Re: 10w30 Oil to thin for summer use above 86F
I've always used SAE30 and never had an issue (knock on wood). The only exception to that is in the winter when I was using my lt4000 for snow plowing, then I was using 10w-30. All the manuals for my machines say use SAE30 and that's what I use. All my stuff is over 10 years old though, newer machines might be different. My recommendation is do what the manual says.
