98 Octane

Installed new drive belt and tightened all pulleys. NO MORE KNOCK YEEEWWW!!!!!

Previously I was using PENRITE 10W40 oil due to the hot climate of QLD, which I suspect may have been causing lubrication problems under load. I have since done a complete flush of the system and refilled using PENRITE 5W30. Furthermore, in addition to the thinner oil I filled have the petrol tank with 6.5L of UNITED E85 mixed with standard Unleaded 98.
