No, except in my bank accountHas anyone seen a difference using different grades of gasoline!?
I get about 10 to 20 miles more on a tank of gas when I use higher grade, depends on the roads I travel. The more hills and wind, the more it uses. Noticed this when taking a long trip, not driving around town. Also, I add a can of Seafoam every 4th or 5th fill up too.Has anyone seen a difference using different grades of gasoline!?
I got 13mpg with 33x10.5 and 13mpg with 35s. But have a hard time spending $100 on sensors when I haven't had any codes pop hoping for an increase.I've never hit 20mpg, averaged closer to 17mpg. I've always run 33x10.50s. But I put on new tires, 7.50R16s... and I now get 22mpg without trying. A 5mpg bump from a change of tires.
Plus my TJ coasts forever. Rolling up on a red light, I need to hit the brakes to stop in time. I used to just coast to a stop.
I'm never going back.

It sounds like you have air in the block and some effeciency issues with the radiator, a properly functioning cooling system will not vary too much, even at 110 degrees.Sounds about right where I am at. I did put a 160 thermostat in it Summer of 2017 and replaced my water pump. I'm going to change that this week. Being in Arizona at the time, simply driving a few miles to the store and home a was too much with the stock 195 thermostat. My radiator would be boiling. With the 160 thermostat it did much better. California is hot as well, but, there's something special about Arizona's heat. It'll heatstroke the toughest in a hurry. Being in California now, my Jeep runs a few degrees cooler, around 190/195. Yet, In AZ, around 210/215. (That is with the 160 thermostat in.)
I'm going to change it regardless and see what happens. Ty for responding. Larr
