Check the 2 & 3 in the post which reads 20W40 so that is the wrong grade.

2. HP Milcy Super 20W 40 - NVH very high
3. Castrol GTX 20W 40 + Bardhal - NVH very low compared to HP

0W40, 5W40 are preferred oil grades for diesels IIRC.

The recommended grade for TATA Aria is 15W40.
However any grade with xyW40 should work fine.

HP milcy is good for Tata's IDI engines but for some reason it does not go well with TATA's common rails.

For common rails Mobil Delvac has proved to be very good (from my experience).

Looks like he tried that earlier. That is not the right grade, wonder why he tried that, that too in an Aria.

Where did you find that info ? These are synth's. Not necessarily preferred, though the AS.S will "recommend"

Correction- The previous grades used were 15W40 and not 20W40.

4. Mobil Delvac1 - NVH Much lower than Castrol GTX in a cold start, once the engine heats up no noticeable difference.

Bought the Mobil Delvac1 5L can with MRP Rs. 5000/- @ Rs. 4000/- i.e. 20% discount.

What is Bardhal? If gtx & delvac 1 are comparable, then gtx is real VFM.

Bardahl here is referred as a oil additive like the 'System D' for diesel engines.

They are more into petroleum lubrication. Vast number of products they have. You can check their website.

would it be safe to run a petrol engine on Mobile delvac 5w-40? the oil description states that it is good for heavy duty diesel engines, but is also compliant for gasoline engines.

Is there a difference between mobile 1 and delvac?

After trying Shell HX7 diesel at 25K kms on the odo, have shifted back to MGDO (Maruti - Genuine Diesel oil from Shell) during my scheduled 30k service at Maruti Service Master Chennai. They don't allow oils from outside anymore and this was the only choice in mineral. For synthetic, they use Mobil1 use for both the K series & DDiS engined Swift/Dzire/Ertiga.

HX7 was revving beautifully but MGDO is a bit more smoother.

It is better to wait till warranty end after which you van buy your own oil + oil filter and change every 5K if you intend to use mineral. If you are going to use synthetic oil then it is going to be changed every 10K kms.

Initially when I had the Ritz, I used to change every 5K kms but now I stick to MGDO (Shell or Mobil whichever they stock) and change it every 10K kms.

Just wanted to add a performance review of Valvoline Premium Blue CH grade 15w-40 oil. My preferred oils for the Verna CRDI have always been Shell Helix HX-6 and Mobil Delvac MX. In the last service I couldn't find either, so my parts dealer convinced me to settle for Valvoline Premium Blue. The price was much cheaper than the other 2.

9000 kms and 6 months later, today I changed the oil to find it retaining at least some viscosity. The engine note hadn't turned rough either, though the last 2K kms there was reasonable smoking at high revs. Overall, much better than the Servo/MAK CH grade oils and a cheaper, almost-as-good alternative to MDMX and HX6.

At last, I found 1 litre bottle of Castrol GTX Diesel 15w40 oil for my Safari. This oil is rare to find in general oil shop and everyone keeps Castrol GTD oil. I just bought for refilling and in emergency purpose, if oil level goes down. I am planning for 5000 Kms long trip coming May. I stick to company recommended oil change schedule which is 15000 Kms or 1 year whichever is earlier.

This one litre bottle I purchased from Bhavani Automobiles near KR Puram bridge.

How does the engine feel at 80 kmph and 100 kmph respectively? NVH levels with NO A/C and with A/C. Do you find any difference?

In my case,the Engine sounds much more smoother at 80 and 100kmph as compared to when I used delvac super 1300 and delvac MX.Yes there is a sizeable difference in NVH levels after using delvac 1.Not looking at any other options now.The Delvac series sure is tailor made for the DDis engine.

A few days back when I was at a Maruti's spares godown, a pamphlet was lying regarding MGDO being the choice for Maruti's DDiS engines.

The oil mentioned was Mobil Super MGDO Fully Synthetic which is available in two grades 0W40 & 5W40. Comes in 3L and 5L pack but there was only the 5L pack on display. Forgot to ask the price though.

I am thinking to try them once the free services are over. Currently will be going for the third service for my Swift. Want to see what MGDO is filled-in this time.

Dear BHPians,

It has been 2.5k kms since the oil was changed from Castrol Synthetic to Mobil Delvac 1 and here is a quick summary

1. Smoothness very much there
2. Noise levels have come down
3. Low rpm response seems to have improved in every gear
4. And the most important part - Mileage - It used to be a challenge to get 15kmpl but now with AC I consistently cross 16kmpl on the last 3 refills.

Seems like the Diesel Engine specific synthetic brew is working like a charm.

Will post an update post 5k.

A big to the product

I wanted to replace the engine oil on my Punto.

I was looking at OWS 5W40. Is this a good oil? Any updates on performance?
