Hi folks,

Well, since I started this thread, my brother-in law has picked up a W123 and is currently blending WVO and RUG at a 80/20 ratio (80% WVO to 20% RUG) He is using it single tank and reports good results for the last 2500 miles.

However, he lives in Michigan and even though the 20% RUG thins the WVO out somewhat, he told me he is a little concerned about starting the car and running it with a cold fuel blend in the Michigan winter.

Now the question....He told me he wants to use electrically controlled injection line heaters (I'm guessing Fattywagon heaters) to heat the fuel lines and keep the fuel warm and thin in the cold months, but wonders if heating the injection lines to about 200-300 degrees would cause the RUG in the blend to vapor lock.

My response to him is that the ration of RUG to WVO is low so that it most likely would not be an issue, but I thought I would ask here anyway to get some opinions and discussion going. So.....what do you think??
