@avinash_clt:

The Motul 8100 X-Clean is hard to get - I tried sourcing it from my neighbourhood Motul dealer, he wasn't able to. Motul 8100 X-Cess, however, was available.

This Mobil 1 5w30 which is 507 00 is backwards compatible with 505 01.

What are the implications if any of this change?

Should I change it back to the old oil.

Also I have a sealed container of Mobil1 0W50 manufactured in 2014. Is it still usable?

Please read your owners’ manual carefully.

There are two kinds of service intervals for the 2.0 TDI engine; long life service and inspection/fixed interval service.

For long life service the specs are VW 506.01/507.00.

For inspection service/fixed life service which I believe is 15,000 kms or one year the oil should meet either of the four VW 501.01/506.01/505.00/507.00 specs.

As for the oil in your possession there is nothing like Mobil 0W-50, either there’s Mobil 0W-40 or Mobil 5W-50.

Mobil 0W-40 meets the VW 502.00 & 505.00 specs. Mobil 5W-50 meets the older 501.00 & 505.00 specs.

Castrol Edge 5W-40 meets VW 502.00, 505.00 specs & I don’t see why you should change unless you have a specific preference for Mobil.

Hope this helps.

Heard the same when I enquired for X-clean at a local dealer. I however plan to get a communication from Motul India as the product is listed on their website.

Mobil1 ESP formula is a superior oil. I am however not sure of going from a 5W40 to a 5W30 grade oil, especially since the engines have been running on 5W40 all the time. Unlike VW 507 00 (only 5W30), VW 505 01 was available in both 5W30 and 5W40 grades.

I understand that this is an old catalogue but I'm wondering why the ambient temperature being too high is relevant at all?

For any oil marked xxW-yy, the number xx determines how well it performs when the oil temperature is 0 degrees C (which is of relevance when you start up a cold engine) and the number yy determines how well it performs when the oil temp is 100 degrees C.

As far as I know, the oil temp at which modern engines operate is fixed and is usually around 100 degrees C. On a hot day, the radiator will work slightly harder but as long as your engine is not overheating, it will still run the same fixed oil temp. So why does ambient temperature come into the picture?

As I've mentioned, Tribology has moved on a little bit but earlier on ambient temperature had a direct reference to manufacturers recommendations. The main reason was (a) hot ambient temperature would break down oil beyond a certain level or (b) it would remain more viscous than required for a longer time in colder temperatures. And while cooling systems are supposed to ensure a specified operating temperature this was a second level of safety so as to avoid a single point failure scenario.

Which is why I have stated earlier - do not use VW 507.00 in India as that is as per the EU standard - VW recommends Magnatec for the same engines in India which isn't VW 507.00.

I had submitted a querry through Motul India website regarding the availability of X-Clean 5W40. The local retailers were providing only X-Cess 5W40 (does not conform to VW 505 01). To my surprise, they responded back within half an hour, confirmed the availability of X-Clean 5W40 and provided the contact of their Area Manager based out of Cochin.

I would be using it when the next service is due for the Polo GT TDI. Meanwhile a friend in Cochin already got in touch with the Motul representative and bought himself 5L of X-Clean 5W40 from the warehouse. Pictures attached below (apologies for the poor quality). So yeh, the oil is available, contrary to what retailers say

That's nice to hear! In my case the authorised retailed called up the warehouse in front of me and there was a lot of delay / dilly-dallying at the other end. Looked like they didn't make an effort to check the availability.

Let me know how this oil works for you. I'm on Mobil 5w30 I linked in my previous post right now.

Would be interesting to know your experience with it. How much does it cost?

Just ordered 5 litres of Mobil 1 from Amazon for my upcoming service.

Drive on,

My friend currently got 5L of the Motul X-clean 5W40 @ Rs.5075 ( 5 x 1L bottles). I couldn't find any other oil other than this in the aftermarket, which conformed to VW 505.01 and 5W40 grade.

While the Castrol Edge 5w40 isnt normally VW 505.01 compliant, I have noticed a grade that is recommended in other Videshi TDI forums.
The information and the label(Google'd it) mentions it is compliant. Any experiences here as I plan to use this for my yearly oil change at a FNG soon.

I would take the description on the Amazon listing with a pinch of salt. The best thing is to look for the physical label on the bottle itself. Till now I haven't seen any Edge Titanium 5W40 in the retail market (non-imported bottles) that has VW 505.01 approval. I had purchased odd 3 or 4 bottles, in different instances and different locations.

Also there are at times slight changes in the specifications of the, say, same Castrol Edge 5W40, based on the markets they are supplied in. This would be more evident if you go through the technical data sheet section of similar Castrol oils in different markets.

Even I suspect the same and have requested the seller to send me a pic of the actual can.

@Roomy: what you should be looking for is this: Castrol Edge Professional VW 505.01

A spares society might be stocking these. I got some last year from the spare society near the Nandi Utrust showroom on Hosur road.

Thanks Naresh, could you also share the co-ordinates of the same if possible. I'll go over and have a look.
