When it is not steep downhill and you don't need to brake the car to slow it down, coasting down around 55 mph at idling gives the engine a rest also save gas. Just not sure if the vacuum and other stuff are operating at normal level

NO, not really, I'm usually speeding up during down hills especially if there is an up hill coming up, then I ease off the throttle going up hill.

When traffic conditions permit I nail each down-grade as a momentum extender with my econo vehicle, the tach. reads back to near 800 RPMs, tranny temps drop, torque loads drop also along with drivetrain loads.

Over time my mileage shows improvement, so I quit checking it, I spend on the average of $15.00 into my fuel tank, every 10 days, depends on week-end activities/extra driving. Roughly $45.00 for regular @ 1/2 tank or near that, sometimes top off when price drops down,= Monthly expense except for utility gas for home use, that's extra.

I tried that years ago with no benefit. I think it's just a placebo. I've read that modern cars have mechanisms designed to keep the engine moving while in neutral, and the gas usage from that defeats any benefit you might gain from coasting because the engine normally uses the car's momentum to avoid stalling when your foot is off the gas pedal.

Sustaining momentum is not for just anyone, becomes a bigger problem as far as to save fuel when driving. Vehicles are designed to slow to nearly a stop when the go pedal is released, and most like to apply the brakes, for security reasons(feel safer) when stopped. Some Drivers anyway.....

I once had a driver say to an officer "Yes! I was parked, My Vehicle in Park mode, My Foot on my Brake Peddle and My Parking Brake set, also"! "Wile reading He BUMPED into ME!!!.....

I then asked, would you(Officer) Please repeat what She just said, then I asked >> Just what normal person does that, when they are illegally parked, on absolute lever ground behind another vehicle, instead of at the proper marked designated marked parking spaces, right here? He then answered "She does, and DID!.... CRUNCH!!! IDLE CRUNCH.... FUEL $$~~~~gone.

Not today, maybe a traffic decell.. if on a slight down-grade, often happens, no danger(preparing to slow) for a common traffic movement. Now if I was a "Lap-looker" in motion watch out! Anybody I still steer strait unless I hit a bump, Your safe, my Wife won't let me text on her $ and I don't own a G...Cart as yet, FUN, FUN later!

Every manual car in the world goes into neutral when you pull to a stop, is that dangerous? If not, what makes putting the clutch to the floor dangerous? Folks should really think before posting.

Never up-hill, dangerous, even in 4X4 mode, pulled over can be a warning to get the vehicles front suspension checked. My Step-Grandson's car hade a swing arm bushing wore out(yanking his steering stability sideways during turns. About a $100. fix then GONE! POJ getting Worse....every mile!

It was easy on gas, still not affordable, many repair $$$ needed. "I Hinted.... Junk It"! He did....

No. You can still get pulled over in neutral and dangerous.

I'm just trying to remind some drivers that there is a possibility that to better their mileage savings at the refuel pumps, often a few bad habits need to change toward good ones.

Not serous habits but wasteful ones, most get ignored, the fast pace of life does that when in the drivers seat, and traffic conditions adds to that also. Habits like paying more attention to tire inflation first, with good weather permitting>>> then doing routine mirror/seat adjustment, Human vanity corrections, whatever ETC. even selecting the program for audio/entertainment, and buckling up all before starting the engine.

Remembering any downgrades are then better areas to reaccelerate your speed back to normal when possible, instead of using upgrades(terrain)in order to regain cruise travel speed without impeding other traffic.

Neutral mode while on level surfaces while waiting for a longer red light saves me fuel when driving the econo four cylinder, other size engines/vehicles may not respond to any savings doing that. It's not an instant savings habit, but works for me over a time interval, say three refueling and I normally only do a 1/2 tank each time, then if prices drop I top off all vehicles. Mowers and utility Stuff... Wife...& with(good Ice Cream)!
