Re: 1976 Mercedes 300D - WVO conversion
Some people do, which is why the buzzer was provided in the first place.
I do not have a recommendation for this for any vehicles but mine. Either of my Mercedes 300Ds will start from cold on 100% veggie (I found this out by forgetting to purge!). I prefer not to cold start on veggie, to avoid coking issues, so if the engine is going to be very warm when the break in my journey is finished, then I do not purge. If I am stopping for more than 1/2 hour in winter or 1 hour in summer, then I will purge. I also consider the wind conditions as these can drastically cool the engine quickly in winter.
Other vehicles and climatic conditions will be different.
Another thing to consider, is that some people suggest that the coking of injectors is due to a dribble of oil on the injector tip as the engine stops, being polymerised due to the heat and presence of air. I have not seen any studies to show whether this has a big effect or not, but dribbling injectors cause a loss of power and economy. It should not be an issue with properly adjusted injectors.
In my Capella, I used the 'shut-down delay' defeat button to allow immediate shut-down for short breaks in my journey where I did not wish to purge.
Regards,
Tony

I personally had no trouble remembering to change back from vegy to bio or diesel and my wife also drive a converted car for a while now and never forgotten.
I guess the fear of forgetting comes with the stong warning advise we give to people wanting or about to convert their cars. For example I often drove long hours "over 18 hours a day" and used to come home really falling a part yet I never forgotten to change over. I also spend 10 hours in studio recordings and come out with painful headache and still do not forget to switch back to diesel. Owners of the cars I converted are also finding it very easy thing to remember.
Thanks again for the info. I will look into it in depth for sure.
Tony, What if I went for a long drive and only stopped for a coffee where I do not need to change over?
