What is more, you can even use 5W30 oil instead of 10W30 in your generator or engine, if needed. Both these types of oil actually have the same viscosity and this means that the oil will perform the precise same way once it reaches operating temperature and therefore can be used interchangeably.

Can I use 5W20 instead of 5W-30 in generator?

Can you use regular engine oil in a generator?
On balance, synthetic oil is normally preferable and will let your engine run for much longer. Ultimately though, 5W30 or 10W30 are fine in most cases, for most vehicles and generators. Likewise, you'll often find that using either mineral or synthetic oil is fine.
