Diesel Dos And Don'ts
I own an '06 Ford F-350 with the 6L diesel. Will off-road fuel usage damage the engine mechanically in any way?

We're not exactly sure what you mean by off-road fuel, but we're guessing it might be diesel fuel used in farm machinery or nonhighway vehicles. The difference may be as simple as one fuel pays road taxes and one doesn't. Skipping the ethics of not paying your share of road taxes, the key issue regarding your truck is whether the formulation is the same as what Ford recommends for your engine. Your owner's manual should state fuel requirements. Contact the supplier of the off-road fuel and ask if its fuel is the same as what you can buy at a regular gas station.

If it was our truck, we wouldn't use anything but top-quality diesel unless we were stranded in Baja and had to use whatever fuel was at hand to outrun Pancho Villa. Harming almost anything in your diesel's fuel system will easily cost more to repair than any savings from running substandard fuel.

Yeah, We Love That Truck Too
Hey guys, I've read your mag off and on and I love some of the trucks you feature. For instance, the truck on the cover of your July '08 issue, the F-350, is awesome! I'm more of a Chevy guy, so the red Suburban with the 49-inch Swampers is frickin' sweet! But what I really wanted to say is the truck on page 119 of that issue is one of my favorites. Maybe, you can do that truck as a feature. The paint and detail are amazing! I just wanted to say your mag is awesome and keep up the good work. Someday I might be in the mag!

Thanks, Kevin, but there are four different trucks on page 119 of the July issue. We love 'em all. Which one were you talking about?

I have a show truck that I do not take out of the garage in winter (it is being stored). I have had different people give me different answers and I would like to know your answer. I will be placing my truck on floor jacks during winter. Where should the floor jacks for the rear axle be placed? Should they go near the tires (outward), near the ball (inward), or in the middle between the ball and wheels?

I receive several truck magazines and Sport Truck is tops! That is why I am asking you and not anyone else.

We're going to assume that by floor jacks you mean jackstands because even the best floor jacks tend to leak down over time and that would result in your truck sitting crooked over the course of a winter storage period. The procedure for storing your truck in the air is different if you have airbags rather than coil springs on your truck. If you're truck rides on air, then you need to not only support the chassis via jackstands at all four corners but also the rear axle and front control arms. This will prevent the airbags from overextending and pulling apart at the upper and lower mounting plates. If your truck rides on coil springs, this is not a concern and you can simply support the chassis up front and rear. It sounds like you'd like to support the rear axle as well, and if that's the case then we recommend placing the jackstands centered between the differential and wheels. Because the chassis is also supported, there's little weight on the axletubes aside from the weight of the wheels and the axle itself, so you don't need to worry about bending the tubes.
