In my opinion I would keep #75 in summer since u get 96 mpg. In the winter I'd say try a #70.. Since engine will b at cooler temps in winter u can run it a lol hotter.. Try puttin in a #70 take a long ride with it, then pull plug to see if too lean or not, then go from there.. Just make sure when summer comes around u put the #75 back in so u dont burn up engine... Personally I would never go lower then #70
