My Mazda-Toyota service advisor recommends a MotorVac CarbonClean Service at 45,000 and 75,000 miles. I'm located in Lancaster, PA. and drive a mix of highway and city driving to the tune of 15,000 miles per year. I have both our families 2000 Mazda Protégé ES's serviced every 5,000 miles at this dealership. Their suggested service schedule is more aggressive/costly then my manufacture's recommended service schedule. However, I'm not against profit for the service department and have loyally adhered to their schedule. In return, they have handled several warranty issues quickly and with excellent workmanship. I also believe they were able to get couple of minor issues covered under warranty when perhaps they were pretty boderline. They have also repaired some minor things for no charge and treat me as a valued customer. I would rate this service department a 9 out of 10. Nonetheless, they claim the MotorVac system connects to your car's engine and circulates a mixture of MotorVac solution and fuel through all fuel system components. This cleaning solution removes carbon, gum and varnish from your engine-from intake to exhaust. A MotorVac CarbonClean Fuel System service:
*Restores "new car" performance
*Restores fuel economy and helps the environment by lowering your car's emission.
I don't know if it's worth the $75.00??? Sounds too much like a late night infomercial to me. What do the regulars at the Maintenance & Repair topics think? If it has some value to a good regular preventative maintenance program I'll consider it. What say ye....
