Sounds like the current owner has been experimenting with alternative fuels.

If this is the case, you should find out exactly what he has been doing. In the case of waste motor oil, he should be filtering it really well through a very fine filter. In other words, not an old gym sock.

I am not offhand familiar with how the guys on this site who do the WMO thing do it, but perhaps someone else can give specific info.

Also did he run it on 100 pct WMO or is he adding some to the tank on fillups, or a combo of WMO/RUG or?

Much the same for the vegoil.

Also in either case, if he hasn't being doing things 100 percent smart, find out how long he has been pushing lousy fuel through his injection pump, etc.
