Amen, i tried to point this out about 300 posts earlier. Which goes to prove that nobody actually reads anything on the internet
On the contrary, most people here get ALL their info on the internet - vs. living it like some of us.
There's far too many people posting erronous info on this board (as an example) for me take anything anybody says seriously.
All I can say for myself is I've got 20yrs under my belt as an ASE tech, and currently run a repair shop that's part of a much larger wholesale entity.
Do I have documentation to prove that excessive engine braking causes undue wear? Nope. Just my experiences over the years - and gut belief.
Believe what you will.

First of all, bullsh*t on engine braking straining componants. You might as well say that moving the car strains your wheel bearings so you should just leave the car sit. Or that opening the door strains your hinges so you should never open the doors to your car. I engine brake all the time and my last clutch lasted 150,000 miles. As long as the revs are matched, there's no meaningful wear on the clutch or drivetrain.
The point is not to outperform the brakes. You'd have to be a complete and utter moron to think that was the reason for engine braking. It's simply a way to bleed off speed gradually when you would otherwise only be barely touching the brakes. For example, when you're getting onto one freeway from another freeway you can either downshift from 5th to 4th and coast in gear around the exit loop or ride the brakes the whole way. The first is engine braking. Engine braking should NEVER be used to being the car to a stop.

As for cheap, I AM a cheapass and I can tell you that 15% is NOT below the cheapass line. 10% is standard IMHO
That's all I am pointing out... I respect the fact that you know you are a cheapass.
Altough the industry standard for even getting server outside your home is %15... I'll just fall back on my cheapass comment and leave it at that

******, I don't care if I'm a cheapass. Say what you will about my spending habits, but I think that first, not every service is worth 15%, cause most of it is mediocre, and second, 10% is a lot. How would you like to get taxed 10% on everything. NY is almost there, and they hate it. Imagine buying a 3000 TV and then getting charged 300 bucks on just taxes. Damn taxman, how about learning how to balance your budget?!
And where do you get off calling me a cheapass, you're a spoiled man with too much money up your ass. 15% may be the standard, but I don't like to conform.
I know you guys had 200+ pages of this recently, and somehow determined that coasting in neutral uses more gas than not, but any of the hypermilers will argue with you and show you real-world results.
Go to the hypermiler forum at TDIclub.com. They'll educate you in how to hypermile, and they'll show you their results. In fact, they use a website online to track their gas mileage at each fill up. Some of these guys compete in hypermiler competitions. I know one guy who's won it a few years in a row with an old Passat TDI that gets some ungodly gas mileage. They even use hilly routes so they can use them to coast. One guy ran in a competition and got over 100 mpg, severely beating everyone else, and he did so on a hilly route. However, he misunderstood the rules. He turned the engine off completely on downhill coasts. Some cars nowadays turn the engine off when coasting. But it wasn't allowed in that competition, so he was disqualified. According to some of the posts I read, "no fuel" is used when driving in gear without your foot on the gas in some vehicles. That would only be true on the cars that do engine shutdown when coasting in gear.
I've been able to pick up a few mpg just by coasting up to stop signs and lights and down hills (and sometimes up small ones). It works pretty well, but you don't pick up just a ton of MPG from it unless you're constantly doing it.
When a stick is in neutral, the car puts just enough gas into the engine to move the pistons. Nothing more. That's the tiniest amount of gas one can use. When it's in gear, driving down a hill, the engine still puts gas in the engine, but the engine is at a much higher RPM, so it uses more gas. It's very simple. With variable valve timing cars, at idle, the valves are barely opening, so the fuel usage is minimal. Same goes for driving down a hill in gear--it uses as little fuel as it can, but it's at a higher RPM, so it wastes more gas.
Personally, I don't care about saving money by hypermiling. But I used to have to pull high MPG numbers out of Jetta TDIs, so I'm pretty good at it. And it's just sad when there's misinformation out there.
If there's some magical way that cars don't use gas when coasting in gear, please enlighten me.
