When I added the HPS tube it went up to 23.7 MPG |
I averaged 25.6 on my second tank of gas and that was around town, highway, stop and go traffic, etc. It's very possible to get these cars to get good mileage. Add in some AMSoil SSO 0-30 and free flowing exhaust, intake, etc and 2 mpg should be the very minimum gains you see.
