What’s the difference between these two 0w30 oils?

[Raymond Lin]

Castrol website recommends the Castrol Edge A5/B5

Which is the same as the top result in Eurocarparts. However there is also another 0w30

Are they drastically different? The manual doesn’t go into that much detail besides the grade.

Probably nothing at all

 

[HoneyBadger]

One is for a Volvo

 

[Kenai]

It'll be different manufacturer spec approvals, so they will probably have slightly different properties/additives.

 

[dlockers]

Looks like one is for vertical engines and the other is for horizontal engines.

 

[Simon]

Edit. I was blind with original. Left oil is A5/B5 (2.9cP HTHS) Right is A3/B4 (3.5P HTHS)

So one is a thin 0W-30. The other a ‘thick’ 0W-30

You need the A5/B5 version

 

[Nasher]

I bet they are exactly the same. Castrol Edge is Castrol Edge.

 

[Simon]

I bet they are exactly the same. Castrol Edge is Castrol Edge.

No bets needed there are many different viscosities

 

[decto]

They are two different specifications, the Volvo oil has an A5/B5 suffix

Differences in viscosity, Ash etc.



Edit.... I must really be bored

Updated my original reply

Is worth checking the detailed specs.

Chances are getting the "headline" specs correct and you'll be fine.

The Mrs Fiesta for example, goes through a fair bit (maybe a litre a year) if you don't put the specified ford spec oil for that car, with correct one hardly any oil at all is lost.

Same of my motorcycle, although with that is use rock oil, and rock oil do a "guardian" version of the same spec, which does make a difference.

 

[Raymond Lin]

Thanks guys, I picked up the one with A5/A6 in the label.

Get the 4ltr works out much cheaper than the 1ltr ones..

Yes, but that doesn't really fit well in my boot lol

It's just when I need a top up when i am out. I don't need more than a Litre a year between servicing.

Get a 205l drum !

 

[Finglonga]

Use your old 1ltr bottle and fill it from the 4ltr bottle.

Maybe now you have the correct spec oil you won't.

 

[Raymond Lin]

It has the correct spec at service, every year a we round Feb at a Volvo specialist, usually around late summer it will throw up a low oil warning. It’s just burn a bit of oil. Correct spec oil. Unless you are suggesting they got it wrong? But then right spec oil to top up won’t do much when it needs like 5.8L.
