General different oils for same engine ?

Because Opel and Fiat are different companies, with different engineers and different strategies, more or less.
My guess is that Opel wanted to eke out a couple more MPG for their Corsa, so they asked their engineers if a lower-viscosity oil was OK and they replied that yes, the MPG would improve and any possible increase in wear would be negligible.
On the other hand, Fiat designed and built the engine, I'd be more inclined to trust their engineers...

Yes, it's that Eco thing, I believe. Thinner oil shaves off milligrams of emissions, makes the fuel go several yards further. It eases starting, but some say that thicker oil sticks to the cylinder walls better when the engine has been off all night, and gives better protection to cold starts. I've run most of my cars and bikes on Tesco/Halfords synthetic 5/40 for the last ten years with no ill effects though. Oil is so expensive these days, ya gotta grab it where you can.
Rather than looking on the Castrol website, have you looked in your owner's manual?
5W30 ACEA C2 for the Diesel in there.
Edit: although I've just seen the older 2007 manual has 5W40 ACEA B4...

He might not have a manual.

If he doesn't, he can download one from:

Depends on which diesel you have. They've stopped referring to the 70HP version and only mention the 75HP version with DPF.
Now, I'm pretty sure that doesn't matter when it comes to oil, either is probably fine. I bet the revised oil recommendation for the 75HP is the reason it has ever so slightly better urban fuel consumption compared to the 70HP.

Ah! Excellent, just grabbed on for my car. Thank you.
No No No!!!!!!!
If you have a DPF it really really matters which oil you add!!!!!
The DPF collects Soot and ash. Through regeneration (passive or active) soot is oxidises, the ash is retained.
Over time ash clogs up the DPF and reduces its effectively until its fully clogged up. At this point the DPF will need to be removed and reconditioned (if pos) or replaced - they are Not cheep. There are probably back pressure sensors or other methods employed on the Panda to measure the amount of ash and light a warning light on the dash when it needs money spending on it.
During normal driving the engine consumes oil, some of which is burned in the combustion chamber.
So you can guess the extreme need for low ash oil on a DPF engine - it's nothing to do with MPG – DPF life. Chucking in any old oil will cost dearly in the long run.
Is the C2 lower ash oil than B4 by any chance?

C2 is Catalyst compatible or low SAPS (Sulphated Ash, Phosphorus and Sulphur) for use in DPF engines or three-way-catalyst engines.
B3/B4 is for use in high performance or extended drain engines. (source: ACEA)
