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

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.

If dealing with a dealer does'nt he sell the oil , Other wise read the
manual and follow it Don,t use 10/ 30 as it is not for small engines.

Manual specifies 10w-30, only SFor SE; but I figure they haven't even been
made for years.
