I'm red-green color-blind, and I find the difference between the light oil and heavy oil icons to be very subtle. I can't see any difference at all between light oil and lubricant. More distinct colors (and maybe different shapes) would be a welcome change. Heavy oil could be a more vivid red, light oil a more vivid green, and lubricant a vivid yellow. Light oil's icon could be several smaller drops, while lubricant might superimpose a gear to emphasize it's use in machinery.

I can perfectly understand the confusion, they pretty much are just red, green and yellow versions of the water icon.

Sulfuric Acid and Petroleum Gas are a nice change as they use a molecular diagram as their icon. Perhaps all the oil products could use similar changes.

I second this.
Will use color-blind mod for this too (if such a mod will appear somewhere)

Maybe nobody awaits it, but I've made a big list and this is now added there:

I like how you said "light oil should be a more vivid green, lubricant a more vivid yellow", when in reality it's the other way round.
Anyway, I changed the icons like you requested. Just put them into gamefolder/data/base/graphics/icons/fluid.
If you needthe other icons changed as well, just let me know.
