How to Identify the Lawn Mower or Small Engine Oil Type
Consult your engine operator's manual for information specific to your engine. Proper care and maintenance of your equipment is proven to be the key to long engine life. Prior to each engine start, always check the oil dipstick for proper oil level. If you have new equipment or a new engine, oil typically does not come already added.
Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to select the best viscosity for the outdoor temperature range expected. Engines on most outdoor power equipment operate well with 5W30 Synthetic oil. For equipment operated in hot temperatures, Vanguard 15W50 Synthetic oil provides the best protection.
*Below 40°F (4°C) the use of SAE 30 will result in hard starting.
**Above 80°F (27°C) the use of 10W30 may cause increased oil consumption. Check oil level more frequently.
