It has been 5W30 for a long time. Initially, when I used to visit the ASC for the service, I was given a choice of either Mineral grade (15W40) that costs around 300 per litre or synthetic grade (5W40) that costs around 1000 per litre.

Now the majority of them stick to 5W30 even for the 1st generation Creta though it has been 2 years since I have visited the ASC.

Can you share the bill (after blanking the personal details)?

Yes. That's the one.

But 5W-30 A5 is not the correct specification of oil as per Hyundai Creta 2020 owners manual.

It should have been:

10W-30/40 or 5W-30/40 or 0W-30/20 SAE and
ACEA C5 or C3 or C2 (for DPF)

A5 is not in the recommended list of non DPF cars as well I think.

Here is the bill:




Although just speculation, if they are not using the correct spec of oil, would that not be a violation of Hyundai recommended service procedure?
Will this be an issue in the long run

I really really hope that they updated their oil with BS6.

Hmm. I’m not sure if any ACEA C5 oil is available in India. Maybe hserus can shed light on the long term effect on using the 5W30 ACEA A5 oil in the Diesel engine fitted with a DPF and if any oil of this spec is available here. AFAIK shell doesn’t have an engine oil specifically for diesels in India. Someone correct me if I’m wrong. The shell A5 is a oil that can be used for both petrol and light duty Diesel engines (Since we have DPF I’ve no idea of using this oil in the Creta BS6).

Please check out the information from the discussions starting from the below post.

Hyundai is ok with either of ACEA C5 or C3 or C2. Need not be specifically C5. Not sure how A5 spec will fit in here, especially with Creta 2020 having DPF.

Someone in Creta fb group had shared a photo of Shell Helix HX8 0W-20 C5 with 'recommended by Hyundai' label. States MRP as 1775, not sure if its fully-synthetic/semi/mineral oil. But I have not been able to find the same online, Shell India website does not even list Creta 1.5D engine and also has no recommendations for Seltos.

Below is screenshot of the same.



After paying 4500 for synthetic oil, I would be disappointed if they passed on a non-recommended engine oil grade.

This oil is not fully synthetic. It is made with synthetic techonology and that means semi synthetic.

AH is a grade of shell that is made only for OEMs and is not sold on the open market to my knowledge.

0w20 is a synthetic spec not mineral, probably a group 3 (cheaper) synthetic.

You want a nice costly and high quality c5 then this is the only one on the market.

Worry not about the synthetic bit.

There is no fixed formula for Synthetic or Semi synthetic etc , engine oils have to meet specifications - All of them that they claim as per API or JASO or whatever, how they reach there is proprietary. They may have various amounts of Synthetic (which is also dinosaur oil) and Mineral as per design.

If the oil provided by Hyundai meets specifications , that's good enough, even if it's the cheapest one in their menu card for your vehicle. Make sure to watch the oil level periodically especially for newer vehicles with thin oils OW20 etc , I'm sure the OEMs have done due diligence but these oils are new in our road conditions.

Engines are going back to timing chain from belt, a casualty of oil related problems is this chain - while in general the chain is better than the belt.

Semi synthetic aka synblend, mineral and synthetic mixed. Full synthetic group 3 is what most oem oils and other cheaper oils on the market are.

Easier to refer to group 1,2,3, 4

I’ve a question -

I plan to change the oil and oil filter in my Creta BS6 diesel automatic every 5k kilometres or 6 months whichever comes first. I intend to put in mineral oil only at the ASS. My idea is that the engine will be getting fresh oil often which is beneficial for the engine. Currently my usage is 90% highways and I’m a sedate driver - no hard acceleration, drive at around 90-95 kmph on highways. Is my decision correct? Economically this is slightly cheaper than putting synthetic every 10k. My only reasoning is feeding the engine fresh oil often. Mineral oil every 10k is a strict no no for me no matter what the manual says about changing it every 10k unless severe driving conditions.

Use what oil is specified for your car rather than change it according to whims and fancies. The company mandated spec has been tested over hundreds of thousands of km, so please use it. Change a bit more frequently if you feel a change is warranted.

I am actually ok with any good oil as long as it meets Hyundai's recommendation -
10W-30/40 or 5W-30/40 or 0W-30/20 SAE and
ACEA C2/C3/C5 (since Creta comes with DPF)

Any thoughts on the long term impact of using A5 grade oil instead of recommended C2/C3/C5 on 1.5 Diesel engine with DPF? I guess a lot of BS6 cars will be running now on the same spec oil they used in mine and I have a feeling (not sure) its A5 grade.

Not worried on whether they used synthetic oil or not, but worried on the exact spec/grade of oil they might have used.

I’m not talking about using a different spec of oil according to my whims and fancies. I’m talking about using the spec recommended by Hyundai and getting the oil changed from Hyundai ASS. I’m ONLY taking of the drain interval. Instead of going for the 10k drain interval and using a synthetic oil, I asked if it’s ok for a 5k drain interval using mineral oil. Anyway thanks for your suggestion.

Any specific reason that you feel that the OE oil which is filled by the ASC would not last 10,000 kms for which you are thinking to shift to mineral-based oil and change the oil every 5,000 kms?

Would the mineral oil put in by the ASC last for 10k? I feel most of us fall under the severe driving conditions with our roads and traffic and dust and the mineral oil, it won’t last the full 10k (I’m not sure so looking for some explanation from someone if it’ll last). I can go for the synthetic every 10k but I’ve experienced roughness (gruffness?) from my previous car (elite i20 diesel) after about 8k kilometres post oil change (this was pre-pandemic when I was driving 65 kms every day in peak Bangalore traffic). That’s why I was thinking of going for the mineral oil every 5k. Economically it is the same as going for synthetic every year. So why not? Is what I’m thinking. I was watching a video of an interview of a couple of lube specialists from Valvoline and they said this is good for the engine life (5k drain interval - mineral oil). So I’m trying to understand if there are any cons with changing the oil every 5k and putting mineral. Had read somewhere - Engine oils are cheaper, engines are not

Hyundai uses only one grade oil for all their newer diesel engines, this same grade is available in the optional synthetic form at around 2 times the price as their normal option. As per other BHPians have reported earlier the shell helix ultra comes in a big barrel , same as the HX series.
