Andrew I see what you're mentioning about such a system being better for Trucks or Heavy machinery like tractors and such. I'm not in the position right now to be testing this sorta stuff on my primary vehicle. I would like to know more about the cutting of fuel WMO or other high viscosity fuel. The other thing I was considering was numerous articles I have read that seemed credible stated that gasoline engines can benefit from running small quantities of diesel and vice versa diesel engines supposedly can benefit from cutting with small quantities of gasoline. Has anyone read the same materials or studies?
Hi,
W85 (waste motor oil 85% (of course highly filtered or centrifuged/ dried ) cut with RUG 15% (regular unleaded gas) to approximate diesel fuel viscosity operates best (easiest) in more mechanical engines with looser tolerances.
You don't want to cut the waste motor oil with other high viscosity fuels because your overall goal is to make the relatively thick used motor oil approximate diesel viscosity so you have to cut it with things that will thin itout rather than keep as thick as it is starting out (RUG seems to be the cheapest commonly available item to do this and the 15% ratio is the typical starting point depending on how thick the oil you initially have is).
You can get fancy with flow gauges / tools and specific gravity tools to more accurately get the WMO to mimmic Diesel viscosity.
W85 can work in older diesel cars / trucks as well but I mainly mentioned using it in larger trucks and equipment since they drink far more fuel than our fuel sipping 50+ MPG TDI's so you would see a greater savings faster (back when I was operating box trucks for deliveries I was spending about $300 per day in fuel costs alone .... you can see how even saving 1/2 of that daily would add up quick!).
I have read that IDI engines seem more forgiving than DI engines of the W85.
I did not really get into it from a user standpoint because By the time I got everything set up I got out of the box trucking because the companies I ran through lost the contracts etc .... BUT there was money to be made because we were making some $$ off the trucking to start with .... saving the extra $$ up to whatever fuel we could replace by running W85 could have been pretty good $$ per day in just money NOT spent for fuel.
BTW if doing this , the W85 is a fuel additive/ fuel displacer that helps lube the engine (its motor oil after all !) NOT a fuel so no road tax etc .... Plus technically the RUG has already been taxed!
Of course some may come back and say burning oil is not allowable etc BUT back in the day some big trucks ran oil changers that basically routed old engine oil back into the fuel to be burned ... I cant recall the name of that system but it was made and installed on some big rigs ... aftermarket I believe.
