Does anyone know if these "fuel additives" help increase gas inefficiency.
Additives such as "cleaners" "boosters" or plain and simple additives that claim to help gas efficiency.

they give you a bit of boost of performance of the tank you put it in, then your gas mileage goes down for the next two fill ups due to it.

The vast majority of fuel additives are a waste. Use a Top Tier fuel and you won't have any problems.

I use >>factory recommended<< fuel additives as preventive maintanence. Since the additives I use have been proven to keep the fuel system/intake valves cleaner, they do have the potential to "save fuel" in the long run. Also, as an auto repair shop employee I've seen numerous cases of fuel quality issues in my area. One $3 bottle of fuel additive used once every 6-8 weeks is enough to keep those problems away from me.

What about additives to correct for the damage which ethanol does to engines?

OK, I'll jump back in for this thought:

Back in the 70s I was driving a mid-60s Emeryville. When it was 20 or below, I always put a quart of alcohol in each tank to prevent gas line freeze.

Since this thread is focused on diesels, I'll bow out of this thread. I don't own a diesel, and wouldn't buy a pair of "Diesel" jeans even if I could afford them!

Traffic cop:"Considering there's no mpg advantage, what's the point?"

Not true. Diesels older than 07' will notice an increase. Heres a link were they tested 3 additives.

I use 4 ounces of Diesel Kleen with every fill up. It helps keep the injectors clean and gives me a little piece of mind.

TrafficCop - The diesel additive isn't necessary at every fill up to keep the injectors clean but with the Ultra Low Sulfur Diesel the additive does add lubricity to the fuel. The sulfur in diesel was the lubricating agent, with less sulfur there is less lube and with fuel pumps like I have on my 2012 diesel you want as much lubrication as possible. Older injection pumps could handle just about anything but the new ones can't (even a minute amount of gasoline mixed with diesel can kill the new pumps)

I rarely use additives. The gasoline I've been getting has been good, but I got a tank of bad gas years ago, and used additives to help until I had used that tank up.

disel8888, do you think you need an injector cleaner EVERY fill-up? Considering there's no mpg advantage, what's the point? I can't imagine that diesel fuel carries significantly more contaminants than gasoline.

I use redline fuel additive on every fill up. It has kept my injectors working great, but the MPG is pretty much the same. There might be a small improvement, but nothing overly impressive that I have to announce on tv.....

Well, I can still take it back. The $2.50 coupon I used would be my profit, as I'd probably get the full retail price back as refund. Anybody have anything good to say about this stuff?

Driving a vehicle on a daily basis highway speeds has never required me to need any additives,simply by running each vehicle on a reg. basis the fuel doesn't have a chance to get stagnet. I have always considered a Van type vehicle as not being efficient because of frontal aerodynamic mass,tire size,usually V/6 powerplants,extra weight due to window area sq in. of glass/seating,height,body cabin insulation,rear roof design for bulky loads don't help,heavy side door construction,etc.

Your occupational driving habits may hamper your personal driving,maybe not,concerning fuel consumption,a hurry attitude affects the right foot a lot driving.

With cooler weather,notice what the engine temps are doing on a warm-up,depends on the age of vehicle,but vans are harder on thermostats,rather the engine room is more cramped for good ventilation,can run hot,shortening the life of the thermostat,some get sluggish before real problems set in. Fall weather shows up a lot of problems often on vehicles.

I've used ST.. products before,for different reasons,depends if knowing what symptoms exhist beforehand....Vans often have larger heater capacity by volume ,often with the blower control on high,the heater acts somewhat like a second radiator,keeping the engine from warming at slower speeds delaying warming to normal,sometimes mileage suffers.

I've owned three vehicles that had large deluxe heaters,I tried a lot of things to save winter fuel and stay warm,one was a window van,driving at speeds of 25 mph,Cold Winter,that V/8 engine wouldn't warm to normal if blower was set above med. Highway Yes!engines working load was greater..

Here's one refedrence:

Myth: Additives to gasolines improve your car’s fuel efficiency.

Facts: “We have tested many different types of gas additives, and we have never found any that did anything to improve fuel efficiency,” says Steve Mazor, manager of the Automobile Club of Southern California’s automotive research center. Likewise, of more than 100 different fuel additives tested by the U.S. Environmental Protection Agency, none was found to improve a car’s gas mileage.

Okay, I just bought a 4-pack of STP injector cleaner at a warehouse store. Cost me $7.50 With tax, that comes to $2.00 a bottle.

Should I use it? or am I sucker and should I return it? Still have the receipt....

I drive a 2009 Sienna XLE, about 50K miles. Gets 14.7 crappy mpg. Thoughts, guys?

Going back to my post of Sooo thin texture; My trials/errors over time always had results,some good some not so. Comparing an additive with ones sences is not always the best way of judging a product.

Example; Most have used silicone spray,its thin,sprays good in most temps. After use one can tell whether or not a benefit takes place where a dry lubricant is needed.Unless you know the results will be better,or can see that product works,still maybe don't,can't understand how a spray film stays dry,non dirty,stays put,lasts,lubes,etc. simply by looking at it.

Many products demonstrated are that way,some maybe gimicks,some ligit for proper use,work well...temperary cure...My rule is if it's too good to be,it an't going to be dirt cheap. Biogradable uh huh!.....

If the product seems like a small miracle for you ,use the entire container up then,later might be in a % of wasted stuck...!^&*%)@~%~*^#

I occasionally use SeaFoam in fuel.No real MPG change but start and idle is better. Makes me feel good.

Many years ago a friction reducing very thin additive to gas and oil I tried at seperate times each one. Both raised the idle speed enough that I reduced it at the carb setting twice,It was discontinued for some reason.

This was used on a V8 STD.tranny hopped engine,after an oil change I never added again,but the results were fine,I had the feeling continued use might harm the engine sooner/later only because that stuff was sooo.. thin in texture...

Fuel tank sensor is the only additive recently used when my dash reading indicater started acting strange,the cleaner corrected the problem so far.

I used to purchase one through Amway. It really saved fuel.We had a suburban and an RV wit horrible mpg. The Suburban had 12 mg and the RV had 7 mpg. We would get about a 20% increase in mpg. We always track our mpg on these veicles and the joke with RV was it got 7 mpg full, empty, goin uphill into the wind or downhill with a tail wind. We towed an auto trailer with a car and the contents of a 3 bedroom apartment.... 7 mpg. So we were impressed with this fuel on fuel additive. We researched the company. They had nverhad any clais against them for any engine problems. My husband passed way and I sold those vehicles.

I don't expect them to all be the same, but that was our experince with that additive. I think the company went bankrupt and I have never tried any others.

they might do some good, but probably cost more than the savings you will see.
