Hey everyone, I just got done rebuilding my 2.5 cyl. in my 93. Its running smoothly, but getting horrible gas mileage. The story is, my last engine dropped a valve and destroyed the head and cracked the sleeve in the #4. I picked up a 95 2.5 cyl for dirt cheap, and used that block/head, but most everything else from my 93. The only difference is, the 95's block was already .050 over, so after a trip to the machine shop, it left .060 over, which is how i rebuilt it. it was a complete overhual. I've got about 300 miles on it now, but its only getting about 12-13 mpg, which is horrible. my last engine, not too long before it dropped the valve, was getting 13-15. I was hoping to getting near 20 like my old motor USED to get. Could it be the .060 bore?
what are your thoughts? As far as i can tell, everything is re-assembled correctly. I'm asking for your advice on what to triple-check.
other info: I'm using a 180 thermostat instead of a 195. is that causing bad efficiency? the engine isn't heating up unless im on the street in traffic. at highway speeds and even around town it won't heat up. I know these engines run pretty cool...its engaging my electric fan at about the right temp, so i have no reason to believe its a bad guage.
Thanks for any advice or reccomendations

everything is STOCK, right down to the airbox. so I'm not sure what else beside the
with a 180 t/stat should heat up to 180, if it doesn't change it as it means it is getting stuck on open. That will cause a lower mpg and since we're talking 1 to 2 mpg that sounds right.
