Update on my update of 93 240 that failed the emissions test in Ontario

I used a second bottle of that "ultra fuel treament" and
responsiveness of the engine has markedly improved.

I said earlier that I was to run a third bottle right before I do my
next oil change, but I decided not to. The car has improved so much,
I passed the test after the first bottle and I decided to use a second
treatment to see it there would be any improvement.

I do not want to push my luck. If I fail the test in two years, then
I'll give it another bottle.

BTW, here in Ontario the test is valid for a period of 12 months. So
what I do is take the test 11 months and 3 weeks earlier. Instead of
taking the test right before my birthday, I take it right after my
birthday, but almost a year ahead of time. This gives me almost a
year to fix anything that needs to be fix. I suggest you do the same.
