Default VW use Castrol Magnatec 5W40 for Polo, Why not EDGE?

Yesterday, I went to a local auto part shop to get oil for my 800 (use GTX), where I noticed Castrol Magnatic oil. I was under impression that Magnatec comes as both semi synthetic and synthetic. But the guy said that Magnatec are only semi-synthetic and not fully synthetic. I have still asked him to confirm the same from Castrol.

But then whats better way to clear your auto queries than Team-Bhp. So here I am.

In October 2010, VW service station filled 500ml of Castrol Magnetic Oil (5W 40) in my VW Polo 1.2 Petrol. It was a 1L bottle which had an MRP of 970, and after adding some other taxes, it costed me 1035. The bottle with remaining 500ml was handed over to me.

Now, 500ml Castrol Magantic 10W 40 has MRP of Rs169, so if I go according to the shopkeeper and believe that 5W 40 is also semi-synthetic, a Litre of same should not cost above Rs.400.

However, a quick PM to GTO and he sent me a link, which says a few grades of Magnatecs are semi-Synthetic and a few are fully synthetic.

Here is the link,
FAQs | Castrol Magnatec FAQs

Castrol.com doesn’t specify details of 5w 40 Grade and Castrol India doesn’t even display this grade under magnatecs. So, I would like to know if 5w40 is synthetic or semi-synthetic.

Because if it is semi-synthetic, this means VW is using semi-synthetic oil in Polo and charging for fully synthetic.

However, if its synthetic and I wish it is, why is VW not using the Castrol Edge, which is their brand for Synthetic and also considering that the EDGE comes in 5W 40 grade.

@Gaurav - The Bangalore dealer had topped up my car engine with Magnatec oil and had charged me Rs.970/- for the one litre can. I really do not understand the logic behind the pricing of 5W and 10W. But since the dealer gave me a 5W bottle and recommended its use, I have been using it.

Gaurav,

I think except 5W30, all oils grades starting with 0W or 5W are fully synthatic. So 5W40 is a fully synthetic oil.

you can find this info on the link below:

The 5w-40 oil VW has prescribed is synthetic. Here's a PDF file that may help.

The key to identifying this oil is "Professional' which probably means it is targetted towards OEM and large garages/service stations.

very likely it is just a re-badged Edge!

Don't confuse the Magnatec semi-synth which is widely available here with the Magnatec Professional B4 5W-40, the one you have got from VW service centre. The Magnatec Professional B4 5W-40 is fully synthetic, thus the higher cost.

PS: Not all Magnatec Professional engine oils are fully synthetic.

So, not all magnatecs are semi-synthetic, not all magnatecs are professional and not all professionals are synthetic. Fantastic.

Anways, thanks every one. Now that we know that 5W 40 is synthic, wont it be a good idea if some expert can put together a list of engine oil brands and the different grades and the category under which they normally come. It will be of good help.

Also, why would castrol brand the same grade of engine oil under different brand. I mean 5w40 synthetic comes in both magnatec and edge. Does that mean it comes in GTX as well??

As long as it's 5W40, my guess is any synthetic brand oil should work. I've personally had great success with Mobil1 supersyn. Although Amsoil and redline are supposed to be even better - and more expensive.

That's not true.

I've used 5W20 mineral oil (Pennzoil, Castrol), and 5W20 semi-synthetic (valvoline Max life) for years - not in India though.

Quick question: Anyone know if Vento uses the same 5W40 grade as the Polo?

Thanks!
