i think the fuel values it's patching are outdated...
the new fuel values of ks_power are
local fuel_values = {
["crude-oil"] = "1.4MJ",
["light-oil"] = "1.5MJ",
["heavy-oil"] = "1MJ",
["petroleum-gas"] = "1.5MJ",
["diesel-fuel"] = "2MJ",
}
but i personally recommend something like
local fuel_values = {
["crude-oil"] = "0.4MJ",
["light-oil"] = "0.9MJ",
["heavy-oil"] = "0.45MJ",
["petroleum-gas"] = "0.45MJ",
["diesel-fuel"] = "1.1MJ",
}

if my patch are obselete, it's a good news =)

nope...
1. klonan still has no trigger_created_entity event
2. this mod, and the original flammable oils too, is loaded before ks power. ks power has the same algorithm of saying "if theres no fuel value yet, we don't set the fuel value" so only this mod's fuel values are applied, whose are 3x higher than the intended amount in ks power

excuse my basic english, but my mode are still usefull but i need ajust it ?

yes

add an optional dependency for ks_power
and change the fuel values to the ones i sent you or the ones in ks_power
you can use google translate if you have problems understanding me

i understand english well, and i use googletrad/reverso if nessecary
but i'm not dev ot mods, just host :/
i need learn how fix that
and find motivation...

could you help me to update the mods with good value ?
