Generator fuel

[ewald]

I have a diesel powered generator (6kw Stephill with a Yanmar engine) that lives in the garage as a standby. Every year I run it for an hour to make sure it is ok - it hasn't been used in anger for 15 years.
I am pretty sure it still has pre-bio fuel in it, as it starts perfectly - is there any non bio diesel available, as it needs to be reliable the day I actually need it. I don't want to be cleaning filters/bleeding injectors on a snowy night in February when the lights go out. Are any of the additives good long term, or is there a diesel equivalent to Aspen petrol that might be suitable?

Not sure about non-bio diesel, but I know you could buy a barrel of Avtur (aviation turbine engine fuel) which is cheap, keeps forever, stays liquid down to -40C and will run in a diesel engine without modification.

Ring up your fuel supplier and explain the situation, they may be able to get you a drop of GTL diesel which has no bio component and is a heck of a lot cleaner to begin with and so it will store better long term.

Thanks for the replies - something to pursue tomorrow.
