brus brother Posted May 15, 2005 Share Posted May 15, 2005 How often is it suggested (or safe) that you use Seafoam for top engine cleaning. After 5 years running with timing 1 tooth off (no cel or code) I wonder if I am still suffering from carbon buildup after one treatment (still pinging with 89 octane, 87 suggested). Will it do any harm to retreat again after only 2 days? Quote Link to comment Share on other sites More sharing options...
Olnick Posted May 16, 2005 Share Posted May 16, 2005 Never retreat, Brus. Always try to move forward. How much have you driven since you ran the Seafoam? Actually I don't think it would do any harm--kinda' like a super heavy dose. Maybe that's what you need after 5 years. Wouldn't get in the once-a-day habit though. Any other opinions?
