Man, what a beat-to-death topic.
Worry about things that might actually be worthy of worry.
No cop is gonna dip a pickup unless you’re known all over town for bragging about running red as OTR fuel.

It is very common for us, people get check for that all the time especially during the summer (they aren't as busy). I would assume it depends where you live and what is the industry surrounding your area... If its farms or the wood industry, and you have a diesel and look like you work for one or the other you are more likely to get check.

I’d be more interested in finding a high-quality fuel from a reputable company. I’ve almost never bought diesel anywhere but at Irving or Southern States. They both have 50 cetane, rather than 40 and Irving owns its own refineries. No additives necessary, year-round.

After 35 years of trucking, it has never happened to me and I don't think I have ever heard of anyone else having it happen. Maybe it's a state by state thing or a Canada thing?

I'm with Ortimber -- only difference is color and cost. I would be more concerned about whether your tractor can burn biodiesel. Kubota says don't ever burn bio.

And if I used farm fuel, it would only be from a place (farming community) where they sold a high volume. I sure want to avoid water and other problems with fuel. I use regular vehicle diesel (not bio).

I live in PA, which has one of the highest fuel tax rates in the US. Consequently, tank dipping is done more frequently here than it is in many other states. It's commonly done when diesel vehicles are stopped for other violations.

I burn coal for heat and the coal yard is just 2 miles down the highway. I have oil heat as a backup, and use red fuel from my storage tank in my tractors. To avoid the high coal delivery charge, every week or so, I would take the tractor down to the yard and buy a FEL bucket full.

A couple of years ago, I was stopped by a PA state trooper who saw me doing this on a regular basis. He told me hauling coal was not considered farm use and threatened to dip my tractor tank the next time he caught me. Rather than risk the heavy fine, I now have the coal delivered.

I’ve seen it done in Illinois also. Only a couple times I can think of. Once was during harvest at an elevator where farmers were off loading.

Wow. All I can say.

I guess your state is free from any real crime that could be addressed by the state police.

Now I will admit, I don't know a darn thing about diesel fuels. Never touched a diesel motor, much less owned one before I bought my tractor several months ago. A friend of mine told me to use the off road diesel, since it is significantly cheaper, and basically the same as the on road stuff you would buy for passenger vehicles except for the colored dye to mark the off road stuff.

Then the other day another friend tells me that I shouldn't be using the off road diesel in my tractor, because there are significant deficiencies in the off road stuff, particularly lubrication of engine parts, that are detrimental to the engine.

So, who is correct?

And I sure do hope that there isn't going to be 50 percent saying one, and the other 50 percent saying the other is correct. :/
only thing I have seen is the on road & off road diesel fuels are the same except the off road has a dye in it, this tells DOT if you are using off road diesel in a licenced transportation vehicle this can get you into a lot of trouble if they suspect and check your fuel because of no road tax on off road diesel

I agree, but the state police barracks is on the same highway, just a few miles away. Troopers are always coming & going. I guess I just annoyed one of them.

A couple of you guys mentioned using your home heating oil in your tractors. Just as everything else, a couple people told me it's the same stuff with dye; a couple people told me it's very different.
I do it to save some money, but especially for convienience. I put a pump on top of my home heating tank, and it saves a lot of lifting and filling jugs.
Is it the same fuel or not?

Off road diesel is dyed red so that it shows up in the exhaust if you use it in an on road vehicle. The reason is the off road diesel has no road tax on it. Other than that it is usually the same as the on road stuff.

On and off road diesel are exactly identical except for the red dye. Most places the off road is significantly cheaper but that depends on how your state taxes fuel.

Interesting! Here in Canada we have farm diesel it is dyed kinda purple. Really same diesel except for the dye and less tax! We can use it in our trucks on road (registered as farm trucks).

Random check points are perfectly legal everywhere if public safety is the issue. The difference in price of the two fuels is road tax and greed on the retailer's part. Stay legal and get over it.

I don't know if the two are chemically identical, but I've been using it in my tractors for over 40 years now and haven't had any issues.

Ultra low sulfur fuels are required for most newer tractors. ULS fuel was required for on road use well before the same requirement was applied to home heating oil. Now, almost all fuels, clear or red, are ULS, according to my heating oil supplier.

Here in Michigan there is no road use tax on offroad diesel so it's usually 30-40 cents cheaper than on road. Just like propane. If you use propane to dry down your crops, there is no state tax on it. Only on residential use.

I own outright 3, 500 gallon propane tanks and one is for crop drying. My suppler has differentiate between my household propane usage and my dry down propane and after all these years, he know the difference.

I believe in Illinois it’s not regular state police that are dipping tanks but some unit that is assigned to that.

Ag use and off road fuel has a dye to signify that it isn’t taxed for road use. That’s the difference for me. As for using fuel oil for a tractor why take the chance?
