5-8 percent of 2 stroke is plenty.By the cheapest stuff you can get. It will still do the job. I would stay away from sump oil, gear oil regular motor oil and sawchain oil
. It is not made to burn together with fuel, or burn at all. This can cause more friction, than lubrication of the combustion cycle. 2 stroke oil will allso lube the injectors with minimum polutants.
When it comes to water contamination its not a bigger problem with Ja1 than normal diesel. Same outcome will exist with water in the system, filter clogs with water and engine stops.
Fuel tanks on diesel cars most often have a "sump" where water can accumulate and not go to the engine.
Remember you can mix it with some normal diesel to.
In cold weather areas the sell what they call "winter diesel". This is because diesel freezes bellow -15 celsius. "Winter diesel" is normal diesel mixed with kerosene to lower the fresing temp. Kerosene=jet a1
If you want to use jet a1 on a new complex turbo/HDI diesel engine id go 50\50 with diesel just to be safe. I do however, know i guy how runs a fairly new Mercedes with HDI engine on Jet A1+ 2stroke with no problem.
