There is no such thing as a reliable waste vegetable oil conversion.
I’ve been around a number of them, built and rebuilt 7.3 and 12 valve Cummins injectors for guys running WVO, and there is NO WAY that you would EVER convince me to try that with any engine, much less a new(ish) common rail injection system.
What zeb said. I have dealt with a few of them, mostly on idi trucks. I remember one off hand that was in the shop 4 times in 3 months with a plugged injection pump. After the 4th time, his wife okayed me to return the truck to stock, so he could only run diesel.
Those p umps have a **** ton more leeway in them than a new hpfp, so I wouldnt even try it. It says b20 max on the door for a reason...
