I've been running full synthetic for 35K miles and once I passed 50K miles I had a jump in mpg I really don't understand. My 5-speed gets 38 to 40 mpg and I'm no saint for letting it out in 2nd and 3rd.
Before 50K I was getting 34.5 to 37. |

You give all all of us great hope! I have had a few +40 MPG tanks, but mainly in the 37 to 39MPG. I have under 25K but now I am looking forward to see what happens when I turn the golden mark.

The arguments havent changed in the last 2+ years!!!
Synthetic oil/highest tire pressure you're comfortable with/conservative driving ... will keep most people happy with their mpg's. I averaged 38.4 mpg the first 50k. Peronally I keep with the flow of traffic especially in long stretches of no passing zones...idiots behind get frustrated.

Dependent upon many variables: driving style, conditions, hills vs. no hills, was there a change in driving habits from pre-break in to post-break in period?
I too have not seen an increase in efficiency. Conditions are pretty much the same (varied only slightly, depending if I take this road for a mile or that road for a mile to get to my house). Driving habits, actually have improved, but this is offset by the fact that I have a very hilly ride to and from work M-F (no better route to take, unfortunately, it's either the hills, or deal with construction that has what used to be a 4-lane road down to 2 lanes, and moves at a snails pace).

My experience has been that there was no gain in MPG as the car was breaking-in. The graph below represents every single tank of gas that has been run through my car since the dealer filled it on day one, which was April 13, 2009. The last data point was when the odometer was reading 12,701 miles.
The high points on the graph were for fill-ups during long trips. Gassavers must include only the most recent several tanks when it calculates overall MPG average, because my spreadsheet at home tells me that my overall average is 38.21 MPG, not the 38.69 MPG shown below. |

rofl, the so called engine break in period is done at the factories nowadays.

---New vehicles will not obtain their optimal fuel economy until the engine has broken in. This may take 3-5 thousand miles.--- Now, the above statement is written after over 100 years of mechanical engineering science and also data from all vehicle and engine manufacturers up to 2009. And it is found on http://www.fueleconomy.gov/FEG/factors.shtml. I also am a very successful motorcycle racer, and have built and torn down many an engine. I am also a mechanical engineer, and have been one for over 30 years. I build machine tools for a major defense contractor and turbine engine manufacturer. I do know precision metallurgy and how lubricants work. I do know just a teeny bit about engine and materials science and was not born yesterday. I also build and operate my own 7 1/2 g live steam locomotives as a hobby, [besides racing motorcycles]. So tell me something stupid about engine break in, and I will call you out. Proof ? will take a week of engineering classes...but I can't fix stupid, so maybe that won't do any good either. FACT- one she loosens up from 'out of the box' it will get optimal mileage, and that will take several dozen severe cycles to do the loosening. Your mileage will vary. Don't forget brake drag. new pads and rotors may have a small bit of drag that also loosens up over time. my whole point is, I am surprised for a 35 mpg vehicle how easy it is to get 41-43. the percentage gain is huge. only a tiny smidge of this is break-in looseness. I was 41 max, now I get 43. I surely believe those 2 mpg are the break-in mpg. I make the exact same 400 mile trip with the exact same gross vehicle weight every weekend... so I have a good test bed. Ohhh... now lets get into an internet fight about the whole thing. I am way too tired to attempt a fruitless bitchslap over tcp/ip. internet arguments never work. so keep believing what you believe.

Wow, so impressed.
Here's my ACTUAL DATA (keywords) to back up what I am saying. Where's my big amazing jump in fuel economy at 3-5K miles? Things to note: 1. When I initially drove the car, I knew nothing about hypermiling. 2. I started to read about hypermiling on this forum and have tried a lot of different things to increase my MPG. 3. My commute is usually just going to work -- but I do take trips on the highway every couple of months or so. 4. I bought an ecometer recently which has helped me find tune my MPG even more. 5. There is no appreciable increase or decrease in MPG -- except as reflected by winter months and increased use of defroster and remote starter. So again ... prove it! Where's your records of fuel usage?

Average mileage and speed, too
What am I doing wrong in consistently getting 36 mpg? Maybe regularly traveling at 75 mph per speed limit as generally indicated on primary so. Az roadways?
Congrats for all getting beyond expected mpg for yaris, of course. For comparison purposes it would be useful to include guesstimate of av. speed thru time, in addition to mpg. --thanks. |
