All about diesel engine oils

jav · 13th August 2009, 15:43

Hi guys whats your opinion on adding oil additive with engine oil, i tried oil additive when i changed my oil and my engine sounds way more silent and i can feel some more power, does it really work or is it just the oil change thats causing the difference.

Lots of mixed opinion. Is flush recommended for diesel engine or not?

I have a new Ford Ikon TDCi bought on 14th Dec' 08. Done 5000kms. Guru's, do you recommend engine flush or not. Do the Ford dealers do the flush?

if the additives are that good, how come the oil manufacturers didnt think of adding them in the first place

?

get a better oil instead

@ funkydude - Ford dealers will run after you to do the flush, since its a high margin value added service for them !

Not when it has done just 5000 kms. Wait till it completes at least 20 k kms or more.

Yes they would be happy to carry out flushing on the first service itself

just in case he was switching oil brands. This is advice i got elsewhere in this forum, not sure where

Please do not attempt the above procedure. If you do you would risk engine going Kaput. DO NOT I repeat DO NOT start an engine without minimum quantity of oil in Sump. Typically minimum quantity of oil is 80-90 % of sump capacity.

Thanks Jaggu. It will be a week or 10 days before I cross 5k, will post my experience. Will have to check with my Service Advisor if I can get Delvac MX at the Service Center, or should I source it myself...

First of all the below part is wrong, one should drain immediate and then wait for 5 or more minutes for oil to completely drip out.

old oil completely.

Now these modern diesel engine have grown by leaps and bounds. The oil contamination doesnt happen so much like old designs. I have posted the picture of oil sample from my ddis engine after 100+ kms of running IIRC which will show how efficient these engines are.

Up side is that engine oil quantity required in modern designs have gone down, down side being you have to keep a watch on oil quality, for long hazzle free life for engine. This is where the flushing at regular interval (20k kms or so).

This is not be all and end all, still it will help a bit to remove gunk better, especially if the oil is changed at longer intervals.

Some additives help in better lubrication and to keep the oil properties intact for longer time.

Not at all required, you can try it by 20k kms as rightly pointed out earlier. Ensure you change oil at regular intervals of 5-7k if on mineral oils.

Good point but its like why most car manufacturers dont include free flow headers or a better air intake system etc.

to keep the costs down, not wanting to take liabaility for 3rd party chemicals, meeting the minimum requirements standards of modern engines etc, oil mfrs may not add these additives to oil

Some additives have actually knackered the Cat Con (bringing down the efficiency and thus throwing up the EML and sending the car into limp mode) in some cars, despite the label saying CAT-CON SAFE

Additives are tricky, works for some and harms some !

Fully Synthetic oil have high detergent properties hence typically you would not need to do a flush before switching to mineral. while switching from Mineral to Synthetic it is highly recommended to do a flush. Else you would have to change synthetic within 5000 km run.

Use flush for best results since its been 20k kms, though no major harm otherwise also if you are planning a change at 5-7k kms. More important how many kms you ran with Mobil 1?

As far as detergents go Mobil 1 is good, especially for petrol motors but not the BEST for a diesel motor.

srikant · 14th August 2009, 16:52

I ve been using Mobil 1 Fully synthetic 5W50 from 15k changing at regular intervals. Next oil change due at 50k. So planning to switch to Delvac MX as 5w50 is not the right grade for DDiS.

sameer_dg · 14th August 2009, 17:52

Car: Swift VDI
Which flush to buy and which engine OIL, run 32000 Kms. Till today only given to MUL service station hence do not know if they really did change oil or not. It would be great if you could let me know how to use the flush. Pls help.

Got this news from my Chevron sales rep. in Pune that Chevron is closing their operations in India by Oct'09

.
Now I need to scout for another alternative to Delo-400,maybe Delvac MX comes close.Any thoughts anyone ?
