Is There a Mobil 1 SAE 30 Oil that Will Handle Generator Requirements?
I have a Generac 20 KW Natural gas generator with a 36 horsepower V-Twin aluminum engine that recommends SAE 30 Oil for protection from 32° to 110°F. According to my manual SAE 10W-30 only protects from -10° to 40°F. Amsoil (Formula 4 stroke 10W-30/SAE 30 Small Engine Oil) is the only oil that I can find that meets the requirement. I have always used Mobil 1 and now use Mobil 1 Extended Performance in all of my automobiles and lawn equipment. Is there a Mobil 1 full synthetic oil that I can use in my generator and still meet the SAE 30 requirement. I live in south Louisiana and temperatures reach a 100° but also needed the generator in 20° weather last winter. The recommended oil change is 2 years or 200 hours.

We recommend you use Mobil 1 5W-30. It protects well over a wide range of temperatures and outperforms conventional oils.
