yeah, i'm running seafoam in my oil right now, and i've noticed that it's leaking a little bit more now than it did...

i know a lot of people are going to say no way in hell .But a old man I knew took every oil change drained the oil put the plug back in put in 4 gt of del fuel and started it ran at idle for 5 min drained it and replaced the filter. I helped him rebild the motor it had 396,000 on it was 67 307 chevy .And I can say one thing it looked like it had been run on LP gas sence new it was so clean inside all we did was dip the parts in gas to clean them off.He did the same thing to a 79 Ford truck with 302 he sold it with over 300,000 on it and still run like a top.One thing I noticed when he changed the oil it took about 2,000 miles before it got dark even. I have done this to my jeep a fu times and to other car and trucks it works for me .
