I thought about pouring some seafoam into the oil a few days before an oil change. Does anybody foresee any problems this might pose? This would be in a classic. I've been told it can cause a lot of sludge to clog the oil pump. With 79,xxx miles, how much sludge could there be?
There should be no sludge if you keep your oil changed and don't use Penzoil. Seafoam makes your oil thinner, I would not want to drive too much with your oil like that, if you want to add it before, do it 5 minutes before the oil change and keep in mind some oil remains, and so will some Seafoam. I stay away from Seafoam, I don't like it, that's my opinion.
I used it in my oil once but I did it as Randy states, the day of the oil change I ran a few errands with it in there, I also did the vacuum line and gas tank. Seafoam can work some wonders, got rid of a carbon problem my brother had on his Chrysler which in turn helped him pass the emissions test. Just be carefull adding to the vacuum system, I had it back fire and puff out smoke on me haha.

I have been using Lucas as an additive for years. My 98 Aurora had almost 200k oil pressure at idle is 12-15psi w/o and 19-20 with. You make the call. Had over 350k on my 93 Cultass. I also started changing the oil at longer intervals. With no more than a pound or two difference in pressure
