Fuel Efficiency

[Watchman]

Hey!

There’s been a couple of posts asking members how efficient various vehicles are on fuel. And with the prices going up by Rs.8/= and with news in the air that it will go up again by another Rs.3/= soon, its getting even more important…

So what do you say we post the following details

Vehicle :

Transmission Type :

Engine Capacity :

Fuel :

Km per Ltr (city/long distance) :

You guys didn't get it. Actually he meant AC is Off.

I'm not sure about that J, but generally when you set to 30C doesn't the heater starts? (unless the inside temperature is higher inside). Otherwise could have mention A/C Off right?

Car: Nissan FB15

Year : 2000

Engine Capacity : 1.5L

Fuel : 92 octane petrol

Transmission : Auto

Fuel Economy

Colombo city : 8-9kmpl

Highway : 12-13kmpl (At 80kmph)

Outstation - Upcountry : 9-10kmpl

Outstation - Flat roads : 11-13kmpl

Tyre pressure : 35psi

Tyre air type : Normal

Driving strategy : Light acceleration, moderate speeds & Air conditioning at 30C .

As the others have already pointed out, your tyre pressure is way too high. It should be somewhere around 28 - 30. While you might be saving a few cents off fuel, you are wearing out the suspension of your car faster - that's a repair that will cost you far more than what you will be saving on fuel. Also, your tyres will wear out much faster. You might want to consider all that and inflate your tyres to the recommended pressure. It should be printed on and attached to the B pillar of your car - driver's side.

As for the AC, I don't think I have the right to decide what's the right temperature for you, but I believe 30C is way beyond the comfort zone of an average human being. Plus, you might want to try and wrap your head around this to determine if you are really saving money on AC:

If your AC is manual, and if you have your temperature dial set a bit towards the warm side from the "max cold" position, the AC is still working the exact same way to how it would work if you set the dial to "max cold". Most manual AC systems reduce the cold by activating the heater and mixing the hot and cold air so that the air reaches a "less cold" temperature. Again, this is on most manual AC systems and I believe it's the same case for you as well. If this is the case, your passengers (and you) are suffocating for no actual gain.

I guess he has a climate control AC system, (If the car is a Super Saloon) Otherwise he couldn't have known the set temperature. In that case the compressor should be disengaged most of the time.

I keep the air pressure at 32, is it ok. the reason I don't keep the air pressure at 28-30 is thinking that it will result in even less ground clearance.

Well i dont know what type of AC he has but there is a very common issue in the fb15/n16/y11 series cars with auto climate control (not the ac unit with the dials but the one with push button and green colour indicators on top). The temperature is not properly calibrated on these, on cars with this unit even if you set it to 30c it's still cold as hell. IE at 30 the heater doesn't enguage and 30 feels more like 24c. And 30 is the lowest you can go.

This might actually be the reason.

Really? That just might be it then!

Depends on the manufacturer specification for your car. What does the information card on the B pillar say? And are you running on the stock rim size and tyre size? I really doubt that 2 - 3PSI is going to give you significant ground clearance.

What you mention here is a classic symptom of blocking the heater core by our maka basses I guess.

Out of curiosity, how many wheels does your 'car' have? Does it have the following badge in addition to the Axio and hybrid synergy drive badges?
