Oil recommendations

Commercial Engine Oil Recommendations by Vanguard Engines


*Below 4°C (40°F) the use of SAE 30 will result in hard starting and could cause a lack of lubrication failure.

**Above 27°C (80°F ) the use of 10W-30 may cause increased oil consumption. Check oil level more frequently.

  • SAE 30 5°C and higher (40°F and higher) is good for all purpose use above 5°C, use below 5°C will cause hard starting.

  • 10W-30 -18 to 38°C (0 to 100°F) is better for varying temperature conditions. This grade of oil improves cold weather starting, but may increase oil consumption at 27°C (80°F) or higher.

  • Synthetic 5W-30 -30 to 40°C (-20 to 120°F) provides the best protection at all temperatures as well as improved starting with less oil consumption.

  • 5W-30 5°C and below (40°F and below) is recommended for winter use, and works best in cold conditions.
  • For continuous-use, such as commercial lawn cutting or pressure washing, use Commercial Grade Engine Oil 15W-50 Oil (temperatures from -7°C to 54°C (20°F to 130°F)).

Type of oil to use

  • Use a high quality detergent oil classified "For Service SF, SG, SH, SJ" or higher.
  • Do not use special additives.
  • Choose a viscosity according to the table above.

To view the most current information regarding oil type and capacity specific to your engine, please view your engine Operator's Manual online. Engine Break-in procedures for both Synthetic and standard oil remain the same.

Synthetic Oil Caution API Service

 

 

Note: Synthetic oil meeting ILSAC GF-2, API certification mark and API service symbol (shown at left) with "SJ/CF ENERGY CONSERVING" or higher, is an acceptable oil at all temperatures. Use of synthetic oil does not alter required oil change intervals.
