This run was mostly longer trips at around 35mi each. Mostly winter driving with a bout 5 minutes of idle warm up before moving. There were a few drag passes on the this OCI with a mixture of mostly pump gas(93-octane) and Torco unleaded race fuel. No other additives to fuel or oil. I inquired about 5w30 which is why it is mentioned in the report. UOA done by Blackstone Labratories.
