My understanding is that you have to use motor oil that "at least"

a generator also?

I got my Yamaha EF1000 today. The instructions call for SE or SF
oil; all I had was SL. Is there any reason that might not be okay?

I know, "Call Yamaha". I had to call them three times to verify that
a claim made in one of their retailer's ads (that it will do 3500w
for 3 seconds) was accurate; I doubt I can actually reach anyone
there who knows what oil is. Not that Yamaha doesn't know what oil
is; they just don't let those people talk to customers.

Thanks.

The "S" means Spark (gasoline) [opposed to C which means compression
(diesel)]. The second letter is 100% backward compatible, that is the later
letters (what will be do when they hit Z?) The later oils can do
everything the earlier ones did and more.
