Team-BHP - All about diesel engine oils

I wonder what is the reason for this big difference? Both are diesel common rail engines with a difference of 15 bhp (considering FGT 1.3) and just 100 CC difference. May be it is the size of turbocharger which is making the difference.

My 1.5 Verna also has the same capacity of 5.3 ltrs. Again a 100 cc difference in i20 and Verna but same engine oil appetite.

Totally confused with this disparity!

More to do with engine block design and oil pan capacity, modern designs are more efficient and are very environmentally conscious. So the designs would lean towards reducing consumption of fossil fuels including engine oil. Yes a very large turbo with dedicated oil cooler might need a bit more of oil, but i don't that is the case above.

That is some good saving for Swift/Vista and MJD fellas who use synthetic oil. Straightaway Rs. 1500 saved (Considering Delvac1 for 750/- per ltr) and some 500 bucks if using mineral oil.

As you said it is the engine block design and some other technical aspects which decides this theory. Only Hyundai can tell the reason behind.

Isn't the Verna a VGT? And Mortimer a bigger capacity engine + intercooler so tp keep both filed appropriately the design of the oil pan would be different from the 1.3 MJD/DDiS.

1298 cc is the MJD and around 1498cc could be the Verna so I am guessing the difference of the engine oil quantity. :)

Hi buddy,

We are considering liter (Displacement) to liter (Oil quantity) comparison (Hyundai crdi vs MJD/DDIS)
MJD/DDIS - 1.3 Engine - 3.1 Liter of oil
Hyundai CRDI - 1.4 & 1.5 Engine - 5.3 Liter of oil
That is some good 1.8 Liter difference for mere 100/200 CC variation:Shockked:

Apparently it is a major design difference between both the common rail engines.

Why should oil be present in the intercooler? Won't it obstruct the airflow?

Mmm - Interesting - @archat

Sharing my usage pattern

Usage of my Accent CRDi is quite similar to yours where in I complete just around 2k / month but I use Delvac 1 so that I can complete my service every 5 1/2 month. The Swift on the other hand though completes just around 1k in a month and complete 8k in 6 months which is the reason for using Delvac 1

I like Delvac 1 as it gives me 10k service interval and excellent protection. May be you could try Delvac 1 once and keep us posted.

For first time I want to use synthetic in my 40k Verna 1.6 CRDI Fluidic. Only available oil here is castrol edge. Surprised to see that the specification is API SN/CF & another API SM/CF. Car manual says to use API CH4. Has any one used castrol edge? How is it that so pricy oil has CF specification whereas for petrol engine it is Sm and SN.

Please advise whether to go for edge.

Thanks

My Swift ZDi is at 3500 kms (1 month 10 days old) and shall be getting it's first oil change after the 5K service as MASS is still adamant on 10K kms oil change and don't want to keep the oil for so long. I am thinking to fill in mineral oil.

Please help which oil and should I choose?!

@anurag - Had finally the opportunity to drive @80 in 5th gear and the rpm was hovering just around 1800 but to maintain a steady 100 kmph the engine's rpm was just around 2300 ~ 2400

VDi rides on 185/70-R14

Hope this helps

Cheers

Thank you Sateesh for the update. A few more questions from my side. :)

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?

Did you upsize the tyres? As VDi rides on 165/80 R14. What make ate the tyres btw?

The complete drive was with A/c ON so can't comment on it explicitly but I didn't "feel" any difference per say.

I didn't but I felt the stock tyre size was puny and went in for 185/70-R14 and trust me I haven't repented it at all.

I maintain 34 psi for the front tyres while 32 psi for the rear tyres and it has been brilliant

I am on MRF Z.LO

Cheers

Recently did an Engine-oil change in my Aria here's my experience so far:
1. Stock Oil (Castrol GTX Diesel)- Too early to comment
2. HP Milcy Super 20W 40 - NVH very high
3. Castrol GTX 20W 40 + Bardhal - NVH very low compared to HP
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.
