pre heat
Mercedes are very forgiving at what temperature you put the oil in the car. It's not good to put cold oil in there though... Let me correct myself, it's not good to put cold oil through your injectors.
Use a Flate plate heat exchanger at least and add some tank heat would be my recommendation.

I've started on and run >50% WVO at temps around 40°-45°F. Not recommended but, an unexpected cold snap came before I'd had a chance to add diesel to the tank.
Other than start-up, I think it would be hard to subject injectors to 'cold' oil because the injector body is subjected to combustion temperatures and thus, will actually heat the oil some before it's injected. Using my non-contact thermometer on them, at operating temp the base of my wagon's injectors runs about 200-220°F. One of these days, I'd like to rig a thermocouple in the return line to determine the temp of the flow.

The oil won't be that hot
The oil in the lines won't be anywhere near that temperature, but if it's 50/50 it won't be as bad.
Definitely test the return, I wouldn't be suprised if you're only 100 degrees or less.

350SD in Las Vegas on WVO - 115F - HOT FUN IN THE SUMMERTIME!
Hi folks,
I'm running my 350SD in Las Vegas on 50/50 filtered WVO and B5 BioDiesel mixture - the summer heat here tops out around 110-115 daily with street temps above 125... I've been running straight into the tank and the Benz runs WAY smoother on the mixture than on straight diesel/biodiesel... I do add a little Cetane Boost to help clean up the injectors, but that's it. I'm planning to add a GreaseCar WVO conversion ASAP because I have one on my 2001 VW Beetle and it runs like a top on 100% heated/filtered WVO... Any thoughts/advice, especially about the rough idle? P.S. I love these forums - TONS of great info, years of experienced MB drivers, and LOTS of very amusing characters!! Keep it up fellas!! |

From what ive seen and read on the greasecar forum is that the GC kit only heats in the veggie tank via coolent. Well just heating with coolent isnt enough to get it to 170F (which is the temp the wvo should be) so i would add a vegtherm or build a glowplug heater to get it to 170+. If you build a glowplug heater it would get the temp up to 170F in just 2 mins! They are pretty cheap to make, about $60 http://smallglowplugheater.blogspot.com/2005/12/small-glow-plug-heater.html

My car actually started quicker (even down at 45-50degs) with a blend of diesel, sams club clear fry oil, and regular gas, than on regular diesel....nice and quiet too.
The clear fry oil got cloudy around 30degrees....if diesel goes over 3.15 a gallon around here then I'll start using it....otherwise, my rewards card keeps diesel the best deal. I only pay about $2.80 a gallon right now with it. 2.92 at the truck stop, and my card gets me about 10-12 cents off per gallon. Sams oil works out to about 3.04 a gallon
