I just bought a 2010 salvage Prius. I have another 2010 I have been driving for 3 years so I am pretty used to the mileage I can expect under different conditions.
When the car is totally warm and I measure the mileage for 15 miles or so I get normal readings of mpg. But with a lot of 2-3 mile trips during the week I am getting about 10mpg less than usual compared to my other 2010.
Have had my 2011 Prius all of 4 weeks. Followed PC for months before the purchase, practice pulse/glide regularly and have really change driving habits to increase MPG. First tank was 51 MPG, than 48, 46 and now 45. each one was 75% city driving, 25% freeway.

View 7 RepliesGrill blocked today for the first time and have a couple questions.
Temps have been dropping more these last 3-4 days and have noticed my MPG dropping as well so I thought I'd try grill blocking.
Tempts have been and will be high 30s-low 40s in the morning and upper 50s to mid 60s for the high.
At first I just wedged the pipe insulation and drove one trip. I didn't feel comfortable that it would hold for the long haul so I added zip ties.
I used two pieces of pipe insulation 1/2 inch copper / 3/8 inch iron. Up close it looks like 2/3 or 3/4 of the grill is covered.
My two questions:
For fWT, at what temperature should it not exceed?
At what outside temperature should I remove the pipe insulation? In the Phoenix area, temperatures rise in March and sometimes we will have a short period of warmer than normal temps in February. I just want to make sure I do not cause overheating.

View 5 RepliesI have noticed over the past few months that my gas mileage is dropping (from about 29 to 24) on the highway and I seem to have lost some power. I know the car is getting older, but where do you think I can get some of it back? The plugs are only 20K old and the air filter is new.
It is a 2004 1.8t with 109k on it.
I have a 2004 Chevrolet Tahoe 2WD with the 5.3L V8. Tahoe has 134K. At about 125K miles, I replaced air filter with a K&N, new OEM spark plugs and spark plug wires. The Tahoe has been running great and was getting normal mpg until recently. 15mpg in town and 17mpg on the road is what I normally get. The last 3 fill ups my mpg has been below 13.5mpg. Car still runs great but at 13mpg it's starting to hurt a little financially. Weather here in NC has been normal, my driving conditions or habits have not changed, etc. What could be causing my mpg to drop by so much while the suv still rides smooth and straight?
View 4 RepliesGas mileage as stated by Suburu for the 2015 Outback (2.5 engine) is 25-33 with a combined of 28. Mine has never attained that and it has been steadily dropping. Now it is displays as 19 mpg. It is new and has just under 500 miles on it, and I read that the break-in is 1000 miles. That being said, shouldn't I be seeing better MPG than that?
BTW - I am hoping that I am just not being fair (to the car and to Suburu) and that I'll be up in the advertised MPG's soon after I hit 1000 miles.
With the colder weather in the NE, I am experiencing lower mpg with the ES 300h. We have had several cold days here, and my mpg seems to be going down. My driving habits have not changed.
View 5 RepliesI am the owner of a new 2014 Prius Two as of three months ago. I have really been enjoying the car, and it is certainly more friendly at the pump than my old Chevy Tahoe. I have a question as to why my mpg has been getting worse of late.
View 19 RepliesSo I bought a used 2010 Gen 3 with ~26,000 miles on it in July 2013. I started out getting 48-52mpg depending on where I was driving. I live in Raleigh, NC and I did notice a drop in drop in MPG over the winter ranging between 44-48mpg but the mpg never rose again as the months warmed and I averaged 44-46mpg for most of the summer. After changing my tires a few weeks ago I've dropped to about 40mpg regardless of where or how I drive. I bought Pirelli P4 Four Seasons 195 65R15 91T and have them inflated to the levels recommended by Toyota. 35/32 or something like that. Is it the tires or is there some other possible issue?
View 19 RepliesI am in the market for a used Gen III regular Prius. I know that battery in Gen III is smaller in size and weight, so energy density is greater. That's great. But I wonder if you've seen high mileage (>200K) Gen III owners experience battery performance deterioration, like someone experienced in Gen II.
My 2004 with 220K miles only get 44mpg in this summer temp. (I drive it a little bit aggressive, use AC, and don't care much about hypermilling) I think at least partly it is due to weaker HV Battery. I can clearly feel that now it is easier for engine to rev very hard when accelerate at 50 mph. That's not the case before.
When I bought the car in 2009, if I had 4 bars on my traction battery at night, it would have them in the morning. Now I can leave the car for 2 hours in moderate weather. When I drive off, it will show 4 bars but driving in eco mode w/o ac, it will drop to 2 within a mile and stay there for several miles before it starts to charge again. My overall fuel economy has dropped 10%.
View 19 RepliesWell been playing with all the mode to see what they do and the one thing I have noticed is I get worst mileage under ECO Mode. Why it doing this.
View 19 RepliesSo, I was in Wash. State for a while this month and rented a Prius. I decided to check some mileage on mountain roads, and here's what I got. All of these are indicated by the computer, so they are probably 5% or so high. Unfortunately, I did not see either the maximum incline or average incline of these roads posted anywhere, so unless someone else knows them, these numbers are not worth too much scientifically:
UPHILL:
Going uphill on I-90 to Snoqualmie Pass from the West (from Seattle), at 70 mph (the speed limit), fairly steady, with a few decreases for traffic and curves: 18.6 mpg.
Going uphill on US 97 to Blewitt Pass from the north at 50 mph, also the speed limit: 27 mpg.
Going uphill on the Olympic National Park road to Hurricane Ridge, speed limit varying between 35 and 25, with a couple of sections as low as 15 mph: 22.1 mpg. (Maximum incline here might have been 6 or 7 percent).
On the Hurricane Ridge road, I reset the Trip Meter A about a mile from the top (interestingly both segments of the uphill trip registered 22.1).
DOWNHILL, mostly:
The Hurricane Ridge downhill produced an interesting number, because I didn't reset the thing at the top, so I had a mile of 22.1 mpg at the beginning. You go down for about 18 miles, losing about 5200 feet of altitude to nearly sea level (Strait of Juan de Fuca). We kept driving, and at 24.7 miles (so about 6 miles of driving near sea level), the mileage gauge still showed 99.9 mpg. (I took a picture, but it's too fuzzy to put in here.) It was a couple of more miles before I noticed that the trip mpg was down to about 91.
I went to the local dealer at about 6K miles to get the free 5K service. The invoice said synthetic service, so it should be the 0W-20. Now the average mileage since the last fill-up is lower by at least 3-4 MPG. My driving habits haven't changed. I inflated the tires to above 40 PSI. I looked at the oil. It is medium amber colored. (I forgot to look at it before the oil change. )
View 19 RepliesTemps average maybe around 10-15F in the winter so mileage won't be great. Tires are up, grill is blocked. We're getting about 42-43 on the HSI which means about 40 mpg in reality (I've checked this many times and Toyota is off by 3 mpg on average in our car). But Mike in Maine shows up with a 60+ mpg in 15F temps, and I know my fellow Alaskan, Spiderman, is getting 50+ easily. My commute is more highway than stop and go. I don't use P&G but I'm very gentle with the go pedal. I feel that I should be getting closer to 50 here, even with the temps. Is this too much to ask? Maybe it is...
View 12 RepliesMy prius is almost 5 years old and has 88K Klm (49K Miles) My battery has gone down to one bar of late. This never happened until recently, never went below two. The bars seem to fluctuate up and down much quicker than before. My mileage is slightly down but it could be because of other reasons. Does it seem that there is something wrong with the battery? No warning lights are coming on
View 14 RepliesI have 2600 miles on my 2012 mdl II. A month old. I have been averaging 47.5mpg since day one based on miles driven and gas put back in tank at each fill up. I have used only Mobil bottom 87 oct gas.Last fill up got me 48.2, very nice, then I filled up with mid grade 89 oct as it was all I could get then. The next day I was in the dealer for my 1000 mile checkup. when I got out my battery was down to 25%, okay no biggie. Then from there on out I notice my mpg changed alot. The comps used to read 49.1-50.1. Now it reads 42.2-44.1. I drive the same way and my 85 mile round trip to work hasn't changed. My first fill up since the dealer, got me 45.0 mpg. wow a big drop off.
View 4 RepliesI commuted to LA 2-3x a week. The mileage on my car is now at 90k. I have had an average of 40 mpg since new, but suddenly it began to drop. We took it to our local Toyota dealer and was told it was most likely a cable that needed to be cleaned. That was $160. It didn't work.
View 10 RepliesThe humidity has an affect on my MPG. I noticed that my MPG went from 49 - 52 MPG down to 44 - 46 MPG when the heat & humidity started here in June. Yesterday a cold front came through and the humidity dropped. I filled my tank up and noticed my MPG is back up to 49 MPG, so the only thing that is different is the humidity. The cold & humidity does affect the MPG (approx 4 - 6 MPG).
