Car: 95 Legacy Wagon AWD 5sp
I switched to 10% ethanol blended "regular unleaded" a month ago and could swear I'm burning about 2 litres/100km more that I used to (city driving). I think ethanol bends are suppose to burn a little cooler and have higher equivalent octane rating. Could the ECU be running the engine rich because of this?
I'm about to embark on a 900km drive (all highway) and am wondering if I need to do something simple like reset the ECU before hand?
I switched because it is suppose to burn cleaner, but if the ECU is running the car rich all the time, that can't be good...I'd be better off running regular fuel (not to mention saving 1$/100km).
(or is this all my imagination and I should try it for a little more than 1 month!)
cheers!
