Catalytic converter theft has reached EPIDEMIC proportions in the USA right now. Gangs drive through neighborhoods carrying jacks and power tools, and they are capable of surgically removing the "cats" from any car in less than 15 seconds. Here is a video of a gang removing the cats from a police officer's car in California. The precious metals platinum and palladium are removed and purified for sale due to their extreme rarity and high price as raw materials in the car manufacturing industry.

Sometimes the raised car falls on the thief and squashes them like a rat in a trap, resulting in death or severe injury, meaning that Ogun, the God of Iron is also at work in the USA.

Americans never fail to spot a business opportunity, so a new industry has been created marketing metal plates that bolt underneath cars to protect the cats from being stolen when the vehicles are parked anywhere.

14yrs of driving, currently own 3 cars, and somehow I am just coming across the word catalytic converter!!!

So I thought to myself, How is this even possible.......I had to run to Google..

And realized that it's because I have never had issues with my exhaust in any of my cars..

Nonexisting:
So what if the windows are up on top speed but the AC is not on, like during cold weather, will it take more fuel than when AC is on?

treatise:

Not at all. Wound up windows compensate for the fuel you'd have spent when the windows are down because of the drag (principles of aerodynamics)

Nonexisting:
So in essence, driving with AC on takes more fuel that when AC is not on no matter the circumstances only that windows down on top speed drags the car backwards making acceleration harder. So instead of leaving windows down on top speed, it's better to have AC on so one doesn't suffocate right?

adanny01:


There are 2 cases with a bad oxygen sensor.

With a failed O2 sensor , the ECU goes to open loop and an error code is set which will bring on the check engine light. This is easy to diagnose.

A slow response O2 sensor is more difficult to know because it may not set an error code or check engine light and the ECU can remain on closed loop but the sensor is aged and not making fuel trim adjustment as required. It could lead to fuel consumption. Only a live scan and experience will be able to diagnose this.

treatise:


This submission isn't true. Before my catalytic converter was stolen I was able to cover 479 kilometers with 50 litres of PMS but since the theft, that same quantity of fuel can't cover 192 kilometers.

What kind of car do you use

drlateef:




Yes indeed. You consume more fuel in urban built up areas like intra-city driving. The amount of fuel you consume is about twice the amount for the same distance on the highway travelling at high speed. For example, if consume 10 litres to cover 20 kilometres intra city, you will spend about 6 litres to cover same distance of 20 kilometres on highway travelling at higher speed.

mu2sa2:
You're talking about stop-go-stop city driving. I had in mind driving at a steady high speed like 100 km/hr and moderate speed like 60 km/hrs - certainly fuel consumption will be less at the lower speed on a highway.

GAZZUZZ:
In most modern vehicles, when there is an engine or transmission malfunction , it displays the check engine light, this switches the vehicle from standard operating design, to one that limits power output and protects the engine or transmission from further damage that could result in continued use in that state.

You would notice things like

check 4WD

Traction off

VSC OFF

And so on.

In certain circumstances the engine would be limited to revs below 3000 rotations per sec.

Irrespective of the presence or absence of a catalyst, an engine or transmission code will cause a vehicle to run less optimally which in turn would mean the vehicle consume more than it should.

Avoid errors on your vehicle at all costs.

Buharifan:
Car experts,

Please how true is this assertion?

osazsky:
u have been scamed.ur exhust get small leakage.3k for solve the issue.i dont have catalyst and my fuel consumption is ok...

Innobee99:
Indomie is the common street name not Akara

clinician2x:


Then it is a shame. You paid all that money and spent all that years for nothing. Basic comprehension skills u did not achieve. Just the basic.

HazzanTazzan:


I’m not surprised ... going by your track record on here, ure just loud mouthed and insult your generation at the slightest chance ... the internet is really a great tool for kids like you to display their lack of home training

Clonelord:
You need to find the street name of that catalytic converter else men no go know wetin you dey talk About.

rukyboy:


I currently experience very high fuel consumption in my car. Would you avice I change only the first oxygen sensor?

My car doesn't have a CAT

adanny01:


What type of car and year?

rukyboy:


Honda Accord DC. 2007

There’s a top speed at which fuel consumption is optimum even on highway. It’s around 70-80miles/hour. Below that it’s high and above that it’s higher consumption. A combination of factors are responsible for that. At lower speed, I have forgotten that phenomenon in Physics which makes the speed of movement of tyres to give a negative feedback for less consumption and maintaining the speed. But this happens at optimum speed I mentioned. At higher speed above 80miles, the effect of wind comes in to increase the consumption. Wind effect is less at that optimum speed. Other factors are engine size, the body size, shape, fuel efficiency of the car, and weight of the car, a full petrol tank contributes to the weight and causes a drag thereby causing more fuel consumption.

9icetoo:

It's actually 80km/hr or 50 miles per hour.

At 80mph, your mpg is taking a serious hit.
