With Gas Prices Hitting Record Highs, Here's How To Get The Most MPGs Out Of Your Subaru Vehicle!

[@pricklydingus8604]

My STI is extremely fuel efficient. It efficiently consumes premium gas like nobodies buisness.

[@dougrodriguez4977]

I have a 2L STi with a vf48 and injector dynamics 850cc fuel injectors, it makes fuel disappear very quickly. I just removed the 850cc injectors and went to dark blue STi 565cc injectors. I’m also installing a vf35 and lower the boost to 18psi hoping to cut down on fuel consumption.

[@cnobillbradley9673]

And so it goes with my forester XT too. I just can’t help it😊

@@dougrodriguez4977 im looking into some 1100cc side feeds, how bad was your mileage? Im on an fp blue with a 255lph fuel pump and averaging 13.5-14mpg on a 2006 with 156k miles

[@dougrodriguez4977]

Keep in mind my STi engine is 2L, not 2.5L like yours. I never calculated MPG’s, didn’t really matter when fuel much cheaper. Now fuel prices are much higher, it got my attention. I could not justify owning a 2.5L STi with a big turbo and fuel injectors. Best of luck to you.

The name of the game is "conservation of momentum". See a red light in the distance? Take your foot off the gas. SLOW to a stop, try not to COME to a stop. Also, your MPG/pocket cash is worth more than the person's attitude behind you. 👍

[@iriezorroloco]

Blows my mind how 80% of drivers have zero concept of this. Accelerate to the stop light burn up your brakes, then accelerate out of the stoplight.

[@OutsideTheTargetDemographic]

@@iriezorroloco Great way to burn through brakes and gas. 👍

[@timsilva1944]

Yeah. I used to ride a couple miles through several stoplights to get to a creek parkway path. So I would soft pedal to the next light and anticipate the green, where I would ride past all of the vehicles that went by me. Some of the drivers were clearly upset as they would gas it to catch up and pass, just to stop at the next red, where I would repeat the procedure for a few blocks. Some people never learn.

[@mkloudsql3285]

Yepers... I love my manual for this reason, just take it outta gear roll at red lights and down hills. Dont ride the damn clutch from stop to go

[@timsilva1944]

@@mkloudsql3285 Manuals rule! Increasingly hard to find and can be odd coexisting with other drivers. Take stop and go traffic as an example. I prefer to leave a space cushion in front so I can just leave it in 1 gear and crawl, versus constantly clutching and braking. You have to be on your game as some knucklehead will attempt to fill in your space. I think drivers of automatics would benefit on their mileage by adopting this practice as well. Not as much braking and they wouldn't need to tip into the throttle as much to overcome the torque converter stall speed to get moving again.

[@ryanheckroth1802]

I just made a trip from Bend to Portland, and managed just under 38 mpg in my crosstrek. Driving under 60 had the most impact, and slowing down going up the mountain passes helped the most

[@HennaKyu]

I have a 6-spd manual 2020 Crosstrek. I have manually calculated fuel economy just about every refueling, I have kept tire pressures, engine oil levels (Subaru branded 0-20), and coolant levels at optimal, and only used 87 fuel from Chevron - My Crosstrek has gotten 40-mpgs on a few long distance commutes. I like to use the mpg gauge to also keep track of engine load during cruise-controlling, especially in hilly terrains, and during hill-climbings. Fast take offs can easily bring the mpgs down to about 22, and can likely increase engine and component wear. Also, steady (not pumping) throttle operation can help with fuel economy - a little extra thinking ahead can make a big difference in fuel economy. But most importantly let us be kind to one another - courteous driving habits can not only make driving experience easier and safer, courteous driving can improve traffic flow and increase mpgs. 🤗

Same here, 2018 Crosstrek manual… avg 38 mpg + w non ethanol… only use it in my motorcycle and all yard equipment.

[@lawrencecavens5760]

One thing to keep in mind is your battery health, don't forget the alternator spins 3 to 4 times faster than the crank pulley, which if you have a weak battery will increase the drag of the engine itself. you'd be surprised on if you disconnect the regulator while the engine is running while the battery is weak how much difference of engine speed there is when it is under load of charging the battery. In other words electrical load plays a role to fuel economy here too. So a good battery thats strong and healthy is important too.

[@sergeyafanasev7505]

It's a bad idea to disconnect regulator while running engine because of electronics in any

[@letsRegulateSociopaths]

I added an incredible amount of mpg when I replaced my battery (it was very old). Went from 28 back up to 36.

[@andreahighsides7756]

The crosstrek alternator is supposed to vary how much it charges depending on the needs of the car to increase efficiency

[@eswillie]

One thing I learned many decades ago when I had a VW Bug.......there's a thing called "balancing speed" which simply means that you accelerate firmly but gently to just above the desired speed and then back off gently until you can maintain that speed with minimum pressure on the gas pedal. You can see the difference these days with that mpg gauge, but back in the day it was just seat of the pants feel. It works. And don't let me get started on the backstory to the ethanol "mandates"; inefficiency and excess engine wear cost us all more in the long run, and we'd all do better by eating more corn. Lol. I actually get better mileage and lower overall expense (and better performance from that boxer 4) with the top octane fuel, despite the astronomical prices.

Wheel alignment and balancing also makes a huge difference, as well as tire pressure that you mention here.

I got a $45 dollar ODB2 scanner/monitor off of ebay. It tells you temps, duration of drives, speed, throttle position, and most importantly, km/L. Driving by trying to get the highest Km/L (while doing just shy of the speed limit), I went from 28.6 mpg to 30.6 mpg at the pump, with my 2018 Forester, base model, 2.5L NA, 6MT, 54k miles. Cleveland Ohio, 60 miles round trip to work Mon-Fri, highway 70% of the route, slightly hilly terrain. 7% better MPG means gas is 7% cheaper. Even 28.6mpg is on the far right side of the EPA MPG bell curve. Power when I need it, fuel sipper when I don't.

2019 Legacy FB25B, CVT; I'm averaging about 35.5-.6 combined right now; at my previous job with mainly highway driving and no stop and go at traffic lights, I was getting 38.2mpg last summer. 87 octane primarily, nothing lower. Do your maintenance, don't abuse your engine, and I don't try to drive it like it's a performance car. I'm getting bout 580-600+ miles per tank right now, but that's swinging so much because we're going from 80 degree days to 50 degree days in the space of 72 hours here in Wisconsin right now. Average with steady warm weather is about 620 miles per tank.

[@ussenterncc1701e]

Of note regarding the AC. It is more fuel efficient at higher speeds to run the AC with the windows all the way up, than no AC with windows down. The particular speed at which this crossover happens depends on the conditions and the aerodynamics of your vehicle; but 40mph is probably a good bet.

[@OutsideTheTargetDemographic]

For those models that come with it, learn to drive by the "% throttle" gauge, more than the speedometer. The SLIGHTEST raising of your foot off of the gas pedal can make sizeable differences in overall fuel efficiency.

Yep Robert they increase the ethanol to about 15% nationwide I believe I measured it out here in California and it’s as high as 17% at certain stations Chevron seems to have the lowest ethanol variant and maybe that’s why I get better gas mileage all the time at Chevron versus Arco or Shell, just a month ago I was helping my dad with his chainsaw cutting wood he lives up in the hills and we let the two cycle sit for over a month and when I came back after that month to help him again we couldn’t even light off his Sthil, The only thing I can think of is the octane decreased rapidly, I talked to my uncle he’s a engineer at Valero and he was saying that when you let the car sit every week you let the car sit you lose octane rating by one point !

[@leslielucci3182]

Dems keep preaching “ green new deal” but it’s actually dirtier (24%) to plant and refine corn into ethanol and burn it in your engine than to drill and use regular gasoline. Especially in the summertime, ethanol creates more smog that’s why the summer time EPA limit for ethanol was 10%, but Biden wanted to override that for E15 which in the end will reduce your mpg. All their policy changes seem a more expensive way to pollute more. Older engines (pre 1999) are not designed for E15. No telling how much faster the engine life will decrease by using E15?

[@timangie4538]

I have to totally agree. Since February our Model 3 has been out of service and wife and I are back in our 2016 Outback and we get about 600 miles per tank but, I use cruise control and drive the speed limit.

[@John-rw9bv]

The cruise control is not actually the ideal for saving gas, which comes as a shock to many people. This is because the engine is most efficient (Break Specific Fuel Efficiency) are 2700-3500 rpm, and moderate load/torque. In otherwords, when the engine doesn't have to make much power, it wont, but it's also a lot less efficient than when it's asked to make close to it's maximum amount of power. As such, the most fuel efficient way to drive a Subaru is to get as quickly as you can from 1st gear to whatever your top gear is, without going above 3200rpm, and always be either accelerating (moderate load) or coasting, ideally with the engine off. This flips the fuel efficient driving paradigm on it's head, because keeping the rpm low and consistent is something you'd never want to do driving this way. You want to quickly get up to speed, then coast/engine off, until you need another burst of speed. This is called "pulse and burn" hypermiling, and can see an increase in efficiency over 50%.

A couple of guys are saying that removing the charcoal filter (in the air intake box of a Crosstrek) not only adds to performance, but dramatically increases fuel economy. ...Air flow and all. It's job is allegedly to keep any gasoline fumes from escaping back to atmosphere when the engine is turned off. That filter is built onto the air box, on the MAF side of things. It can be cut off, but replacing it requires either buying a new half of airbox (if Subaru sells just one half- they don't sell just the mount for the sun visors for when they start falling off while driving), or perhaps gluing it back in place with silicone adhesive or similar. One thing about removing it is that it voids a new car warranty, if that's your situation. Another issue about removing it might be that it's another filter before air gets into the engine. For us, there are seven miles of dusty dirt/rock mountain roads before pavement. I change the air filter every other oil change, not 15-30,000 miles as recommended. The replaceable air filter is pretty dirty by that time, due to driving conditions. The charcoal filter surface is pretty gray at this point (155,000 miles) instead of white. I vacuum it out with a shop vac, and I can see some light through it when the MAF sensor is out for cleaning. It gets small leaves in it's face, so I know other stuff is getting past the main air filter. In our extreme situation, I haven't removed the charcoal filter, only because it adds another coarse level of protection..... but if removing it could improve economy for others, it might be something to consider. ...with 155k miles and running winter tires all year, we still get 32+ mpg most of the time. Compared to new cars, that's not super great. My Tacoma gets 17-18mpg, so getting over 30 is great.

Pull a bit over 29 highway, 25 combined EZ30 5eat, never use I mode. WiWilling to bet $100, full tank 93 100% gas or $50 and my choice of hideous rear window bumper sticker that says, I LOVE AAA.

[@ShawDAMAN]

Lots of good basic sense here. I average 28mpg in my 21 Crosstrek sport, in mixed driving. All things considered that is more than reasonable in my opinion for a high clearance AWD wagon. And that is with the loathsome auto start/stop feature turned OFF haha. I employ many of the tips you offer here. Anticipate and coast, especially. You'd be surprised how far the vehicles momentum will take you with no throttle input especially if you read the terrain a bit. Edit: I would add... I have the crossbars installed on my roof rails, and I do not plan on removing them 😆 still getting 28.2 though

[@frankweathersbee2553]

Same here around 26 to 27mpg, on road trips even going up to the snow freeway gets 33 to 34 average.

[@williamdwilson7366]

all good advice here on Long Island most drive like gas is $2 a gallon. I use Kirkland 0-20 synthetic, 87 octane , Costco. I get 34-36 mpg in my 48 mile trip to work. 55-60 mph first 20 miles then its dodge ball driving 60-70 depending where I can hide. the return trip at 230 pm is slower due to congestion so32-34 mpg. 1500-2000 rpm range. sweet spot

[@w5glsgary919]

2018 outback: 28 mpg with corn juice infused gas , 31 mpg 100% gas .

[@wwisaacson4807]

We traveled from Minnesota to Utah. There were times when 87 octane was not available. We had a choice of 85 or over 90. I realize that 85 will work in high elevations but, when you are on a trip you are not necessarily staying in high elevations and I don't like engine knock. Like you we did get some tanks with higher mileage with our Crosstrek.

[@EdAtoZ]

Mr Subaru 1967, Got my first Gedore "Red" item today #R40170027 Bit ratchet. It is their auto locking flex1/4 square drive ratchet converted to a 1/4 bit ratchet. Been playing with it today and the 72 tooth action seem very good, the Head is a full size head. For now $38 it seems a great buy.

[@HallucinatingHell]

Adding on to the more diluted fuels/gasoline try out some injector/fuel tank cleaners will also help with better mpg

[@tbas8741]

Regarding Coasting like down hill. Dont put it in nuetral tho then will use more fuel when left in gear and coasting down hill with foot off the gas injectors are almost shutdown only enough to keep engine from stalling. In nuetral it pumping now idle fuel flow (which is really bugger all Idling for 10 mins you can drive about 150-200ft on that fuel used)

[@kazriko]

Robot Cantina did a test of the fuel in Kansas. They found that the 87, 89, and 91 fuels were all under 6% ethanol, but the 93 octane was 22% ethanol there. So far here in Colorado, I've been pretty much steady at 16-18mpg since I bought the car. I buy non-ethanol most of the time though. The non-ethanol costs about 20-30 cents per gallon more here than regular 87 octane.

[@bbodan5393]

I don't believe that one because they only pushed 87 and 93 octane gas through the pipe in Central PA over 25 years ago. Everything is derived from them.

[@GeorgeENorkus]

Everything said is pretty much very good except one and that is when you said opening your windows. Modern autos are designed to get maximum fuel mileage with them closed When driving and you open a window, the air flow changes causing wind resistance, thus lowering mpg. I don't know how true it is but I was verbally told that you waste more fuel with lowered windows that it takes to run the air conditioner. Also, with modern air conditioners, you it only takes about 1/2 mpg. As a side note, some low powered cars will actually turn off the air conditioner when accelerating from a light or passing.

[@Databyter]

Another thing I realized recently, was that in trying to reduce my AC use, I was opening up all 4 windows and my moon roof. And I love driving around like this. Yes, it is not as cold as the air conditioner, but the refreshing feeling of all that wind is competing, even on a very hot day. But I found that my MPG was suffering and I didn't know why. I had a moment of clarity and realized that all the times during which I was driving my car around fully open, my MPG was a few points lower. Especially on surface street driving where I mostly do it, since driving with windows open on the freeway gets sketchy sometimes. But when the windows are shut, even tho I need to use the AC more on hot days, my mileage can actually be a bit better. And I believe this all has to do with drag. Just like ground clearance. If you have open windows and moon roof, all those openings are creating air currents that work like airbrakes to the air in front of you trying to get past your car. All the wind that is coming INTO your car has to get OUT. and that pleasing pressure that you feel on your body, IS PRESSURE, and it is also resisting your car moving thru the air. So it is BEST to have your windows rolled down, and AC off at LOWER speeds where you can actually maximize the benefits without as many penalties. Once you get up above a certain speed, like above 25 mph, you are better off closing at least some if not all of your windows, and of course if all of them, or enough of them, you are going to need that AC to be on again, but it will be worth it in the way you cut thru the air more efficiently, which all things being equal makes much more of a difference to MPG at higher speeds than the drag to your motor caused by the AC pump.

[@TubeBrowser2]

I have a manual trans Crosstrek and shift below 3k rpms. Helps mpg a little.

[@chriswalker4272]

Thank you for the eco tips. Adding reddex fuel system cleaner can help keep injectors clean, which helps maintain a finer mist of fuel delivery and thus power and mpg. But my Subaru XV (Crosstrek), is a 2.0 turbo intercooler diesel in Scotland. I get 30 mpg towing a small caravan, and usually over 50 mpg highway and 37 to 47 mpg urban. It's ULEZ compliant and Euro 6 without any additives.

[@markmalinowski5951]

My 2013 crosstrek is doing the same with MPG as yours. I also notice when I drive in the mountains in thinner air my MPG goes way down.

[@yourghostisagift]

One of the best ways to save gas is by not accelerating fast/hard. I try to tell my family this but it seems they forget instantly. I watch so many people speed off the line and watch them waste so much gas

[@timnichols3582]

I wish there were as many (independent) Subaru mechanics like you out there as there are Honda and Toyota. It would make it so much easier after your new Subaru goes off warranty. If you're ever in Hampton Roads Virginia you can work on my 2022 wilderness forester for your channel.

[@s2meister]

AWD a "hindrance" HA Yesterday it was 85, today it is snowing. In Wyoming we call that "Friday"

[@moonwolfe4361]

Mr, Subaru big fan man, lots of useful info, I have a 2014 impreza hatchback, 5 spd manual, it has a very intermittent sputtering problem when I do a cold start up. there's no power loss whatsoever, very small puff of white smoke out the tail pipe, when it sputters, very intermittently. oil looks fine, with no loss, coolant looks fine with no loss.

[@moonwolfe4361]

The devil queen thing is my stepdaughter btw, lol

[@MrSubaru1387]

My 2013 Crosstrek does the same thing.

[@rossinzana4175]

My first car I ever bought was a '95 legacy hatchback and it used to have a fuse for the AWD, could pop the dude out and it would be RWD. I miss that

[@grumpy1311]

Wife's Forester , since new in 2012 has demanded Super gasoline or the car does significant "pinging" detonation under load. Even new it was pretty significant. Now with over 200k the car still runs well... but running Super is ... expensive to say the least presently

[@lateral1385]

Dropping $80 a tank 💰😅

[@grumpy1311]

@@lateral1385 yup! I got in wife's car other day and it was on EMPTY.. I was filling it up and the pump was going sooo slow , I sat back in the car... then the pump clicked . I got out and noticed it showed 12 gallons.. and only $6.30! They had mis priced Super @ $.55 rather them $5.55! I had to tell them because I really didn't think it fair the manager have to deal with that. Cheapest fuel I have ever bought! ✌️

[@don-cw1yz]

Old Subaru's used to have a switch in the engine compartment that allowed you to select 2 wheel drive or AWD modes. I Wonder why they stopped doing that? Makes sense as in the summer if you are mostly on paved roads 2 wheel drive would be okay and the vehicle would use less fuel.

[@graemethomas1347]

I do agree little savings all add up and here in Australia with fuel at $2.15 + per Litre ( 4.5 litres per gallon) and finding out a lot of it has been contaminated with water witch is just great for your car NOT so yeah every little bit of saving fuel is going to help with everything else that's going through the roof.

[@shendogman]

Good tips! I've actually been running higher ethanol fuel in my Crosstrek. E15 is typically 30 cents less per gallon, and mileage only drops by 1-2 MPG. This may be related to what mrsubura1387 was saying about E10 containing more than 10% ethanol.

[@cbijames7]

Non-ethanol fuel will give you better gas economy about 30 to 40 mph more per tank

[@jermainemorgan171]

Well said, all these characteristics will help within this high rises in fuel prices.

[@7795Dakota]

Love you content! I've learned alot for your videos about boxer engine's. You video about changing spark plugs helped me out alot.

[@Rio97621]

Changed my air filter and got a mpg boost. More power too

[@Modeltnick]

All good suggestions! I’ll have to remove the roof bars and see if it makes a difference. Also, I noticed more spark knock with the regular grade unleaded recently. I switched to mid grade and the pinging went away as well as have gotten better performance and fuel economy!

[@sandy_knight]

Yup, 100% agree, all good suggestions. Good to see no mention of fuel saver magnets, the science on them is unproven (and that's being kind).

[@sergeyafanasev7505]

Mine best was 6.8l/100km (about 34.5mpg) at 210km trip after sparkplug replacement, oil replacement and new air filter. Best on full tank was 760km - this is mixed, city plus highway. FB20 Forester.

I have a 2013 crosstrek, no mods, 0/20 oil, and I’m down to about 22-24.

[@critter3188]

I’ve had my car gone over by Subaru mechanics, local mechanic, and on my way to an actual trustworthy Subaru owner, mechanic. Not even..100,000 yet and have dumped over $4000 in suspension. If you folks buy a crosstrek for climbing anything, you better be prepared to replace all your bushings, brakes, rims … I can go on forever. I did nothing but drove on Ohio roads. If it can’t handle potholes, how well will it be a climber. Also rust protection is a joke. I’ve had mine rust protected from the start. Bullshit

[@boranzhao3042]

2018 Outback limited, living in MN, summer mpg about 29 combined; winter is about 25.

[@patgarrett3746]

I have a 2022 Outback and I've been averaging 35 mpg. I've found that I get the best mpg at 61 mph. On the interstate, I still get around 32 mpg at 72 mph. Also, weather plays a big part in mpg. Cold and windy weather will really lower the mpg. I also get noticeably better mpg when I use a non-ethanol-containing blend of gasoline. I've found that 87 octane non-ethanol gas gets me better mpg that 91 octane non-ethanol gas. They keep adding more ethanol to our gas because the government pays blenders 45 cents per gallon of pure ethanol they blend with gasoline. Thats a good incentive for them to keep sneaking in more ethanol to our blended fuels. It costs more for non-ethanol fuel, but I get at least 5 mpg more with it.

[@larrythiry157]

I have a 2016 Legacy with 107,000 miles. I get about 32 mpg with everyday driving and as much as 38mpg on the highway.

[@saxonaus0010]

Best I've got in my 2015 XV is 6.8L/100Km. With the roof rack on over the same 350Km journey it jumps to 7.8 well worth removing roof racks if you done need them.

[@LDU2U]

The only thing I forgot when I bought my Tribeca is the bloody spare wheel, that wheelbarrow spare is utterly ridiculous here in Australia, so, I have to take a bloody Subaru spare with me in the back for long distance - weight - and we do have the odd kilometre between towns. The first thing I did when I bought the vehicle was to remove those 'surf racks' on the roof. Most other things you mentioned is what I have been doing. Also, I upped the oil as well, the vehicle has done over 150 thousand km's, so I figure as the engine wears over time, it was time to up the oil a little, but, I do believe the oil has increased fuel consumption a little. But, I NEVER use that Ethanol crap. I had researched that and found it was not that good for the motor, after listening to you I was correct.

[@GeorgeENorkus]

Concerning the type of gas and the MPG. in over 4,000 miles of driving I have found that gas stations that own their very own refinery and use their own trucks to deliver it to the station, provides a better quality of gas. I found that Shell and Mobil are two of the better.

[@shrimperlincs3395]

In the UK standard is 95 Octane, which is 10% Ethanol (E10). Supreme is 98-99 Octane and 5% Ethanol (E5). The MPG drop when moving to the newer E10 95 Octane fuel is about 10-15% lower fuel economy. Oddly the Supreme 99 Octane is only about 7-10% more expensive, so Supreme is the sensible choice at current prices (July 2022).

[@tjonesauto]

I noticed my 2012 Outback has a sweet spot for takeoff of around 1700-1900rpms and cruising around 2200-3000rpms. Hitting the gas hard revs the engine and wears the CVT.

[@grandtheftauto1233]

I got 400 miles to a tank in my 02 NA Bugeye with the ej25 Lot of sensible acceleration and coasting, only going 67mph max or less if I could. Drafting as possible. Was a really good tank! Haha

[@letsRegulateSociopaths]

my 2012 impreza manual transmission gets 32 COMBINED, 36 plus highway. Actually I bought the car for free when I considered the fuel cost savings (I drove a 100 miles plus per day).

[@Day-Cab]

My 06 non turbo impreza 2.5 w/5 speed manual transmission likes oil. I made a trade off using ... 10w30 synthetic oil + schaeffer moly EP additive. It slows the oil burning. Not going back to stock recommendations for oil viscosity. Better fuel is a option. But I live in a small indiana town & choices are fewer.
