The Fuji BT32 manual states to break the engine in with an hour or so of run time at 25:1.
After that, 40:1.
Does not specify either synthetic or petroleum oil.
After reading 100 posts about break-in and getting 100 opinions, please advise:
Can I break this engine in on synthetic, since thats what I plan to run in it.

Thanks,

As far as time and procedure, follow the instructions. For oil, it's not important whether the oil is synthetic or petroleum based. If the oil's intended for small two-stroke engines, it's OK.
