Up the veg to 30% and there will be a difference.

It is best to mix it out of the car before putting in the tank,if it has to travel around the fuel system to get mixed it takes longer to notice the effect.

My previous car was a Bmw 525tds turbo inter cooled diesel 1994,anything over 30% veg gave no extra power.The 30% seemed the optimum mix with diesel .

You will notice a bit more zip,not much but the engine will be a bit more eager to rev.

On the Bmw which was all edc controlled fly by wire the veg mix would be noticeable in firmer gear changes on the auto box depending on how much percentage of veg added.

The veg giving more energy see's less throttle pedal for a given speed so the ecu would sometimes see up to 1/2 inch or less pedal position and this coupled with the ecu controlled gear box resulted in firmer shifts.

The Bmw would lock up into 5th gear and cruise along ticking over at 1800rpm around 80mph,approaching an incline it would just drop itself down into 4th gear to hold the speed and then over the top and on the level would lock back into 5th.

The added veg would see it hold 5th longer or not change down at all.

Towing a heavy trailer this was a bonus as more often than not it would only go into 5th on a down hill stretch using only diesel,so the 'less pedal position' fooled the ecu into thinking the engine was not working to hard and it would go into 5th .

Kerosene is commonly used in northern climates to replace #2 (diesel) because at temperatures below -30deg f, it will not gel. Notice I said -30deg f. You should not have to add kero in SC ever. Just for the record, it costs more than #2, and is not as efficient.

Unless you are a meticulous, obsessive/compulsive person you should stick with the fuel that God meant MB to use- undyed diesel from the pump. This forum is filled with instances of people buying old diesels and then subsequently posting that the cars "wont start", "run rough", or are dying along the road. Its a shame to read about. For the price of a new injector pump, the smell of french fries is a large price to pay... it seems like the primary killer might be technique-- ie, how you treat your "free" oil before dumping it in the tank. So before you leave the fuel distribution system behind, make sure you are set up to do this.

WVO and biodiesel both have LESS ENERGY CONTENT per kg or liter, so it is not really possible to make more power using it. Most any effect is placebo or some minor effect due to some feel that cannot really be there.

Have any dyno runs to show more power on WVO?
