Do you have a way of testing for water in your WVO?
Also, have you read anything about acrolein and wvo exhaust?

I have not read of acrlien. And I have done the stove fry test for water in my oil once, but it was pointless to do it twice. I always have let my oil separate in clear cubies in the heat for several weeks to see how things settle out and then I just got to know what good oil looks like from the start. And then heed it – I don’t take ad grease.
You haven’t given me much info, but I assume you are experiencing loss of power during city driving? Don’t know what your symptoms are or what fuel you are running or what conversion you did if any or what year car you have. But loss of power, assuming that’s your symptom, I’d start trouble shooting in a Benz older than 1986 by looking for hindrance in fuel delivery: change fuel filter, check fuel lines for kinks, clean injectors, replace fuel lines if necessary, drop tank and clean I out. If fuel delivery is the issue, then checking all those things should reveal where to go next. For example, you might see crusties from poor waste veggie oil selection in the lines meaning be more selective about the grease you’re getting. Or you may find a full on algae bloom like I did, in your tank (that issue was accompanied by smoking eventually). But in newer cars there are oodles of sensors that can get confused and scre with the air mixture for example and reduce power too. Your fuel pump takes a lot of strain over running a thick fuel like WVO and that could be going at some point too.
PS – if u do ever choose to replace fuel lines a highly recommend clear line especially around the filter, pump, injectors so you can see through it in the future to locate fuel quality or obstructions rather than having to guess and take them all off.
