I was wondering, is it safe to NOS (only a 50 shot) on a high miled motor (150,000+)???
The motor seems to run strong, and i get more than decent gas mileage (25+). But i really don't wanna damage the motor.

Also i was wondering what are the signs of low compression or running in lean conditions??? Also i was wondering if there are any simple ways to check if you are running rich or lean w/o NOS, or any simple signs of having low compression in your cylinders.

please i need help..
thank you
