How to keep good FC on auto cars
-
Hi All, I am a first time car owner and waiting for my car to come. Any pointers as to how to keep the FC good for auto cars? Thanks!
-
The cheapest and most effective way is not to slam your accelaration pedal, keep rpm low... say bout 2500rpm....
the other ways tat u can use to torture urself for the sake of fc is not to switch on aircon
but of course not making your a/c too cold also can save a bit of petrol -
use cooking oil hahaha.....jokin! anyway...not all auto cars a fuel consuming what...some still good. anyway...just to slam slam anyhow lah...keep the accelerator pedal steady and keep a good gradual speed when speeding up. aiyah...very hard to explain...showing is better
-
i dono if my method works.. but.. accelerate it like u do with a manual car...
some auto cars will change gear if u release the pedal and press again...
maybe it works.. -
hey, i agree with doing that too, as in, accelerates and release to help the shift in gear.
after driving my auto car for almost 2 years, i've realised the change in gear from:
1st to 2nd at 20kph,
2nd to 3rd at 60kph,
3rd to 4th at 80kph.
And i'll accelerate till around there and release and accelerate immediately to help the AT achieve a higher gear sooner.
heard from somewhere that it's always better to engage a higher gear for better FC. -
cool this really works? ya of cos higher gear means lower revsOriginally posted by rumie:hey, i agree with doing that too, as in, accelerates and release to help the shift in gear.

Some pointer to share:-
1) Plan yr journey in advance, check the map what r the shortest route to yr destination.
2) Avoid those route that r frequent by motorist,
3) Do not ramp the accelerator while approaching a corner.
4) Accelerate with constant speed.
5) Change yr engine oil frequently to reduce overwork/stress to the engine.
6) Check for tyres pressure as stated in the manual, so not to cause extra stress to the vehicle.
Happy driving....

Do not shift gear to 'N' at traffic lights junctions. 'N' consume more petrol than 'D' with brakes. (RPM is higher at 'N')
-
Care to explain what u said?
What RPM will it be at N or D stationary?
If u noticed, the RPM of a staionary vehicle, whether at D or N, is 800 to 1K rpm. Your rationale is not right at all dude. For automatic cars, changing frequently to N will spoil ur gearbox more than anything else. It does not affect FC BTW.
Proper tips would be,
1. Dont use aircon.
2. Travel @ 80 kmh
3. Do not speed off quickly at lights
4. Gradual acceleration
5. If your auto gears comes with tiptronic, changing gears at 2.5K rpm is good
6. common sense stuff as mentioned by auto forumers like plan ur routes etc.
7. For auto gears, turn OD on.

Point # 5 is a GOOD point! Tire pressure is very much neglected by many people! I check mine once every 2 weeks!
Bro, its REV and not RAMP.Originally posted by blueoasis: Some pointer to share:-

There is a difference in rpm between 'N' & 'D'. Your rpm goes up when u change gear from D to N (For proof, watch your tachometer closely). It will affect your FC.
Fuel supply is cut off when u release your accelerator at D. Fuel is pump to engine at all times to keep it idleing at N.
This is a proven fact.Originally posted by LCL:Care to explain what u said?

Who proved it? You did?Originally posted by ed2win2:There is a difference in rpm between 'N' & 'D'. Your rpm goes up when u change gear from D to N (For proof, watch your tachometer closely). It will affect your FC.

This is a proven fact.
If fuel supply is cut when the accelerator is released, won't that make your engine stall cos no fuel to burn.
1stepping on your brakes while at D when stationary actually consumes fuel as well. Read in Wheels that it actually increases the FC by 10%.
If we remove the wear and tear factor caused the constant shifting from D to N, the FC of shifting to N would actually be lower... -
For me i rev to 2500rpm to abt 2800 rpm than i let go of the pedal...the car will auto change gear..
Btw i hear from top gear...like say u are approaching a traffic light..and the light is red...u let go out your pedal...the car is actually running on no fuel...so if i'm on safe fuel mode..see red light far away...let go pedal and let the car slowly come to a stop.. -
Have you watch ur tachometer when u 'D' to 'N'? Many drivers misunderstood that shifting to N actually save fuel.Originally posted by kyne:Who proved it? You did?

Btw i hear from top gear...
Ya, the reason behind it is that engine is still slipping a little fuel to prevent itself from stalling when in N but if it is in gear, then the kinetic energy generated by the moving wheels provide energy, thus no fuel is used.
Also other tips from top gear include:
- Control your speed till you dont have to brake at all (on highway)
- Empty all unnecessary weight to make the car as light as possible (wonder why no one have mentioned on this tread)
- If there is a slope, accelerate before the slow
- Pumping fuel at night when it is cooler, as cooler fuel is denser, so you get more...
- Keep electrical appliances in the car OFF, not just the air-con
- Listen to the correct radio channel (they say listening to the wrong one will cause you to be more hard -footed

Tips for reducing fuel consumption
The way you drive and the condition of your car has an impact on the amount of petrol you use. Here are a few tips to help you save petrol and money.
10 TOP TIPS FOR FUEL EFFICIENT DRIVING
1. Minimise your vehicle use
Plan to do a number of errands in one trip rather than several trips and save both time and fuel. Try to avoid short vehicle trips by walking or cycling, this will save over a quarter of a kilogram of greenhouse gas emissions per kilometre of vehicle driving it replaces. Also avoid peak-hour traffic whenever possible.
2. Drive in high gear
The engine runs most efficiently between around 1,500 and 2,500 rpm (lower in diesels). To maintain these low revs you should change up through the gears as soon as practical and before the revs reach 2500 rpm.
Automatic transmissions will shift up more quickly and smoothly if you ease back slightly on the accelerator once the car gathers momentum.
3. Drive smoothly - avoid unnecessary acceleration
Drive at a good distance from the car in front so you can anticipate and travel with the flow of traffic. This avoids unnecessary acceleration and frequent repetitive braking that ends up wasting fuel. It's also far safer.
4. Minimise fuel wasted in idling
Minimise fuel wasted in idling by stopping the engine whenever your car is stopped or held up for an extended period of time. By having the engine switched off, even for a short period, you will save more fuel than is lost from the burst of fuel involved in restarting the engine. The net increased wear and tear from this practice is negligible.
5. Speed kills economy
High speeds result in high fuel consumption. At 110 km/h your car uses up to 25 per cent more fuel than it would cruising at 90 km/h.
6. Minimise aerodynamic drag
Additional parts on the exterior of a vehicle such as roof racks and spoilers, or having the window open, increases air resistance and fuel consumption, in some cases by over 20%.
7. Look after your vehicle's tyres
Inflate your vehicle's tyres to the highest pressure recommended by the manufacture and make sure your wheels are properly aligned. Looking after your tyres will not only reduce your fuel consumption it will also extend tyre life and improve handling.
8. Use air conditioning sparingly
Air conditioners can use about 10 per cent extra fuel when operating. However, at speeds of over 80 km/h, use of air conditioning is better for fuel consumption than an open window.
9. Travel light
The more a vehicle carries, the more fuel it uses; an extra 50 kg of weight can increase your fuel bill by 2 per cent.
10. Service your vehicle regularly
Keep your vehicle well tuned and reduce greenhouse gases by up to 5 per cent. -

sgcarmart.com copy and paste from somewhere else one, coz I got it from another url other than sgcarmart.comOriginally posted by Lancerlot:he cut n paste from sgcarmart.com want...go there n read urself -
Sorry my appologies
saw wrongly, but they got 12 ways hehe.Sorry bro -
No problem man, actually I pasted that from another thread which i pasted for another person asking about the car tyre pressure in relation with fuel economy.

Let me get things straight. Are we talking about moving vehicles or stationary vehicles?Originally posted by ed2win2:Have you watch ur tachometer when u 'D' to 'N'? Many drivers misunderstood that shifting to N actually save fuel.
If stationary, the reason why the tachometer is lower when in D is because of the resistance the engine meets when you apply your brake.
The gear is sort of half engaged because it has to start moving once you release the brake.
Applying brakes also require electricity which means more fuel is needed.
If moving, i have read about the no fuel thing as well... -
U din really answer my question bro. Whats the difference in RPM? Let me know the figures.Originally posted by ed2win2:There is a difference in rpm between 'N' & 'D'. Your rpm goes up when u change gear from D to N (For proof, watch your tachometer closely). It will affect your FC.

Brother, relax leh........U sure don't want to save some fuel to damage the gear box dio boh ? The change of auto gear box cost about $6000, translate into 48,000 km based on 12km/l consumption. Boh hua right....But, at traffic light, if don't shift to "N", u put yrself in danger b'cos if someone hit u from behind, yr car will move into the crossing traffic....sure liao one. So, depends on situation and how long u waited.Originally posted by LCL:U din really answer my question bro. Whats the difference in RPM? Let me know the figures. -
every AT cars have a g-spot. find tat n you'll be a happy man.
