is this one here ok?
castrol on special

That's it.  It's a good price for what I feel is probably only one step down from the best.  It does maybe also have an advantage that it is not ACEA C3 oil.  C3 is a spec for oil to be kind to catalytic converters which limits certain additives that otherwise might be better left at non-C3 levels WRT engine longevity. 

Oil manufacturers are required to continually meet new stiffer specifications related to pollution and economy.  I suspect some of these might reduce their effectivness as... well oil.

I use this oil in my diesel and so do quite a few members, nice compromise between quality and price

i think thats what really confused me, i thought the same oil couldn't be used in both diesel and petrol 

[Dazzler]

From my understanding you would get away with a lesser oil in the Petrol model... Pretty much all the oils that are suitable for the Diesel are fully synthetic.. some "lesser" mineral oils and semi synthetics would be suit for the petrol models which I don't have such demanding requirements..

this is turning out to be quite a topic

What grade and specification does it quote in the Handbook?

[snowcherry]

i rang my dealership today and they said they use a Castrol 10w30
so i think i might get the one at supercheap if they have any left

i cant find the oil grade in the glove box manual but my 1000km oil change receipt says 5w30

[snowcherry]

not idea why my dealership uses the 10w - i tried reading up on this a bit and i just don't get mechanics at all! anyway supercheap had plenty of the 5w oil so i just grabbed some, hopefully the dealership actually uses it for me

Grade OK but what specification are they quoting?

i asked for clarification but that was all i could get over the phone. i prob could get more info out of the parts guys but thought it was just easier to buy some anyway

Page 377&378 - section 9.4/5 (in the online pdf, I thing this is global but not sure if there are localisations)

For best fuel economy 5W30 is recommended. The specs are on page 377.
