hey guys, sorry for the dumb question but i'm new to actually doing the car maintenance on my own rather than a "jiffy lube". i live in miami, fl and its hot here year-round. as you well know, in the summers it can get to 100+ degrees and in the winter, probably the coldest it will get generally is in the 50's. occasionally with the wind chill it'll feel like the 40's and maybe 2 times in the year, itll feel like the 30's. i know the manual states to use 5w30 but is that optimum visocisty for use in the hot weather of miami? thanks

 

Hmmmm, I typed oil viscosity in search up there then clicked titles only and got a lot of threads for you to peruse.

5w30 works just fine for hot climates, and florida is not a hot climate. Hell i run 0w30 just fine in the middle of the desert.

 

I follow the recommended oil specs.

 

oh its not? please elaborate what hot climate is because i thought it was?

 

just follow what the manual says

 

phoenix

 

South Florida can get hot but its mostly a humid climate.Just follow the manufactuer's rec.

 

Somewhere that normally gets in the mid teens, low 20's and hotter would be a hot climate.
5w30 is just fine
