Home made Petrol - part 2

[4door_Sleeper]

I thought I'd start a new thread about this type of synthetic petrol, as its different from the other thread that talks about a diesel substitute. This fuel (called synjuice) is meant to be a substitute or blend for normal fuel (super or unleaded)

I have an issue of "modern MOTOR (may 1974)" – the height of the fuel crisis - which has a formula for making your own petrol. It consists of a blend of :

Toluene (65%)

Benzol (25%) – can be replaced with industrial alcohol but this wasn’t tested

Naptha (10%) - Heavy naptha, water-white)

Mix the ingredients (by volume) stir and poor in the tank through a strainer (you can get sediment from the naptha occasionally)

This mix is compatible with existing fuel and can be run on its own or in a blend.

This mix was tested on various cars of the day and "they all performed better and gave better economy .. than on either standard or premium octane petrol" - **I would be interested to know the octane rating of this mix, but I guess it must be in the mid nineties**

The article went on to say "we tested this petrol substitute in many vehicles without experiencing any trouble or damage to engine or any other vehicle components." but then went on to say "we accept no responsibility for any damage that might occur" (which makes sense to cover their own backs.

Has anyone ever come across this before, know anything else about it, or tried it to see if it works.

Won't the toluene cost you more than the equivalent of BP Ultimate?

yeah, and im pretty sure that they couldent test for the long term aswell, might interfere with the ecu or something...

i don't know about the price of toluene (naphtha is the active ingredient in zippo fuel tho :flamed: ..) ive never even heard of it before lol... but the point about the ecu's is definatly valid, im pretty sure that cars back around 74 with ecu's where rare as. but if it does supposedly have all the benefits that modern motor claim it to have; then it could be worth (or not) moding the ecu... but it is worth researching at the least. ill look into it and get back to ya's....

How do you see it effecting the ecu? I agree that it may need tuning depending upon the octane rating, but other than that I cant see how it would have any effect (or am I missing something?)
