Hello everyone,
I am choosing the next oil for my Honda CBR F4i (2001 year) and I am hesitating between JASO MA and JASO MA2.
The manual for F4i calls for API SE, SF, SG oils without mentioning JASO specification. Since my bike does not have catalytic converter I may stick with JASO MA. I've read somewhere that because of catalytic converters the JASO MA2 spec limits phosphors and this results in less engine wear protection.
As of now I have been using Castrol POWER 1 Racing 4T 10W-40 API SL, JASO MA2 with OCI 500 - 2000 km on a yearly basis. Now I am thinking of switching to Valvoline SynPower 4T 10W-40 API SG JASO MA.
I wonder, will I get more engine wear protection with JASO MA? I can see in Lubrizol comparison tool that API SL should do a better wear protection, but something tells me that this is only theory.
Also, if I am worried about wear protection, should I hunt for API SM? I can also get for the same price Valvoline SynPower 4T 10W-50 with API SM and JASO MA-2 but it's viscosity is slightly higher than the one recommended by Honda.
