Frequently Asked Questions (FAQS)

Can I use synthetic oil in my generator?

One major advantage of synthetic oils over other motor oils is their ability to lubricate faster. They can work in generators and most people like them since their performance is not affected by temperatures.

What does SAE 30 mean?

SAE stands for Society of Automotive Engineers, a standards development organization for the engineering industry. The organization rates engine oil in terms of viscosity, that is, its ability to flow. Engine oil with SAE 30 rating means that this organization ran it through a tube-like device to see how many seconds it will take to flow the other end. The seconds are then rounded on to the next tens. Hence, SAE 30 means that the oil took approximately 30 seconds to flow.

What is the difference between single-grade rating and multi-grade rating?

SAE 30 is an example of a single-grade rating. It indicates the weight of the oil in warm temperatures. However, temperature affects the viscosity of the oil. Thus, this type of rating does not bring out the exact properties of the oil under all temperature conditions. That is why a multi-grade rating is important. 10W-30 oil, for instance, is an example of a multi-grade rating. The 30 in this rating denotes the same thing as the 30 in the SAE 30. However, the 10 stands for the viscosity of the oil in winter (W) conditions, hence 10W.

How do you maintain a generator?

Firstly, you need to maintain a healthy oil level and change it when necessary. Also, you need to keep the unit and the air filter clean. Proper storage and running it at least monthly are equally essential.

When should I change my generator oil?

When new, most generators will need you to change after 25 hours of continuous use. However, after the first oil change, most will need fresh oil every 50-60 hours.

Verdict

Proper maintenance of standby generators enhances their reliability and improves their lifespan.

With one of these oils, your generator will run smoothly, efficiently, and effectively and will cause minimal to no troubles in the future. Just examine our options to find out the ideal option for your machine.
