Hello,
I'm from Quebec, Canada, and I have a Liberty CRD 2006, with about 50000 miles. Here, the price of diesel is going crazy, about 5.6 $ / gallon, so I decided to try to use a WVO mix. So, could anybody tell me, please, what WVO mix (I mean WVO with gasoline, or diesel or what-else and what is the percentage) can I use without making any modifications to the engine? I mean, there is anybody who has a successful recipe? I read on a forum about somebody who uses 80% WVO and 20% gasoline and runs his Jeep for about 4 years without any problem. Is this the ideal mix? Thanks for your answers.

It will not start right on that mix or probably any other mix. And you will probably just clog expensive diesel filters. Especially in Canada. As I recall it is usually really cold there.

Your best bet is a full conversion and start up on diesel. It is not a hard conversion. I have lots of detail on how I did mine. You would need a fully heated tank ($300-400) depending on size and shape. 2 greasecar valves ($200) fuel line and fittings ($200) FPHE and insulation ($120) and injection line heater for the common rail ($40). You can build a nice system for less than $1000. And a few days labour. Payoff is quick at $4 per gallon assuming you have free grease and a way to filter it. But you have to have that anyway if you are going to blend the fuel.

So, there is not a mix who will run well without modifications? I'm not a fuel expert at all, so even, I don't know, a 50% oil, 50% gasoline will not make something close to diesel fuel, something to save some money?

I run a 75/15/10 (WVO/RUG/DSL) mix during the warmer months in mine. You could run 80/20 but the flashpoint is a little lower than dyno diesel. I wouldn't run any more that 17-18% RUG. Don't run mix if the temps outside at any point drop below 45 deg. F or the fats will separate out and clog your filter.

Have successfully run 80/20 diesel/WVO all winter. 6000 + miles
Currently running 65/35 diesel / WVO.
Ran 50/50 mix all summer. Needed line heaters as the temps started to drop below 50 in the fall.
Using Diesel Clean additive helps.
