Does Griffa's Adaption skill affect the flamethrower consumption?

Solution 1:

According to PCGamer in this article, the Adaption ability does reduce the amount of fuel that flame throwers on the Magnum Opus will use.

From the article, when referring to the use of the Adaption skill and flame throwers (emphasis mine);

This will change all of the sudden late in the game when you get the chance to add flamethrowers to your car. They're useful, no doubt, for keeping cars from smashing into your sides and setting enemies on fire, but boy do they drink up the go-juice. In other words, throw a token into Adaptation every so often, even if you feel like you don't need it.
