All my local dealers are out of 10W-40 oil and all they have is 10W-30. I was wondering if this would be okay because in the Suzuki Manual it says that 10W-30 is only good up to 86 degrees F. I live in Kansas and it defintely gets hotter than this during boating season. If I use the 10w-30 will it hurt my engine if it runs in weather hotter than 86 degrees F??? Thanks.

The charts I have show 10W30 good up to 95 degrees.
