Filled up the R35 tonight on my way to Knockhill with Nitro+
The only difference is that the Nitro+ contains 25% more friction modifiers than the previous V Powor formulation.
No difference in power or performance and lap times exactly the same.
However, I have been reliably informed that the Nitro+ 99 octane (RON) formulation will in the future become 102 octane with a price increase to match.
