I don't think Castrol EDGE is available in the grade you've mentioned.
But, the Castrol magnatec does come in the 10W40 avatar. And it's an oil for petrol engines.
Stick to Mobil Delvac MX.

Thank you Nitrous, It was a Golden colored 5-ltr can. However, since it is already running with that engine oil, what would you suggest ?
1. Flush the engine and get back to Mobil, or
2. is it OK if i run on castrol for this time and change it to Mobil at the next 5k service ?

Cheers,
Rajesh

If its a golden colored can, it should be the EDGE which is fully synthetic.
Can you post a picture of the can?
How much did it cost?

You can go ahead and use it. No issues. Change it after 5,000 kms.

Castrol EDGE may be a great oil for Petrol cars, but for Diesel it meets API-CF4 specifications, which are pretty outdated.
If you have a CRDI, I would recommend using atleast API-CH4 engine oils.
Even if you have a non common rail engine, using a higher grade diesel oil (API-CH4 or higher) will protect your engine better, as the diesel available now has low sulfur content, and can therefore shorten engine life.
Using a higher grade engine oil will protect your engine.

Synthetic engine oils designed for Diesel engines do exist (API-CI4 grades also available), but they are rare.

@Nitrous: Unfortunately I dont have the picture of the can, it paid around 380/ltr. I dont think it is synthetic, read somewhere that Sysnthetic costs 1000 + ? ltr. Please clarify :(

@tsk: I have IDI Bolero. I was always using Mobil, but this mech to whom i went this time has some tie up with Castrol, so went per his suggestion (Om Sai Motors, Near Cosmos Mall).

Can I top up with API CI4 Mobil Delvac MX if the existing engine oil is API CH4 Castrol GTX Diesel? I am going for a trip tomorrow and just noticed the oil level is little low (between high and low). I have a can of Mobil delvac MX which I could use for top up. The engine has run approximately 5.5k after the last oil change. Thanks.

Technically you can and practically no harm should be done ^^^ but ideally avoid mixing oils.

Based on the recommendation in this forum I changed my engine oil to Mobil Delvac MX. My car has run 92k+. I was using Castrol GTX diesel earlier (company recommended oil).

Is it okay to keep Mobil Delvac MX or should I change it back to Castrol GTX diesel?

Also, what exactly is this oil seal leakage? How expensive is it to repair?

Default High detergent oil & leaky seals ?

@TSK, I'm not clear about your above point :
1. how does the higher detergent affect the seals ?
2. In other words, does using high detergent oil (well) before the 90000's not affect the seals later ?
3. Or, does such oil affect only leaky seals ?

1) By removing carbon deposits deposited on the edges of seals which prevent further deteriorating of seals, by using high detergents the carbon is removed and if seals are not in good condition the oil will leak.

2) Yes, if you are using those oils from 20-30K then the carbon deposition will not be as much on the seals, thereby you will know the actual life of the seals.

3) Leaky seals does'nt need any further detergent, they will leak whether high-deter. oil used or not.

Above points might need some corrections.

Just completed 1300 Km and would like to get the oil changed. The owner manual specifies "oils with performance level API CD CC MCPD2" .The vehicle in question is a Palio Multijet.
Which mineral oil would be the best for the change.

Help please. Should I change the oil immediately or continue using it?

Since your vehicle is running fine with Delvac, keep using it!

Its oil change time. Delo has shut shop in India and Mobil Delvac MX is not available anywhere. Car has run 90,000 kms.

What are the other diesel engine oils (mineral) with CI rating ?
