Tried something new this week ... had 30 miles on it from driving around town, and decided NOT to top it off Sunday night. Figured I've been seeing around 50 MI to E when filling up each week, why can't I do this extra driving at the begining of the tank ??
Filled up today ... 442.4 miles / 14.798 gal = 29.90 MPG.
At the time of fill up, computer was showing "4-MI to E" and "28.6 AVE MPG".
Total miles on car to date is 5134.8.
There was some pretty heavy rain Monday morning and had MAX-AC on most of the week (hot & muggy high 80's to mid 90's), so this was not too bad.
O/A ave. MPG since new is 28.73 ... but O/A ave. since I 1st broke 30 MPG 3100 miles ago is 30.20 MPG.
I'm real happy with these results.
As I've broke 5000 miles, I'm going to do my 2nd oil change this weekend and switching over to Mobil 1 Full-Syn. Did 1st change @ 1500 mi w/ factory Motorcraft Syn-Blend back in.
