I discovered I had two old Titan Labs analysis kits laying around, and since I've had these kits for years I wasn't sure if they would be honored if I sent samples in. I took a sample from my ZX with only 660 miles because it wouldn't break my heart if I didn't get a response from Titan. Much to my surprise they did respond, here are the results. 1994 Kawasaki ZX-11D 1052cc Oil: Mobil Delvac 1 5W-40 (with maybe 4 ounces Amsoil 10W-40) Filter: Kawasaki OEM miles on oil: 660 miles on unit: 50000 Cr 0 Cu 5 Fe 8 Pb 1 Sn 0 Al 5 Si 1 An 0 Ba 34 B 50 Cd 0 Ca 1728 Mg 505 Mo 19 Ni 0 P 931 Ag 0 Ti 0 Zn 1039 [email protected] 12.3 Fuel Soot .2% Water N Fuel N Antifreeze N I took this sample because I was a bit curious if there was anything that would pop out. For maybe 50 miles prior to this sample, when the engine was fully warmed up, and at idle only, I would get a low oil pressure light. The bike is parked, but come springtime I will have my mechanic check it out. For such low miles I would have liked to see wear be lower, but I'm not real worried. Sunruh, how do you like that viscosity after only 660 easy miles?
