Don’t over think the Fiat standard, your engine will run fine with any good 5w40 a3/b4.

VS

Liqui Moly Leichtlauf HC7 5W-40, this complies with A3/B4, but not Fiat 9.555535-N2

This one is easily available

Normally the oil will be 'biased' towards one. In a Diesel you need more detergents in the oil. You will find the ratings poor is one of the disciplines. So even though the oils can be used in either I will still avoid them in the 'wrong' discipline.

For light duty diesels - smaller engines and primarily city and light highway use - dual use oils are just fine. And if there's anything modern oils from well known brands aren't short of, it is a wide range of additives. A3 b4 5w40 is in more or less the same ballpark as the Fiat standard and should do fine. Finding any Fiat standard is comparatively rare because they took a decision not to certify too many third party oils.

Shell Rimula R5 seems to be available in India and is CK4 rated.

Hm, this is the first Mahindra issued manual I've seen (for an XUV500 sold in the UK and compatible to Euro 6 specs) that suggests alternatives for Maximile oils, and gives you an idea of what spec they use.

https://www.mahindra-tis.com/incl/?f...o6_2016_uk.pdf



So Maximile FEO is essentially a 5w30 ACEA C3 or better. The ACEA spec this needs is essentially a mid SAPS extended drain interval oil, which is how they're able to make that change oil at 20k km claim (the next spec that fits mid SAPS C series is ACEA C5).

Hence its use in both their Petrol sedans as well as Diesel SUVs. The other brands they suggest such as Shell Helix Extra also carry a GM Dexos2 certification.

Searching Amazon for ACEA C3 you have Mobil1 ESP 5w30, Castrol Edge and a couple of Liqui Molys. Further there's a whole bunch of others such as Idemitsu that have such a certification, just check the specs on the back of the oil can.

Similar specs for Brake oil (DOT4 SAE J1703 FMVSS NO.116), coolant and manual transmission oil are available to help identify 3rd party brands.

Bit the bullet & switched over to the Amsoil Signature Series 5w30 on the Liva. The Delvac1 did a great job, very happy with the same and I realised one thing. It actually helped keep the mileage to a healthy figure at a time when the past driving year had even more crazier traffic than previous years. Gotta give it credit. Almost 3+ litres came out. I did use the STP Oil Treatment with the Delvac, as an experiment. It did help to a certain extent.

And thanks to the wonderful folks at Amsoil who gave me a good deal. Had to buy 5 bottles as they didn’t have a gallon can. Also the Liva takes in 3.9L. I have one bottle remaining. If anyone wants let me know. I have just used 150ml from the same. It has 800ml remaining.

All set for the summer and shall keep y’all posted about this experience. Last but definitely not the least, many thanks to Sumit for enlightening me about Amsoil. Cheers mate!

Using the link provided, went to the Shell Rimula site and observed an interesting thing.



Oil drain interval of up to 1 lac km! Is this a typo?

Cheers !

No that’s not a typo.

Volvo for number of its heavy duty engines has been allowing 96,000 km drain interval as long as the oils meet VDS 4.5 standard.

Detroit Diesel offers 65,000 miles (104,000kms) for its DD13 series of engines & 75,000 miles (120,000kms) drain interval for DD15 series of engines for over the road application.

PACCAR’s MX-11 & MX-13 engines also come with 120,000 kms drain interval.

The oil drain intervals can be pushed even beyond these limits if the truck or fleet in question is on an “Oil Condition Monitoring” program where an oil sample is taken at predetermined intervals and tested for wear metals. It is a norm for the fleets in North America/Europe to be on such programs that are either offered by a third party vendor or an affiliate associated with any of the oil majors.

Shell operates in 140 countries around the world and their heavy duty lubricants have been tested extensively for extended drain intervals.

I’m sure with a number of major international players in the heavy duty segment operating in India now, these drain intervals are achievable provided fuel quality can be ensured (having worked for an Indian Oil major for 10 years I know fuel quality & norms both are a problem) and oil condition monitoring programs become a norm rather than an exception at least for the fleets that have a large number of trucks.

I must also emphasize that the high drain intervals of the kind that I have mentioned are limited to heavy duty diesel engines and are not for applicable for the passenger vehicles (diesel or gasoline).

Another factor that needs to be kept in mind is that the sump of a heavy duty truck engine is much larger as compared to that of a passenger car even as a proportion of its cubic capacity so the additives that will be depleted over the course of the time are also more in quantity. A good example will be; a 2 ltr. American/Japanese or Korean engine (Passenger car/SUV) will have a sump capacity of 4 odd litres and a drain interval of 12 to 16,000 kms. whereas a BMW/Audi/Mercedes Benz 2 ltr. engine will have an 8 ltr. sump and a drain interval of 25,000 to 30,000 kms. Now off course you have on-board oil life monitors that dictate the oil drain interval however given similar conditions a German engine will require an oil change after almost double the mileage as compared to an America/Japanese or a Korean engine because of its larger sump capacity.

Trust this helps.

Add to all this, more robust oil filters. Bypass filters as an added option are fitted in many US based trucks to increase the drain interval. https://www.machinerylubrication.com...ass-filtration

With proper used oil analysis as a guide (not as easy to get in India, and fairly expensive unless you have a fleet of trucks or diesel cabs to justify the cost), you might even be able to swap out the existing oil filter even in your sedan or SUV .. the filter will give up far before the oil gives up. Top up oil lost during the filter change, run for a further distance. But do that only with a proper used oil analysis and periodic topups of the oil during the oil change interval.

Sorry, not trying to sound rhetoric, but our XUV 2018 is fast approaching 10k odo mark. Our last 5k service got us Mahindra Maximile , but at 10k we feel it's time for some serious lubrication.

The feelers from this thread is that we are favoring Mobil1 Delvac, but i am not sure if it's Synth or extra drain period Mineral.

Kindly need help in this grey area.

[hserus]

In diesel engine oils the mineral and synthetic difference doesn't matter as much as the api and/or acea rating does.

Mobil 1 Delvac and Amsoil 5w40s are fully synthetic as it happens. Delvac is still currently CI4+ rated, Amsoil is CK4

You could use any CI4+ or higher rated mineral diesel engine oil and that would work just fine, there's a wide range available in the market.

Try Amsoil. You won't regret. Same with Delvac but the former is turning out to be a lot better. And along with this might as well try something like the STP diesel Fuel treatment, Amsoil Cetane Boost & Diesel Injector cleaner. Great products!

Don't use those additives. Use the amsoil by all means but just fill high quality fuel - which means Shell, Reliance, Essar or only from known good pumps in BP / HP / IOC

I do that but why not use these additives?

Snake oil of dubious effectiveness in general. Most if not all manufacturers and even oil vendors will recommend you don't use them. Especially the friction modifier types like Ceratec etc.
