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?

Big trucks don't have to have a blow-out, they may just try to straddle debris in their lane path which regularly falls from trailers or other vehicles, objects that can be metal, then cast up ward and rearward by the velocity forces.

Why does anyone think that officials over a race track make sure all debris is cleared in order to resume racing? Unknown debris can be very deadly run over at highway speeds. Besides semis can't swerve do to their heavy loads, being more top heavy, wind forces are strong sometimes or wet pavement conditions hamper maneuverability. Close or Too Close is Bad BAD!

I avoid drafting but sometimes during rush hour in heavy traffic some vehicles cut in front my vehicle with very little space such that my car ends up drafting behind them until I can wiggle in some distance between them and me ... The Prius is one of the most aerodynamic vehicles on the road so drafting doesn't seem to help that much unless the Prius is going over 60 mph

Getting 2 car lengths behind a truck at highway speeds is a good way to get a truck bumper in the face.

Yes, anytime you can reduce air resistance, your mileage will go up. But, that is extremely unsafe, and in many areas, against the law.

Not immediately behind them. Usually 5 car lengths at a minimum, further still is better to avoid rocks and other debris kicked up by the truck.

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.
