Is 5w-40 any good for using in the UK?

 

That's the recommended viscosity here in Sweden so should be good for UK also
Edit: You shouldn't post these oil topics in this part of the forum btw, probably better of in Under the Hood.

Wherever you live really does not affect the kind of oil you use. HOW you drive the car can.
A big issue is start up wear. A "0"W-XX is the best out there for that. Once the oil warms up to operating temp, say a 30, they are all the same viscosity. I use Mobil! 0-30 and I am in a warmer (for start up) climate.

 

All of my 5 cars listed below have used Amsoil since 1st Oil Change....a combined total of 457k miles AND 50 years of combined service.

03S2k,02Z06 & 96GST use 0w30 while the 02CRV and 13EXV use 0w20.

I've been using Honda recommended 10-30

So you guys recommend 0-30?

 

Yes. Best quality you can get. Synthetic is better than Dino.
