I use Triple QX 5w40 from Euro ?
It's RN700/710 spec so it's good enough for me.
About £18 for 5L
Regular changes with a cheaper oil is better than leaving a decent brand in for longer, IMO of course.
I doubt many use 5w50, not that common of a grade. 10w50 is the usual next grade up.
A thicker oil is just masking the problem though i think, you're better to look into why it's using it in the first place and go from there.
