Car Forum / Volvo Cars / December 2005Fuel saving devices - do they do ANYTHING?
Just wondering if anyone here has tried fitting fuel saving devices to their car (magnetic clamp onto the fuel line, fan blades inserted into the air intake, etc.) and if these actually did anything for fuel economy - or not. Thanks for reading... Allan. >Just wondering if anyone here has tried fitting fuel saving devices to >their car: > (magnetic clamp onto the fuel line, My 240 had one of these on it when I bought it.

I've used them for years, and for the decade or so I was coming home at 4:00am (a peak time for deer and other animal activity), they turned lots of critters away from my path. Sometimes they would spook them out into the road, but it was always well ahead of me - I never had to lock the wheels, or even brake hard. A big improvement over having deer run out 10 feet in front of you, in either case. They are useless in the case of amphibians, though.

They are useless in the case of amphibians, though. Deer whistles were a hot topic in our department a year or two ago. We never reached any sort of resolution - we could use them if we wanted or not. The "antis" pointed out that the frequency is so high (1/4 wavelength is way less than the deer's ear spacing) it is impossible to tell which way the sound is coming from, and that deer have no way of deciding what (if anything) to do. Your experience is the most positive thing I've heard. Mike > > The larger animal warning whistles do work.

The point is that the sound either freezes or spooks them while the car is still quite a ways from them.

They can't work! They create frequencies which cannot be detected more than about 10-20 feet from the car, and they are at frequencies beyond the hearing of the deer. We call them elephant whistles because no one in North America using them has ever hit an elephant on the road. My research on them was prompted by a personal event. They were mounted on my motorcycle and we were on a ride in the Sierra Nevades north of Truckee. I rounded an uphill bend and spotted an 8pt buck to my left is a wide area of the shoulder wh8ch led to a hill. To my right was a narrow shoulder and a substantial drop-off of great angle. Just as we got near him he bolted... RIGHT INTO OUT PATH! He could have gone away from us and up the hillside, but ran all the way across the pavement to go down the hillside. I hit the brakes as hard as I could and the thing passed in front of us- about five feet away. He jumped in the air when he was directly in front of us and I could see his belly. I got home and removed the whsitles and ordered something to warn off a far more dangerous and unpredictable hazard. I mounted Piaa-style fog lights to help cellphone-using car drivers see me! __ __ Randy & \ \/ /alerie's \__/olvos '90 245 Estate - '93 965 Estate "Shelby" & "Kate" > >> > The larger animal warning whistles do work.

Ok. I'd also like to note that there are at least three different types of whistle; the ones that I'm sure work are the ones with large, rectangular scoops, and the ones with *large* trumpet-like scoops. The tiny ones that look like little, well, whistles, are probably worthless. I have a set on my motorcycle, but have no idea if they work when mounted only about 18" apart.

I have a set on my motorcycle, but have no idea if they >work when mounted only about 18" apart. It was a rising corner and quite wide open. This was not the first time that a deer crssed my path with the whistles on. Regardless of what the anecdotal evidence seems to suggest one way or the other, please explain or supply evidence as to how a sound that is beyond the hearing range of the deer could have any effect on their behavior. There was a road test done with roadside microphones which showed that the whistles effective range at speed was about 6-8 feet as I remember. No very effective by any means- real or imagined. __ __ Randy & \ \/ /alerie's \__/olvos '90 245 Estate - '93 965 Estate "Shelby" & "Kate" it could be all "in the head" of the driver...positive thinking..you know....having an effect on the statistcal outcome on if you were going to "chase a deer away" with sound & frequencies......... > it could be all "in the head" of the driver...positive > thinking..you know....having an effect on the statistcal > outcome on if you were going to "chase a deer away" > with sound & frequencies......... I'm talking about two things, neither of which is subjective: how many deer (and other animals) ran into the road in front of me, and how far ahead, with and without the warning whistles. If I were saying the difference was one or two deer or a few feet, that could be subjective. Dozens of animals over the years, along with distances on the order of 25 feet, aren't.

They attach to the front of a car and make a high-pitched sound that is inaudible to humans, but supposedly frightens deer and otheranimals off the road. Some users love them -- they insist the devices prevent collisions. Despite their unwaveringloyalty, some researchers are skeptical that the whistles actually do anything." "Some researchers are skeptical" about just about anything. > http://www.ccefm.com/youth-development.html This is another case of noting no definitive evidence that they work. I heartily agree that driving skill is more important than a bumper-mounted whistle, however. In some cases, anecdotal evidence can be more reliable than field tests, especially when the field tests consist of things like counting deer/police car accidents, and blowing through the whistles. I'm not the only one who has observed that these devices can work; "The Deer of North America" by Leonard Lee Iii Rue, is regarded as a definitive work on deer. The author, who has been hunting and studying deer for decades, firmly believes that they work, because he has been using them and observing the results. So have I. Your results may vary, and I would definitely avoid the smaller whistles in any case. You can have the last word. Signaturehttp://freevision.org/michael/index.html ----------snipped from cnn this am------------------------ NEW YORK (CNN/Money) - Pennsylvania ranks first among the top ten worst states for vehicle-deer collisions, according to an insurance survey published Thursday. Citing claim statistics, auto insurer State Farm said that drivers in Pennsylvania experienced more deer collisions than any other state between July 1, 2004 and June 30, 2005. State Farm estimates that 1.5 million vehicles collide with deer every year, resulting in 150 motorists deaths and $1.1 billion in vehicle damages. With deer migrating and mating season occurring between October and December, the auto insurer says a higher number of deer are near roads this time of year. Coming in second and third were Michigan and Illinois, followed by Ohio and Georgia. Minnesota and Virginia ranked sixth and seventh respectively, while Indiana, Texas and Wisconsin rounded out the list at eighth, ninth and tenth. The insurance company said it based its rankings on the total number of deer-accident claims filed with State Farm and did not adjust for population. The auto insurer says that attentive driving is still the best deterrent for such accidents. In order to avoid such collisions, State Farm says drivers should use their high-beam headlights as much as possible to illuminate deer hiding on the side of the road and to not rely on car-mounted 'deer whistles,' which studies show not to affect the animal. If a collision with a deer is unavoidable, according to the company, it is best not to swerve, which could increase the risk of injury and could cause you to lose control of your car. There are a number of motorcycle clubs in the Northeast who are (were?) purchasing hunting licenses and ammo for hunters who cannot afford it in an attempt to lower these statistics as well (it was to hunt the deer- not the drivers).. I read somewhere that there are more deer living in the US now than there were during the Revolutionary War. >----------snipped from cnn this am------------------------ > [quoted text clipped - 34 lines] >is best not to swerve, which could increase the risk of injury and >could cause you to lose control of your car. __ __ Randy & \ \/ /alerie's \__/olvos '90 245 Estate - '93 965 Estate "Shelby" & "Kate" i live in colorado, but took a drive back to boston a few years ago....when i went through pen & that area...i was taken back by all the deer i saw along the highway...both dead and standing there l@@kin at the cars whizzin by...i saw a lot more than i see along the colorado and wy roads..... > i live in colorado, but took a drive back to > boston a few years ago....when i went through > pen & that area...i was taken back by all the deer > i saw along the highway...both dead and standing > there l@@kin at the cars whizzin by...i saw a lot > more than i see along the colorado and wy roads..... With the decline in farming in the Northeast US, because of geography, there area taken by woods has grown, and the deer population with it. Where I live, in Westchester County, NY, hunting is not allowed in most places because of the danger to people who live there.

Tips for avoiding deer 6. Deer warning gadgets don't work. McAninch says several studies have shown that whistles and other devices attached to vehicles fail to scare or warn deer: "People want to drive 60 miles per hour with some device to scare deer off roadways so they don't have to slow down.

They're 100% pure bullshit, they are guaranteed to work at emptying your wallet though. probably the best fuel-saving device is a good tire pressure gauge... use it regularly to keep the pressure up, and that will help reduce fuel use as well as prolong the life of the tires! I keep my 240 around 36PSI, which is a bit higher than the figure posted on the car, but I like the firm ride and tight steering. Especially important to check the pressure during the spring and fall, when temperature is changing almost daily! >probably the best fuel-saving device is a good tire pressure gauge... use it >regularly to keep the pressure up, and that will help reduce fuel use as [quoted text clipped - 4 lines] >Especially important to check the pressure during the spring and fall, when >temperature is changing almost daily! We have a 1978 244 - I *think* the tyres are supposed to be 32 PSI according to a label on the car. I can't stand it at that pressure - the steering is so HEAVY. I recently put 40 in, but the tyres were hot at the time, so yep, about 36 is usual for us too. They do great for the seller - transferring $ from your pocket to theirs. Other than that, nothing.

None of 'em work. Consumer Reports recently did a test of a number of popular types. Most did nothing, some did harm.

[ ... ] Until you consider that warming the fuel reduces the density of the charge going into the combustion chamber, therefore reducing the energy obtained when it burns. That's why you see lots of cold air induction systems made for cars; things only need to be warm during starting in low ambient temperatures. Similarly, the devices that induce turbulence to "help mix the fuel" are a joke; engineers spend thousands of hours getting rid of turbulence in the intake. The smoother the air flows, the more of it gets into the chamber, the more power you get--unless you have that fuel heater gadget installed.

Turbulence is perhaps the wrong word, there's any amount of turbulance after the butterfly or plate damper. But flow patterns to induce better mixing can help. Sarich here in Australia started with an orbital engine which was no good, but after he hired good help they produced a better carburetion/injector system which Honda now use. After Ralph Sarich was promoted sideways out of the workshop (with due regard for his founding confidence trick with the engine), he's since found that real estate actually works better still... for him. That's exactly the opposite of what you would want. The ideal situation would be to chill the air, chill the gas, and add a bit of humidity to the intoake air. vr wonder why the car seems to run so well on cool, damp days? Denser air, denser ful, and greater expansion in the combiustion process. >I saw this thing on ebay...it essentially wraps the fuel line around the >radiator hose, warming up the fuel before getting the the engine.

My V70 (1998 T5) has a returnless fuel rail to try to keep the fuel in the tank cooler. Some cars run the return fuel through a heat exchanger in the cold (low pressure) A/C line to prevent the fuel in the fuel tank from getting too warm. Cold fuel has 2 major benefits, it is less likely to boil (cavitate) at low pressure, and it evaporates more slowly. Cavitation can stop you dead in your tracks, and evaporating fuel is both pollution and wasted gas. SignatureMike F. Thornhill (near Toronto), Ont.

Engine manufacturers began engineering intake flow beginning with the Honda CVCC engine in the early 70s. Any change is going to be for the worse. Mike > Wow.

Perhaps if a small amount of whatever raises the octane in those additives-in-a-bottle, dissolves through the canister... but while mine can use basically any of the octanes, I can't measure any difference in performance or economy whatever I use. I have found here down under that optimax gives me more range and certainly better economy but at an extra 10c a litre it would want too.

Our shell garages have unleaded, premium (I think) unleaded and super, which has some sort of lead substitute.

I always hoped I wouldn't be as stupid when I got older... we have shell optimax on the east coast but its 10cents a litre more so only handy for long trips extending your range a little .Bp ultimate is fine but costs more too so does mobil 8000.why not use BP synthetic and bp ultimate then you will get longer life less friction and better fuel economy as well keep those tyres up . >> > > Where does optimax come from...

JG I read somewhere that for some reason you don't get Optimax in WA (or SA, NT and Tas). - think it was the Shell Website - Have a look. From memory, Premium Unleaded was the best they offered - 95 Octane. Here in Melb. they have just released Optimax plus which is 100 Octane. It contains 5% ethanol and of course is a bit more than regular 98 Optimax. Will try it and see if it makes any difference. John >>>Where does optimax come from...

Years ago I arrrived at the theory that Shell fuel formed carbon deposits in motors, specially those already prone. A couple of mechanics agreed and I have avoided it ever since. Times and motors have changed but I still have a distrust of shell fuel. Their oil is good though. > JG > [quoted text clipped - 25 lines] > > > JG We've been running our Ovlov on 10% EtOH blend here (Aus) and have gotten marked improvement on fuel consumption. Though, to put in perspective, the ethanol blend is a 98 octane fuel, so I would be surprised if it did SFA.

The Intake Twister increased fuel consumption by about 20 percent; the TornadoFuelSaver provided no significant change."

I think that we'd probably have more of a success building the atmospherica fat extracting machine that George did a skit on years sgo. This is the one that works on the premise "when people lose fat, where does it go? Into the atmosphere!" A little refining of the basic design and we convert everything to run on diesel with a little AFEM on the carburator, and we've solved the world's reliance on gasoline.
