If you mean blending the yes, have probably blended for more than 100 000km in total (62 000miles) over the last 12 years both with SVO and WVO

with only this car I have alrady blended for 10 051km, actually have a blend between kerosene(ULSD) 45% and unused canola oil 55% in the fueltank right now

Do such blends pollute less? Is it cheaper to run?

yes it does, burning biodegradable oil instead of fossil fuel is better, less soot and more power, atleast compared to the kerosene"diesel" we have here

yes, saves me quite a bit of money since I only buy canola oil when it is on promo and cheaper than the gas station crap

hopefully my friend will start filtering his WVO so i can start with that(even cheaper) before it gets cold again

the downside is that winter is no good with blending, oil turns into butter instead of liquid.... and we all know that fuel lines in traditional cars can only transport liquids right?

another downside is how BLENDING ONLYS WORKS ON OLD CARS like mine with mechanical fuel injection and preferably prechambers, common rail and all these electrical injection systems cannot handle the increase in viscosity, so the limit is said to be cars built around year 1995 and earlier or thereabout, it depends on the car. Some might even be earlier (or later)

I admire these cars and their reputation for reliability. Wouldn't mind owning one someday.

The thread reminds me of pgfpro, who was running an Eagle Talon on paint thinner. Cool stuff.

I think my car is capable of burning ethanol but I guess there's really no cost/efficiency savings to that.

I Like these cars A LOT. The W123 and W124 in particular. I drove a manual 250D once, it gives a very robust feeling. And that sound, wow. The quality of those cars are from a very high level, so congratulations for owing a car like that. Hopefully I can say the same someday!

Like the Toyota Hilux that Top Gear couldn't wreck, these
Merc's are indestructible too. I remember Fifth Gear tried it with a 250D. Only downside is that they rust easily.

Old-school indirect-injection Diesel engines actually get a better mileage with vegetable oils than with either regular Diesel fuel or biodiesel.

It depends, there used to be many vegoilforums, but now many are gone.... most people there reported same fuel milage or slightly worse with vegoil compared to diesel but this was about 10 years ago (damn i am getting old)

All i know for sure is that the kerosene "diesel" in gas stations here is a lot worse than vegoil, hvo and real diesel from rest of europe/the world

Have you tried blending? Most gas cars can handle 20-40% E85 and usually there is no ill effect in fuel consumption until about 35% E85 blend

I like them too, that is why i have two perfect when driving long distances, quiet and comfortable, my former cars (volvo 240) are also legendary but a lot louder, a bit too loud for comfort when driving long distances like I do now

Like with all old cars rust is the biggest enemy

Thank you guys

With emissions compliance being developed only around regular Diesel fuel and occasionally some low biodiesel blends, such outcome is quite predictable, not to mention the unfair regulations preventing older cars to access central areas of some cities due to their emissions certification even if they can be easier to adapt to use a less-polluting fuel.

With direct injection it usually increases fuel consumption while using veg oil, while the opposite happens for IDI.

So time for an update, getting used to her now and with more low throttle power from removing throttle plate.

my driving is most of the time letting up the throttle enough to make the autobox shift at around 2500rpm and also coasting as much as possible, accelerating is still heavy on throttle (and same uphill) most of the time my speed is 75-85km/h, the speedlimit is mostly 80km/h so I follow traffic rythm pretty well
