I own a used 2003 Honda Civic lx... with about 66,000 miles. I can get 11.5 gallons of gas in my car and was getting 350 on a full tank which. ='s 30 mpg city/hwy average. I went to jiffy lube and got the fuel system cleaned ( for what I'm sure was the first time ever). How many more miles per gallon more will i get based on of course if all other factors stay constant (i.e. same rout to work, same speed average.. etc.. etc.. etc...) I'm just looking for a best educated guess? I think btwn 34 mpg and 38 mpg. I'm shooting for 400 - 450 miles on a full tank of gas. Anyone who answers my question will get a follow up answer from me so that if it ever come's up again we'll all know how to advise questioner's.

Don't forget to put the maximum 36psi cold tire air pressure in the tires to get the best gas mileage. Using Mobil One full synthetic engine and manual transmission oils will also help increase gas mileage.

Unless there was a problem with the fuel injectors before you had them cleaned, I doubt if you are going to see much improvement in the mileage. I would expect the mileage to stay the same.
You'll know for sure in a week or two. The next time you fill up.
good luck
