Curious product. MSDS says 60% light petroleum distillates. <4% nasty hydrocarbons. 35% "other stuff". no mention of algicide.

Transporter recommended Morey's Diesel smoke killer and has elsewhere reported on his long-term data collection from vehicles running with that. Have been using Morey's DSK for a few years. Seemed to make a visible difference to soot out the tailpipe (seen in other cars' headlights at night) on non-DPF Polo. Seems to make engine a bit quieter as expected with a higher cetane fuel.
