Noob questions about pulse and glide

makes sense. I've only been P&G'ing for one tank so far. Got a lot to learn

Everything is situational. Your car, roads and driving conditions are unique. The things you'll learn are transferrable, but if you change your route you'll have a lot to learn. Even the traffic conditions at different times will give you things to learn. After years in the Aveo you'll have to learn your next car too.

Get a ScanGauge or UltraGauge. Being able to see short trip (since startup) and long trip (reset every fill up) mpg, as well as a few other things that you may find helpful will help you see what's going on and learn a lot.

And welcome to the fun!

not sure I completely understand the scangauge. I've been looking at them, but how do you hook it up to your car? I have two ports, one under the steering column and another under my glove box.

I don't have an SG or an Aveo. Haven't learned them yet.

Aveo, I don't think you will be ever using (able to get car to go into) DFCO if you are driving where there is a speed bump every 200-300 meters.

The biggest gains in fuel economy will be driving habits. It becoms second nature after a while. Poke around this classic blog for ideas on saving a bunch of gas..

btw..ac and pulse n glide? You should hate ac just as much as satin and brakin' if you are hyper-miling

I don't slow for speed bumps. It's my way of telling The Man that he can wear down my suspension components, but he can never take my freedom.

Speed bumps should be illegal.

I have a question (okay a few questions) for you guys that EOC for your glide. How do you start back up? Do you pop the clutch or use the starter? Either way, doesn't that wear out components faster? Honest question, not being a troll. I tried EOC a few times and restarted with the clutch but I keep thinking I'm going to take out the clutch over time. I've been trying to play around a bit with EOnC coast. I think it helps a little but not a lot. Now almost all my driving is in heavy city traffic, mostly with a cold engine. I'm not doing the 80% load with a cold engine and I usually just get up to speed and I have to stop anyway. Is P&G even a technique that works in town?

If you just drop it into gear, you will wreck components. If you just touch the clutch plate to the flywheel--hardly even feeling the contact a lot of the time--you will not wear out components. For proof all I have is my car. It has the original 1998 Honda clutch, I know because I bought it from a dealer in Virignia, certified used, in 2001. The car now has almost 250k miles on it. Same clutch. I have been bump starting it using 5th, 4th, 3rd, and sometimes even 2cd gear maybe 50 or 60 times a day minimum every day of the week for 5.5 years and about 75k or 80k miles. Still drives great.

Using the starter. Since I shut down at all significant stops (not stop signs), I also use the starter a lot. 20 times a day maybe? Still using the 1998 starter motor.

It just keep going, and going, and going....

Thanks, personal experience is good. This is my first manual trans daily driver in over 20 years. Just driving it normally I'm not as smooth as I used to be when I was a kid lol. getting better though. can't really eoc now anyway cause it's always dark and it sometimes doesn't even get warm enough to open the thermostat with the cold, but I may give it a try again when the weather improves.

[Fat Charlie]

Yeah, the north winter isn't EOC weather.

Like California98Civic was saying, there's a big difference between bump starting and popping the clutch. If you can engage the disc brakes smoothly, I'm sure you'll be working the clutch just fine in no time.

Get yourself an SG or UG and you'll see how much gliding (on or off) works, the difference is incredible. In town is made for P&G: you just said that you get up to speed and have to stop, you just need to work it to your advantage. Decelerating in gear puts you in DFCO. Dropping into neutral lets you keep going, slowing a bit, at maybe a couple hundred mpg (that's where the gauges come in). Working with any slight hills can help you maximize this.

I do some horrible bumper to bumper traffic. Yes, working a clutch is a lot of work, but so is riding the brakes like everyone else is doing. But by tapping myself along I'm burning a lot less gas and not wearing my brakes at all, and by doing it well I'm not wearing the clutch either- my last car lived and died on that commute and stood up to some serious thrashing before I came here, and it went away at 205k (207k? Don't remember exactly) miles with its original clutch.

Do you have your grille blocked? That works wonders with warmup time.
