MPG's

[MazdaTwo]

....Well now, I use the same gas station but whatever pump is open and its fill to the click each time......I will be doing a more controlled test asap....Im also not adverse getting a few of us together and run the same route and see the results...

Yeah, I mean, I'm not bashing you. It's just one of those things where it seems pretty impossible to get 55mpg out of a car that only advertises "up to 35mpg." I can just see that for whatever reason, your test is introducing a variable that is putting you far above any numbers anyone else is seeing. You are running the 1.5L, right? Not the 1.3L?

Also, no one every answered my question. Are you guys running 5W-20 instead of 0W-20?

 

[Axela05]

I'm running 0W-20, Automatic, Always use Shell 87 octane and average around 29mpg City/31Hwy. I always keep my TC on as well.

Yes, I have the 1.5 with a 5 speed.....Perhaps my technique is superior...I also run a can of Gumout to keep the injectors clear......

Mobil 1 Advanced Fuel Economy 0W20 for me, with OEM Mazda filters. 87 octane Costco gas usually, I don't mess with the TC, and keep the tires around 38psi. Last tank was 38MPG, hopefully it'll be a little better at my next fillup tomorrow.

I think I'm going to try keeping the TC off all next week to see if it makes a difference. We're expecting similar weather to what we've had this week, so the conditions under which I'll drive should be close.

Same here, I'm running Mobil 0w20 with OEM filters. When I went to buy 2 filters at the dealer, they said they would sell me 4 for $20 so not a bad deal.

I have a 2010 SUV in the garage that had a clogged oil port at 15k miles due to oil filter material (skinless filter). This would have been a $5k repair. Thus why I always use the OEM oil weight and one to their certification. I usually do NOT use OEM filters but GM would have had to prove the material was from my Wix filter. I've done my own oil changes for around 30 years and this is the first time I've had an issue. But just be careful about running any non-recommended oil weights, there is a risk of being denied warranty claims.

I told him, explained it was not a "top tier" gas and didn't have cleaners/detergents in any grade. Gave me a web site "www.toptiergas.com to find out what companies do have the detergents added. He said these engines are prone to carbonizing the valves without the detergents, and he said he had seen stuck/bent valves from this buildup.

I run a mix depending on the price but an interesting statement. I work in an area related to fuel so gas is gas when it's shipped since refineries rent space for a major pipeline. For me, it's the Explorer pipeline that feeds north Texas. But the additives are added once the fuel is picked up at the terminal. I'm on the fence about the magical additives. The main reason, we now have 10% ethanol in our fuel year round and believe me, ethanol acts as a detergent. So I'm wondering what other additive is actually doing anything else to really clean the system.

I've been to the top tier website but personally it's a marketing site for those brands. I'd rather see some objective third party evaluation. The dealership may be giving good advice but most of those guys are just parts-replacers and repeat what they are told without any actual facts.

I'm not arguing but I'm just skeptical.

I'm running 0-20 from Mobile One too. Have gone on a couple of 50 mile drive this week and I've noticed that keeping my speed around 65 I pickup an additional couple of mpg(36.9) that I lose just by increasing the speed 5 mph. Wish I could get the same mpg @ 70 or 75 MPH. Going on another 1600 mile trip at the end of the month and it could save an hour or so driving time each way. I'm wondering if going to 38 or 40 lbs of air in the tires could give me the extra mileage. I'm at 35 lbs now.

 

[stevenvillatoro]

I picked up several MPGs by running my current Honda Civic Hybrid tires at 44/42 PSI (front/rear), and improved braking and handling performance in doing so. Tire wear has been excellent and even, besides. Try raising your pressures to the maximum you might want to try, run a full tank to see how that pressure affects your fuel economy, and then back off your pressures gradually until you find the right MPG vs. comfort/ride level for you and your car.

Hi, I have some numbers I want to share, new M2 Sport Auto, Tank 1, from the dealer, 32 MPG, lots of City driving, lots of short trips and quite a bit of A/C. Tank 2, 87 Octane, pure gas with no ethanol blend, mostly Highway, little to no A/C and got 41.7 MPG. Tank 3, 87 Octane, 10% ethanol blend, 36.5 MPG, Highway/City blend maybe 70/30, no A/C. Again, this is an Auto so I am very happy with these initial numbers and they are much better then I anticipated.

Just took delivery on my Mazda2 Touring w/5 spd last night and took it on a 130 mile pleasure drive through the hills and winding roads around Cincinnati. When I got home, it registered 40.1MPG on the trip computer. I'm guessing the actual mileage was a bit lower, but I was impressed nonetheless. I'll start seriously tracking my fuel econ (pen and paper at the pump style) once I get through the first tank of gas and get my tires inflated to how I want them.

 

[Spindog]

After using Mix-I-Go twice in the first 2 tanks (double dosage , 2 oz. as per directed) and filling again without it , I waited until the second to last 'digital block' disappeared to begin the real test of MPG. On this block , 2/3rds tank full , I have driven 44 miles and it's still there. I never drove above 70mph on the highway and typical stop and go rush hour , and regular ,not in a hurry driving (no stomping off the line at the light , no hard braking) TC was on. No AC. I expect the block will disappear shortly after I leave for work tomorrow , but WOW. (boom06) Btw- this is an automatic.

 

[Red2]

Where does one find Mix I Go? Sounds worthwhile!!!

 

[Spindog]

I bought a 32 oz. bottle for $20 on Amazon.com One bottle treats 320 gallons.
It's made by Bell Performance.

 

[dqniel]

Elzoom's numbers are believable with the proper technique. I've seen hypermilers get 70mpg on the 5 spd Mazda2. Proper tire pressure, utilizing low RPM shifting, keeping low speeds, turning off the engine at stops or while coasting (dangerous IMO, but possible) and most importantly maximizing the change of potential energy into kinetic energy makes it possible, albeit difficult. I can get nearly 50 while shifting carefully and keeping the speeds low on relatively flat roads. It's just no fun to me once the novelty of super high efficiency wears off. I'd rather drive safely, but still with some fun involved, and get upper 30s to low 40s

 

[Spindog]

If you want to kill your starter really quick , turn your engine off at stops.

I've never heard of that problem. I'm not saying it doesn't exist, but could you point me to where hyper-milers are running into that issue on modern cars?

 

[Axela05]

Quick check in. My fiance and I drove from Jacksonville, FL to Tampa, down to Key West and then back to Jacksonville (approx 1,200 miles) for our vacation last week and low end, I was getting 34mpg. High end I got was 38mpg. I didn't go over 70mph almost the entire trip, unless I had to pass someone (then it was 75mph). We only spent about $125.00 in fuel also. Overall I'm VERY impressed with the numbers, since I have an automatic and all. Any who, just thought I'd share

 

[Red2]

My mileage keeps getting better and better First I slightly overinflated my tires (running 38 psi on all 4). Also started using Mix-I-Go. With the tires at that pressure I saw 38 mpg consistently w/ 50/50 mixed driving and as high as 41.3 on a tank that was almost all highway. After the first tank running Mix-I-Go I hit 44.7 mpg for the tank (376 miles w/ an 8.4 gallon fill up after about a 40/60 city/highway split). I drove normal on that tank (which for me includes the occasional hard run to redline as I merge into freeway traffic). Just started my second tank w/ Mix-I-Go and my miles vs. bars gone is looking even better than the top of the first tank.

 

[stevenvillatoro]

Congrats. How much does Mix-I-Go cost to use per tank or gallon of gas? In other words, is it an economical additive? Have you used it before with success? Would have been nice if you'd checked your tire PSIs separately from the additive, to observe the influence of each. 38 PSI is still low, per hypermilers. Have you tried higher pressures yet? Thanks for the report.

 

[Red2]

I ran the tire pressure up for several weeks before adding the Mix-I-Go and averaged 38, so the additive almost has to be the bigger factor in the improvement. You can order Mix-I-Go directly from Bell and it's very reasonable. The 32 oz bottle runs $23, or a gallon is $75. Each ounce treats 10 gallons of gas, so the 32 oz bottle would treat roughly 30 tanks of gas at about $0.72 per treatment. I'd call that economical!!!! It gets even cheaper if you buy the gallon.
