I just got my report back and both tin and lead are higher now after running Redline 15w50 for two fills with mostly track and HPDE use
So now wondering if its already time again for another rod bearing job.. they were changed with OEM ~16k miles ago. Last report (first fill of trying RL 15w50) BS noted Tin was higher, while all my previous reports w LM 10w60 were glowing and engine was wearing good according to them. Im now currently back on LM 10w60.
