on average tractor trailers receive 4-9 miles per gallon but it all depends on the truck, the engine set up, and the weight of the load that is being carried I have heard of some drivers carrying light loads with Ideal road conditions getting up to 14 MPG
it is the same
They are around $250,000.
You didn't specify which tunnel.
Tractor as classed as industrial machines and these use diesel fuel rather than petrol (gas)
There's a lot of variables to that question. For instance, how big of a tractor? Is it gas or diesel? And, what is it doing? Plowing would use considerably more fuel than cutting hay, for instance.
Horse trailers, tractor trailers, rail cars (train)
The number of tractor trailers that can be parked on 5 acres depends on parking layout and space utilization. A typical tractor trailer requires about 60 to 70 feet of length and 10 to 12 feet of width, which equates to approximately 0.15 to 0.2 acres per trailer when accounting for maneuvering space. Therefore, you could potentially park around 25 to 30 tractor trailers on 5 acres, assuming efficient use of space and proper layout.
You would use the same process that would be used on a regular passenger car. There isn't some sort of special paint or special painting method used on tractor-trailers.
Heavy machinery like tractors, air seeders, combine harvesters, augers, tractor trailers, cultivators, etc.
None. They use diesel fuel, which a North American tractor might hold up to 300 US gallons of (although 250, give or take, is a bit more common).
how much oil do i use when changing my oil in my bolen tractor 5.0 hp
Absolutely, and they're not the only ones who can. If you have a Qualcomm unit in your truck, you really can't afford to run inaccurate logs.
