MAINTENANCE & ADJUSTMENTS

Running the engine with persistent spark knock or pinging

can cause engine damage. This type of damage is not

covered by the Distributor’s Limited Warranty.

Oxygenated Fuels

Some conventional gasolines are being blended with alcohol

or an ether compound. These gasolines are collectively

referred to as oxygenated fuels. To meet clean air standards,,

some areas of the United States and Canada use

oxygenated fuels to help reduce emissions. If you use an

oxygenated fuel, be sure it is unleaded and meets the

minimum octane rating requirement.

Before using an oxygenated fuel, try to confirm the fuel’s

contents. Some states and provinces require this information

to be posted on the pump. The following are the EPA

approved percentages of oxygenates:

l

Ethanol (ethyl or grain alcohol) 10% by volume

You may use gasoline containing up to 10% ethanol by

volume. Gasoline containing ethanol may be marketed under

the name “Gasohol”.

l

MTBE (methyl tertiary butyl ether ) 15% by volume

You may use gasoline containing up to 15% MTBE by

volume.

l

Methanol (methyl or wood alcohol) 5% by volume

You may use gasoline containing up to 5% methanol by

volume as long as it also contains cosolvents and corrosion

inhibitors to protect the fuel system. Gasoline containing

more than 5% methanol by volume may cause starting

and/or performance problems. It may also damage metal,

rubber, and plastic parts of your fuel system. If you notice

any undesirable operating symptoms, try another service

station or switch to another brand of gasoline.

Fuel system damage or performance problems resulting from

the use of an oxygenated fuel containing more than the

percentages of oxygenates mentioned above are not

covered under warranty.
