I want to build a defense wall with flamethrower turrets, but am unsure whether to use heavy or light oil. I read somewhere that light oil is more valuable, ist that true? On the other hand I have more light oil at hand, so why not use it?

Oil itself is generally the best to use. Flamethrower turrets are strong enough to toast everything, and walls (do use walls, double thick) will always take damage because the turrets don't aim ahead/the flame stream is slow.

If you want to use the higher-damage oils, be aware flame turrets only use 3 per second and you don't need to stack them densely like lasers/guns.

A spoiler about flamethrower turrets one weakness:

Wiki says light oil gives +5% damage comparing to heavy oil. I think 1/20 difference is negligible. Just look at this proportion: ooooooooooooooooooox. Compare “x” to “o”. It is not worth to bother, use any of them and boost Refined flammables research. I use crude oil, and I'm happy.

Not worth it for the damage, but you can extract some petroleum from the crude instead of burning it directly. On the other hand, turrets so insanely little oil that it doesn't matter.
Also you can easily drain your LO reserves if you supply a long line of turrets. Not so much from the turrets themselves, but the pipes

I would quote this as the right answer, I guess it doesn't matter what you use.

which is why I always use crude: easiest on logistics, can often find a local source, no danger of running out if other processes back up
