Oil filter

The oil filter should be change at every other oil change or
200 hours.
To replace the oil filter:
1. Drain the oil by following the steps described in the
previous section of this chapter.
NOTE: If replacing a damaged filter, the filter can be

only.

Fuel system

What you should know about fuel.
Most of the fuel presently available in North America is oxygenated to some extent. This is commonly done
through the addition of ethanol. Most engines offered for sale on outdoor power equipment in the North American
markets are designed to tolerate no more than 10% ethanol by volume
Ethanol is hygroscopic, meaning it absorbs water. If left exposed to air, it will draw water out of the air.
Ethanol is an oxygenator, which means that it will oxidize (corrode) metal that it comes into contact with. Expo-
sure to air causes fuel to go bad quickly, leaving gum and varnish deposits.
Methanol is another type of alcohol that is used to oxygenate fuel. Fuel that contains 5% methanol can be used
as long as it also contains cosolvents and corrosion inhibitors to protect the fuel system. Fuel with more than 5%
methanol will cause starting and/or performance problem. It will also cause damage to the metal, rubber and plastic
components of the fuel system.
Fuel used in Cub Cadet outdoor power equipment should be no more than 30 days old. Because it may already
have been stored at the refinery or gas station for a week or more, fuel should be purchased in small quantities and
stored in safety approved gas cans with the caps closed.
For storage, all fuel should be run out of the tank and engine. Anti-oxidation additives will help keep the fuel
fresher.
