[@flagmichael]

I agree - this is some of the best science I have seen on the 'net in years. I love the clear statement of what is being tested and especially the data gathering. I would have cast out the one outlier (especially since we are looking for what we can expect) and would have expressed the changes in percent instead of mpg because one mpg means a lot more in a Ram than in a Prius, but we have the data available to do just that. When we convert the data to percent, we see the second to the last (Big Guy Review) is also a bit of an outlier, at 14%. Probably the same effect Chris surmised - the injectors needed the cleaning. With just the one outlier removed the average change is +2%, with both dropped from the list the average change is still within one point.

[@tjwtrumpet]

Chris, I've recently discovered your videos and all I can say is "WOW" and "THANK YOU!" I recently purchased a 2002 Honda Accord SE with 196K miles, and your vids have been very helpful with me fixing the few things that needed work on the car. I used to have a 1994 Saturn SC1/5-speed. Bought it new, and it was the best car I've ever had. Sadly it got totaled when I was the middle of a 3-car accident (234K miles on it). I am an easy driver, doing mostly highway miles in the LA area. Averaged 26,000 miles a year or so. My mileage would be anywhere between 27 & 32 in town, upwards of 37 mpg on a pure road trip. I would try different fuel cleaners, usually Gum-Out, adding it every 5,000 miles. Whether they really helped or not I never knew, but I figured what the hell, it's $5 - 7 bucks, what could it hurt? Anyway, about 15 years ago and with around 160K miles on the Saturn, I tried a fuel additive that I found in a WalMart that was made by (of all companies) Turtle Wax. I forget what it was called, but it was some fancy/exotic name, and cost about $10.00 Added to an empty tank. Filled up & got my usual close to 400 miles on a tank of gas. BUT...after running that one tank, my mileage increased tremendously! In town was now always over 30, and road trips were between 39 & 42 (my all-time high)!! Started using it every 5,000 miles. After running a tank of gas, the mileage would shoot back up to the high numbers. Told all my friends about it, and they got similar results. And suddenly, around 2004, it was no longer available. I contacted Turtle Wax (letters, email, phone), and never got an answer as to why it was off the market. I'm not a conspiracy theorist but who knows - maybe the oil companies bought it out & killed it... I wish I could remember the name of the product. And I wish it was back on the market. Thanks again for the great vids & all the best to you! Tim

Throw out the one obvious outlier, and you get an average of 0.48 increase in MPG.

[@wholeNwon]

+anti0918 Discarding the obvious outliers at both extremes is exactly what should be done. If the improved mileage is due to cleaning injectors, that improvement should be sustained for some period of time thereafter with subsequent tankfuls not containing the additive. I think that those data would be interesting. My guess is that the small improvement in fuel economy will be promptly lost. Perhaps Chris can contact his testers and ask them whether improvement was sustained.

Greg Snyder I certainly don't think that Chris is trying to plug a specific product at all. He fully disclosed the Volvo figures and pointed out the deviation from others. He also repeated that he saw no benefit in his own car. So, if that's a commercial endorsement for his own profit, it's certainly a very unconvincing one. I sure wouldn't use the stuff in my car.

[@sniperlif3]

bahhaziz I did not mean to say speed, meant power(as in seat of the pants feeling).200hp moving a 2000 lb car vs 210hp moving a 2000lb car is 5% increase. If you change 10 hp in a 500hp car you won't feel anything, less than a 2% change. Of course weight factors in making the overall power feeling less than perfect word power.

Doing a t-test (used to compare sets of data) of the 20 entries on the data sheet, and there is a 73.2% chance of the difference being due to random variance. Also, the standard deviations is much larger than the difference between the averages, which usually indicates that the difference is due to random variance (though in this case it is also due to using different cars).

Great video. This is about the best REAL WORLD test I've seen. It's not some controlled lab test on some closed track with no traffic. Driving the same car with the same driver. We all live in different parts of the US. With different weather conditions, cars, traffic conditions. Drive patterns and drive styles. A lab might "replicate" real world conditions but it doesn't beat the real thing. That is the reason a car might go 400,000 miles in a lab without any issues but will struggle to make it 100,000 miles in the real world. A lab might duplicate the real world but it will never be able to truly be the real world.

[@ushyamamoto7098]

1mpg for how much money? I highly doubt the price of the increased fuel economy was enough to justify the additive price.

[@CubyDoesStuff]

madjimms it is probably made for slower cars

[@jhonjohnjonjondoe5011]

remember it did increase horse power a good bit which would make me think this test is inconclusive and use my head that it does increase MPG. Lets put our thinking caps on and realize increased HP means less straight on the car to pick up and if you drive it the same mpg should go up.

[@runemage9008]

you can buy one bottle that treats 480 gallons for 37.41, so if an average car gets say 24 mpg, that's 20 gallons you saved by the end of the bottle, and depending on where you live that can be upwards of 40~60$

[@johnhandcock3242]

Except, the outlier wasn't thrown out. The actual avg was like 0.5 mpg, and even that might be due to random variables. I suspect it does help improve mpg an incredibly small amount, but only because it helps clean your system. After your system is cleaned, you don't need to add more of the additive in it to see that small benefit.

[@milanvermeersch8281]

@@runemage9008 In the Netherlands 20 Gallons is way more than 60$. 1 US Gallon = 3.7 LITERS, I pay 1.60 euro's (AT LEAST) per liter, so it's like 5.92 euro's per gallon, times 20 = 118.4 euro's saved, or roughly 130 dollars. I'm definitely trying this stuff.

[@issacbourne5111]

When it comes to a fuel additive increasing mpg, there are things to consider on what the additive actually does. What can increase mpg in a fuel additive? 1) Reducing upper ring friction. The top ring does not get much lubrication. So having something in the fuel additive that reduces this friction can increase mpg. Also injectors that are not metering the fuel correctly due to wear can benefit from this also increasing mpg. 2) Reducing the surface tension of the fuel. This allows the fuel to atomize with the air better. If your injectors happen to have a bunch of mileage and they do not even have to be dirty. They can benefit from a fuel additive that does this 3) Increasing the burn temperature of the fuel. Not the ignite temperature but the actual burning temp. Increasing this ensures that more of the fuel burns and a more complete burn 4) Raising octane. Octane is the fuel's resistance to burn. Which on a poorly tuned car corrects the computer retarding the ignition timing to compensate. So according to what your car needs determines which type of additive will increase your mpg. Example: Chris used a Vette. Vettes are known for having precise fuel metering injectors and computers programs to control it. This is to get the most HP while also getting the most mpg. So because the factory focuses on this with this car I suspected when Chris used it in the test that we would see no increase in mpg. So what this tells me is that this fuel additive is probably a surface tension modifier that better atomizing the gas. So on cars that do not have this problem, it will basically do nothing. But cars that need help in this area, it will seem like an answer to prayer as a car can probably get anywhere from 3-5 mpg when atomization is the problem and the additive becomes the fix.

[@chrisfix]

+Ron Aiosa I try to get my subscribers involved!

[@wtfiswiththosehandles]

This pretty much proves it doesn't work. 4% difference in fuel economy is next to nothing, and could be attributed to different driving style when using additives. Not to mention it would be worse if you didn't take into consideration top and bottom results (11mpg increase... yeah) Your test in a corvette also doesn't prove anything. Even slight wind can change fuel economy at highway speeds, so you may have been driving down and upwind when you drove in two directions. Only test that could prove anything would be a synthetic test with motor on a dyno. That's the only way to remove variables.

[@RGV2300]

or with cruise control.

[@jason2709]

I agree

[@schlafanzyk]

cruise control makes it worse, because it will keep the speed exactly the same and you don't even notice the effects of wind or hills on the throttle position, because the throttle control is completely out of your hands. that effect also decreases fuel economy overall when using cruise control instead of manual efforts, because the car prioritizes holding constant speed over constant throttle position. that's fine in a completely neutral setting, but as soon as hills, wind or other environmental factors play into the mix, cruise control performs very poorly as far as fuel economy is concerned. it's just about convenience.

[@fargeeks]

+schlafanzyk Well of course it doesn't do well with hills because that is where the engine will change rpms just to maintain the same speed revving higher or lower

One problem though is you don't know if everyone was using the same method to calculate mpg, could have been a lot of errors and variables depending how they were calculating( at fill up etc, using the mpg on their dash if applicable, or just arithmetic error).

Pretty cool collaboration!

Fuel additives do work but they aren't miracle workers They mainly clean fuel lines, injectors and combustion chambers If you use good quality fuel, don't do too many short journeys or if you do occasionally take your car for a longer drive. You will find that your car on the whole has pretty good fuel economy. However if you use low quality fuel, don't service your car frequently and do lots of short trips. Your fuel economy will suffer. I use a fuel additive 3 to 4 times a year. I use good fuel and I do some longer trips but I find that the additives help. I have a 12 ref 1.6 TDCi Ford Focus I average 53MPG I find my MPG drops to around 47 MPG prior to using the additive. I use the additive in accordance with the instructions and usually when I'm doing a long journey. My fuel economy always returns.

Edward Trickett i didnt do highway testing but i average 18mpg in my 08 jeep grand cherokee in the city/country after i used chevron techron. Before i was lucky to see 16 mpg so the techron definetly did clean some stuff up inside. But my car gets a rated 17 city anyway lol.

[@SalveMonesvol]

My conclusion: at least 1 bottle is totally worth it.

[@chrisfix]

+SalveMonesvol I agree. You can get their cheap bottle that is good for one tank and see if it actually works. Worth a shot!

[@SalveMonesvol]

ChrisFix Ah, the nice acknowledgement of existence when the content creator replies to you ;)

[@NineS5]

should you drop the hood rather than pushing it to lock so that you dont cause any dents?

[@chrisfix]

+Nine's And AK's Gaming Channel depends on the car.

[@splash5974]

Wont dent the hood of that Vette! 😉

[@sugarnads]

Whats gonna dent it?

[@darrylbooc1196]

As an automotive enthusiast and a college student with units in statistics, I am really impressed

[@agvs]

You know Chris, I have been following you for some time now and I don't know if you will read this but I greatly appreciate you making these videos. I remember when I didn't have my driving license yet, I was watching your videos and it greatly motivated me. Now that I have my license, I feel like a child in a candy shop. I appreciate your way of speech, the manners you have and the mindful approach you take. My compliments for that. If you have any tips for new drivers then they are more than welcome. Thanks a lot, greetings from Europe.

[@playzfahdayz]

Lol, 11.4 mpg increase for one car at the very end. That's called an outlier, and it totally ruined your analysis... Real Summary: This stuff is useless.

[@DENicholsAutoBravado]

I think it's worth testing again. A statistician worked with the data. I read a lot of notes from either statisticians or people who have taken the class, or better, and once you throw that test out, there's still a 0.54 average increase.

[@Timfield.42]

hey chris let me know if you need anymore testers for stuff! id love to help

[@chrisfix]

+General field Stay tuned because I will have an update video in the future asking for help. I have a ton of cool projects I want to do.

[@ruanjiayang]

have you ever considered that fact that the additive itself takes some volume in the fuel tank?

[@chrisfix]

+Jiayang Ruan you use 2 oz every 30 gallons

[@ruanjiayang]

yep, just for your reference of rigorous statistic, this is science

[@ruanjiayang]

plus, we have to also consider the money we paid for the additive. What we care is the total cost per mile, not only the fuel, right?

[@kevinkainzbauer267]

I have my own experience with fuel system cleaners. I used Wynn's Petrol treatment on my 1994 Mercedes E-class petrol. It was sitting for about 3 years and it startet on the first try, so not like your driftstang ;-). But the gas-mileage was pretty bad for a four cylinder. About 12.5L/100km (18.8 mpg). I used the earlier mentioned additive and it worked pretty well. Under similar conditions, my Merc uses about 9L/100km (26.1 mpg). So that's an increase of ~28%. That's pretty amazing. I just want to say, that you're awesome ChrisFix. Keep doing! Greetings from a new fan from across the pond (Vienna, Austria)

[@mustafawali4488]

That is one of the cleanest Corvettes I've seen.

[@Striball]

Mazda Miata clip in the video but didn't run the test of the additive?

[@chrisfix]

+Striball what?

[@Striball]

+ChrisFix 3:00 a Mazda Miata is the car but I guess it's for the purpose of filming the Jaguar in front of him, just noticed this. Just kinda odd the shot is of a Miata but didn't show in the spreadsheet.

[@chrisfix]

+Striball Oh, I think he sent me the footage of his Jaguar in front of the miata.

[@hatehereyes]

+Striball Yup that's my friends Miata. He wasn't part of the test but we do canyon runs together.

[@reanderson10]

All that for 1 MPG? No thanks. Basically it's useless.

[@DENicholsAutoBravado]

0.54 once a statician through out the outliers actually. If you drive 5,000 miles ever month or so that's like a $15 dollar savings and those bottles treat up to 460 gallons, so it really will save you your money (assuming in the last 3-4 years the product hasn't changed).

[@wyattmccomas5238]

Hey my dad has this corvette except my dads is a wide body

[@chrisfix]

Nice!

[@victormendoza871]

i realize this is very late but we all need to remember tires will be a variable the pressure the remaining tread ect.. i love these videos i work at a auto parts store and it helps me to be honest when customers ask me what to use . so far i like the royal purple im going to use it in my 03 ford taurus and 03nissan altima both v6

[@NotAnArsonist94]

Chris you have one of the most informative car videos hands down! I'd love to see one about fixing wheel bearings and how you know when you should fix them. Thank for the vids!

[@miguelelelelel]

Love the concept of this video, how you broke down the data, and even included some subscribers. That’s dope!

[@BlacklistMotorsports]

Really love seeing a well kept C4, being a new owner of one myself, it really shows how nice these cars can be!

[@chrisfix]

Thanks! What color and year is yours?

[@BlacklistMotorsports]

ChrisFix 1990, same color as yours, but a tan top, tan interior Convertible with 74k miles. Thanks for asking!

[@jeffreygammel8950]

[@ECxPassion]

I had a lifter problem in my V8 5.3L 2007 Chevy Avalanche. I didnt have the money to fix it right away so it sat for about 5 months. When i finally fixed it I dumpped the old gas and put in fresh gas but the Fuel Economy was way lower I put in a total of 2 bottles of this additive in about 2 weeks and it improvved it for about 5 miles per gallon.

[@chrisfix]

Awesome!!!

[@btaskoy]

I love this channel. I don't even own a car and I drive my dad's car when I need it, but you have saved my ass from getting a rebuking several times when I scratched the car. So Thanks!

[@shaggysmurf4422]

I like this channel. This is a nice channel. Seriously, I can't trust ANY mechanics where I live. Complete scams. So it's nice to know people are willing to share their knowledge with those of us who aren't afraid to pop open the hood. Respect.

[@xinic5]

+Toad Kinopio Years ago I took the truck I had at the time to a mechanic who when pulling the truck out of the garage to "hand over" to me after finishing working on it, he told me he could fix the broken door handle for $50. I asked how hard it'd be to fix myself mostly joking, and he actually started giving me instruction (though quickly) on how to do it, and that it was really simple. After this I kept taking my truck there. He even fixed it a few times and let me take it with me without paying, without holding anything to insure I would come back. He just trusted me as a frequent customer to return and pay what I owned him.

[@ellesmerewildwood4858]

Awwwwwe I love your Corvette Chris. You don't see too many of those downunder and yours is so pristine. Kudos for keeping it so beautiful. As for the fuel additive, many products I see on youtube available in the US aren't available here, so for what it's worth, as a brand, I like "LiquiMoli".

[@89elmonster]

I just got my first ever car and I an currently 17 years old, I got a 2002 acura tl type S 6 cylinder 250 horse power. And I love it she's me baby, and I've got a few problems with her but I'm trying to fix them, here are some: Power steering pump not working correctly, flat tires, bad breaks, all the interior leather is dry and ugly, back seats and front seats have alot of tear. and that's just a few but these videos are helping me and I thank you for that! =)

[@chrisfix]

+Jarmahent Awesome and congrats! I am glad the videos are helpful!

[@Fer-Serrano]

Como tu lo dijiste, es una comunidad desde muchas partes del mundo, saludos. great work¡¡¡

[@sbarua219]

I use a brand called STP every so often as a fuel additive. In my experience, I assume it's done its job but have never really been sure cause I never paid attention. I drive an 04 Accord EX V6. I told one of my buddies to try it in his Infiniti G35 S and it substantially helped him. So I guess STP (the red bottles I use the most) is good

[@sixfootdworf9545]

Ford Mustang V6 2013. I use STP 5 in 1 fuel system cleaner every couple months and use standard fuel with an STP octane booster. It does work in my opinion. I used to drive a Lincoln continental. 1997. That thing was a slow beast. 4.7L V8. Anyways, she had bad spark plugs, a bad O2 sensor, and the mechanic was concerned about the injectors... as well as a broken throttle body. Used the STP stuff for a while and I had significant Performance return, injectors were working like new again and the engine as a whole ran a bit better. After everything else got fixed the car ran like new of course, but ever since then I have been using these fuel additives in my cars. (Update on my car... sad news...) A guy pulled out in front of me and failed to yeild. I hit him at 50 MPH and totaled the mustang. Back to the old Lincoln until I get my insurance money.

[@hamzaben681]
