As I have said before:
"Exxon XD-3 40wt is every bit as good as the Delo 100 and much easier to find.
I chuckle at those who think Delo 100 is some sort of magical elixir and they will go to the ends of the earth to get it. Delo 100 has reached some sort of overrated legendary status amongst the bus nut group. But, if it gives them warm fuzzies as they pour it in, and thatís what they like, then thatís OK."
what is the going rate per gallon? I don't have a problem switching from 100 to whatever. Since it fits the ash requirement the almighty dollar will be the decider. I now have an oil distribuotr that can order 100 for $11 and some change if my memory is ok this morning.
