of oil to operate properly. For recommended oil sump capacity, see Table 2.

NOTES

Be sure original container is marked A.P.I. Service “SL/SJ”.

Using multigrade oil above 32°F (0°C) will increase oil consumption. SAE 10W40 is NOT recommended.

Tecumseh special-formulated oils are available at your Authorized Tecumseh Servicing Dealer.

B. Fuel

Use unleaded regular, unleaded premium or reformulated automotive fuel only. You may use gasoline containing the components identified in Table 3.

DO NOT use leaded fuel.

Fuel must be fresh and clean. NEVER use fuel left over from last season or stored for long periods.

NEVER mix oil with fuel.

DO NOT use fuel containing Methanol (Wood Alcohol).

IV. Before Starting Your Engine

A. Checking Oil Level

To avoid engine damage, it is important to:

Check oil level before each use and every 5 operating hours when engine is warm. Check oil level more frequently during engine break-in.

Keep oil level between “FULL” and “ADD” marks on oil fill cap/dipstick or to point of overflow on engines with an oil fill cap/plug. See Figure 7.

Be sure oil fill cap/dipstick or oil fill cap/plug is tightened securely.

NOTES

DO NOT overfill oil filler. Doing so may result in oil carry- over to the equipment and cause malfunction or damage.

DO NOT allow oil level to fall below the “ADD” mark on oil fill cap/dipstick. Doing so may result in equipment malfunction or damage.

Contact your Authorized Tecumseh Servicing Dealer for Tecumseh Oil.

Some engines are equipped with a oil fill cap/dipstick or oil fill cap/plug (see equipment manufacturer’s instructions). To change the oil on your engine, see "B. Changing Oil" instructions on page 17.
