Toyota MPG Chart in a non-modified 2014 Camry SE
 

Just out of curiosity, what's the best mpg an unmodified non-hybrid Camry can get of this generation? I think the absolute best I can get is 60-80+ Mpg on highways for a minute or 2, since the chart doesn't read above 60 mpg. The worst I can get is in city traffic with lots of stop & go traffic, poor traffic light sequences & heavy congestion yields sub 5 MPG. Avg overall is mid 20s mpg.

Not sure what I can do to net gains. I inflate my tires 1-2 psi above the door jam 35 PSI recommendation. Sidewall max PSI is 51. I hope to not induce premature tire wear by exceeding the manufacturers PSI rating. .

How accurate is the Toyota MPG screen?

I'm not aware of anyone else on this site with a Camry from those years. Manual or automatic? You might find what you're looking for in this thread:

Most vehicle fuel economy gauges tend to be quite optimistic. I drive a Ford Transit Connect for work and find the gauge can be as much as 20% high. In other American vehicles I've driven, the fuel economy computer stops counting when you're in neutral or at a stop. My Insight's computer on the other hand tends to be within 1% accuracy, possibly more accurate than fuel pumps.

I found that my tires wear most evenly at 44-48PSI. At the factory recommendation of 38, the edges tend to wear first. A few people on Insight Central run over 60 PSI, with one that I'm aware of running 120 in his tires with no reported issues so far. Not that I'm recommending it.

I wish I could speak more specifically for your car.

While OE gauges are not usually accurate, many have several modes, some may be more accurate than others. These mode may include tank average , instantaneous and on some cars the average for the last 15 minutes. Check your manual for specific information on you vehicle. If it didn't come with one the Toyota web site offers a downloadable PDF version.

It's automatic transmission. No other same Gen Camry drivers on this forum?

My mpg screen shows avg mpg per minute for the last 15 minutes. It fluctuates in the current minute's mpg bar, based on how hard the throttle is depressed.

Really could use a suggestion of how high on psi for tire pressure I should run for max fuel efficiency without wearing out the tires.

If you do a search in the garage it looks like only 2 Camry drivers are updating fuel logs.

My starting point for tire pressure is 4 PSI above recommended (cold), this is based on a general experience that I wear the inner and outer edges. Many here run much higher. Do a search here, many discussions of tire pressure and wear.

The factory gauge in my Nissan Versa is usually between 5 and 10% optimistic.

I tried to keep track for a 2018 Honda CRV. Average is 1.7 mpg higher than calculated for the first 20k miles.

You know you can just go to the Garage page and specify it list only Camries, right? Takes about ten seconds. Even if there aren't many currently being updated there are quite a few to look at, including a few with some depth of coverage.

The highest scoring Camry in the Garage is a '99 four-cylinder at 39.84 MPG average over 60k miles. I can see your car scoring short term moving averages touching 60mpg, but not over a whole tank.

You say you're facing a lot of stop and go, your biggest improvement will come from weight reduction.

I'll try checking out the Camry garage, thanks for the suggestion. Yesterday I inflated my tires to 40 psi, from 35 psi.

The car is usually empty, I don't carry a whole lot in the car. But you're totally right a weight reduction would show a significant improvement in mpg.

You are exactly right about touching 60 miles per gallon for a minute or two! On the highway I can seldom get over 40 miles per gallon for 15 minutes in a row. .

I think I read a tip about not running your heat until the car is at operating temperature , Because it's more efficient.

Although some say it's not necessary to warm up your car when you're first getting started. What are your thoughts on that? From an efficiency standpoint, is it better to warm up your car for a minute or two? Or until it drops under a certain RPM's?

If it's reading 60-80mpg it is either wrong or more likely you are going slightly downhill or losing speed. I might buy 40-50 mpg at 55 mph but not 60-80.

I think general consensus is to warm the car up by driving it. It's going to warm up over time regardless, and if you're driving it's doing useful work while getting warm.

You might look into a block or oil pan heater to warm it up on cheap grid power.

This was my personal best a month ago at 35 psi. I think the cooler weather has dropped my mpg. I tried going from 35 to 40 psi 2 days ago, but haven't seen significant gains. I'm wondering if I should move up to 45 psi, or go all in at 50 psi.

Go ahead and try 50! You're not likely to hurt anything, and if road noise or ride comfort are too low, you can always drop pressure back down.

Cold weather affects my car tremendously too.

Do you intend to start a fuel log?

Alright, I'll go fill up to 50 psi right now! :)

Honestly, I'm not organized enough to start a fuel log, I'm too scatter brained, lol. But I did take this picture of the avg mpg, & will happily keep you updated if it improves with boosted psi. Currently it's 27 mpg, & has on occasion dropped to 22 mpg when I do a lot of city driving.

I'm curious as to why the avg consumer doesn't care about mpg, when choosing a vehicle or even improving fuel efficiency in their current vehicles.

I would engine swap to the latest Camry hybrid engine, if a new engine was necessary, if it was cost effective & it were simple as plug and play, no custom mounting brackets. But I'm guessing since I have a 2014, it's not compatible with the bigger bodied 2018's & above.

Just went from 40 psi to 50 PSI today & still can't avg 40 MPG on the highway at 50-65 MPH at night. It was 43° F @ 9:30pm

Does temperature really decrease mpg that much? I was getting over 40 MPG on the highway just a month ago, at 35 PSI!! The temperature was 30-40° F higher & it was day time.

I won't block the grill holes, b/c closely monitoring the engine for overheating isn't something I want to worry about.

I'll either have to deal with it, or find some other simple things to boost mpg.

That brief 1 minute 60 mpg spike, was me coasting off the highway exit to local roads. The data certainly is interesting.

Briefly around noon, it was only a high of 53° F, but I was able to avg 40 mpg on the highway @ 50 psi, thanks to the car heating effect of the sun at high noon. I even had 3 consecutive minute peaks at 60 mpg & a few other good minutes with fuel economy above 54 mpg around noon.

Before I changed my engine, I could get 100+ mpg average (over 100+ miles) cruising at 50mph on a warm day, and had a best tank in the high 80's. During the dead of winter I struggled to get low to mid 50's, but it can to zero or below here. So yes, temperature can have a huge impact, as can stop and go travel.

I run a 75% grille block through summer. Once it's below freezing outside I block it 100%. When I first blocked it I kept an eye on things until I was confident it wasn't going to overheat.

In most vehicles, when you let off the pedal, the vehicle goes into what is called "DFCO" or deceleration fuel cut-off, where it burns zero fuel and your fuel economy is infinite miles per gallon - for example, 1 mile of coasting with zero gallons used is 1 mile divided by 0 gallons. Chances are good the Toyota display doesn't show this and just gives what is a large number for the car.

I had a rental Corolla a while back, I believe it was a 2015 with a CVT, and according to the computer I was able to get mid-50's MPG cruising at ~55mph once the car was warmed up, even with it being in the 40's outside.

What a difference temperature makes! 52°F, 50 PSI, AVG 50 MPG for 15 minutes on the highway!! Hybrid efficiency in a non-hybrid vehicle makes me smile, I love it!!

This may be my best new 15 minute avg ever, woot woot!!

Sadly, when I got to the city driving, back to paltry sub 20 MPG.

Thanks ecky, for advising me to go up to 50 PSI, was really nervous about trying that.

Does cheap fuel rob MPG?

Maybe my imagination, but I think the cheap fuel I bought yesterday from Fuel 4 gas station in Jersey City robbed me of power & MPG, compared to filling up at Shell. Same $2.39/gallon, but down to 6 miles left, & the Shell I pay the same price was far away.

Is it true running your tank all the way to empty can bring up sediment deposits into your engine & damage it? What's the lowest you feel comfortable running your gas tank to?

I don't like to run mine to "E" and never do. I usually refill no later than about the 1/8 mark.

It's not to avoid sediment in the tank, because the fuel pickup is generally at the bottom anyway.

It's just based on the principle that I avoid taking chances with running out of fuel, especially when there's no benefit to taking the chance anyway.

I generally don't run to completely E either, some people believe it's hard on the fuel pumps as the motor is no longer submerged in fuel acting as coolant for it. I don't concern myself with that, I just know where gas is cheaper and watch my range so I can make it back there.

Ethanol content can affect your MPG some, E10 has about 4% less BTU's per gallon, some cars follow the energy to mpg curve and will lose 4%. Others don't.

http://www.speedperf6rmanc3.com/cont...evel_Study.pdf

In that study one of the cars they used a 07 Camry 2.4 and ran different ethanol blends and recorded MPG and more. It actually got the best fuel economy running E30.

Ethanol content and quality will affect MPG

The expensive premium grades that some companies like to advertise - like Shell's V-power - have been tested here in Belgium, and while they actually do offer a slight MPG advantage, this simply doesn't offset the equally premium price for it.

(Premium petrol works better to reduce MPG, than premium diesel BTW)


If you can get the big brand stuff for the same price, go for it


In Europe, there's also little benefit when running 98 RON instead of 95 RON


That's what your fuel filter is there for

And there should be much goo at the bottom of the tank anyways .

I usually fill up whey the light comes on
Sometimes a bit earlier, sometimes a bit later

I don't mind running it down to an estimated 10-20 miles remaining range either

Unless you let it idle for ages, which an ecomodder wouldn't do, you can't run the fuel pump in a very low fuel condition for very long, or you'd run out of fuel :D

Temps make a big difference. From about 55F and up, my Prius makes summertime MPGs, from 55F and down, winter MPGs - and "winter MPGs" get worse and worse, the colder it gets.

Again, if you go to the garage page and look at some of the vehicles that have been updated for several years, you'll see a pretty clear relationship between fuel economy and the time of year. Warmer is gooder.

As to fuel grade affecting fuel economy, I haven't observed that. Then again I only fill up at about three different places, and always get the cheap stuff so I don't have a lot of scope for comparison.

As to the truck, I think it would run on straight Pabst Blue Ribbon so whatever pisswater fuel I can pour into the tank, it'll deliver some kind of performance.

Shell sucks(happened at several stations in town 3 of 3 stations 3 of 3 arco stations as well what a good scam) i only get 87 US out of the premium 91 octane pump as noted by the timing advancement table drop to 87 level. which is near 0 sometimes negative .

I do go to Chevron or mobil only No where else (unless it's a rental then it does not matter i get the cheapest **** i can find)

with 91 us octane I can see as high as 42 degrees advancement


it's VVT btw

it's normally on summer gas for the 91 oct so it's normally worth it(it's worth 1-2mpg more )


3.399 = 0.183cents per mile(18.5MPG)
3.859= 0.154-0.139 cents per mile (25-27.6MPG)


So regular fuel will cost $4.58-5.05 per gallon (25-27.6MPG equivalent. )


the inverse is at 2.89 a gallon at shown prices above

I only run the heat if I have a passenger, my car is overheating, or my windows are fogging up.

I used to have other problems in Phoenix.

Honestly it's very dangerous to run a 51 max psi tire at 33psi
it's under inflated

you can have a blow out :eek:


as you can see on this tire it's at 32psi Riding the side wall it wore the corners of the tire.

about 40% side wall compression Hot PSI was 36
I put it to 45PSI HOT PSI is 45 0% fuel lost to heat
