THIS would be a very logical explanation as to why you had carbon on your rear valance. And then why it went away. And it also follows my theory of a rich condition, which revealed itself to you in TWO very prominent ways here:
1. Carbon on the rear bumper from an overly-rich fuel mixture
2. Gasoline in your oil from an overly-rich fuel mixture
This would definitely affect your vehicle's fuel mileage.
Wow! the bashing of Amsoil never stops!
the guy spends time and money with us here and a select few posters here attack the guys credibility.
Well let me throw in my .02 here...
lets hit on the carbon on the rear bumper.
I would say the fact that the carbon on his rear bumper stopped, is for one reason.
I would say that the 3000 mile run that burnt up a quart of oil was left on the back of a civic. simple as that. piston ring packs is where oil does its job or lack of.
I say the Amsoil holds up to 450F temps much, much, longer than dino oil that cakes up and goes out the tailpipie!!!
I love to hear that somebody using the best is getting his money worth in fuel milage alone
LOL LOL LOL!!!
I believe the guy and his 45 mpg civic
Bashing of Amsoil? I'm sorry, but please show me where I am bashing Amsoil? In fact, I'm running Amsoil in my dad's Expedition right now, and have run it for a number of years in Diesel lawn tractors.
I have had great luck with their grease, oil, gear lube...etc.
I simply refuse to believe it can cause a 7 Mpg increase in fuel mileage. Especially when an obvious rich condition, which the OP later rectified with the replacement of the FPR and was documented in this very thread is there as a quite plausible explanation!!!!
