I would run the engine on conventional oil for the first 100 hours or so then switch to synthetic.
Synthetic oil for generator break in.
Another type of oil that is very often recommended by owner s manuals is the sae 5w 30.
Common high performance synthetic oil is so slippery it will actually inhibit the wear required to bed the rings in.
Well my daughter lucky gal just bought a new 2007 pontiac solstice and lo and behold the car comes equipped with synthetic oil from the factory corvettes vipers and many others do too.
I don t have experience with that brand but it is from china and that tells me all i need to know.
However it is better to use synthetic oil in a generator because motor oil cannot match the performance or protection given by synthetic oil.
Since generators usually take little oil i think a better way would be to get a 5l bottle of cheapest mineral oil you can find or better yet proper break in oil do a few flushes break ins then drain and fill with synthetic.
Refilled the engine with supertech 15w40 conventional diesel oil and ran the generator another two ish hours under the same.
This oil will keep the engine lubricated so that it does not break down quickly.
After the 5 hour break in period change the oil.
My opinion on pulsar generators.
This allows the internal parts to break in or wear together to proper fit before switching.
For the 5500 model that time limit is.
The goal is to use an oil which will allow enough friction for the rings to bed in correctly.
The first 5 hours of run time are the break in period for the unit.
So you don t want to use super slick full synthetic oils to break the engine in reveals simon.
The honda 10w30 is nothing fancy conventional oil.
During the break in period stay at or below 50 of the running watt rating and vary the load occasionally to allow stator windings to heat and cool.
Some generator users were able to go over 500 hours using synthetic oil and did not make a change.
For year round use synthetic high mileage oil 10w30 or 0w40 is a good option.
Onan generator oil change frequency 4000 5500 different generator models have different oil change deadlines.
Adjusting the load will also cause engine speed to vary and help seat piston rings.
Should i break it in with a less expensive oil and then go to an exotic synthetic.
This oil is perfect for generators that will be used in slightly colder climates as it ensures easier start and better viscosity at lower temperatures.
