Results of ECU reset and other for feul economy

no, face/feet shouldn't turn the compressor on. I was under the impression that it only turns it on for feet/windshield and windshield, and maybe for just feet too.
 
I get 550-625kms in my MSP in Calgary, and I warm my car up for 5 minutes when its cold.

Try using the block heater when its really cold out, my car starts up like a summer day if I plug it in for 30 minutes before.

That's how all my previous cars have been. It'll turn itself on for defrosting, windshield or feet/windshield, but never for feet or feet/face. The P5 seems to on feet, and I think feet/face. I'll have to play around with it and see what does what..

I think it's in the manual, I know I've read it somewhere. i think that only the FACE setting disables the compressor. I just filled-up my tank today. The final result... I drove 380 Km on 46 litres of gas. That's 236 miles on 12.15 Gal. That's 19 mpg. To answer a previous question, I drive mostly highway (like 70%) and try to use cruise control when I can. I'll be ordering those plugs you suggested real soon...
 
I just filled-up at a different station today. It actually cost me about 4 cents per litre more than most stations. We'll see if there's fewer additives there...
 
Yeah, 360km is pretty crappy mileage, even if it's an improvement. Personally according to the mileage I've gotten in the past, I consider it good mileage when I've got 520km at refuel time. Usually that translates to about 28-29 mpg for me.
 
i normally get about 500-550 km per tank in the summer, which drops to about 450-500 per tank if it's -25C or colder for a stretch, when i tend to let my car idle a little longer (about 5-7 min) than normal to warm up. i drive 90% city with a little freeway and/or highway on occasion.

definitely try different spark plugs; if that doesn't fix your really bad consumption, i would suggest a trip to the shop to see if it's something deeper that's causing your problem because 19 mpg is NOT normal for the P5.
 
Yeah, I hear you guys. 500+ Km is awesome. Even spoke with my brother-in-law tonight about what it could be. I just wish there was something definitive. One think he's not sure of that I came across last night are the spark plug wires. When I replaced mine last year, I got 2 wires. I found on a site last night a company selling those same 2 wires PLUS 2 other boots and 2 long springs. Are these to replace whatever is underneath our coil packs or what? Don't I have to buy a coil pack seperately or can I just replace the boots on them??
 
do the two wires already have the long boot things on them? If so, then yeah, sounds like they are replacing the ones on the stock coils (didn't even realize you could remove that from the stock coil packs.
 
Kansei, I had my friend (mechanic) look-up those sparkplug numbers you gave me and I realize I may have over-looked possible the largest factor in gas mileage differences...engine size. The plugs you mentioned are for a 1.6L engine. I own a 2L engine and I believe there's a 1.8L as well. Can there really be a 200km difference in miles per tank between these 2 sizes? Does the P5 rating of 30MPG only apply to a 1.6L engine or any model?? Sorry if it's a noob question.... And THANKS!
 
there's nothing other than a 2.0 Protege5. Yeah, I know the ZFR5F-11 isn't the OEM plug the mazda manual tells you to use but it works wonderfully and more smoothly than the BKR5F-11 stock plug. The only difference is that it is a long reach plug.
 
I have those plugs & 2.0l & auto & AC & can pull upper 20s easy if I keep it reasonable on the crazy driving habit scale. Car loves them. They just aren't spec'd on our cars in US.

Hey there....I just tracked down those ZFR5F-11 plugs...I was gonna put in NGK V-power, but those other ones sound pretty good. A longer spark plug is fine then in our cars??

Let me know since I can get them today:P Does climate affect what spark plugs work better? I am in NS and it does get quite cold here...just curious.
 
the ZFR5F-11 plugs I used were v-power, the v-power is just a standard copper plug with a little v cut in it though. the stores here don't carry any NGK plug cheaper than the v-power ones, weird.

The ZFR5F-11 will be fine in NS, I'm in a cold place too, it's no problem.

So these plugs are a big improvement then over the regular sized plugs? I guess I am just wondering how big of a difference putting new longer ones in would be compared to putting normal sized ones in. I don;t know too much about cars (yet) so I am pretty curious when it comes to "why"...:P (I'm a scientist..It's my nature!)

So you recommend these longer plugs.....What was the improvement when you switched to them?
 
It smoothed the idle as well as making it less jerky in reverse?

I can't find the thread for it right now but the long reach plugs (ZFR instead of BKR) are the plugs the car has from the factory when sold in Japan, I'm not really sure why they didn't in North America.
 
i get 700 nautical miles per tank. :P


No really, i'll fill up my tank and post what a protege 2.0 gets in a tropical weather.
