Improving Diesel Engine Performance
-
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 ...
Snake Oil = Placebo Effect: A Cure in the Mind

CT, how does the Powermag works?

Bodirection, what do you suggest?

you talking about improving your i30?

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 rental

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

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.

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

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.

All fuel are formulated to suit the car, any additional stuff is not necessary, in fact it will only give higher combustion, and your piston is still worn will worn more, so in a short run, back to square one, worst, piston rings worn faster. -
1985~1987 When we are running the FH 88 Prototype in Live Firing Area, Fuel consumption is one of our main concern. We can continues bull the Lardon (FH 88 Prototype name) for 96 Hours Non-Stop beside change Tester and Top Up Diesel.
We try all ways out to whacked our Lardon to test every Fuck thing we can think of.
Including Magnetize Fuel, Result show a Good Magnetization fuel system can save up to 30% of fuel. But the BIG BIG Ah Sir Kia Si dun approved （Because this is DPM Lee Hsien Loong Project, Every 3~4 Months, he will come to company for Project Status Update）, So we only used that on our owned Toyota / Datsun etc.

1985, I work for ODE, machining FH88 barrel using the latest CNC and Oto Morola rapid howitz for navy. Tested first prototype FH88 (non army involve) at thailand, 1st shot, muzzle drop down. All close shop go sol cowboy and sol nana fire own gun better.
We manufactured 100 over FH88, wanted to sell to africa and south america...no buyers, all said
Have to deploy, have to pull the 155 howitzer, have to get men, have to open the hydraulic legs, have to put up camoflague, have to dig mountain to keep it...knn..africa blacks said.
buy this better, just press button only -
So end up all FH88 put in seletar for show and become white elephant, and we, get retrenched, my friend become chief security guard officer, I become chief casket supervisor, talk about FH88, phui! FHM girl better lah

look at the engine performance curve . it will tell the the most economical driving rpm
