Do Hyundai have a recommended oil for these engines?

Which brand do you use if you change it yourself? I'll be changing oil and filter myself between the dealer service.

I've used the info from the i30n Bible on the forum. I'm looking at the Shell Helix Ultra ECT C2 / C3
OW-30 fully synthetic.

I hope this is ok with forum rules?

Cheers Russ...
 
That is the oil that Hyundai uk recommended when asked.
 
Thanks for the info, that is a good price:eek:, I'll have a look as I normally use Opie and get a good deal.
Will be collecting the wifes little 1L i30 estate 2018 next Sat and was hoping they used the same oil, but it comes up with 5W-30-C2. wishful thinking.

Again cheers for the info
 
You won’t find it cheaper than from smith and Allan at Darlington.
Yes you will if not local. Those prices are ex VAT.

5l = £32.40 + VAT + £8.34 delivery = £38.88 + £8.34 = £47.22.

Opie's delivery is much cheaper. £39.95 + £4.99 =£44.94.

05100-00171 - 1L bottle of Mega Turbo Syn 0W-30 (API SN, ACEA C2)
05100-00471 - 4L bottle of Mega Turbo Syn 0W-30 (API SN, ACEA C2)

These are the stock engine oil for the 2.0 T-GDI engine. It is very cheap in Korea (£18 for 4L bottle) but may not be that cheap in Europe. Also, it may harder to get those in Europe. I've seen Turbo Syn (05100-00141/05100-00441, which is stock engine oil for the 1.6 T-GDI engine) in Europe but never seen those yet.

Russians are pretty enthusiastic about engine oil, and they think the oil is pretty good. Following is the google translation of a random Russian post.
https://www.oil-club.ru/forum/topic...syn-0w-30-api-sn-acea-c2-05100-00171-svezhee/

Oil is declared as: API SN; ACEA C2; OEM KIA 05100-00171.

1) The oil fully complies with the SAE standard and can be called 0W-30. Viscosity at 100 ° C and CCS at -35 ° C are part of the standard requirements.

2) First of all, viscosity at 40C = 43.38 immediately catches the eye - “this does not happen ?!” After all, this is the viscosity of most 0W-20. This means that despite the fact that it is "thirty", it will be economical as 0W-20, namely, when you start the morning and warm up to operating temperature. Secondly, it is a kind of record oil among 0W-30 - it fully deserves the title "Miss Fuel Economy" in the top of the ideal oils of the Oil Club

3) Viscosity at 100 ° C = 10.69 - and here, the oil behaves like a "thirty" - has the desired viscosity.

4) Thanks to such special viscosity characteristics, see what its viscosity index is = 248 CARL! The oil works in the widest range of temperatures, it behaves as a low-viscosity 0W-20 when it is not heated, and at the same time at the working temperature, it behaves like 0W-30.

5) Alkaline number = 8.3 - despite the fact that this is the ACEA C2 standard, limiting the ash, where you can’t jump above the head and you will no longer add alkaline. So, in spite of this, the base number of 8.3 is quite high for the middle pit.

6) Acid number = 2.0 - tall, there is a chance that the oil will work faster than ordinary oils, on simpler packages, but I think - without crime.

7) Sulfate ash level = 0.87 - and the ACEA C2 standard clearly defines - no more than 0.8. Therefore, there is an excess of ash. Although such small excesses, in a good mind and sound memory, hardly anyone will find fault, because here the laboratory can inflate and the manufacturer to overdo it with the percentage of additive package. These are little things ...

8) Flash point = 238С - are we just talking about low viscosity "almost 0W-20"?

I still do not know from what bases this oil is made, but it is extremely thermostable at high temperatures!

9) NOACK - evaporation of masses (waste) = 10 - class! Not many 5W-30 can boast such a PLA, and here low-viscosity 0W-30 and such a result!

Excellent behavior of oil at high temperatures and low consumption for waste.

10) The pour point -46C is the norm.

11) The viscosity of simulating cold scrolling with a starter at -35С = 6050 mPas is located at the upper limit of SAE. Enters the standard. Just a little bit more and it will be 5W-30. In general, this value ensures a safe start up to -35C, below it is clear not a record holder. The manufacturer specifically selected the recipe, the maximum base oil, the maximum thermal stability, and not to the detriment of low-temperature properties - which are usually less in demand.

12) Sulfur content = 0.331 - it is higher than the usual mid-ash table, because here the “fat” additive package. It is clear that base oils are pure sulfur, it is more of additives.

13) Judging by the level of additive elements, the development of Infineum + a separate friction modifier package based on organic molybdenum is used. Third-party he (Vanderbilt Molyvan) or his own, is a subject for discussion. (I can be mistaken if something corrected over time).

14) A very high content of molybdenum - it just adds a fuel saving function. It also has anti-wear function, while reducing oil viscosity, heavy loads, and even regular lapping of parts from the conveyor.

15) ZDDP anti - wear additives - phosphorus and zinc. Calcium-based detergent additives. Boron is an ashless dispersant.

16) In addition to all this, by oxidation = 31, one can say that the oil contains esters. Esters give the oil polar properties, reduce wear, reduce friction. The Fourier transform infrared spectrum also indicates that the oil contains esters.

Conclusion: Advanced auto industry oil, unlike any oil. Sharpened for record-breaking fuel efficiency. Due to its low viscosity on cold, molybdenum, esters - it will save fuel. At the same time due to ZDDP , molybdenum, esters protects the engine from wear. The oil has very good high-temperature characteristics (low NOACK and high flash) - even though it is of low viscosity, it is a rare feature for low viscosity oils. Low temperature characteristics are normal - they satisfy the viscosity class 0W-30. This oil can be recommended to owners of Korean, Japanese cars, where low viscosity oils are recommended. It is safe for direct injection, particulate filters and modern catalysts. Thanks to him, you get a record fuel economy and engine efficiency. Definitely it can be said that it is worth the money.
 
I have noticed after checking the oil level that the oil on the dip stick smelled like fuel. As this is a direct injection car, it is normal to have some fuel contamination in the fuel but i didn't think I would notice the smell that much.

Has anyone noticed the same thing?

The dealer technician told me it was normal as long at the oil level does not rise I should not worry.
I just hit 30000km 3 weeks ago.

I have VN with only 200 miles and I can smell gasoline on my dip stick as well. The oil level is still normal but I will be watching it more closely. This is my first direct injected car so I’m not sure what is “normal”.
 
Fuel dilution of engine oil is primarily due to blow-by. Blow-by is primarily due to poor piston ring sealing. Poor piston ring sealing is primarily due to a weak engine break-in. A weak engine break-in is primarily due to following the recommended protocol in the owner’s manual.

After 200 miles ??? Why is poor running-in prevalent with GDI engines?

Yeh fuel dilution is bad and is due to what is stated here. But fuel contamination is common, and more prominent in direct injected cars. Due to the high pressure of the fuel being injected directly in the cylinder wall some unburned fuel pass through the piston rings during cold starts, and hard acceleration. If the oil level rises above your full mark on the dip stick, then you have fuel dilution which is BAD.

I m going to keep checking my oil level, and so far so good beside the smell.

If enough fuel is getting into the oil that causes the level to actually rise, you have much, much bigger issues (like a leaking injector). Cold start behavior or not, the increased fuel pressure is not going to increase BMEP enough to cause a significant increase in fuel dilution. A bit more, perhaps, but you’re overstating the effect.

Turbocharging with higher intra-cylinder pressures has a far, far greater effect on increased fuel dilution when blow-by is excessive or even just moderate.

Change your oil more often and get your oil analyzed to see how much fuel dilution is occurring, since re-ringing the engine is not practical. There are treatments that can help a bit but once significant blow-by exists, it rarely goes away or lessens over time; usually gets worse.

Given the very low mileage one owner indicates maybe they are spending too much time idling the car to "warm it up" allowing fuel to wash down the cylinder walls and find its way into the oil pan. The first 5-10 minutes of driving I have noticed the fuel economy is very poor when compared to when the engine is up to normal operating temps. The ECU is most likely reacting to colder conditions and increasing the fuel to the cylinders under these conditions. This used to happen regularly back when dinosaurs ruled the earth and we used manual choke valves to richen the air / fuel ratio for cold starts. Users would "forget" to push the choke knob back in after the engine had warmed a bit and resulted in diluted oil or at least oil that had a petrol (gasoline) smell. :rolleyes:
As for the owner with 30k kms on the clock. That is 3 years of average motoring. Maybe you should start a thread to see who has the highest mileage so far. You may win. :D i30n taxi perhaps.
 
Just checked the oil on my Fastback N (1200km now, had it for 6 days :p) and i think it also smells a bit like gasoline. Problem is I'll have to drive 600km+ back to my dealer in germany so that'll be fun, I hope nothing breaks in the meantime.

EDIT: Oil level seems perfectly normal. Also don't let the car idle too long before driving away, max 1 min or so.
 
I just checked my oil and this time it smells more normal. I guess the first time I checked it I overreacted. The oil level hasn't changed from what I can tell.

I tend to let my car warm up for 5 minutes or so while I get ready and comfortable. I will try and turn my car on later instead.

I'm new to taking care of cars. I have driven a beater for years and only did the bare minimum maintenance to keep it running. My VN is my baby and I want to take good care of her so I have a lot of learning to do.
 
It’s not a GDI thing, it’s an inadequate engine break-in thing.
My query was aimed at the OP's statement "As this is a direct injection car, it is normal to have some fuel contamination in the oil", I thought you were answering that rather than making a general observation.

@Kage79 surely the compression by the piston prior to sparking far exceeds the increased pressure of the directly injected fuel compared to normal induction? Even though the fuel is at very high pressure it's effect on the volume in the cylinder must be low? Happy to be educated here.

Oh, ok, didn’t know that query was for the OP since it wasn’t quoted. Read what I posted in #8, it pretty much answers these questions already, somewhat indirectly.
