I have a old friend that is so tight he squeaks when he walks. LOL Some other friend of his has been giving him old French fry grease/oil. He has been blending it with his farm diesel and running it in his tractors. I am not sure the ratio as he will not own up to how much he has been mixing in. I am willing to bet way too high of a percentage.
Now the trouble. I just got done rebuilding/cleaning the THIRD injection pump of his over the last eighteen months. The first one had a bad dampening ring so I never really thought much about it going bad.
The second one kind of threw up some flags as the pump was in good shape inside but just gummed up. The pistons inside the head where stuck and would not come out against the cam ring. I had to soak it for over a day to get the gunk out of it.
So I told him to quit using his home brew in his tractors. Tried to get it through his head he was not "saving" anything with his old French fry grease/oil. The few gallons he would have been replacing/saving of diesel fuel would not even buy the parts for the first injection pump.
I was doing this as a favor to him as he give me fresh garden produce all summer long. So I just was having him pay for the parts.
This time I told him it was going to be full boat just like I would charge everyone else. He complained. I told him if he wanted to check around to see if he could get it done cheaper elsewhere he was welcome too. He soon found out what the "real" cost of an injection pump rebuild is.
So he brought the tractor to me yesterday. I had him stand right by my side as I took the pump apart. I showed him all the fat/junk inside the pump. I had to boil it in mineral spirits to get all the stuff out of it. I have not found a parts/carb cleaner that will cut that grease/diesel combination very well.
I finished it up today. It runs fine. I "think" he realizes he was messing up his equipment.
Also I handed him back half of the money he thought the repair was going to cost him. I really was not going to charge him "full' price but I sure wanted to hit him with what it could cost him if he does not quit with his home brew.
So I would not be running old oils/grease in any tractors of mine. The few gallons you save will not cover the potential repair bills.
