The only real way is to send off the oil for analysis

Detergent oil --or non detergent

Thermostat??

how rich do you keep your mixture

short trips driving slow?? or do you drive long enough to get the oil hot??

If you are using detergent oil, run a thermostat ,are getting 18+ mpg and drive more than 25 miles at highway speeds 1 out of 4 drives I would think 2-3000 miles or 1 time a year

If you use non detergent oil, don't have a thermostat, only drive 1 mile trips, get 8 mpg, and keep changing to hotter plugs to get rid of the black fluffies 500 miles may still be a good time
