I found a retailer selling this at under 40 pounds for 4 litres Today. It will go in my T120r as it is thin when cold so i can start it easier. Fully synthetic ester based oil normally selling at near 66 pounds on ebay or 20 pound if you buy a litre.
Been searching locally for some time for a supplier of this oil.
Normally used in race bikes and road going superbikes. Should be good enough for my old air cooled twin.
It was also 10 percent pensioners discount day at Trago Mills so i spent 130 pound on other nik-nacs and garden gear.
Petrol at 1.60 for Shell E10
