Re: 1990 V8 Fuel Injection issue

by "Bill Mote" <bandjrest@[EMAIL PROTECTED] > Feb 28, 2008 at 04:23 AM

I run Techron about every 10th tank or so. I should add that this issue 
occurred very suddenly, and is also intermittent. I can be driving at 70
mph 
show 12 - 14 mpg on the level and then suddenly the mileage jumps up to 
21 -22 mpg.  Overall average for the past 200 miles has been in the 11 -
12 
mpg range, prior to that it was always in the 21 - 24 mpg  avg. for
freeway 
speeds.
