Effuel is advertised to lower gas consumption by 15-35%

[gramps]

My question is? Is this for real? It plugs into the OBD2 port, and”
“Effuel is a small, compact, affordable, and easy-to-use plug-in unit that optimizes and lowers your vehicle's fuel consumption.” https://consumertrendsnews.com/big-oil-wants-this-fuel-saving-device-banned-for-good/?uid=92&oid=162&affid=129&source_id=9599&sub1=&sub2=24c13tlhqqe196&sub3=&sub4=382810156&sub5=

scam scam scam remember the carburetors in the 70's that were supposed to do the same thing. I didn't bite then and will not now.

Put it with the 100 mpg carburetor. The manufacturer has already put the best map in the computer for mileage and emissions. They have spent millions to meet the CAFE regs another 40 bucks isn't going to help. All this thing can do is lean out the engine which will set off the knock sensors and retard the timing making the engine less efficient. Lean isn't good if the temps are high either. If you want to save gas drive like grandma.

My neighbor swears that magnets clamped to the fuel line increases his fuel mileage. He even bought a second set to put on. :D

Thanks! My thoughts too, but I wanted opinions of people that know engines better than me! So why is AMAC advertising for these people!!! Grrr!

All it is doing is readjusting the MAP sensors readings. I wouldn't waste the time to order one much less use it. This thing is probably like inserting a resistor in the intake temp sensor line to make it sense that it is colder than it actually is.

Reminds me of the things sold sixty years ago that were a litlle plate that you inserted between your two-barrel carb and the manifold, having a couple of little fan-like "propellers" in the bore holes that spun while the engine was running, "atomizing your fuel for increased horsepower and better mileage". :wink: :lol:

Yeah, some motorcycle riders believe dumping lead fishing weights in their fuel tanks lets them save money by not having to buy premium grade gasoline.

A tin foil hat is equally effective.....

I remember at work we solve MPG gas saver pills. Supposedly it dissolved in your gas tank into millions of microscopic ball bearings that coated the cylinder walls, lessened friction and increased mileage. It looked like a lead pill. They sold a ton of them.
Later on on of our customers put one in a can of gas. It just layed there. Never dissolved.

Magnets again! I first heard of their magical power in the 70's. The hucksters even had large petrochemical companies convinced or their benefit. In the end we found they were great for holding papers down and storing paperclips.

There are many gimmics sold for just about every imaginal device.

This ^, no really, this ^ is the answer.

Even if you buy into the oil company - auto industry conspiracy. Think abut this. They all have the knowledge. Then in this very competitive field they would eek out just a tad of that knowledge to get .26 MPG more than their competitor. The the competitor would retaliate with meeting their .26 MPG and raise them .26 MPG of their own. (kind of a poker game) until it got so out of hand the cat was totally out of the bag.

Now, before someone says my 1980 something got xx MPG and my 2021 only gets XY. Your 198x didn't have all of the required safety items your 2021 has. Which means your 198x only weighed 2800 lbs. Now a small SUV weighs 4500 lbs. You got safer, added weight and lost MPG to cover the weight. I was floored one day when I realized my 1973 ocean liner Pontiac Grandville (deluxe Bonneville) weighed almost the same as a 2018 Lincoln MKX.

I drive a four thousand pound, full time four wheel drive vehicle (Subaru Outback)
that will consistently deliver thirty miles per gallon, in town. On the highway, it
delivers thirty-five to thirty-six MPG.

I can alter my mileage by five MPG (lower) simply by stomping on the gas pedal
as I start from the stop light or by driving as fast as I can (weave in an out, passing
as many cars as possible). - - - By eliminating those processes described in this
paragraph, most people will receive the claimed mileage increase at no cost.
(presumes you are not already driving that way)

I remember back when the first "shortage" happened in '71, '72 and the auto
manufacturers said there was NO WAY for them to increase gas mileage beyond
25mpg. - - - Humm, how many cars are now ABOVE that? IMO, the manufacturers
have been doing their best to increase mileage without killing the engines while
doing that. - - - Mess with the electronics and what will you get? None of us know.

I'll stick with my marginal 30mpg as delivered by a stock engine/vehicle. :wink:

To me, this is something like the red-neck "hold my beer, and watch this!"

Hi,

Short answer on AMAC: because they're paid to advertise!

Hi,

I once heard about this guy named Newton, who was good at reducing and simplifying explanations. He'd put Pat's description into three letters:

F=MA

I understand if you wanted to argue with him and try prove him wrong, you'd better bring your lunch!

If you tape it to the underside of the throttle pedal they work just fine.

Hi,

Sounds like something I read from automotive columnist Peter Bohr, some years back in the AAA magazine. He described the best way to get good mileage was to pretend there's an egg under the gas pedal. He said too many people treat it like an on-off switch.

Many years ago two of us took a trip, about 600 miles one way, towing a small U-haul style utility trailer. Empty going out, it was filled with a hot tub coming back, so there was a bit of sail to deal with. It was not my vehicle, but we split the driving, switching off at fuel stops. In either direction "my" tanks were consistently right about 10% better than the vehicle's owner got. The owner drove like both the gas and brake pedals were simple on-off switches. ;)

My old 1977 Chevy K20 4x4 pickup is sitting in the "no longer used" vehicle line and unless I took them off to use for something else, it still has the magnets on the fuel line. Whether the magnets worked or not, I paid more attention to gas pedal use and therefore got better gas mileage.
The effect of throttle abuse shows up now and then. Oddly enough, my Chevy 1500 extended cab 4x4 pickup doesn't necessarily follow the rules. It is more affected by road type and traffic flow. Cruise set on 65-68 (about 2000 rpm) and AC running on a 4 lane with moderate hills and lots of boring same speed driving is where it gets best MPG. I can't soft foot it with the window down and beat that MPG. That said, it doesn't take much resistance to change those numbers. A 10-15 mph headwind will cut the MPG by 2-3. We got 18-19 mpg from north MO to Dalhart Tx and then hit a headwind all the way to Albuquerque that cut us down to 16 mpg.
