Logically thinking, this can not be correct. A common rail motor should need a minimum of CH4 oil for the engine to remain in perfect health. CD/CE are obsolete, CF4 is in use but only for older, non common rail engines. I am not saying you are wrong, but probably this is from the manual which can be wrong or not updated for a long time. Other members, please correct if I am wrong.

I would again mention, those who want to use synthetic in their diesel engines, please stay away from Petrol specific synthetic oils as they do not offer synthetic like protection to a diesel engine. Instead of spending on them, please use good diesel specific mineral oil like Delvac MX and change earlier than 10k km's. If you want synthetic only, please invest in Delvac 1. In my opinion, considering the oils available in India, anything else is NOT worth it.

EDIT: Also, please don't go by SA's and service centre's recommendation of the petrol specific synthetics in a diesel engine. They sell it to you at MRP and make a good amount of money by doing so. The oil does not do you what you expect it to, in a diesel engine.

Quoting my own post as I missed to mention this earlier. If the oil is approved by your car OEM with a special approval number, then it's good to use that oil irrespective of it's API rating. E.g. If VAG has certified VW 507 approved oils for use in it's CR TDI engines, then it's good to use all oils with this certification in those engines. Similarly, Fiat has approved Selenia WR 5W40 for it's MJD engines while this oil is only API-CF. Ford also has certified oils for it's TDCi engines. For more details please see below post by a fellow member ph03n!x.

There are multiple oils by the name Shell Helix, both for Petrol and Diesel. So unless there are more details available on the specific make, they just may or may not be different oils that are used at Hyundai. I think it might be a good study to identify the oils used by various A.S.S. for the various cars. I saw that Carnation used the wrong specification oil for Alto and on questioning, I was told that they use the same semi synthetic oil for all Petrol Engines that they service :Frustrati.

Thanks

I would suggest Mobil delvac 1 if you are going for synthetic and Mobil Delvac MX if you are going for mineral... Please dont do the same mistake that I did my puttin Shell helix ultra in 10k km service of my swift vdi abs. Also dont go for mobil 1. Mobile delvac 1 or mobile delvac MX would work out good..

Hi Guys, I have a Verna CDRi that has clocked 35k and now due for service, please suggest a good engine oil. I was thinking about the total engine oil. Has anyone tried Total engine oil? I am not looking at the synthetic and would be using the mineral oil.

Please advice which is a good mineral based engine oil is good the verna CRDi and now that is run 35k, should I try the STP flush and injector cleaners as well?

Thanks.

Hi Sagarpadaki,

Which one are you using? I had tried the Shell Rimula and was not happy about the overall performance, found Servo much better than Shell Rimula.

I'm becoming more and more inclined to believe that non CRDI engines are better off with older engine oils, or at least the indica diesel engine. Folks here recommended delvac MX, delo 400 etc, all with progressively worse results. Finally my current TASC used some HP milcy, and the smoothness is back. This has been confirmed with other indica /indigo owners. Any non CRDI engined vehicle owners have any comment?
