Can
I Save Money and Run Low Octane? Wrong!
Here is a dyno chart showing two different
cars. When I dynoed one of these cars, I knew that something was
immediately wrong! Guess which one?
Notice that the 89 Octane car's power curves
are very jagged. This is a result of the car "hearing"
knocking and pinging and desperately trying to adjust the timing and
save the engine. The ECU is almost searching for the best advance
and having quite some trouble, not good.
The stunning results of running the lower
grade fuel are -22 ft/lbs and almost -19 HP!!!! Ouch!
Folks, don't abuse the knock sensing
capabilities of you beloved car. Let's just stick to the good
stuff!
