Miles per Gallon MPG Inquiry

Has anyone done a MPG test on their stock 2011 Mazda 2? The Mazda web site as ~ 35 MPG, but I am getting better ~ 40. I was just wondering what other 2011 Mazda 2 owners were getting?
 
Hi John,

Thank you for sharing that with me.

Actually, I am really not sure I was getting ~ 40 because I didn't test it long enough, but I thought it was about that.

I would love to drive crazy as well, but around here N VA (DC area) there are cops everywhere and tickets are more painful than getting smacked in the mug. With 1/2 of one ticket I could purchase a Short Ram Intake from CorkSport.

Take care, Bruce
 
Hi Bruce,

I find it hard to get a good reading on a single tank of gas since the gas pumps want to kick off long before its filled. I don't think the "kick off" is consistant. I usually fill until I see gas up to the filler (Yes, I know, you're not supposed to do that<LOL>).

Probably need to keep a running tally for multiple tankfuls and average it. I'm not driven enough to do that myself.

John
 
I understand and agree John, what you said happens with me as well.

I am going on a long trip over Thanksgiving and will do a MPG test and post it herein.
 
Cool.

FWIW--I have a vague, un-documented, perception that the M2 responds to better gasoline (Shell, for example) and a slightly higher octane (say 89). Of course, I have not documented that with multiple fill-ups and my driving is very inconsistent so it would be difficult at best.

Let us know what you find.

John
 
Yes, I will let you know. Interesting point about the octane you speak about.

Also, I have done a lot of experimenting with MPG with my other car using high performance spark plugs, i.e., Plulstar and E3. Excellent plugs.

In my other cars I got ~ 2 to >4% better performance and MPG with them installed. I am actually doing this with my M2 as well -- interesting to see what happens.

Will keep you posted.

i was thinking of buying E3 for the 2. thoughts?

Yes, the factory plugs are excellent, but I wanted to see if I could get increased performance as well. I only have a little over 1K miles. E3's design exposes the spark directly in the middle (not blocked by the outer electrode) so less degradation the ignition cycle.
 
yup...check out my fuelly below, highest i've ever gotten was around 35.5 mpg, but i don't drive very nicely...i got 34 something MPG on a 200+ mile trip to san diego and back going up and down mountains doing 85-95 the whole way...so all things considered...i could prolly hit 40 mpg if i started to drive 65-70 mph all the time
 
The E3 gets horrible reviews on the LS1 sites. I use the Brisk plugs and when I had a Mini Cooper most ran those as well.

I use the LGS, but the Mini guys were having great success with the Silver.

No indexing, and the spark is completely exposed.

yeah e3 seems to get alot of hate. but thers always others
 
I have never heard of the LGS plug you show above -- which exact plug number do you use in the Mazda 2 2011 and have you seen any improvements?

I am now using the E3 in my Mazda 2 and they seem to be working great and I have been using them in my 2007 Yaris and they are outstanding in that car. Crazy, but what really made me like the E3s was in my lawn mower -- know that is crazy, but mowing my grass was hard because my mower bogged down constantly, but once I put the E3 plug in it noticeable helped and made a very big difference and now my mower essentially goes right through the tall grass. It was impressive. I am a pretty good mechanic and all around handy man and professional welder/metal fabricator so I do notice things...

What say you?

Thank you.

my friend needs to replace the plugs in his silverado so weve been researching plugs for his truck and my 2 and it seems E3 only get bad reviews for trucks and other 8 cyl cars. the small engine reviews seemgood. ill buy some and test them.
 
I like the E3s a lot and now use them in my 2 and Yaris. Funny, the factory 2 plugs are excellent, but I am seeking higher performance and believe the E3s perform better. Actually over Thanksgiving I am going on a long trip and will get a better idea as I am planning to evaluate them more thoroughly on this trip -- will post my findings.
 
It really comes down to three things, heat range, materials and exposure to the flame front.

Heat range unless your running nitrous or some form of Forced Induction stick with OEM specs.

Platinum and Iridium plugs are for long life not performance. Copper is a good all around conductor but it doesn't last very long. Silver is even a better conductor.

Many old school guys like to index the plugs to the opening faces the flame front. This takes time and measurements to get right. New plugs like the LGS are open and don't block in anyway.

The E3 design isn't what I'd call open to the front. In fact it's pretty isolating which is why it doesn't work well on V8 cars.

In the end a spark is a spark so anything will work and unless you has a problem to begin with changing plugs won't create any new magic in the combustion chamber. Making sure all the fuel is burned is all your after.
