RE: Time to change my oil
It's your motor. Petro-based oils, especially Pennzoil, are loaded with parafin, which builds up in the motor.
And do the math. An $8 quart of synthetic oil that lasts 25,000 miles is cheaperin the long run (because it lasts longer than 6 regular oil changes) than a petroleum-based oil that would get changed every 3,000 miles. It works out to $1.33 a quart/mile, or whatever the ratio would be called.

jesus.. never did the math.. but thanks for that.. isnt quaker and Castrol both synthetic or have good quality synthetics.. since they are advertised on SPEED all the time and the sponsor almost every racing event i watch,i figured they have to be pretty damn good
