So to get to my girlfriend there is a hill, going up i always DWL, but going down it always bothered me i would waste so much gas for no reason. Seeing as i have a 5-speed auto i always hesitated to turn off the car while in drive, i didn't think it would start in drive.

Being ambitious i figured out a way. After i would get over the apex of the hill, i would change gears to neutral and turn it off, i would coast all the way down, actually accelerating 7 mphs, coming to the point when i need power i turn on the car in neutral and change it to drive, i give it 3-4 seconds so the transmission adjusts.

The biggest thing i was afraid of was would the auto get into gear properly at speed. I'm doing this at 45mph tops. So far it seems great.

Another thing i do is turn off the engine at long traffic lights. But another thing that bothers me is am i killing the starter? or alternator? Must be something.

Anyways, thanks guys, just wanted to give some info for other people with autos. BTW, its a 2006 Civic ex coupe. my best tank has been 41mpg so far, its a 1.8L.:flag:

Hi Armavir:

___Yes, you always want to drop her back into N before FAS’ing. A little something you may find useful … When you restart the ICE, the tach will jump up on re-ignition. Honda’s are very well controlled here so you would normally see a 1,500 - 1,550 RPM peak. You want to attempt to reengage the Auto as the tach falls through a REV match point. Let us say at 45 mph, your Civic is running a normal 1,450 RPM. You reignite the ICE and almost immediately after she peaks at 1,500 RPM, you re-engage so as to Rev match. You will reduce wear and tear on your Auto then forcing it in from idle at a speed above a crawl.

___You are not killing the starter or the alternator but you are touching the 12V a little harder then most. My OEM is still in the garage and is well into its OEM cap but when FAS’ing long distances at night with lights, her V will drop out quickly. The Accord now has a D35 Yellow Top Optima for this exact reason. With a brand new Civic, I would not worry about it this year but next year you might depending on the amount of times you shut her down while driving. The Accord has seen maybe 15 - 17,500 shut downs and re-ignitions in her almost 70,000 miles with no ill effects although I do watch the 12V voltage w/ my SG-II as a reminder for just how far I can go ICE-Off. With the Optima D35, it is unlimited but with the smallish OEM 51R, it was about 4 long MS P&G’s at night w/ lights over ~ 2 miles and the OEM’s V was down in the 11.6 range. At that point, I was flirting with the inability to reignite the Accord afterwards.

___Finally, the Accord w/ Auto can be ground towed in N from my reads so its Auto can handle a FAS. I have not read up on the 8th gen Civic w/ Auto’s capabilities but if it can, you have little to worry about other then making sure you Rev match at each and every re-ignition and re-engagement.

___Good Luck

Ok, that relieves me alot!

Hi Armavir:

___Don’t get crazy and blame me when parts start falling out of the bottom of her tranny housing while re-engaging at 60 + mph however :D

If you are just starting to FAS make sure you familiarize your self with the lack of power brakes while the engine is off.

Hi Tom:

___After a few uses ;)

yea, the wheel gets real stiff and i can only get out a few pumps from the brake.

I haven't cut the 5AT in our Accord one bit of slack. I start the engine and dump it in Drive. No rev matching, no waiting. It engagues just like a shift... heck better. The electronic control is very good.

For me: so far, so good with FAS-ing the automatic Integra. About 130K on the odo and the tranny seems to be (knocking on wood) doing just fine after about 30K of NICE-On and OFF coasting. The trick is to rev match and not get too excited to get it back into gear. The car's still on it's 2nd battery, but I can foresee a new one in the next couple months.

BTW, Xcel, how's the new battery??? I've been on VAC for a while and I'm catching up on posts...

Hi RH77:

___Welcome back! The Optima is tough. I have been through the warm up P&G route after 16 miles over 45 minutes at night and the lowest Voltage shown was 11. Volts. The OEM was shot after the fourth cycle not 2 miles in which forced a NICE-On for two cycles before I could run another 4 in a pure P&G w/ FAS’.

___Good Luck
