Improving Diesel Engine Performance

cold air is denser than hot air, which leads to a bigger volume after combustion.as long as our air con feels colder than usual, most probably we`re getting...

I think this is something Diesel Engine Drivers will be interested in.

Some doing 14 km per litre. Some doing 9 km per litre.

So,.. what is the secret.

Yes the engine age and condition plays a part,

but how can we as drivers do some simple things to make the engine go that extra mile,... errh, kilometer.

Please share, whether it's a special additive, or some home made trick or getting the mechanic to do something special.

Thanks..

I read somewhere that people pour some petrol into their Diesel tank.

Will this help to clean the system?

Will it damage the system?

I use to deal in car accessories...

Magnets do not work period ( Snake Oil)

Additivities are questionable ...

Some leave sediment build up in the Petrol tanks.

Use with caution ...

CT, how does the Powermag works?

StriveOn SG

Bodirection, what do you suggest?

or spend $600 plus to $800 to let specialist to tune the car?

everything comes with a price, is as good as spending extra on top of your diesel topup

so does it transform into saving? i mean A plus B and it still back to square one

some model powerful, but old technology, new model, save fuel but come with a higher

Got no i30 leh...

Got Magentis and Crownn.

everyone driving style is different, one must understand the type of model he is driving

and how it perform, light foot does not mean travelling at constant 90km per hour will

translate into fuel saving

other factors also play a part, how you move off stationary position, slow moving off

or fast pick up

over taking on the road, how often and how it is done, too many to factor to translate how

one can go for max mileage with lesser fuel

StriveOn SG

Last year, my Comfort Crown, very bad mileage, plus black smoke.

Less than half day service, Power super, good mileage, and no black smoke.

I think they tuned it.

Thanks.

Does Premier do tuning?

fark lah, magentis and crown are old model

nothing you can do, lucky get the best of the worst magentis you get 10km per liter

suay is 8km per liter

crown also the same but should do better than magentis

in fact all this two model, i only have one word, the magentis can scrap liao

crown still worth a little to try

Angwk7118 SG

want go get a crown lah, forget about magentis unless you want auto

Angwk7118 SG

tuning i refer to outside, but not for this 2 model

only you can do is keep complaining to your dro about jiak you

worst is they just ask you change to another crown

Why high consumption? simple

Because of aging, piston rings worn, liner bore worn result in fuel slip thru, on the other hand carbon built up at the piston head cover and liner can also result in reduction of space for combustion, resulted lack of power and therefore stepped more on the fuel pedal.

Of course, the best is to overhaul the engine, but that take time and expensive, overhauling the most is once in a life time for car, overhaul twice, something is very wrong, pte car half overhauling already cost nearly 5k, full about 10 to 12k, parts change not yet included, and if need to change piston rings, pistons and casket, it could amount to more than 15k, that is why, most car at 8 or 9 years, changed, some 5 years changed liao. Engine overhauling is like human going for heart operation, you dun go heart operation often.

So, those who want to buy 2nd hand car, please look the engine,

One method is use mineral oil and run the engine on the road for 500 to 1000km, then change it to normal oil, do not do engine flushing which is alway recommend, it will end up more fuel usage.

The engine is like a human heart, it take time to warm up, you cannot keep jogging it, like some at ap, stop off engine, then on again, it work more hard and in long run, worn out faster, if you flush it, it is like cleaning the drain with chemical, the drain cement also wash away, yes the drain become very smooth for water to flow, and imagine your fuel will flow like water...

Like a human heart, time to rest, it must rest, best is constant timming, 6 hrs rest per day in between shift.

And for reverse gear, give time for it to change before reverse, imagine you suddenly turn around, sure to fall, in long run, crankshaft worn faster or even crack, then god bless us all.

To check engine, on engine for a minute, keep looking at the cooling container, if bubble come out, engine leaking air liao...no good. This is call bubble test, if no overhaul, engine get heated up more easily. High rpm will be needed to run a hot engine, and that translate to more fuel use.

Understand that most of the additives out there do not work because the diesel we buy already have those additives added in.

But if there is a special one, that is different from the others,... maybe can give it a try.

bowah SG

All these please do not try, if anything goes wrong, companies found out, you are solely to blame for engine failure or electrical failure due to magnetic influence, those who drive new car, be it taxis or pte car, most are under warranty, if you put up these, all warranty become void due to self illegal modification.

Taxis is not ours, if taxis eat lot of fuel, report back to workshop, talk to your CSO or DRO< if still insist can drive at 8L/km, then aske them to go fly kite, thrown key or card and drive for others.
