In any case, I suppose it is a case of the glass being half empty or half full. If it's part-synthetic, the other part must be mineral of course.

Tanveer,I just took pictures from the 4 litre can I have.
It says "synthetic technology" in the front and back.

[tsk1979]

Now what is synthetic technology ???
It is either mineral, or synthetic or semi-synthetic, what does synthetic technology mean?

Sam, I am not saying that your link is wrong, what I am saying is that maybe this magnatec range contains mineral oils too.
There is not just one oil in magnatec
you have GTX magnatec 0W30, 10W40 etc., and then GTD magnatec too!

Should we flush before switching over to magnatec from mineral ?

[nitrous]

I don't think so,SwathyD.
Anyways, it wouldn't harm if U flush either.

Shell distributor in Kolkata has some stock of June 2006 batch of Helix Ultra 15W40 synthetic oil .
He is willing to give around 15% discount. 4L for around 1750/-.

Considering I put in the oil now and change after 10K kms (approx 10 months time), should the year old shelf life matter ?

I'm keen on getting the stuff.

Good price, I think. AFAIK, a synthetic oil would not change characteristics sitting peacefully and unused in a plastic can for a year.
Go for it.

Thanks for the confirmation. I was even considering picking up an extra 4L for the next oil change after 10months - Mar/April 2008.
Would that be pushing it a bit far ?

I don't think synthetic oil expires. But let us wait for our lubricant moderator to give us his vishesh tipni.

[Vid6639]

oil doesnt exactly expire but it does lose some of it's lubricating properties over time. But that's over a loooong time not short like a year or so.

Basically it tends to go towards being a little sticky. One year is not a problem.

Rs.1750 for 4 litres of synthetic oil.
Do check if its semi-sythetic.U can use it this time.I would advise U against using 2 yr old oil.
So, see if any other kolkata bhpian has an oil change due and guide him to it.

He said it costs around 500 something per litre. So thats 2K for 4. Discounted price is 1750/-. A new jar of 4L was quoted at 2300/-.
Am sure it's synthetic, since his first remark was - "Sir are you going to use it in your Mercedes?"

Yes, have already spread the word among Kolkata members.

[tsk1979]

Do not buy oil older than 3 years, thats about it. So if you get a July 2006 batch oil for so less go for it!

My Santro 2002 model has clocked 73,000 kms.
I want to try out Mobil 1 for my car.
But i have read thro the posts where the members have suggested Engine Flushing before switching over to fully synthetic oil.

My car history is as follows:

Purchased the car at 44,000 kms in MINT CONDITION
Since then using Castrol Magnatec oil, oil change strictly every 5000kms
At present using Servo Engine oil since the last 8000kms (Oil changed every 5000 kms).

But since my car has run 73,000 kms, it will be 75,000 kms when i change over to Mobil 1 oil.

So is Engine Flushing compulsory at such a high mileage, as there is a risk of the engine oil seals getting damaged as told by some members, also even when i have strictly maintained the oil change interval at 5,000 kms?

Use a 15 minute idling flush, not the 5 minute brand as they are more harsh.
You can go for Mobil 1. For your santro there are other options too like Castrol EDGE(600/liter), Shell helix Ultra(600/liter) etc.,
