My Nova would burn diesel but what a mess. I got a bit nervous as I now have the Nova+ I also used it for leaded gasolin but had to clean every second day but don't know if it was down to the lead or it just was dirty. I bought it on an atoll in the Pacific.
No, I never really thought about diesel fuel. My concern is why the successor model didn't surpass the previous model and was discontinued.
I don't want to burn diesel. I don't think I'll ever have to. It's easy to imagine that there would be a lot of problems.
Diesel was all I could find in Tibet on a short notice, just before the jeep left for a long trip in the Tibetan "bush"
