Another oil thread, sorry!!
Got a little concerned about the oil being in my Busa for more than 5 years, trusting my gut but reading all the hogwash on the internet made me a bit uncomfortable. So we changed and had the old oil analysed.
All is perfect!!! Analysis below.
BTW, this is the first oil I have used where the Busa gearbox does not knock the beejebers out of the viscosity and the oil stayed 100% in spec. Mobil 1 and Shell Helix drop to a 10w30 or even below in less than a 1,000 miles.
