A Few 5.0 questions Reply #1 – September 04, 2014, 09:25:59 PM Check your timing. Most fuel additives are just alcohol and a bit of atf. The only reason mpg would be higher would be if you have spark or timing issues. My bone stock 193k cougar gets 20mpg all day long delivering pizza and 25 to 28mpg at freeway speeds.VEry few cars benefit from "better" spark plugs. Throw some $1.99 autolights in it and call it a day. Quote Selected

A Few 5.0 questions Reply #3 – September 08, 2014, 10:47:51 AM Low mileage axle dampers will not work from a Mustang if the OP is referring to the rear shocks which is what I was reading but maybe not. KYB's are really good replacements for the struts and shocks and do not cost an arm and a leg.Darren Quote Selected
