I just finished with the seafoam cleaning in my new ride. When I purchased the car the previous owner told me how mch he took care of this car. I was so impressed with some of the things he said I figured I wouldn't have to do anything for a long time. So I just changed my oil and filter, and while I was under the car i figured I would check out the fuel filter. Bam he was full of $hit. It was the very one from the factory. So another trip to the auto parts store. When I removed the filter it looked like a river in a foreign country. Also the air filter looked very original at 77k. WTF Dont people understand normal maintenence. Anyway waiting 3 days for a new air filter, but new filter, seafoam, and synthetic oil change the car woke up.
