Oil for a K4M?

[banana_hammock]

Been told to use 5w-40 fully synthetic, but that doesn't sound right to me. What do other K4M owners use?

yeah that or 10W40 if yo're being cheap

Good to know there's a choice! Might top it up with 10w40 and then do a proper service in the summer. Thanks!

10w40 will be fine or get 5 litres of 5w40 motrio oil from Renault for like £12
