The world's only castor-based oil formulated for today's modern electronic fuel-injected two-stroke engines including the KTM Transfer Port Injection (TPI) System. The Blendzall TPI formulation translates into a bike that simply runs better, cleans out faster, doesn't leave behind that black oily residue and it smells great. Get added lubricating qualities found only in castor oil, preserving internal engine parts - all because Blendzall has the film strength to withstand the lean oil ratios configured in electronic two-stroke fuel systems. OEM safe, warranty secure.

Compatability: Ultra TPI does not mix with conventional and synthetic oils. Be sure to fully drain your oil tank, lines and pump before adding Blendzall Ultra TPI.
