Stick the reg into ECP or GSF and find out? Or use the Castrol Oil Finder on their website.


Personally, for that age and type I'd just bung any old 10W40 semi synth in. If you put expensive stuff in you'll double the value of the car, so it'd be budget oil and regular changes for me.

You'll likely find it's 0W-40 A3/B4 that's needed.

But best to put the details/reg number in here to check the spec:

You don't necessarily have to buy Castrol oil - it's the numbers and spec that matter - not the brand.

Sorry to butt in, but I have a similar question so I thought I'd put it in on this thread. I'm a bit confused because the Castrol selector above states I need 0W-30 grade oil, Halfords are recommending their 5W-30 and the Mobil site states 0W-20.

Does it matter/are they interchangable?

TIA

As already said I would be using 10w40 semi synthetic on an old Diesel like that.

As ShandyAndy says, 10W40 is fine for an old diesel. But what car have you got ? Those oils sound very "thin" - 0W20 in particular sounds very odd, I've never come across an engine that needs that. In answer to you're question - on a modern, newish car, yes it does matter, and no they're not really interchangeable. Best thing is to check in the handbook - or in a lot of cases, there's a sticker on the car somewhere, often near the oil filler cap.

I'd be reading the post.


But I agree regular changes of something cheapish is the way to go.

No, they are not interchangeable - far from it.

But as to how much it matters depends to some extent on the car manufacturer and whether the engine is petrol or diesel, the miles it has covered and the use you give it.

The first number is the viscosity (thickness/pourability) when cold and the 2nd number is when hot

If you do few miles but lots of short journeys then a 0W is the one to go for.

Plenty motorway use would call for the 30

They 3 you quote are not that far apart though - it's not like having to choose between a thinner 0W-20 and a much thicker 20W-50

But you need to check the letter code too.

A oils are for petrol engines
B oils are for diesel engines

but some manufacturer's oils are suitable for both, so will carry the letters A&B.

If you have a petrol car with a cat (catalytic convertor) - or a diesel with a DPF (Diesel Particulate Filter) then you need a C grade oil.

Then some manufacturers have their own specific requirements and approvals such as:

VW 501.00 and 506
MB 229.1 and 229.5
BMW LL01 and LL04

Clear as mud? - I hope not.

The short answer without knowing which car you have is that I would go for the 0W-30 as a good all round oil for most situations.

:doh: OOps, yes my mistake, same oil essentially though!.

For the Pug, ECP are saying 5w40 fully synthetic. £17.49 for 5 litres of their Triple QX own brand.

I'm not sure if you were talking to me here, I don't think I've asked this question before? Apologies if I have though

It's not a deisel, It's a Honda Jazz 05 Plate Petrol 1.4 if that helps? Ive just checked the handbook and it says

"It is highly recommended that you use genuine Honda MotorOil,‘‘ACEA A3/B3,’’or ‘‘ACEA A5/B5’’in your vehicle for as long as you own it. This oil is formulated to help your engine use less fuel.

You can select the proper SAE/ ACEA viscosity oil for your vehicle according to this chart:

*picture of a chart with ambient temperature and then showing range of temperatures each oil is good for inc 0w20, 0w30, 5w30 and 10w 30*

(Incidentally the temperature range for the UK would be ok for all of them(

0W-20 oil is formulated to help your engine use less fuel."

Thank you for pointing me to the handbook, looks like I've got the answer

Again thank you for the explanation, it has helped! And at least now I understand what it does See above too.
