Been doing my homework and downloaded "How To Select a Motor Oil and Filter by Fitch, highly recommended for other Newbys BTW.
My application is a little unusual so please bear with me whilst I elaborate:
Vehicle is a 1969 650cc Triumph Trophy motorcycle, my pride and joy and almost original, It does no short journeys and I ride it sympathetically, though
The std oil filtration system is gauze strainers in the dry sump scavenge pickup and another in the oil tank on the suction side, pretty crude you will agree.
I have fitted a Norton Commando spin on filter mount to the return to tank line, modified to accept available 3/4" UNF filters [std was 15mm metric thread]
Been looking for very high quality Fleetguard LF3460 equivalent, may have found it in the Amsoil SDF57 and hope that I have because premium filters are hard to find in Australia.
Running Mobil 1 5W-50 and appreciate the strengths and limitations of the oil but James Fitch's excellent work has got me wondering re how can I get SAE J1858 data on full flow filters ?
I realiase that my choices are limited with full flow filters, there is no room for an additional bypass filter, even if one were available in the small size required but I would be happy to import a dozen [box] of a better filter is they were available.
It would be nice to get even a 20% capture rate at 8 micron if I could.
I have run short of information guys, any assistance would be appreciated.
