Official Thread for posting daily FE updates

OK, some of you asked for this, so I started a new thread for all of us to use. So here we go!

Great way to start out a new tank!

I was dreading the drive in this morning because it was dark and raining. Both FE killers due to wipers and lights on and increased rolling resistance from tires pushing water out of the way and spraying it all over. Temp was 45F. Last night I indexed my plugs and decided on a modified route to work that would cut out some FE killer lights (when I miss them). So I count 3 variables that have changed for this mornings trip, rain, indexed plugs and a new route.

Well right out of the box (garage) I noticed a difference in FE. By the time I get to the main road, about 0.2 km into my trip, my FE was 19 MPG where usually it was 16.5. Then I began the new segment of my route. Eventually when the new segment merged into the original route at about the 10 km mark, I noticed that I was about 6.5 MPG higher than my previous best to that point. At the 20 km point I was at 6.7 MPG higher, or 74.8 MPG! At this point I am at the low point of my commute so don't get too excited im telling myself. Now the merge onto I-79 and I duck in behind a fuel tanker and draft at 55 MPH, ASI showing 20-30 MPH. At the 30 km mark I am exiting I-79 and am at the high point of the commute, 61.9 MPG. The final 10 km leg has 10 stoplights and I made 5 of them. I cruised into the parking lot at 63.68 MPG which beats the old record of 62.75! The trip length is slightly shorter so the total fuel used was .384 gallons beating the previous record of .392.

So I'm sitting here wondering, WTF? It was raining, which in my experience is detrimental to FE and wind wasn't really a factor. On the downhill ign off segments, speeds seemed to be better than normal. Usually I take a hairpin curve, engine off and exit at about 35 MPH and coast for a mile or so to a 25 MPH speed limit sign at about 27 MPH. Today I took the curve slower, exiting at 32MPH and was still at 30MPH when I got to the 25 MPH sign. ASI showed same as the speedo so no tail wind.

I have heard some Prius and Insight drivers say that they notice an increase in FE with very light rain but could never prove it definitively. I can't prove anything at this point but what i know for sure is that starting a new tank this way is very satisfying. Mehbe the indexing helped? Mehbe the new route? We shall see on Monday which is supposed to be cooler but dry. Thunderstorms and wind for tonights drive, but 63F too. Maybe I will be surprised again?

Oh man I wish I could turn off the DRLs that easily in my Passat.

On another note, I drove it on a short round-trip last night (about 1 hr, 45 min). I averaged 34.3 mpg out and 39.7 back (loaded up with about 250 lb of stuff and the AC on part of the way). That's a personal best for me with that car. I'm almost up to 2 x EPA (21). I really do have to quit driving on those snow tires though.

MetroMPG has some sort of switch rigged to turn off his. My handbrake-switch was/is a Metro-only feature I think.

2x EPA? Nice!

My hand brake is too new to use the "one-click" method - it puts the brakes on slightly, even with a slight pull. So I added a switch in the circuit that turns the parking brake dash light on (that circuit controls our DRLs).

I use my headlights during the day more selectively now. In some urban & highway settings, depending mainly on the amount of traffic, I run with lights. But probably more than half the time they're off.

DRL must be a canada thing ay - some cars have them but only a few types VW and Volvo I think. 120 watts is not too much power. Maybe some secondary bulbs with lower wattage or LEDs!

[MetroMPG]

GM does it on all models in the US also. I've been mulling over the idea of setting up a single bright LED that I could leave on all the time.

The handbrake on my Saturn is too new also. I once saw a diagram that showed how to disable them but I can't seem to find it now. I remember that it was fairly simple and basiclly involved a jumper wire where a relay goes. Has anyone else heard of this?

[SVOboy]

DRLs are mandatory in Canada for safety reasons. Toyotas don't have them in the US but Hondas do because Honda is too smart to make different cars for the US/Canada. Anyway, you get money off on your insurance if you have DRLs.

My dad saved so much money on his insurance by switiching from an old car to a new accord. He lowered his insurance payments by $20 a month. The new accord has 8 air bags, ABS, lo jack, alarm and probably other stuff.

I don't know if he has DRL, but he's still saving a bundle.

I saved money by having a good gpa and driving a car not worth enough to get comprehensive on,
