MPG Question
 

1995 Ford Mustang GT 5.0

I had an oil pan leak, gasket was trashed and I believe oil is leaking inside the Engine, just not a lot or anything.
I just replaced the Oil Pan Gasket (new one is way nicer/better), 10w 30 Royal Purple and K&N Oil Filter.

First full tank on the new stuff. 162 (I think 161.5 to be exact) Miles at 13.376 Gallons, most of that was city except like 20 miles of highway roughly. Usually it's way lower.
I do have a led foot for the most part. My thing isn't burning out, sometimes I do, but since I got new tires I haven't really been doing that at all. I'd be more of going fast and loudness.

With all being said, would this be a normal MPG for me?
I was thinking of getting a tune to hopefully get better gas mpg, but not completely sure about it now. Sorry you probably can't understand my stupid language.

Well, first thing I'd do is fill up completely and try calculating your mpg while staying real light on the gas. Accelerate slowly for a day or two and post back your results. If it's still around the same mpg then you've probably got a bit of problem.
