Looks like maybe there is a new 3 way cat used?

ACEA C3

ACEA C3 engine oils are suitable for diesel engines fitted with diesel particulate filters (DPFs). Very similar to C2 but without fuel-economy requirements. Frequently matches specifications for BMW and DaimlerChrysler diesel cars. ACEA C3 oils may be unsuitable for use in some engines.

ACEA C4

ACEA C4 spec oil is a top tier diesel engine oil specification for vehicles with diesel particulate filters (DPFs) and Three Way Catalysts (TWC). Oils that meet this specification offer increased life for DPF’s and TWC’s and provide fuel economy benefits.

 

Until recently, A4 was reserved for future use in certain direct injection engines.

Its just an improvement, or change upon previous specs that the manufacturer - in this case Hyundai - feel is best suited to their engine. Where you have to be careful is :

A) Hyundai, originally cited two specs, A3 and C3 for the same engine; the C3 low ash was brought in due to issues with exhaust valves, at the same time their literature, manual and other info was still stating A3 - so in the event of a warranty claim you'd be covered both ways. Albeit, the change to C3 low ash was introduced when these issues with the exhaust valves were highlighted.

However...

What your dealer uses is anyone's guess. During a long debate on the forum over oil, a few dealers were asked what they used. It ranged from A3 semi synth, to A3 fully synth and everything in-between, with only a few stating they used C3 low ash as recommended. Thus, if warranties were going to made void in the event of engine failure (including an analysis of the engines oil), then many dealer serviced cars would have not been covered.

The moral : Use whatever Hyundai recommend, in this case A4, and make sure your dealer is using it - even though you have to accept that is what they are using !

 

Good points Biscuit, but with a dealer serviced car if Hyundai refuse warranty on the basis of oil, the dealer could be deemed responsible and have to pay for the repair having not used the recommended oil.
My guess is that any other action would be embarrassing for both Hyundai and the dealership and the rejection of claim would **** the dealership in court

 

Apologies i stated that Hyundai were now recommending an ACEA A4 engine oil.
This was incorrect the Shell sticket under the bonnet states a ACEA A3 oil.

Sorry for any confusion.

Interesting. What year is the car ?

The only under bonnet stickers I've ever come across are for C3 low ash, which became the source of confusion the last time this was discussed.

 

Its a 2015 1.2 Premium. Only had it two weeks.

Yes my previous 1.2 2012 year had the s5icker saying acea c3.
I have double checked and this Shell sticker definately says acea a3.

Strangely though it recommends the acea c3 for a diesel engine.
Unless they fit a diesel engine in the i10 for some markets.

So they've gone back from C3 to A3.

C3 is indeed suitable for DPF Diesel engines (not exactly an i10 !), but its use came in when some i10s suffered problems with exhaust valves coking up, something low ash oil like C3 addresses. I can only imagine the later engines have been sorted and reverting back to A3 - which is more suited to the i10s engine - is the result.

 

I don't seem to have a sticker in the engine compartment of my Sept 64 1.2 SE, but in the Owner's Manual it says:
For Europe
API Service SM or above, ACEA A5 or above ??
I really need to buy some engine oil to top up but I'm a bit confused as just what to buy, can someone please advise?

 

Yes it is all very confusing. Just noticed in my handbook pack a leaflet from Shell. This recommends Shell Helix Ultra 5w40 or Shell Helix Ultra Professional AG 5w30.

However as you say the handbook states a ACEA A5 which clashes with the sticker under my bonnet.

I will contact Opie oils and get their take on it.

 

For some reason, at an earlier date, I've written in the back of my user guide:
"Castrol Magnatec 5W-30A1 Fully Synthetic"

I must have researched it just after buying the car but can't remember doing it!

Does the above oil sound reasonable?

Anyway,thanks Stuart, any further information would be appreciated.

 

My owner's manual (2014 I10 Premium with 1.0 engine) recommends ACEA A5 oil and 5W-30 viscosity range for "best fuel consumption in Europe". The sticker under the bonnet says Hyundai recommend Shell Helix Ultra ACEA A3.

Both of these oil specs are for fully synthetic oils and I don't think your engine will wear out any quicker if you use the A3 oil instead of A5. My opinion only - not a recommendation.

I will be checking with the local Hyundai dealer to see what they use.

 

Engine Oil

I recently bought myself a 2014 Hyundai i10 1.2 and this will be my first car so I told myself to really take good care of it. With that, I'd like to treat my i10 a good engine oil which it can use for our daily travel together.

What engine oil do you recommend most especially for hot places like here in the Middle East? I'm new to this so kindly take some time and tell me why this should be it.

Is it helpful too to add additives on petrol?

Thanks a lot.

 

I've read from Hyundai site that it recommends SAE 5 W 30 but I've read from another site that 'W' stands for winter w/c is not what I need because I'm here in the Middle East.

What brand would you best recommend?

 

... I'm here in the Middle East.

What brand would you best recommend?

How in the world should we know what brands are available in your area ? 'Middle East' is very vague anyway. I could say 'Europe' but it makes a difference if I live in Norway or Portugal ...

W initally stands for winter, that is correct but in no way it says 'you must have winter' to use it as long as the W is inside the weight spec of a multigrade oil. W initially was only an addition to any single grade oil with weight equal or below SAE20.

I'd just recommend to you:
read your owner's manual, there are recommendations for any operating condition, minimum required SAE or ACEA or JASO class.
read around the web, there's tons of sites (e.g. bitog, or google 'all about engine oil')

Is it helpful too to add additives on petrol?

Yes. For the purse of the seller.

 

The information is in your car handbook. You can also check with your Hyundai dealer.

 

the manual recommand 5W30 for fuel economy.
All 5W30 are fully synthetic and simply any brand will meet the minimum requirement (if it's 5W30 I mean).

I think that it was 15W40 oil when I bought the car.

 

Apologies for dredging up this thread again, but I too don't understand the conflicting information.

My own car was only built a few weeks ago judging from the stickers stuck on various parts under the bonnet. As others have stated, the sticker stuck on top of the fuse box next to the battery, clearly states Hyundai recommend Shell Helix Ultra ACEA A3. But included in the owners manual pack, and by the way, my owners manual was printed in March of this year, there is a card flyer which specifically recommends Shell Helix Ultra Professional AG 5W-30 and the specs of that oil don't as far as I can interpret, match entirely what is printed in the manual.

So seeing as the supplying dealer will not have touched the car from a service point of view, I'm pretty sure the oil in the car is as out of the factory and so I'll buy a litre of said Shell Helix Ultra Professional AG 5W-30 for top up purposes only if required. If I don't end up using any of it before the first service, I can always chuck it in my other car at the next oil change! Just got to find a good price on the litre of oil, but I am a member of Shell Driver's Club and I get vouchers every three months, so we'll see how much I get off oil at my local Shell garage then.

 

I've just topped mine up with mobil1 esp 5wx30 as I didn't have nothing else , but I will be purchasing the shell helix ultra 5wx30

 

Just been looking at the Shell Helix Ultra prices this morning at my very local Shell garage. A lump rose in my throat, £21.99 for 1 litre of 5w30 AG!!! :surprise:

Clearly this oil can be had for far cheaper elsewhere online and to give an example of how much a litre can be had for:

Shell Helix Ultra AG 5W-30 - mytyres.co.uk

 

In the US my manual recommends Quaker State oil. Still made by Shell. But they cannot require a certain brand. Any oil that meets the spec is OK.

 

Just thought I'd share further in regard to my last post. I ordered a litre of Shell Helix Ultra AG 5w30 as in the posted link. Very smooth transaction, received in just a couple of days. The stock photo they use on their website is a little dated. The litre bottle of oil I received is the very latest incarnation, only bottled in May this year and shows the Dexos 2 specs on the bottle. The label is mostly in German and I'm guessing the price it's sold for is indicative of the fact it is imported and the prices are a reflection of the state of the Euro, which clearly works in our favour here in the UK.

I only bought it for 'topping up' but clearly I'm hoping I won't need to use it in our new i10 before the first service. In any case, I can safely use it in my other car as it fully meets the specs of that particular vehicle too.

 

i10 engine oil

My 64 plate 1.2 se I10 is due it's first service and I always buy the oil. I have purchased castrol magnatec 5w30 c3. Can anybody tell me if this is okay for the oil change? Many thanks

 

If you are going to use Castrol oils,Edge 0W -30 is the correct grade.

 

I was under the assumption it should be 5w30

 

Castrol say 0W-30,Shell(Hyundais preferred oil) say Helix Professional 5W-30AG.

 

Well, I couldn't help myself. Once again, I've ordered some more Shell Helix Professional 5W-30AG from mytyres. This time, I bought the 5 litre pack, arrived this morning direct from Germany after just two working days from ordering. At £24.50, ridiculously cheap compared to other outlets. I still have the 1 litre pack I bought for less than a fiver at the time, a few months back.

Shell Helix Ultra Professional AG 5W-30 - mytyres.co.uk

I don't need it for our i10, although that is the recommended oil, our car hasn't burnt a drop since taking delivery. Nope, this time it's for my Saab 9-3!

 

The manual for my I10 Premium 1.0 states 5W-30, ACEA A5. Stick to the manufacturer's recommendation and you can't go wrong.

My local Hyundai dealer (Evans Halshaw Gateshead) has confirmed they use 5W-30 fully synthetic. Castrol Magnatec 5W-30 A1 Fully Synthetic specification seems to be a match (http://www.opieoils.co.uk/p-754-cas...strol-magnatec-5w-30-a1-fully-synthetic-car-engine-oil-recommended-by-ford.aspx).

 

The Shell Helix 5W30 AG is the recommended oil, well certainly is for our 1.2, even the card that came in the pack with the car states it is. Indeed, if you input the i10 details into Opie oils lube match, if you choose the Shell oil option, it also comes out with 5W30 AG, but again, that for 1.2 engine.

Opie brings up the same Shell 5W-30 AG for the 1.0 plus many other options. The last top-up oil I bought for my car (1.0 premium) was the Mobil Super 3000 X1 FE which I got from Halfords - my car used approx 1 litre in 4500 miles (1 year period).

I don't know why the sticker inside the engine compartment recommends an A3 oil and A5 in the manual. However, if you check through all of the Opie recommended oils for the I10 there are variations in the ACEA spec.

My car had its first service recently and I mentioned the oil consumption - they said it was well within spec for the 1.0.
