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:
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!
