Does anyone know what happens if you use normal diesel for euro 5 diesel vehicle? If I am not mistaken few years back, BMW modified the engine slightly so that the cars can accept our low grade fuel. I am interested in the sorento hs, but cannot see how to use it in east coast Malaysia. Also do owners of Euro 5 diesel have anxiety when finding petrol stations to top up? Or there are abundance of euro 5 in your location.

Hi there

I have several modern diesel vehicles

There is no big deal if u pump euro 2m diesel for it , just that in the long run, it hurts the engine

Euro 5 stations are aplenty in my area , BHP Shell Petron Petronas all within few mins reach

The only times I need to pump euro 2m is when outstation to ulu place for business or vacay

Then no choice, but to pump low quality diesel

Most diesel models brought in through official distributor here have been tuned to adapt low quality diesel, therefore it is not a big issue if u can't find any euro 5 station.

Even my reconditioned UK spec diesel car has no problem refueling euro 2m

Not good for injectors , EGR get clogged fast , catalyzer also fast full and mine with DPF is death sentence , once a while is ok but long term will hancur engine

I normally use Euro5 in my Ranger but it's not always available. I don't notice any difference driving on Euro2 but I guess it's not good for the engine or environment.

If a car only takes Euro5, I wouldn't buy it. You can't be sure that you can get it in Malaysia and you don't want to run out of fuel in a diesel.

Thanks all for the feedback

Or worst come to worst, buy a few extra plastic tank and refilled it in KV before balik kampung and so on.

So at least don't need to worry can't find Euro 5m diesel.

If it comes to this, then using Euro5 is a chore. I don't mind finding a petrol station 10 mins away. The nearest is 52 mins one way. So does not make sense.

IF you want to drive a diesel car that preferable euro 5 and insist on using euro5 then I believe by that time you already accepted the fact that euro 5 is not widely available outside certain regions.

Then, such chores are expected and shall be tolerated without any issues haha.

Only mazda diesel here have strong preference to euro 5 and the SC will mention it to you. Other brands all made some adjustment to accept euro 2 without too much issue.

Since you are using sorento, it would do fine with euro 2. I ran santa fe same engine for euro 2 for initial 60k km, only after that then switched to euro 5.

But euro 5 will do well on all non commercial vehicles here nonetheless.

Because Mazda no modification at all , no retuning, no removal of diesel particulate filter , is identical to an Europe export car

That's why must use euro 5.

The only modification they did was just to remove the DPF filter. No difference otherwise from the engine for BMW.

Which resulted in their cars generating more wheel horsepower than advertised

Nopes, lesser due to the longitudinal engine layout. For example, on paper it is rated 184hp for the N47 diesel engine. On a zero load dynojet dyno, it pulls around 170-173ps only. For the B47 engine, on paper it is rated at 190hp and on the same dyno, it gets around 176ps-177ps.

Ah , apparently the quoted is on crank. 173 back calculated apparently is more than 184 on crank

Can't back calculate like that as well, note that this is on a zero load dynojet. On Dynodynamics, the figure is much lower.

So this article posted previouly does not happen then?

OK... if I remember correctly, the fuss BMW made back then was with regards to Malaysia's half-arsed hot-hot chicken shit B10 biodiesel fuel. BMW claimed B10 biodiesel will fuck up BMW diesel engines.

Not the regular diesel fuel.

In my limited knowledge, the key diff between older diesel engines and Euro 5 engines is the cat converter. Euro 5 car converters are required to remove more crap in order to comply with the stricter emission standard of Euro 5, so it helps to use cleaner diesels to begin with. Right?

Therefore... it follows reasoning that using the old shit diesel in a Euro 5 car will just foul up the Euro 5 cat converter sooner. That said, there are driving techniques that you can use to 'clear up' dirty cat converters (drive until engine up to temp, then WOT to 'clear the exhaust' or some shit like that).

And even then, everybody knows cat converters will all eventually die anyway regardless. Some people even remove them outright in their quest for more power.

Despite the lower fuel cost and higher performance of diesel-engined cars, owners of such vehicles are advised to enjoy these advantages only in Singapore and not across the Causeway because of the big difference in diesel fuel quality.

New diesel-engined passenger models sold in Singapore are Euro 5-compliant and the ultra-low sulphur diesel sold at the pumps here contains only 50 ppm (parts per million) of sulphur. This specification is compliant for use in Euro 5 diesel engines.

On the other hand, diesel fuel sold in Malaysia is Euro 2 compliant, with 500 ppm. Euro 4 standards with 50 ppm are expected to be implemented in 2015.

"It is not recommended for the new Kia Sorento Diesel to use Malaysian diesel as it is of a much lower grade," says Chin Kee Min, senior manager of authorised Kia distributor Cycle & Carriage Kia. "If lower grade diesel is used, it may cause engine clogging and misfiring issues, and perhaps other related problems as well."

A workshop manager who did not want to be named said that if the wrong diesel specification - such as one with high-sulphur content - is used "persistently", it could risk clogging the diesel particulate filter and may also cause engine damage.

"If there is a need to fill the tank, do not overfill but have enough to get across to Singapore and then refuel with better quality diesel in Singapore," he said.

He explained that using lower quality diesel may result in some "light smoke from the exhaust" as a result of the high sulphur content.

"It is also advisable to run the vehicle with the better quality diesel at expressway speeds for at least 20 minutes so the diesel particulate filter can regenerate itself. When in doubt, take the vehicle back to the dealer for a proper check," he added.

As for loading a jerry can with diesel from Singapore and carrying it with you for trips up north, the workshop manager does not recommend it.

He explains: "For safety reasons, this is not advisable."

Then again, the superb fuel efficiency of a diesel-engined car may not require most owners to fill up in Malaysia at all.

A Wearnes Automotive spokesman says that with a full tank of diesel, the Jaguar XF 2.2D will be able to travel "over 1,000 km".

"An owner is likely to be able to make a short trip to Kuala Lumpur and back with no difficulty," he said. "However, if absolutely necessary, customers are advised to top up only sufficient diesel to travel back to Singapore and not to fill up a full tank."

Catalytic converter kong is not really much of an issue, won't even show check engine light or whatever error message on car screen. The main concern is the diesel particulate filter and also most of our driving is low speed city crawl, euro 2 produces lots of this particulate. Unless we have mandatory exhaust test like developed countries, most don't even know the catalytic converter is already dead.

DPF clear the crap in it by "burning" it off inside the build in chamber, and the system uses diesel. This is called regeneration. The process utilises the exhaust heat to light off the diesel. If we don't have extended fast driving rpm above 1500 and lot's of traffic crawl, the exhaust temperature in the DPF chamber isn't high enough to burn off the crap in it. Some cars with more advanced ECU won't let you shut down the car and let the engine run till this regeneration process is completed.

But most don't have such advanced system control. If off engine while regeneration, the DPF will be soaked in "unburned" diesel and will back flow to your engine oil sump. And after sometime, the DPF don't need to be fully clogged, but there's a point of no return where unless someone did a very very long drive, the DPF just cannot fully regenerate. Anyway, after sometime also, the DPF will deteriorate anyway unless the car is purely long distance drive.

That's why, diesel cars with DPF usually have 2 indicator on their engine oil dip stick. One for regular oil change, the other upper limit is the max sump capacity inclusive of the "diesel backflow". After reaching the upper limit, like it or not, must change engine oil. Fuel dilution inside oil sump is very bad for lubrication and protection properties in the engine oil. A DPF set isn't cheap to replace...

So, to avoid all the hassle, almost all diesel engined vehicles in malaysia have no DPF installed.

Don't worry, got great news in the future, all direct injected petrol engines will need to install particulate filters and all motorists will suffer together, whether diesel or petrol
