Toy book says 80w-90 or 85w-90 for 0 degree F or below. Straight 90 wt for above 0 degree. Here in central Fl, its never below 40 F and never below 60 when I drive. Typically 75 tp 95 F. However, I cant find straight 90 wt anywhere. All that I can find is 80w-90. Is that ok? Also, its carquest brand. It is API service GL-5 which is what toy calls for. OK to use? This will be my 1st and maybe only diff oil change. I do want this vehicle to last forever.
