Hi Guys,

Lots of good brains in this thread so please forgive me reviving an oldie!

I have a heap of Mobil Super 3000 X1 5w30 which I use in my Volvo XC90, I was hoping to use this in my 2010 1.6 CRDi.

The rating of the Mobil Super 3000 X1 is ACEA A5/B5

Does anyone know if this is safe to use in the i30 deisel?  I know that Hyundai call for Acea B4 - but I'm hoping that someone will tell me that th ACEA B5 will be fine as it exceeds the B4 spec (wishful thinking maybe)

Cheers

It should be fine to use going by the specs/description http://lubes.mobil.com/AP-English-LCW/carengineoils_au_products_Mobil-Supe-r3000-X1-Formula-FE-5W-30.aspx#

Not as highly rated as their Mobil 1 but seems more than adequate

Thanks Craig!

Do you know what the difference is between the Acea B4 specified by Hyundai and the Acea B5 of the oil that I have?

[CraigB]

I'm not 100% sure but I think the B5 spec is Euro emissions compliant.

Found some info here ACEA Engine Oil Specifications - oilspecifications.org seems the A5/B5 spec is for engines that are capable of running low viscosity oils so you might need to check your manual to see if it's mentioned that A5/B5 can be used, or call Hyundai to confirm.

It's an interesting question I can't answer but, there was some castrol edge titanium on special (1/2 price) not so long ago I wanted to get but was A5/B5.

On the the back of the packaging I'm sure it stated not suited for A3/B4 applications.

I don't know why or what the differences are but I took the safe option and did not buy it.

Not trying to scare you.

Thanks Guys!

I was really hoping that someone whould chime in with "don't stres B5 is a higher standard than B4 so go for it!"  Sadly it looks like they are quite different oils.

The clincher was when I had the bonnet up yesterday and noticed the sticker that mentions the Oil used must meet B4 standards.

Like I said I'm no expert on lubes but I was in Supercheap and remembered to triple check what I read. So here's a photo on the back of the Castrol Titanium A5/B5 specced oil I wanted to get and did not.

I never knew oil was so specialised until I converted to diesel engines.

Exactly, the thing is that the B5 is much thinner, and made with purpose of meeting the lowest fuel consuption demands.
You can't have it both ways so if you have that low consumption you can't have the needed protection.
Some engines, that use a5/b5 are designed slightly different, so to endure with thinner oils..
When I say thinner I mean - low HTHS viscosity
