Prius C Fuel :: MPG Decreased After Tires Replaced
I have a 2012 prius c with 72k miles. When i bought the car, it took a while for the fuel economy to increase. i drive 100 miles a day at 85mph and topped out at 52mpg. pretty damn good, if you ask me. im all interstate with very little city driving.
2 years later, its time to get new tires and ever since i changed them, my fuel economy has decreased to 45mpg.

I been wondering if I put light weight 17-inch rims on my car with low profile tires will that destroy my mpg?
View 9 RepliesPrius (2010-12) Fuel :: MPG Dropping - Replace With New Tires?
So 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 RepliesPrius (Gen 2) Fuel :: 2007 - Mileage Drop By Over 20% When Put Summer Tires
This Easter I put summer tires on my "new" (owned about 4 weeks) prius -07, and cleaned and greased brakes.
With winter tires (almost new Nokia hakka xx, stud less) I got 4.5 l/100km (52mpg) easy and 4.2 (56mpg) at best, now I get 5.5 (42mpg) and 5.3 if I struggle, if I relax and put cruise control on I get 5.8 (40mpg). I travel 100km to work every day.
Summer tires is Michelin primacy (about 2 seasons?) pumped to 3.0/2.8 bar (over inflated).
Brakes don't seem hot after drive and they was really clean and easy to move after my service so my guess is that they work fine...
Mileage went down over the weekend so I see a clear link.
It was more fun trying to hypermile at 56mpg aiming for 60 then it is at 42 aiming for 45...
12v battery charged, just in case. Still same temperature out 1-8 C. Oil and all filters changed first week (will change trans axle oil in summer). Travel to work got 4% shorter so tire size must be a small reason to the +20% problem.
Prius (2010-12) Fuel :: New Tires Lead To Drop In Gas Mileage
Last October I needed new tires, so I had Michelin Defenders put on my 2011 Three in place of the OEM Firestones. The Michelins perform well and are nice and quiet, but...
My gas mileage (both indicated on the dash and calculated) has dropped by about ten percent. In researching the two brands of tire, I found that the OEM Firestones are rated at 836 revolutions per mile, and the Michelins are 839. I'm wondering if this is the reason for the apparent change in mileage.
Prius (2004-09) Fuel :: New Tires - Bad MPGs - Service Light Came On?
My wife and I were driving around town the other day. While merging onto the highway we hit a nail. I put the donut on and went to TiresPlus where I have gone since I started driving. I had been thinking about replacing the front tires due to wear and the nail wen in the side on the rear. Anyway I purchased 4 Firestone Affinity Touring tires and went on about my day. My wife drives 100 highway miles a day and then does some city driving. This week she has lost about 5mpg's according to the display average. Also the service light has come on. Can this all be tire related?

View 1 RepliesGTI 337/20th Anniversary :: 3 CEL Codes - Idle / Fuel Adaptation / Overboost Condition
I recently installed the apr turbo compressor inlet hose and eurojet smic on my 20th. I am running apr stg. 1 software on apr diverter valve. I also have 3" ghl turbo back exhaust. The three codes I am getting triggered shortly after the 2 upgrades I mentioned above we're installed. In detail the codes read specific:
-idle air control system: RPM higher than expected
-bank 1 mixture adaptation(add): system too lean
-turbo/super charger: overboost condition
When the car idles it seems to miss every now and then I think cause the fuel mixture. It also does idle higher than it did before (~900rpm) when the cel comes on it seems to fix the missing issue but not idle rpms. I am running the stock ko3s turbo and am soon planning on a Eurosport cold air intake. Am I harming my engine? Can I get the light to stay off?
Toyota - Prius - Driving - Tires - Winter :: 2008 - Car Literally Would Not Move Forward
I had terrible issues driving in the snow /ice last month. The car literally would not move forward. I bought 4 new Michelin Tires (Weatherwise II) but am thinking I should put on Snow Tires. Can I put them on the front only since the car is FWD? Also, which tire to choose?
View 11 RepliesPrius (Gen 3) Fuel :: Fuel Mileage Reduced When Driving In Rain
We gave the Prius a good workout in the rain for the first time today. Central Florida has been having serious amounts of heavy rain, creating water covered roads in our area. Normally the digital fuel mileage display shows around 55 MPG for most of our driving. However today it dropped to the upper forties very quickly.
We were running the wipers on continuous (low and med speeds), the AC (defrost) was running to keep the condensation off the windows, and the headlights were on. I wonder if the extra resistance of the water on the road also had an effect on the fuel mileage.
Even though we hit some fairly deep water and created large amounts of splash, the car tracked straight, the brakes worked well, and the power was totally uninterrupted. Other than the poor fuel milage we were impressed.
Ford Excursion :: 2004 Expedition Overhead Console Identical To XLT?
Do the Ford Expedition overhead console is identical to the Excursion? I have an '04 XLT and the overhead console is damaged. I found a replacement unit for the '04 Expedition in the same color and the seller has no idea if the units are interchangeable.

2010 Prius, ~250k miles, pressing power button to turn off on results in a semi-regular "pulling the plug experience" instead of a graceful shutdown displaying the mileage and time, can happen a couple times in a day.
IGCT relay and both integrated relays replaced in the fusebox, as well as power switch. Takes between 2-90 seconds to recover and turn back on. Lights out and dark during that period. No codes shown in Techstream.
Sometimes is bad enough that the Nav system reloads the DVD and settings. However, bluetooth and all other functions work once it's up and running. HV battery replaced last year, as well as 12V battery.
Rough - Engines - Storm :: 2008 BMW X3 Hesitant On Acceleration After Driving In Dusty Weather Condition
I was caught up in the middle of the haboob (major dust storm) in Phoenix this summer. I drove through it in my 2008 BMW X3 (40K miles) for about 45 minutes. Ever since, the engine has been idling rough and hesitant on acceleration. I had replaced the air filter which was full of fine dust particles and thoroughly cleaned and vacuumed the internal of the filter housing. I also used Chevron Techron fuel system cleaner on a couple of tanks. The condition has improved a bit but it is still not back to how it was before.
View 2 RepliesPrius (2004-09) :: Air Condition Not Working At 86F
I bought this 2004 Prius in 2010 with 104K miles. Now at 117K. When outside temp goes to 86 F or above, the a/c blows warm air. If I stop A/C for a while, and restart it, it will blow some "cold" air for 10 seconds, then back to "warm" again. at below 82F it seems work normally, although I never felt "cold" enough like my other car Lexus LS 400 1998.
My mechanics found (using his diagnostic device) that the thermometer temp measure indicate as 28F when outside was at 90F. He can not figure it out. Is it possible that temp sensor (thermometer) gone bad? Or it is just a loose connection which might cause the resistance value change? He added enough refrigerate fluid for the car.
I noticed in glove box there are evidence of glue used. I suspect that the car had some body damage on right side and being fixed.
Anyway, the a/c problem so far happens consistently at around this temp. I have no any other problem on this beautiful car.
Prius (2004-09) :: Air Condition Blows Hot Air Sometimes
My Prius air condition blows hot air sometimes, sometimes it works fine, warm weather seems to increase the problem. Took it to the dealer, they couldn't duplicate problem, said it was fine, but it is obviously not. Where should I start, don't like the replace parts till we figure it out thing. Don't think its the compressor b/c sometimes it works, sometimes it doesn't. Fan is working fine.

I have a 2002 prius with 130,000 miles on her, and so far so good except for a small problem for the last three months, I get an intermittent P0171 code. I know it means Lean Condition in Bank 1. However, I can run the car for weeks without it coming on. If I go full throttle getting onto the highway for example it may come on, but even then its not all the time. Not sure why only full throttle. But if I drive her gently, I will never see the CEL at all.
Fuel economy is around the usual for me at 46-49 mpg with average speeds of 75-85 mph. I don't think its vacuum related.

This can be heard at low speed. two to three bars on the blower speed indicator. It sound like running water. It is not the air conditioner when the compressor in on.
I can not listen to the radio all the time..... when it is peace time, radio is turned off. It sounds like the bearing is going. Had it looked at and was told that it is normal. The DC motor is suppose to be quiet?
Prius (Gen 3) :: Never Get To Ready Condition After Pressing Power Button
2011 Prius with 30,000
At the first start of day when I pressed on brake pedal and got the green light on power button as usual I pressed power button and never got ready condition, trying to figure out what is happening I have had this condition occur almost every morning (outside air temp around 40 degrees F) also when I went to train station to pick up my daughter I shut off for about ten minutes and it happened again.
