tmise40 Posted September 20, 2022 Report Share Posted September 20, 2022 Considering buying one of these to give my system a GOOD cleaning to help with bad gas mileage. Only getting 16.8 mpg city/highway. When I fill up the info on dash panel states a full tank is getting me about 20 miles less per tank full. Wondering if anyone has used this type of cleaning system that uses an air compressor. Is there one you would recommend that won’t break the bank? Also will change the oxygen sensors to see if that helps. This is in regards to a 2009 Ford Edge Limited 3.5 with 158,000 miles. Thank you!
