How long can I run the Cabie on low test?

would this work???
 

or does the cost canel out the savings<ul><li><a href="http://www.fppf.com/prdOctaneB01.html">hmmmmm.</a></li></ul>

When I start pinging I'll try it

She's not going to like you very much if you do, I would alternate fill-ups
 

Low then high if you can.

That's what knock sensors are for.....
 

Sister runs 87 in her '98 all the time, and I only ever run 87 in the 5kq. The knock sensing equipment does work, you'll loose a little performance, but in normal driving you won't notice.

Forever, as long as you use this...................
 

I have run 9,000 miles on 87 with the Fitch.
No knocks. Runs fine.<ul><li><a href="http://www.fitchfuelcatalyst.com/">http://www.fitchfuelcatalyst.com/</a</li></ul>
