You can use either. The numbers refer to the weight of an oil in other words the viscosity of the oil at a given temp. The number before the W is the viscosity when cold. numbers after the W are viscosity when hot.

0w30 is a better performer when engine and ambient temp is colder. the oils have the same properties when hot

Yet another stupid HUKD comment.

Probably be a witchhunt

which asda store

Probably be a witchhunt

They had the C3 one in Asda Telford but sold out last week! That was £7 too! I was after the C2 too! Ha

Scanned receipt ?

Asda have been reducing these for quite a while, few deals posted over last couple of months. Got mine for £10 few backs but YMMV.

Nice one:) thanks !

Scorchio!

Great price, well worth stocking up if you can get it. C2 is the one to use in the euro 4/5 spec Ford tdci engines. Low ash content suited for DPF's

Let me give you some heat brother. That's a cracking price if you can find it

£28.00 in Asda Gosforth. Boo.

No bloody way??!

Will this be suitable for a Mazda 3?

check with ur reg on the castrol website, trade price on these us over double this! must be a misprice

Not necessarily as misprice. Have seen Asda do the A1 and A5 stuff at the same price. It seems to crop up every so often not sure why but grab it while you can.

Darn I need C3.

I've been pleased to pay £20 for this when on offer in local Tesco's. Ridiculously cheap.

Amazing price

Heat from me but £28 for all Magnatec near me.

This is a great price for this. Great find :sunglasses:

But castrol is terrible oil :smiley: if you have older car is fine

Depends on year and model I guess. 2009 1.6 TDCI is A5 though according to the manual

i need c3 low saps.......pants

Genuine Question. If different cars use 5w-30 but the only difference is the suffix e.g C3 v C3 or A1, is it really going to be a noticeable difference?

Great price, thanks for sharing OP!

No completely inaccurate, a lot of their oils are 2 grades behind the latest spec, which is scandalous considering the premium you pay for the brand name. However this one is the latest SN spec, its a very good deal.

full price in Benton Newcastle but local Tesco had the much better oil only £3 for litre bottle the castrol edge 5 30

Just to add if you value your car and want the best go for 0w30 as lot of ware occurs on initial start,every little helps.
Worth it for a few more pounds,I even put Mobil one in a Hillman Imp when it first came out many years ago.

Good spot OP, I'll take a drive over to the local Asda this eve.

good find, heat.

Can't that be too thin though?

While what you say above is correct it also has its downsides. On an old worn engine moving to a thinner oil can be a bad thing. The tolerances may have become set for a grade of oil over the cars life. So you may find it suddenly starts using oil. At best its a pain that you have to buy more and top it up. At worst it starts burning more kills your cat and the first you know about it is when the MOT tester tells you the car has failed. You spend lots of money on a new cat only to find the following year the cat has been killed again.
So rather than spend £40 on a can of Edge 0-W30 stick to what you have been using and buy the cheapest that fits the specs you need and change it more often.

Thanks for your explanation, appreciated :smiley:

was the 10-40 on offer or just 5-30?

Thanks op, they didn't have this exact one left in the clearance section in my Asda but did have the Castrol Edge Titanium 0w40 fully synthetic (Gold Bottle) 4L at £9.50. Bargain as its £40.99 in Halfords. I have one happy other half.

Nothing in Asda Mitcham but they did have the 1L one for £9!!!!!!

Just got from Asda Inverness. Marked as 14 but scanned as 7. Thanks so much for posting

Most likely (99.9%) just a one off to keep us coming to spend our dosh.

Yes. I spent a lot of time trying to find the correct oil for my 2011 tdci. Pages of acea specs & out of date ford specs.

I wouldnt put 0w30 in a high milage engine though. It'll almost certainly find its way out through the seals

​u paid 16 for a SD card? its better be 128gb

I paid £26 for 5w-40 quantum at vw for my 1.9tdi
did anyone use this castrol one in vag 1.9 engine?

Great price and even better it's in my local store.

This is pretty good advice. It is always better to use cheaper oil and change it much more often. I agree with this poster that it is not a good idea to change to 0-30W for an older engine, stick to the manufacturer's specification.

Very nice
