I also have neutral coasting rpm at like 1900rpm. I have to coast really fast to get the scangauge above 100mpg.
With my Zetec 2 L auto 03...I rarely see a fuel cut. RPMs when coasting with my auto are usually pretty low...about the same as resting idle warm.
I'm going to try the copper plugs and change them out 1x per yr.......currently running Autolite double plats
"Copper - short life, best performance (and mileage)
Platinum - long life, worst performance
Iridium - long life, performance between copper and platinum (hence their pricetag)"
The "Correct" Acetone for Automotive Fuel Testing - Gas Savers - Fuel Efficiency Forum
There is 100% Acetone and then there's C.P. 100% Acetone
The usual stuff has a additive, however small in molecular terms that makes it unusable for making C4 or whatever boom stuff the commies and others make for illegal purposes..
And YES, using it with Ethanol poisoned fuel, does have a minimal effect, using it on Alcohol free gasoline does have some positive effects.
2 of us old wrenches, [over 55] that are technically astute and have tools such as a/f ratio meters for carb'd vehicles,, have noticed some positive effects.
On older GM units, 92 4.3, 96 4.3, 2000 2.2L all exhibited the same effect using alcohol contaminated fuels.
More Power in High Gear w/Torque Converter Locked
Better Hill pulling power at partial throttle
Minimal Economy increase, we were not scientific enough to post, but a little gain.
There was NO obvious Improvement at WOT in any vehicle.
We did No GPS or electronic devices to monitor.
On a old 25hp Mercury Outboard, it started easier, idled with much less shake in the throttle handle..
We NOW have Alcohol Free fuel available locally and plan to do some lengthy testing. I.E. ONE tank of fuel is not a test. Several tanks "averaged" out is ..
A positive point is the acetone did clean the injectors on each unit also on my Ford 2600 Gasoline Tractor it cleaned the carb so I don't have to run the choke full time anymore.
The Mixtures we used;
a small amount of synthetic 2-cycle oil, enough to "color" the mix
Ditto on the two cycle oil
In a one gallon container, we'd use about 1-tsp of 2-stroke oil.
I'm currently using 3 oz / 10 G at a 50/50 mix acetone/xylol with some 2 cycle oil.
