What Weight of Oil Do You Use in a Craftsman Snowblower?

Oil Viscosity

• Oil viscosity measures how quickly oil will move at 210 degrees Fahrenheit. That viscosity rating translates into the oil weight, which indicates the best temperatures for use. Lower-weighted oil moves faster at low temperatures, while higher-weight oil lasts longer at high temperatures. Multi-weight oil changes property at different temperature ranges, giving it more versatility. Low weight oil will burn up fast if you use it in high ambient temperatures. It can take a while for high-weight oil to heat up during low ambient temperatures.

Recommended Oil Weight

• For Craftsman snow blowers, the recommended standard weight is 5W30. That weight is optimal for using your snow blower between -20 and 40 degrees Fahrenheit. SAE 10W-30 is an acceptable substitute. For operating at temperatures 32 degrees and above, use SAE 30. It’s also possible to use synthetic oil, which has less contaminants than petroleum-based oil but can cost more. If operating at 40 degrees and below, you can use synthetic SAW 0W30.

Lubrication

• In addition to lubricating your engine, the oil can be used to lubricate other parts of your snow blower. Lubricate all the chains, sprockets, gears, bearings, shafts and the shifting mechanism at least once a season or after 25 hours of operation. Ensure that you don’t get oil on the aluminum drive plate or the friction wheel. If you don’t have engine oil, use a spray lubricant instead.

Oil Maintenance

• Engine oil’s natural contaminants can contribute to clogging and damaging your engine if it isn’t changed. The contaminants reduce friction capability. The maintenance schedule directs to change the oil after the first two hours of operation and every 25 operating hours after that. Check the oil before each use and add according to the dipstick reading. Oil levels should be between the “full” and “add” mark. When adding oil, do not exceed the maximum oil capacity according to the manual.
