All diesel can work with conventional euro 2m. It does not mean if you use euro 2m it's a direct death to the engine. My group has a owner who shares the same engine as the new sorento and clocked over 300k with mix fuel both euro 5 and 2m. Engine is still strong pushing out close to 600nm and 230hp. So the myth for instant death is debunked.

Running euro 5 means you will provide a cleaner fuel to minimize clogs on high impedance piezo injectors. The engine for sorento, is same as Santa Fe and same as karnival shares the same design of injector where it is non serviceable. You can try to use those ultrasonic cleaners but most people would recommend a full set change which is costly. Again this can be mitigated by using bluechem injector cleaners. Hyundai is offering this product as base cleaner during each service interval.

For dpf, the carbon sludge is subjected to high heat to be burnt off as carbon powder. You don't need to drive on expressway to flush the clogged dpf. Just rev the car at a high rpm and hold for a few seconds. The high velocity will push the debris out.

Lastly EGR do no operate when the engine is on load. So if you're on idle or cruising and using a cleaner fuel, there is much lesser smog being inhaled back. Ultimately you can reflash to delete egr or use the crude way of blanking off the egr from the intake.

To ts, there is nothing to worry about Diesel engine.

When you're driving in jam there is enough heat there to burn. Driving on expressway normally on cruise speed is low rev. That is not enough velocity to formally flush out the debris.

Never tried other cleaner. Sticking to recommended ones. So far so good.

Incorrect. It's newer common rail direct injection recommends Euro 5 fuel as the engine operates at complex magnitude and controlling precise curling to ensure minimal smog. They can still run conventional euro 2.

Its just like smoking. You know it's bad. But the side effect differs to people. Preventive measures like running injector cleaners etc can help prolong the life span but does not ensure longetivvity.

You rarely see diesel cars overhaul due to long mileage because they don't run like normal petrol piston ring. The higher the pressure, the greater the seal.

No such nonsense. Just pump in euro 2. Nothing is going to fail. Don't be paranoid, even fifth gear also confirm that diesel engine can run on petrol. If you accidentally pour in gasoline, don't worry. Top up more diesel. You will feel your car run smoother but slight less power. After bleeding out all the gasoline, it will just run like normal.


I think everyone here has a misconception on modern diesel car. They are not as taufu as you think. You can run a full tank diesel on idle till it runs out of fuel under the hot sun, and still you won't risk on getting your engine gasket burn. Euro 2 is like smoking cigar, while euro 5 is like vape. I can say the most fragile part of the modern diesel engine is the injectors. Because they operated at high parameters and electronically controlled by fast pulse.

Service or cleaning injectors there are a few specialist whom have the machine. Some injectors can be rebuild however some arent. You have to be specific. My recommendation is to just replace new injectors if possible.

By density yes if you're stationary. But not during motion.
