At 95-105F I'd be draining the 5W20 and putting in something a bit
more substantial. The 5 isn't doing squat for you at that temperature.
10W40 or even 20W50 will NOT hurt the engine at that temperature - but
it might cost you 1/2 a mile per gallon.More likely about 1/10. For
the winter, you will want the thin stuff.
