5w30 is perfectly adequate for the UK climate... I’d stick with that. There’s no need to change to another viscosity really, but you could use 5w40 if you really wanted to.

Personally, I’d stick with 5w30 though. Just make sure whichever oil you buy is the correct spec, such as A5/B5 for example. Check your owners manual to find out the right spec for your vehicle & use that.

No , the correct volvo specification in UK is 0w/30 A5/B5 since the D5 was introduced in 2002. this is to comply with fuel consumption and emission regulations ... it will give better fuel consumption than 5w/30 Hand book specifications are way out of date ...

Whys it have to be so complicated.

Doesn't help that the industry changed it's grading to really screw with you

I take it that if I went to Volvo Parts desk, gave them my Reg and said I'd like oil please, they supply me with 0w-30 which is Castrol Edge A5/B5 in a different bottle?

I've checked on the well known oil manufactures sites, 2 say 0w-30, and the 3rd (Shell) says Helix HX5 15w-40

I can't say I've noticed a different in economy in my XC90, it's poor at the best of times, 34mpg average is it's best on a long run. I haven't burnt as much, in fact in 12 months I've not had to top up.

Only added 5w-30 as I did see an older post from Clan on the Jun 19th, 2016, that says to quote:

volvo have never recommended 5w/40

on the pre 2005 models with 12000 mile service intervals it was 5w/30 and on volvos oil chart is does say do not use 5w/40 for what ever reason .

the 0w/30 came along with the change to 18000 service intervals ...long life oil .
Was I right or wrong after reading on I don't know

I guess if I buy this bottle with A5/B5 written on it, then i'll be safe!

I’ve used 5w30 A5/B5 for ages... its fine for UK climate.

I haven’t noticed a difference in fuel economy by using it instead of 0w30 either.

It's where you have to get it these days, at least since the unicorns stopped crying.

For what its worth, I just type a search for Genuine Volvo service kits at the well known auction site. I have always found genuine Volvo dealers out there trying to out do each other price wise. Just give em your reg and they will come back with a price which I have always found favourable to my local factors where I have an account and get a good discount.
At least you can sleep easy knowing that the oil is what Volvo recommend.
I know its got Volvo on the container and appreciate they don't "make" oil but it keeps me happy knowing its what they want me to put in.
Last service, kept a note of the part numbers for the 1 Ltr bottle and the 4Ltr bottle so will try a search on google that way next time to see what that brings.

I know its all very confusing and people get different info which they have to decide on what to do.
I went through exactly this to start with when we bought our XC70 so searched Genuine on line and was surprised at the deals out there.

Well the debate was informative. I have low miles (40k) xc60 with the 2.4 diesel. My miles will be 7k a year. I plumped for the Mobil 3000 x1 FE 5w30 and will change every 12 months.
