We have a fuel prep on our 83 barth 8.2 detroit and i am satisfied with it. I can't honestly say that it has increased our torque or h.p. or even our fuel mileage as we put it on (as suggested by Les Hougland) shortly after buying our unit. What i can tell you about it is that we have had ZERO fuel problems with it in 4 1/2 years and that is buying fuel all over the country. (never know what you're really getting ie... how clean.)
As for the 8.2 if you are in a hurry in the mountains you better do an engine swap as it is going to slow down considerably if you are loaded as we usually are. When we first bought ours i thought i might be able to go up those BIG hills at 60+! He-He, ain't goin to happen. plan on slowing down to 45/50 and if it's a steep climb (as in hwy 101) we got down to about 25 mph going up it in northern Calif. This pulling the jeep and loaded as if fulltiming. If you keep your radiator clean, oil changed, good fuel, and mechanics up to date and can accept that you aren't going to set any land speed records with the 8.2 it wil give you good service. DO NOT EVER-EVER let this baby get too HOT! We also put in king cruise control and wouldn't be without it. also you'll need to find the sweet spot for the rpm's if you haven't yet. Ours seem to be around 2750/2800 running at 65/66 mph, down shift at about 2400 rmp.
Our mileage has ranged from 7.8 to 10.2 mpg with our unit. I think i would buy the fuel prep again as it is a good measure of clean fuel for me. other opinions may vary of course. In your position i would call Les and talk to him about the addition of the prep. Call the company also and talk to them about it. Ask Me or others any questions you have and then make your decision based on YOUR needs IF you think it will do what you want it to. Barth Rocks and 8.2 isn't that bad!
