Can Spark Plugs Last 100,000 Miles?
There have been times when the technicians at Danco Transmission & Auto Care have found spark plugs seized in the cylinder heads of some of our Fairfield area customers' vehicles with as little as 60,000 miles on them. The removal of these seized plugs can result in hours of labor by our technicians at Danco Transmission & Auto Care. There have been rare occasions when Danco Transmission & Auto Care has needed to remove cylinder heads just to get the spark plugs removed. Danco Transmission & Auto Care suggests that in order for our customers in the Fairfield are to maintain peak performance for their vehicles, that their spark plugs should not be run longer than 30,000 miles. Danco Transmission & Auto Care suggest that consumers should take those 100,000 mile spark plug marketing claims of manufacturers with a grain of salt.
