Yeah, a 5 ton would be nicer for power and the newer trucks have automatics. I like the multifuel engines in both of the older trucks because of their versatility, plus that's what I worked on in the service when I was a diesel specialist. I don't mind that the power rating is about the same as this bus currently has. The thing is I have 3 deuces and no 5 ton trucks. I'm not willing to drive a 5 ton back to Oregon from southern California so I've got what they sell more locally.
; Yeah, I've read about rust all through your fuel system if you don't take care of the water. In the long term it would certainly be worth it to get a larger and obviously more expensive centrifuge and they take an hour to process 55 gallons. I've been trying to think of a farm boy way to process oil, but I guess that's what you're doing by letting it settle for long periods of time.
Do you remember those toilet paper oil filters people were using on their cars back in the 80s? They say those were marvelous on vehicles and you didn't have to change your engine oil because it was so clean, so I think they ought to filter hot VO under gravity feed. Then again I'm sure someone somewhere has already tried that.
