I live in Hawaii and we have an average temp of 85 degrees, +/- 3 degrees throughout the year. What would be a good oil to use under these conditions? I was looking into the 15w50 mobil 1, Royal Purple, or Red Line brands.

Thanks

 

Both shops that I have delt with told me to use 20w-50 oil. I use it year round.
