I have noticed that my mpg goes up when I am behind a truck or other larger vehicle at higher speeds, even with a distance of about 2 car lengths between; I have an instant mpg gauge on my Honda hybrid. I try not to get too close, and am a bit wary of a truck tire blowout, but like the increase in mpg. Have you noticed this as well?
How often do you draft?

How about a titanium telescopic tow hitch with a electric magnet mounted at the front(camouflaged) of course >Hint< (front mounted) and retractable, HMmmmmm.....

Trucks, several grouped do break up strong headwinds partially, but at a safe realized traveling distance, only a slight MPG. gain noticed. There is still the risk of road debris unseen. at legal following distances.

The only big advantage to following a large truck is it often discourages tailgaters. your tailgaters, except if they are right lane traveling exit'ers in waiting right on your butt with their signal on then to soon exit!

Two car lengths? You should hook a bar to the truck's back-end, turn off your engine & get a tow. Then, your mpg will really go up. Just make sure you unhook & drive away, when the truck comes to a stop, so the truck driver can't charge you a towing fee.

Too risky. The best way to avoid crashes with other vehicles is to keep plenty of space between you and everyone else.

please consider those around and the truck drivers safety when you think it is ok to save a few pennies and risk the life of someone else or yourself. If it could cause or create an accident, than one day it will. The truckers cannot see you in that blind spot too close behind them. If they have to suddenly stop, you and those in your vehicle could be killed. Do you really want to live with being responsible for killing others?

For any increase in mpg you have to be about less than 5 feet away - not worth it in terms of safety.

Yes, it works, but not worth it. Large vehicles spit a lot of raod debris & it can chip paint on the car. Not too safe to do either.

This was covered by Mythbusters. They established that the closer you are to a truck, the more efficient you will be in the truck's following vacuum. However, it doesn't become a significant savings until you are just a few feet behind the truck!

So the answer is: Yes--in theory, you save. But in reality, for you to save anything, you are VERY dangerously tailgating.

Good Morning Kinglemuel,

Enough has already been posted to inform you that drafting FOR ANY REASON is unsafe and could cause death, injury or property damage. Even experienced race car drivers know the risks on a "controlled" track.

One issue I have not read, and it is quite valid, is that "drafting" can cause your vehicle to overheat. When you intentionally draft someone, you're directing airflow around your vehicle not through the front as designed. In today's newer vehicles, the radiators are designed to be adequate in normal driving, thus any prolonged disruption of airflow will deprive air to the engine's cooling system. It will also cause the vehicle's computer system to compensate air/fuel mixtures, so where is the savings?

If for no other reason than safety, cease and desist this extremely dangerous method of driving! In all kindness, you don't have the skills to avert what could be a deadly accident and are causing risks to the driving public.

Take care :-). MGY

Not very smart your no bionic man to start with first and your reaction at highway speed will never save you fast enough. But their insurance will love you for it should you meet the back-end of their customers car.

"Higher speed 2 car lengths" "not too close" those two don't go together. Don't think that the very small mileage improvements is worth the risk.

I joke about catching wind from big rigs, but I never do it. I don't feel safe and it's not worth my life to save a few bucks, even a couple of hundred a year. I don't drive a lot, but even if I did, that is playing with fire.

drafting will in fact increase MPG. problem for me is I'd rather not risk debris and rocks being kicked up and chipping my paint or worse cracking the windshield in the name of saving a buck or two on gas.

You can notice the opposite effect when passing a truck. The wind movement around the front of the truck creates a sideways pushing effect as you pass a truck, even on a multiple lane highway.

Drafting is an art and those who are not proficient should abstain. Too many drivers today lack basic skills much less advanced proficiency.

That close at highway speeds will get you a chance for a multi pile-up, or a fat ticket from a rookie SPO ! Fuel costs would be cheaper, the tension/frown wrinkles, and then maybe spent lead is hard on radiators, but one might make some History, when at it.

Then there are the kooks out traveling also even during daytime hours and making daily Historical News....

Glad this post generated some good discussion and insights; as a result, I will make sure I keep a greater separation. I retrospect, I probably have been typically leaving about 100ft or more between, except briefly if traffic slows down until I can back off some. I try to make sure the driver ahead of me can see me in his mirror at least from time to time.

I avoid trucks carrying gravel or other debris. Recently I got behind a logging truck on a 2 lane road that I could not get around for 20 minutes.

Using the 2-second following distance, at 60 mph (88ft/s) you should be at least 176 ft behind the truck. Being that it is a truck, with a longer stopping distance than most cars, you might reduce be able to reduce that to 100 feet, but only if you never take your eyes off of the truck. That's a very tedious way to drive and not recommended for long periods. Any closer than 100 feet, you will be right up on the truck before you can react.

At 75 mph (110 ft/s) and 100 ft away, you'll be rear-ending the truck before you can hit the brakes. 2 car-lengths (40 ft)? That's plain suicidal.

Mythbusters found that following a semi at 100 feet can save up to 11% but not recommended. My opinion is that 100 feet is as close as I want to get a another vehicle at 70 mph - no closer.
