Anyone using "Fuel Saver" Gadgets for your Car?

[inlinesix]

If you want to have a consistent fuel efficiency it's better to invest in a TPMS and a portable tire pump. Make sure the tire pressure is of the factory recommended pressure. Only pump up the tires when they are cold.

 

For fuel addictives, octane booster works only when your engine is turbocharged or have a high compression ratio. If your engine compression ratio is around 10:1, imo dont waste your money. As for fuel injector cleaner it only recovers your lost engine power due to carbon deposits. It doesn't boost engine performance. I'm sceptical about the 2 in 1 octane booster and fuel injector cleaner. Imo it can only be either one, not both.

 

 

Misconception: Many ppl think octane is a magic sauce, the higher the better. No. The octane "stabilizes" the air and fuel mixture when it's being compressed to a tenth of its original volume (eg. compression ratio 10:1). When petrol is compressed too high it will self burn or self ignite. When the spark plug fires its spark and the air fuel mixture is already spent this is called pre-ignition or engine knock. Your engine loses power. What the higher octane does is to "stabilize" the air and fuel mixture when it's being compressed(by the piston in the chamber), able to hold until the spark plug fires its spark.

 

So if using 95 octane your engine is able to perform optimally there's no need to use 98octane or higher. It's just a waste of money.

 

Factory recommended pressure is matched against load index used.

 

Tyre pressure needs to be adjusted as and when load index of replacement tyre changes.

 

For example, my Mini recommended 38psi with load index of 84.

 

When i change to tyre with load index of 88, i reduce the pressure to 35psi.

 

Rather than octane booster, i used RON100.  Shiok to the max.

Not entirely true Octane no effect on NA cars. Higher octane fuel allows the ignition timing to be advanced, i.e. Earlier ignition without knocking (akin to higher compression). This is associated with more HP and better efficiency. To a certain extent of course.

 

In Singapore, 98 fuel are taxed much more, so not worth the better consumption. I just stick to 95 and Rev more!

 

I tried RON100 on MYVI.

 

Every upshift is at 4k RPM.

The fuel-saving "gadget" that works and can be added relatively easy, is a lighter rim.

Wheel covers help a little too but are ugly.

Front bumper scoop may help or may not.

Front lip spoiler may help if there are no belly pan covers.

 

Using a lighter rim.

To save fuel put solar film on the glass.

 

The car less hot use less aircon saves fuel.

 

Insulate the cold aircon pipe in the engine.

 

On a hot day when you switch on the aircon you get hot air for a few minutes.

 

Insulate the cold pipe and you get cold air immediately.

 

Less aircon less fuel.

 

 

 

Also reduce any unnecessary weight in the car.

 

A slimmer MIL means less fuel used.

A clean car also saves fuel.

 

Dirt on a car adds air resistance.

 

So clean and wax your car.

 

 

Swimmers and cyclists shave their legs

 

as smooth skin is more aerodynamic.

i left my broquet and magnets in my previous car when i sold it ... intentionally.

 

You actually bought into the snake oil in the first place?

you'd be surprised at how i threw my money away when i got my first car.

underarm wax too? how about......white tiger

A nagging mil also consume more fuel as sil will want to send her home faster so will step harder on accelerator

Less hair less heat....off ac compressor also saves fuel..心静自然凉

My fren used to have a black car, a classic beetle.

Interior all black.

He says the aircon cools it down very fast.

 

I think the black body absorbs heat, it also absorbs cold very efficiently.

If it's those aftermarket type of aircon (the type that is hung below the dashboard) sure very cold one...I had it installed in my mini clubman last time...damn cold

The best fuel saving gadget is an egg underneath the accelerator pedal..hahaha.

 

Cheap and effective.

Electric cars will put all these BS into redundancy. With improvements and implementation of the airless tires, the term "fuel saver" is even more useless in the coming future.

So I'm useless

[Jamesc]

Electric cars use more gas.

 

Our electricity comes from gas fired power stations.

 

 

Hybrids better they don't use gas they use petrol.

[IanWui]

be gentle on the accelerator...

And adding performance air filters like Hurricane and K&N may damage your car in the long run as your car has been programmed to control the air intake with traditional paper air filters.
