Please specify engine, transmission, AWD/2wd

 

 

I usually hover at around 8l/100km or 30 mpg, then again I pretty much always electrically pre-heat my engine and don't drive a lot in the city, mainly 60-120kph roads.

2001 3.0 manual awd

 

 

Yeah that's never a good recipe for saving fuel

 

Same here.
We need to install a switch to disconnect 3 fuel injectors and drive on 3 cylinders, that is what Honda Pilot 2wd does.

 

I've got the 2003 2.5l AWD with a manual tranny and put mostly highway miles on the car...the drive to the office has been shortened but is still roughly 30 miles each way. The odometer is just shy of 160K miles.

I don't have the lightest of feet and tend to see somewhere around 24MPG. The managed lane is a posted 60MPH but on at least one direction each day, it is not uncommon to run closer to 80-85MPH. On the drives to Austin from the Houston area (about 150 miles), I am usually running 75-80MPH with few stops.

 

2.2 litre diesel 2010 xtype front wheel drive only manual gearbox. 60,000 on the clock.

Round town cold start about 38/40 mpg Motorway at legal 70mph I get 64.mpg

Fuel cost here is £5.50 gallon.

 

How much is gasoline there? Is diesel fuel cheaper? Diesel fuel is more expensive in USA, that is why diesel cars are not popular.

 

Oh really? Tell that to all the diesel pick up truck owners and not the most fuel efficient

 

We don't use "gasoline" But Petrol is just a tad cheaper. Both prices fluctuate around each other.

 

You'll get very low MPG but then you'll also buy little fuel so the cost will be minimal and thus hard to worry about.

 

I very nearly bought an older Jaguar V8 in immaculate condition. As clean underneath as on top. Problem was the fuel consumption. Guys wife said you could watch the fuel gauge needle drop just getting it out of the garage.
Saw him later and he had sold it for £300. A truly magnificent low mileage motor. Fuel costs here really are dreadful.

 

But of course no ic engine likes to never get a good run so service costs are high.

We in the Uk have the economical Diesel engine cars which to aid air pollution have a DPF "Diesel Particulate Filter" fitted. This to clean up the emissions somewhat. Problem is the filters are prone to clogging up which can be an expensive exercise. To keep the filter clear one needs to go for a nice long fast drive. Which of course adds to pollution. CRAZY INNIT?

 

I suppose not buying a car like that may be the answer.

 

That is NOT the reason why diesel is not popular...too many still associate it with stench and the mess while fueling, with some being old enough to remember the crap GM pulled when they tried to convert a gas engine to diesel (failed miserably). There is a reason diesel owners in the United States tend to keep a pair of leather gloves specifically for fueling...

Given the increased fuel mileage with diesel, the price point right now makes it about a break-even proposition. I recall the spreadsheets on one of the truck forum to determine how long one would need to keep the vehicle in order to reach a break-even point for the added cost of the PowerStroke. Of course, back then, we could get diesel for under 70 cents a gallon while regular unleaded was over a dollar. Now the spread has gone the other way, with diesel being ~60 cents more per gallon near the house.

 

Worst carbureted car can have not more than %25 lower MPG than modern fuel injected car.
Perfect gas/air ratio is 14.7
Worst is probably 12.3. If ratio goes lower, spark plugs will not work. This is simplified theory.
Carburetors have different fuel systems (idle, mid range, power, pump). If one of the systems is really messed up, other systems can clean plugs.
Old Jaguars (1976 XJS) had fuel injection w/o o2 sensors, so MPG could be like carburetor cars have.

 

On this side of the pond, the type of petrol(ium) we put in our non-diesel tanks is called "gasoline" (92 octane, as the sticker recommends), which has hovered around $3.50 per gallon for years here in New York.

Over the course of ten years in my 3.0L AWD - mostly suburban, a little highway, I have never managed more than 16-18mpg on average.

 

3.0L petrol, automatic, 167k miles.
For a long time it was about 24.5mpg. Probably 80/20 highway vs in-town driving. I am not a "spirited" driver generally - I've got 100k miles on my rear brakes and they are just wearing out now.

Lately I have been getting about 21.5 mpg. Going to have the spark plugs replaced - never done before and I suspect it will help. Also, may replace fuel filter myself.
