Snake oil?

[hayjayhorses]

my dad is anal about MPG last year I gave him a 1 gallon jug of Walmart 2 stoke he ran it about 265:1 ratio (just like he ran Lucas). With Lucas he got almost 10% better fuel mileage and a little better than 10% with the 2 stroke oil and the 2stroke is 9 bucks a gallon vs. Lucas at $22 ish.
This is in his '99 F450


I run it off and on in every thing, my Russian made Ledda 35 (basically a Belarus 310) , 35hp air cooler 2 cylinder diesel, likes the two stroke, I think it make a huge difference, especially when running pump fuel, the same results with my 1750 Case uniloader

my mechanical Cat 3116 did like 15% better on 2 stoke an made a little more boost

also have an '86 6.9 that had more git up and go with 2 stroke.
