昔の2stの雑誌のワコーズの人の話によると、2stオイルはそこまで燃えてないらしいね。
燃やせるように設計してないてよ。燃えると言っても精々3割らしい。
煙が出るとか出ないとかは成分によってマフラーからの排出され方が違うだけって話

Arctic Diesel fuel(ロシア規格) 動粘度1.4mm^2/s以上(20℃)
日本の灯油(JIS1号･白灯油)はおおよそ動粘度1.3mm^2/s(30℃)

Chilling temperature: −5 °C. It is produced by mixing the straight-run, hydrotreated and
secondary hydrocarbon fractions with end boiling point of 180-360°C. End boiling
temperature rise lead to intensive coking of burner nozzles and smokiness.
Winter diesel fuel: Density: not more than 840 kg/m³. Flash point: 55 °C.
Chilling temperature: −35 °C. It is produced by mixing the straight-run, hydrotreated and
secondary hydrocarbon fractions with end boiling point of 180-340°C. Also, winter fuel is
produced from summer diesel fuel by adding the pour-point depressant which reduces the
chilling temperature of fuel, but low change the maximum filterability temperature. Using
obsolete technique 20 % of ТC-1 or KO kerosene is added to summer diesel fuel, but
performance properties are not changed at all.
Arctic diesel fuel: Density: not more than 830 kg/m³. Flash point: 25 °C.
Chilling temperature: -50 °C. It is produced by mixing the straight-run, hydrotreated and
secondary hydrocarbon fractions with end boiling point of 180-320°C. Boiling range of
arctic fuel is approximately similar to boiling range of kerosene fractions, so this fuel is
extra heavy kerosene in its properties. However, clean kerosene has low cetane number
of 35-40 and insufficient lubricating properties (e.g. severe wear of fuel injection pump
assembly). To solve these problems, arctic fuel is supplemented with additives increasing
cetane number and mineral motor oil to improve lubricating properties. More expensive
method of arctic diesel fuel generation is dewaxing of summer diesel fuel.

JIS1号灯油 270度以下
JIS2号灯油 300度以下
90%留出温度を計算すると
JIS1号灯油 260度
JIS2号灯油 288度
終点(100%)を計算すると
JIS1号灯油 283度
JIS2号灯油 315度
