Veg additive

[ally406]

Veggie and bio folk often use 2EHN (2 Ethylhexyl Nitrate) which increases the Cetane index of the fuel. This is the active ingredient in the likes of Redex and such, but these products have it very diluted. I haven't seen anybody say it doesn't work, and there is indeed a proper research paper floating around out there that shows that it is effective in derv fuel. Adding petrol to veg is a very effective at reducing viscosity but unfortunately it is also a serious cetane retardant, which can be overcome by using 2EHN. I run 80/20 WVO/misfuel all year round and use 2EHN at 0.1% as a matter od course, the biggest thing I notice is improved cold starting.
