Things that I've actually done that work:
(on an automatic obviously) fit a custom-made torque-converter with an ultra-low stall speed. Dramatically improves fuel consumption round town, although the torque converter manufacturer may resist making it for fear of it stalling as soon as it's put in gear. Ignore them;
(On a diesel) Having the fuel pump outlet turned back to the inlet via 'Y' piece. Reduces the flow of fuel through the fuel filter and enables an old ford mechanical pump to make the injectors to be self-priming as well (note: don't do then when the lift pump is in the tank, only do this when the lift pump is built in to the main pump);
(on an old carburettor engine with automatic choke) Disable the automatic choke and fit a manual choke;
(On a standard petrol engine of any size): Use an exhaust for the next engine size down. For example, use a 1400 exhaust on a 1600 Astra mk4. The fitting is compatible, but it has higher back-pressure. It reduces maximum power but economy improves (yes, I can explain why, even though it's counter-intuitive)
(On a diesel) Fit an ultra-low back-pressure exhaust system, to improve both economy and power.
On any car) fit a higher-compression-ratio head and a camshaft with less open time for both inlet and exhaust (note: This requires an exhaust system with much lower back pressure)
(on a carburettor petrol car) - disable the accelerator pump jet mechanism. It's a total waste of fuel
(on a carburettor petrol car or an injected car that does not have closed circuit air/fuel ratio adjustment) - fit an Ecotek valve in the inlet manifold, preferably just after the carb before the air splits to go in different cylinders. Makes it start easier, makes it feel fuel injected, makes it more economical, makes engine over-run more economical (reduces engine braking).

Things I have not done that I intend to try out:
Change a 16v engine to 8v by removing half of the lifters or cam lobes (whichever is appropriate for the engine)
Reduce maximum engine speed to half through engine management computer
Use half-strength valve springs on the remaining valves

if you have a engine that the crank dipps into the oil in the sump a dry sump setup makes a big difference a cheaper option is to not fill the oil to max under half but well above min and check it regularly

[josephdupont]

The problem with over inflation. Besides, losing contact area with a road is the fact that you beat up your suspension system and a little bit of overinflation isn't bad but a lot of it can actually destroy your suspension because you a lot of problems later on bull joints, whatever😊

Undertray, Separation Edging, Air-Curtain, Hood Ducting, Cooling Air Redirecting, All that I'm going to be doing to my car in 2025. Getting more air to the intake plenum helps, and using 1970's emission set-up for quick pre-heat of the engine also is a winner. Moving the Capacitor to a cool place (Like the cool air-intake or filter box) also helps. For city driving I set the tire pressure to what's recommended by the car manufacturer, but if I am going on the highway I'll put an extra 5 pounds in them. As for 'Additives' I only use ones that have lubricants in them (Lucas) for the top of the cylinders. Great for long road trips.

In the case of fuel additives, It's not just about how it affects your fuel economy and whether that averages out to any fuel cost savings. The big one is about preventive engine health care. Some additives can go a long way to prevent certain failures, and significantly decrease long-term component wear. If your goal is to keep an engine running for as many generations as possible, anything that has a meaningful effect on engine health translates into major cost savings down the road. A clean engine will last significantly longer! Keep a proper oil change schedule and use a sensible amount of cleaning and friction reduction fuel additives at sensible intervals. And if you park the car seasonally, strive to do an oil change just before, and use a fuel tank protective additive and fill up the tank and then pull out the battery and let it sit undisturbed until it's season arrives. These tips will definitely help your engine last longer!

Water mist injection works, especially along with calculated cooling system masking

[sameerajgaonkar]

Smaller mirrors, under treys, naca ducts, underbody flooring .. longer tails, air dams work

[tulloh]

Hi, would you fit a vortex generator to an estate car?
Cheers

[sameerajgaonkar]

If engine has water cooled oil cooler .. then masking the oil sump to retain the engine heat wirk ... Need a temp sensor in the sump .. n nit to criss the sump oil temp beyond 120 deg C

there are some morons in hare, who don't know anything about cars. i am telling you that this guy and his channel is brilliant, and such a gem 💎 for people to learn about the cars 🔥🤘

Extralube ZX1 added to oil in engine. A little in the fuel and applying some to the gearbox and greasing the wheel bearings did reduce friction in the car and provide better starting. When used with hyper-miling the economy really was boosted in an old Corsa. Adding tires with lower rolling resistance also helped.

Extralube ZX1 Grease on the wheel bearing really reduced the friction and allowed the wheel to spin freely when jacked up similar to those fidget spinners.

I have had lower improvements in a one-litre Micra but didn't do the wheel bearings or gearbox.I believe I got 1hp more.

My current DIG-S seems to have benefited from ZX1 treatment. Engine oil and fuel only. It seems to run freer and have a little more power which can be used either for speed or using lower revs to gain the same power output. A small improvement in MPG was observed according to the OBC.

BG44K, Techron Fuel Treatment, and Archoil 6900-P do seem to help keeping my Direct injection Engine cleaner.

ASTA 3000 was also a very good additive but I cannot seem to get that any more.

[josephdupont]

How about cutting a strip of another tire slightly larger than the one you're using? Deflate your tire and put the strip around it. So you have less contact, area with the road.

[sameerajgaonkar]

Hot air induction works .. especially on petrol + part thrittle .. reduces pumping losses abd thermal losses ..

[sameerajgaonkar]

Ac high pressure line cooling with copper heat sinks works .. so as ac low pressure insilating with quality insukation

[michaelpopp]

Tires make a big difference.

Try some different fuel stations as some vehicles mileage can vary 10% or more from station to station.

Obviously, slow down if you really want to get better fuel mileage.

I had a Cummins diesel, which would get slightly better mileage when I added 2 stroke oil to my fuel.

if you put 17 inch wheels 205/45r17 from 185/60r15 but the 15's being steel rims and the 17's being super lightweight alloy rims, would you save fuel or worsen the economy?

[PaulThomas-qovy]

Econo Kit steam injection, petrol or diesel... Has anyone tried a kit?

[gertverhoeven]

I was a believer in pricely fuel and oil additives...
Untill a 40years of experianced and highly skooled mecanic made me understand this:
By the time the car seems to benefit from them it is actualy too late.
What it means is that you are using the wrong fuel and/or oil.
Infact, adding additives to a car that runs on the perfect chemistry mix does more damage than good

1:20 into the video and still havent given me a single suggestion pls get to the point

[jurlecluse]

According to this video my petrol car is an exception to the rule that improved performance by an ECU remap would decrease fuel economy. But not to my surprise really since my Volvo has a 2.5 liter engine with a low pressure turbo. The new setup of the ECU did not aim at max increase of power but focused mainly on extra torque. Thus making it a bit quicker but most and for all accelerate with so much more ease and joy. The sound is temporarily improved as a result of a broken cat and removed central muffler 😬
