Hey OzHonda,

I'm at a point where I'd like to change the oil I'm using. I'm currently using a very thick 20W-50 conventional Nulon.

My car is going on to 227 000 kms soon and I was wondering about a different oil thickness (not sure about going semi or full synthetic)

I believe that it is too thick and I was think of going towards a conventional 15W-50.

Any help is greatly appreciated.

Cheers!
