No, you can not always use synthetic oil in a generator. Many brands recommend breaking in their generators with petroleum-based oil types, not synthetic oil.
After that break-in period, 5W-30 full synthetic oil is often (but not always) among the recommended oil types.
You ultimately want to check the recommended oil type in the user manual of your specific generator to avoid voiding your warranties and getting any technical issues.
Common generator synthetic oil guidelines
It is often recommended to break in your generator with the right petroleum-based oil types (often SAE 10W-30 oil).
After that, you can often use certain types of synthetic oil.
The guidelines around synthetic oil can vary from brand to brand and generator to generator.
Ideally, you want to check the user manual of your generator or the model you are considering.
Knowing what oil types generators typically take is helpful but may not apply to your specific machine.
There are a decent number of brands that recommend breaking in the generator with petroleum-based oil (of the recommended types).
After the break-in period, many generator brands include at least one type of synthetic oil (often 5w-30 full synthetic oil) in the recommended options.
How long will synthetic oil last in a generator?
According to Car Care Camp, synthetic oil could last one year in an engine and potentially two years if you are dealing with new, quality oil.
However, changing the oil every 100 hours of use or 6 months is typically recommended by generator brands.
It is typically smart to follow these oil change intervals to keep your warranty and avoid issues.
