I think this might be a popular thread...

...I assume you intend to do this to a diesel engined W123 and not a petrol one!

Common opinion seems to be that just chucking WVO into your (diesel) fuel tank isn't a smart move if you actually need to reach your destination / want some degree of reliability.

Untreated WVO will gunk up your fuel delivery system and in cold weather it might not even flow. Several people here and on the peach parts forum have spent a lot of time and effort trying to undo the damage caused by this type of activity.

As far as I am aware the whole waste oil get out of jail free card isn't what it used to be anyway - lots of people who used to give this stuff away have worked out that people will now pay for it.

Here in Holland about 5 years ago loads of people tried to drive for free on chip fat - I rarely see any old diesel W123s smelling of what ever food was first used in the oil anymore. About 2 years ago the cost of spare parts dipped quite considerably; I think that this was partly due to lots of people giving up with WVO and scrapping their cars.

1992 190E 1.8 <=>2.0 201.018 => Daily driver

1981 300D (non turbo) 123.130 => Project car - stripped to the bone

1965 Land Rover Series 2a Station Wagon => CIS recovery therapy!

Free and legal FSM download => Ask for help if you get stuck!

Don't leave that there I'll take it to bits

Oh for the love of Benz don't....

PS....there is NO such thing as a cheap Benz......

Unless you want a nice lawn decoration, that will make the neighborhood smell like french fries....I would rethink your plan of action...

You'll just add one more W123 to the junk yard.

In your location NYC; if before shutting down the Engine You did not switch to running Diesel Fuel to flush out the WVO from the Fuel Injection Pump in any sort of cold Weather the WVO would gel up inside of the Fuel Injection Pump housing and is real likely you would not start at all till someway was found to heat up the Housing.

I have read of any systems that heats the Fuel Injection Pump Housing.

Even in an area with Hot Weather all of the time like Florida; having the WVO sit inside of the Fuel Injection Pump over night is bad due to Water and Acids in the WVO.
