Dear Biodiesel, SVO WVO drivers:

I read on Mercedessource.com that the plastic pre-filter
can melt, on my 300SD or 300D that is running on
vegetable oil / WVO / SVO / that is heated.

Did anyone experience melted or disfigured pre filter ?

Plastic pre Filter

Hello, I just installed a Mercedessource set of kits in a 84 300SD the heater in the trunk (spare tire well) has a plastic preheater installed on it from MercedesSource right after the heater, however this heater is only set to 110 degrees. The front unit also has a clear plastic heater installed on it as well and that heater is set to 150 degrees. I have 1500 miles on the install so far and they have not melted or warped in any way. I do not know what Kent meant by that comment as his kits come with those pre filters. The Kits are great, I have had problems with the switches 3 have died in some way or other and 1 Pollak valve has leaked. The instructions were ify at the time I do not know if he has revised them as yet.

I don't know the prices in the US, but in europe there are insane taxes for gasoline and diesel. The price for both is about 30CZK/liter and over 10CZK is a consumer tax, about 6CZK is VAT. With vegetable oil those do not apply - vegetable oil costs about 17CZK/liter and can be bought for much less from time to time...

My 300SDL has the two tank conversion. Running on waste vegetable oil is basically free. Restaurants have to pay someone to haul the used vegetable oil away and most will gladly give it to you for free. Take it home, filter it, and put it your second tank. I just drove from DC to Atlanta and back for pretty much free.
