Mixing Super Diesel And Auto Diesel?

[ModX]

Guys, I've been using super diesel for a KIA Sorento for a while and thought of swapping it with the auto diesel (Moment of truth: I really don't wanna pay that much on fuel and expect the key benefit of buying a diesel in return). Will there be any consequences of doing this, specially to the engine? Appreciate your response.

Anyone knows? Please

Yes the same CRDi engine is used by the hyundai santafe and the company advices not to use any thing other than super diesel.

This is due to the high compression bla bla bla CRDi has

so I think this should be applicable to jap direct injections too

Thanks for the info. Can I use an additive with the auto diesel instead of super diesel???

I dont think that will make any sense. IMO Its always better to use super (unless your running a lorry or bus) for the long term benefit of a cleaner and less worn out engine (specially if you have used it from inception). Anyway your still paying much less than petrol right ?

Coming from a background of european diesels, i cannot stress enough the importance of using super diesel over conventional auto diesel. Even using super diesel, i used to run a bottle of Forte diesel treatment once every 3 months. Forte is a recommended additive for CRDI engines. Eventhough CRDI's lack conventional mechanical diesel pumps, there are so many other commonents such as pressure sensors and high pressure injectors that are very sensitive for the fuel type used. It would definetly be penny wise pound foolish to try and save probably Rs. 1,000 every time you fill up a tank and putting your vehicle at the risk of potential repairs that can reach hundreds of thousands.

Everything comes at a cost. But paying an additional thousand rupees or so for a full tank is a miniscule compromise to benefit from the fantastic performance and efficiencies CRDI engines provide

When I was reading an article it said that the sulphur content is important because using Ultra Low Sulphur Diesel (ULSD) can deteriorate your engine cylinders and all. But some says using ULSD is good that it doesn't create any sulphur oxides in the cylinder. I'm really confused. Now exactly what fuel do I really need to use?

Hmm, Thanks for showing me light. It won't be worth enough to save Rs.1500 each time I fill the tank and spend all those saved money to a mechanic in future.

Don't worry about the googled articles mate,

This is sri lanka and u wouldn't find anything ultra low in Sulphur

Sri Lankan super diesel is only slightly low in sulphur

Been discussed about your exact same vehicle

I would recommend you to use super diesel, in the short run it will be costly but in the long run considering the repairs that might come it wouldn't make any difference.

And no unlike petrol in which you can use additive to boost octane levels you cant use additives and get the super diesel quality from auto diesel.The reason for this is that they use very different manufacturing processes and it cant be altered by a simple auxiliary fluid.There are additives for diesel but those are mainly intended for cleaning internal engine parts.

Thanks for information machan. I went through that thread. But, I gave a phone call to the agent and they did not recommend using Super Diesel. :S

Then what did they recommend ? o.O

[ModX]

They just said that the auto diesel would do! :S

[rangerover]

Of course they would say so. The Sinhalese proverb "Horage Amma-gen peina ahanawa wage" applies perfectly to this situation because;

Firstly the agents wouldn't want potential sales hurting because of the higher fuel cost at the pumps,

Secondly, who benefits from your high repair costs?

So it is up to the owner to do his or her own research and make a prudent decision. After all it is your vehicle and you should take the responsibility for it.

Nope you were given information by an idiot, read this

Even if the agents still say to use auto diesel i would still use super diesel if i were you.

Well, first of all thanks for the information you've given me machan. I have decided to continue with the super diesel. But based on your facts why Hyundai recommends their customers to use super diesel and Kia doesn't. It cannot be the fact that the Hyundai is so devout. They've their Santa fe's and Tuscons in the line for sale. Nevertheless, they don't stop at recommending you the super diesel but which brand to purchase as well (Cypetco).

This is because the santa fe user's manual recommends not to use fuel additives(additives are present in IOC xtra mile diesels) which will damage it's catalytic converter.

The sorrento is a santafe with a different body so IMO you should adhere to what hyundai lanka says rather than the morons at kia

Hyundai lanka are more consern about the vehicle and the customer than carplan

The best out of the available choices - super

Those agents really confused me big time. What-so-ever I'll stick to Super Diesel as you guys advised me. Thanks alot for your valuable informations Guys.

Supper diesel on normal diesel engine makes the engine running dry. Super diesel has less sulphur. Auto diesel has more  sulphur. Sulphur vapor in cylinder lubricate the components. Less sulphur means less lubrication.  This leads to engine fault. it is like running your two stroke engine without 2T. So, if you are runing auto diesel vehicle with super diesel, add some lubricant to the tank. but I cannot recommend what is it and how much :)

Using auto diesel in engines need super diesel also a problem. It doesn't expect this more sulphur vapora nd impurities. It sneak in to engine and let you change your engine oil more frequent. Also it blocks injectors and exhaust system with these impurities and worst fuel efficiency and finally engine fault.

So far, the common public opinion is, most of the common rail models still manage to fare with normal diesel, according to what I heard from various dealers, colleagues and kin, 

Ford Rangers, even the super rare late model everest, Ranger Raptors have no issues,

Common rail powered Defenders have had issues, esp 2.2L models, older models can even manage kerosene😁, no idea about Range Rovers though

Kias, Hyundais are having no issues, Mitsubishis with the 4d56 common rails, 4m41 common rails have no issue, 

Most of the Toyotas have no issues except for the 1KD, (occasionally 2KDs), issues mostly in the Vans and Hiluxes

and the 1GD which is the most notorious of them to have issues with normal diesel. As per Toyota it can get so bad it goes to limp mode in the auto models. 

The Isuzu Mu-X is also doing well with normal diesel as per a friend. 

Meanwhile BMWs have issues and injector failures in 20k+ miles on normal diesel. (Have a friend who needs new injectors for a 2017 X5)

Newer Mercs on the other hand are managing despite dealers scaring owners to do tuneups and engine cleanups!

Then again this is a very inaccurate feed as there have been instances of soggy fuel as well as heaps of water in fuel messing up the injectors of the above.
