r/hypermiling

Hi all, I have a Yaris mk2 2007 (U.K 🇬🇧) MMT (multimode semi-auto) 1.4D (Diesel) which has done around 101000 miles.
I drive it locally daily for around 10 minutes to get to work which has a mix of 20-30mph roads, few turns and traffic lights.
I’m always getting around 29mpg for my fuel economy.
I bought it at around 98000 miles so don’t know how it was before.

I’ve tried Redex Fuel System Cleaner but didn’t make a huge difference.
Looking at some posts I think it for the small engine it should be getting around 40mpg.

I have also relearned the gearbox as the car lost its creep and the gears would rev a lot when it downshifted. Relearning fixed the gearbox but not the mpg.
My yearly service is coming close so could engine oil be affecting mpg

Anything I could to help increase the mpg.

Ciao a tutti!

Io con la mia, modello del 2022, sono sui 3,2 l/100 km e con un pieno riesco a percorrere circa 900-950 km. Faccio prevalentemente autostrada, con un’andatura intorno ai 90 km/h.

Voi che consumi riuscite a ottenere? Scrivete anche l’anno della Yaris e il tipo di percorso che fate (città, misto o autostrada), così possiamo confrontarci!😎

Im leasing a 2024 Air Touring, for 3 years, 15k/year.
I touched 35k recently and still have 14 months left on the lease.
Need advice on how should I proceed.
I love driving the car and I expect to reach 60k by end of lease term if I do not change the way I’m operating.

The residual value on the contract is $53k.
I plan to buy the car at the end of lease provide Lucid is open to negotiate the value.

If not, should I stop using the vehicle for to keep it under the limit?
What has been others experience on Lucid open to reduce the buyout price?
Or should I keep driving and pay excess miles charges if Lucid is firm on the buyout price?
My alternate is driving a regular SUV if not the ev.

I have tinted my windows and have upgraded to CCCv2 as well.

I’ve heard some people say to stay in the upper ECO zone, while others say it’s more efficient to briefly accelerate into the POWER zone and get up to speed quicker. I use eco zone and try to never touch power .
My instant MPG drops to around 8-15 mpg during acceleration, so it feels like it’s hurting my overall fuel economy and takes forever to get up to speed .
What are you all doing to get the best MPG? Upper ECO, POWER, or something else?

26 Camry hybrid and I have Scanguage as well .

In my head it makes sense to save fuel by shifting to neutral at stoplights when using an automatic transmission because the engine is under load trying to creep forwards, is this a valid technique?

I’m trying urban delivery hypermiling and stop and go makes it hard to improve

Hi!

Wondering if it’s okay to instead of get a hub cab cover for wheels to just tape up the gaps and have essentially the whole rim area from edge to edge covered in duct tape?

I have metal rims on 17 chevy volt btw

Also planning on taping up gaps for at 2k mile roadtrip.

i’ll be changing oil and adding fluids right before too!

Will this still improve efficiency?

So I purchased a 2008 model Prius that had been sitting, one owner, but it sat for a little while after he passed. I’ve been cleaning it up, put wheel bearings on it, changed a capacitor, gave it a tuneup, and still kind of working out some of the bugs, but I kind of expected the fuel economy to be a little bit better. It’s running on the original battery, which was tested to be at a little above 80% of the original capacity but otherwise considered to be functional. I’m already used to driving a hybrid, my daily driver is a CRV hybrid, but honestly, this thing only gets marginally better gas mileage than that at 42.6mpg. Is there something I should be doing, or is it possible that my ancient battery or old engine are just not ever going to be as efficient as they were?

So I have an '05 xB. Its a box on wheels. This weekend im making a front air dam and side skirts as well and a rear belly pan to help with air getting caught behind the rear bumper. Once I figure out how to mount them I have flat wheel covers, and once my temp gage shows up I will begin slowly blocking off the front grille. I may also raise the cowl side of the hood to allow more heat to escape while block off more, but ill try thay after I get the temp gage

A friend mentioned making a kammback. Im not opposed, but not sure if it would improve it enough to have a goofy structure on the back of the car.

Have you experienced the same thing?

it’s gotten boring, boring In the sense I can’t make any further progress because my approach is already so optimized (I’m getting 36 mpg and/or 6.4l/100km city)

I’ve been Hypermiling for a while and I already consume 30-35% less fuel than my peers

I don’t know, maybe I should start doing aero mods to make things interesting again

Have you ever wanted to do the same?

I feel it would be interesting to take an 8.1L V8 suburban 2500 from the 2000s and try and hypermile it, I could probably get a very impressive 16 mpg out of it

Hey im interested in buying a 99' Lexus RX300 that I will only ride on the highway and i'm wondering what can be done to improve the fuel economy. I have seen dinner plates on wheels and rear wheel covers and diffusers but by how much do these modifications improve fuel efficiency and how can one make (or buy) them? Thanks

Hello hypermilers! I am going to be attending trade school later this year, I will be going to a college in another city, about 100km away. After doing some quick math I've decided that driving is the cheapest option, even in my old pickup. I won't buy another vehicle, because after buying the car, putting winter tires on it, and making reliable enough to trust to drive 200 km everyday for three months, I'd spend more than it would be worth. So I'm driving my old pick-up. Now, I will be spending roughly $4000 on gas, so I'm hoping to increase my fuel economy. I will be employing driving techniques of course, but I'm wondering if any aero mods would be worth it. I was thinking about installing a tonneau cover, some side skirts over the rear wheels, an underbelly, and damming the front grill. I was wondering if any of you have done these mods, and how they affect fuel economy. I know it won't be much, but my truck gets 23L/100km on average, and every bit of improvment will help. Please give your opinion:)

Tell me what you think it’d look like

Gas stations would go bankrupt in our city

The mayor would hypermile to conferences/the legislature
