WORST full tank gas mileage you ever got?

That's OK. I don't really care to post those horrible low numbers.

 

I have never had a serious problem in snow with either my '04 or my '10 Prii. I do use Blizzak snows on all 4 wheels and that helps a bunch. Steady speed, not too fast and avoid the brakes and the car does fine.

 

Well you had to get all technical on me... . I was drove using CC at +3 over the posted limit. (Phone GPS indicates that the car spedo is 1mph low.)

 

49.8 mph calculated by hand.

I filled up in Denver, drove to Casper, Wyoming did a bit of running around town, then back to Cheyenne, Wyoming where I filled up. Distance driven was 484 miles. I was doing pretty good in Colorado, speed limit is 75 but traffic kept me slower than that. In Wyoming the speed limit is 80 and I was able to maintain that almost the entire time, maybe got scraped off on a trucker a time or two but no serious slow downs. Had a pretty terrible cross wind as well. When I get asked by friends about my gas milage I always tell them the worst I got was 49.8 and it "pissed me off." Truly I'm quite pleased with it, all things considered.

 

Your Gen IV Prii are really making me jealous of those numbers.

My worst tank with this Gen II was 34.80 calculated, 35.2 on the screen. For over two weeks the car was used in super short (<3 miles) hops multiple times a day. Less than a mile to work, park it for 2 hours, less than a mile home, run our daughter 2.5 miles to school. Afternoon was less than a mile to work, park for an hour, go pick up our daughter from school, then back home. Throw in short hops to the market and doctor appointments and for over two weeks the car never got on the freeway. It was very rarely over 40 mph. The final part of that tank was climbing Cajon Pass (5,000+ ft.) with the air conditioning on and then filling it up on the high desert. That tank was about as bad as it can get.

I got better mileage running the mountains of Utah at 80 mph in 100* heat with the air on.

 

The Gen II wasn't actually designed for that. It's great as a stop and go commuter but not when you have to keep turning it on and off. The ICE kicks on every time the car is turned on. Add to that the fact that the car never has a chance to properly warm up and you can kiss good mileage (for a Prius) goodbye. It's at its very best when it can be driven steadily between about 40 and 55 with at least 5 or 6 miles to start..

 

34 mpg, Texas Blue Northern.. 30+ mph head wind... boy was that 2004 Prius whipped all over the road...

 

Filled up this week - hand calc was 52.7, display said 54.8 or something similar. This was after the road trip with approx. 140 mi of terrible freeway mileage, otherwise it would have been higher for sure.

Switching to PWR mode per Coast Cruiser and will report back on next tank. It will be higher, I'm sure.

 

Don't go changing your story now....(I'm kidding!!)

Switched to PWR mode. So far my report is:
1. Wow, it's sensitive!!
2. Got 70.3mpg on my 15 mi commute home. Pretty dang good!

And, I only meant that I'm sure the next tank will be better because I won't have that bad road trip bringing down the average. Plus, I feel like there is a learning curve, and we are only getting better at driving this thing. Logged about 1,400 mi so far.

 

Heavy rain at 60-65MPH will push you close to the low 50's or high 40's. I always slow down anyway so I have never seen anything below the mid 50s for a 100-400 mile check. 57 MPG driving 65 with cruise on and a full load/my last trip. Cruise can kill MPG but I have to use it since the seats aren't perfect.

Gen 3 was probably 44 MPG with rain at 65MPH.

 

Coast Cruiser, does that fat woman need to be alive

 

Still a Shakey's out there????????????????????????
