I have a 94 nissan 4x4 pickup witha 4 cyl. this truck came with a 160 degree thermostat, and always runs cool. I removed the fan and added an electric fan. in stop and go traffic in temperatures over 90 degrees, I have to turn the fan on every so often, otherwise, I never use it.I have thought about installing a 180 degree thermostat, but I rather enjoy not having to worry about overheating.
You're worried about overheating with a 180? Most cars come with 195's from the factory. Even my 1981 Buick came with a 195 from the factory. In the 18+ years I've owned it the car has never even gotten close to overheating. You'll probably get better FE with a warmer thermostat.

EDIT: Your heater will work much better in the winter if you up the thermostat too. I had a 180 in Rusty for a while when he had some overheating problems, and the heater did not work as well.
I almost never use the efan in my S10 4 cyl. I gotta be sitting for a while idling before it even gets to 190 and I've never gone over 200 before a light turned green BTW I have a 180f t-stat, factory is 195

the only thermostat available for my truck is the stock 160 and an optional 180. I will probably switch to the 180 . if you have ever had a vehicle with a heating problem, you can become gun shy about increasing the running temp.
The electric fan stopped working on my Saturn about 18 months ago.
I never fixed it.
I do mostly highway driving. As long as I'm moving at least 25 MPH, the engine will stay cool, even with the A/C running. If I'm stuck in traffic I turn on the heat (happened about 3 times in 18 months) - not pleasant, but I just haven't had time to fix the fan.

p.s. I'm not suggesting you remove your fan, I'm just illustrating how little a fan is really needed. (I cannot run A/C when I'm parked or stuck in traffic, obviously)
