Person to contact - Vinod kumar - 9745008277

just a correction. the road to take is the road opposite kaloor bus stand (SRM road)

Just changed to Shell helix diesel hx6 from servo on my Rocket. Though engine smoothness is way better, engine knocking is felt which wasn't there before. The oil level is right on the max level. Any one experienced this ?

[satish_tns]

Vdrive. I found that I mistakenly changed to shell helix ultra 5W40 in my swift vdi abs. I should have gone for shell helix diesel ultra or shell helix diesel extra.

After changing to shell helix ultra 5W40 fully synthetic on the 3rd free service, after doing 800 and odd km, engine oil pressure light started to remain on. Had the engine oil pressure sensor changed under warranty as that was found to be defective. Not sure why that happened after doing 800 km from changing the oil. I dint want to analyse more on that and I am happy with it now after the engine oil pressure sensor changed. So my first experience with shell was a bad experience though the oil performance was good for a week from the oil change and is back to normal after the oil pressure sensor was changed without changing the oil that i filled in. Waiting for odo to read 15k km as will be switching to mobile delvac 1. .

If your car is mostly doing in-city rounds, please have 10k as the oil refill cycle if you choose synth - else keep it at 5k (for mineral). And IMHO any oild will feel ok in the first 1000 KM or so. If your oil is of a wrong API spec than what your car needs, its recommended you switch ASAP to the right oil.

@ Satish - Always check if your oil meets the recommended standard. Else, don't use it even if it's a synthetic. Helix diesel ultra is API CF whereas your owner's manual most likely recommends a CH-4 oil or above.

@satish - The MJD needs oil that is atleast CI4 rated. The 5W50 is definitely not CI4. The new generation oils have better detergents to cater to the EGR , WGT etc to keep the oil working without significant degradation of lubrication properties

The oil sensor going bad may or may not be related but with all the exhaust gases compressed along with clean air the possibility of the former is quite high

Please change the oil asap to one that is as per specs in the manaul

Cheers

A related query and I am very confused about this. All fully synthetic oils except Delvac 1 are API CF for diesel engine. So all of them are not good for a CRDI engine? I wonder then how Fiat has approved Selenia WR 5W40 for use in it's Diesel MJD engines. Selenia is also API CF. Infact, I have never seen any A.S.S fill Delvac 1. All of them fill API CF rated synthetics (Mobil1, Castrol EDGE, Shell Ultra etc.) if the customer wants to use synthetic in diesel engine. Can all of them be wrong or are we missing anything?

I think we are ignoring the fact that many CF rated oils are approved by the OEM's despite of their CF rating. I think Mobil 1, Castrol EDGE and Shell Helix Ultra like Selenia are approved by FIAT for use in MJD engine.

If it's still wrong to use these oils in diesel engines then the only choices diesel CRDI onwers have is to use diesel specific minerals (CH4 or above) or Delvac 1. Any thoughts?

+1

Exactly my thought too.Either the A*S*S dont have any awareness about this rating or the manufacturers dont track or control the oil used in the A*S*S!Even in hyundai service center they use the same helix oil for both petrol and diesel.I dont know if they atleast put different mineral oil for petrol /diesel atleast

Here is a quick reckoner on various certifications available for engine oils. Oils manufacturers design their oil to meet / exceed the requirements of these certifications, and vehicle manufacturers specify engine oil requirements considering the fuel standard, quality, and lubrication requirements required from the oil (among various other factors) to keep the engine ticking away.

Standards defined by Associations

API Service Categories - American Petroleum Institute represents about 400 petroleum corporations. he association’s chief functions on behalf of the industry include advocacy and negotiation with governmental, legal, and regulatory agencies; research into economic, toxicological, and environmental effects; establishment and certification of industry standards; and education outreach. API both funds and conducts research related to many aspects of the petroleum industry.

Apart from other activities, API also defines industry standards that comply with legislative and regulatory requirements, and safeguard health, ensure safety, and protect the environment. Each publication is overseen by a committee of leading industry professionals. API's publications are developed by member company engineers and other professionals.

The current standards defined by API is available here

ACEA - Association des Constructeurs Européens d’Automobiles, denotes the agreement between the European Manufacturers and the European Commission to limit the amount of carbon dioxide emitted by passenger cars sold in Europe.

The 2010 ACEA Oil Sequence Guide is available here - it is a detailed report, with Page 5 & 6 explaining what we need to know.


SAE - Society of Automobile Engineers has established a numerical code system for grading motor oils according to their viscosity characteristics. SAE viscosity gradings include the following, from low to high viscosity: 0, 5, 10, 15, 20, 25, 30, 40, 50 or 60. The numbers 0, 5, 10, 15 and 25 are suffixed with the letter W, designating their "winter" (not "weight") or cold-start viscosity, at lower temperature. The number 20 comes with or without a W, depending on whether it is being used to denote a cold or hot viscosity grade.

Note that the SAE has a separate viscosity rating system for gear, axle, and manual transmission oils, which should not be confused with engine oil viscosity. The higher numbers of a gear oil (eg 75W-140) do not mean that it has higher viscosity than an engine oil.

ILSAC - International Lubricants Standardization and Approval Committee, is formed in 1992 by AAMA (American Automobile Manufacturers Association, representatives of DaimlerChrysler Corporation, Ford Motor Company and General Motors Corporation) and JAMA (Japan Automobile Manufacturers Association) to define the need, parameters, licensing and administration of lubricant specifications. In general, ILSAC works with API in creating the newest gasoline oil specification, with ILSAC adding an extra requirement of fuel economy testing to their specification.

ILSAC, API, SAE and ASTM (American Society for Testing and Materials) form the Engine Oil Licensing and Certification System (EOLCS).

Standards Defined by Manufacturers

By the early 1990s, many of the European original equipment manufacturer (OEM) car manufacturers felt that the direction of the American API oil standards was not compatible with the needs of a motor oil to be used in their motors. As a result many leading European motor manufacturers created and developed their own "OEM" oil standards.

Back to @amit1234singla's question - The owner's manual of your car would have, in most probability, mentioned one of the standards I have listed above. For all QJD / MJD / DDiS, it might be a Fiat specification (I'm not sure - Rad the manual!). If the oil in question meets Fiat's recommendation, then you do not have to worry about API or other standard. SAE rating for viscosity would still need to be followed, mind you.

To summarize - the right way to choose your engine oil is to read the manual to

1. Find the engine oil specification of your car's manufacturer
2. Find the SAE viscosity requirements specified by your manufacturer for the operating temperature ranges most suited for where you live
3. Find an oil that meets these two
4. Ignore specifications in the oil can other than those listed out by the manufacturer, even if they seem outdated!

And finally, Hyundai goes by API - my Getz CRDi needs API - CH4 or higher

Guys, I had been to the Fiat free check-up camp on when it happened a few days back in Blr. The essential oil top ups were done, the under body was checked and the car was then washed.

But, after the engine oil top-up, I somehow feel the smoothness (I mean the in-cabin engine noise) of the engine seems to have gone down. The engine seemed very smooth prior to the oil top-up. Considering that the car has done ~12.5k without an oil change, could it be that the topped-up oil might have something to do with the loss in smoothness? In the sense, does mixing a small quantity of fresh engine oil have any impact?

Good news for Diesel Heads in Chennai - Mobil Delvac 1 is available off the shelf. Anyone interested? The distributor called in just now, said he currently has 8 cans of 5 liter each, and will call me back with the pricing in sometime.

Good Amount of info there ph03n!x !!



The key is to ensure that the oil meets the specifications. It doesn't matter what the A.S.S thinks as most of them can't differentiate between a mineral oil and synthetic oil.

Please check for the oil grade and ensure that it does meet the requirements.

MJD's / DDiS / QJD needs API-CI4 spec oil nothing less.

And the 5w40 doesn't meet the requirement.

@amit1234singla,@satish - If the oil doesn't meet the mimimum API spec please do not use these oils.

Cheers

I am not sure about the API spec for the Fiat Multijets, as Fiat might have as well gone by one of their own standards.

And Mobil Delvac 1 is 5W 40 - IMHO most synth have a lower winter viscosity, making them lubricate better at cold startups.

[sgiitk]

Many companies try and put out their own standards but these are not really different fromt he API specs. Unless it is a Veyron I think API is ecoungh, may be even for a Veyron!

True, but problem is when A.S.S throws "Warranty" at you - I have known at least two TATA / Fiat owners being told that filling in any other oil except from the A.S.S might give warranty problems - this is for a Punto MJD in Chennai and a Vista QJD in Coimbatore. In such cases having proof of using Fiat approved oil, though bought from outside, might help??

Also, there are questions about TATA-Fiat using oils that are not of the latest / current API grade - could be the oil in question meets Fiat's Specs?
