Have a Honda 135 600hrs looking for a easy to find 10w30. Manual says Honda oil or API-SG,SH,SJ oil.
I used Quicksilver this year but read on this site that it's not as good now because it's now approved for catalytic converter motors, less shear additives..........to much info on this site.
Something with a least 3.3 hths which I read you need for shear on 4 strokes......guess where I seen that?
Only thing I could find with SJ rating is Castrol 10w30 at Walmart, could not find hths on it but I read 5w30 had 3.1 and they guessed 10w30 was a least 3.3.
Or 10w30 rotella but I winter fish with water temps sometime middle 30's didn't know if to thick?
Not much conventional oil rated SJ that I could find......Thanks
