10w40

Guys you may have read some of my posts on here about the engine change I done. I genuinely think my problems started when I changed the oil to 10w40!! I had bottom end failure resulting in a very expensive new engine fix. I have spoken to a few mechanics about it and they agree. I ride bikes...

I use Shell fully synth Oils in my race bikes.. Ok to use 10W40 semi in an RSV? Thanks in advance..
