Question about in what order I should add Seafoam

[wfls]

I just bought a can of Seafoam, a Wix oil filter, and ten quarts of Napa 10W-30 for my 1990 Nissan Hardbody w/ KA24E. I want to use the Seafoam to clean some sticky lifters in my engine, change the oil, and the oil filter. But, I don't know what the best order is to perform these services.

My first thought was that I don't want the Seafoam to be in my crankcase long term, and I don't know what kind of damage it might do the new oil filter. So, I thought I should drain the existing oil, add new oil, and add Seafoam. Then, a thousand miles later, drain the oil & Seafoam, change the filter, and add new (higher-quality) oil.

Does this make sense? Or am I just wasting time (and oil) with this extra step? Should I just replace the filter and oil now, add Seafoam and leave it be? Would this have any long-term effects on the filter or the engine?

Thanks

How many miles on your current oil? I would say add the Seafoam now and then change it 3k later. I think the seafoam is pretty light stuff and will flash off rather quickly

What does seafoam do? I just can't get past the ingredients. ARx at least has magic esters.

Change the oil.
Then add seafoam - NEVER.

I don't want anything with a fair percentage (~20%) of 2-propanol on its MSDS ingredients list in the oil sump!.

If you insist on using seafoam then add it to the sump, idle for ten minutes then drain, replace filter and fill up with oil.

My engine has 190k+ miles on it. The odometer is broken, so it could be much higher. I should add that the filter needs to be replaced pretty soon, as it has been on there for more than a year.

What is the concern with Seafoam? Is there a better additive for cleaning the lifters? On other auto forums I know most people swear by either Seaform or Marvel Mystery Oil.

Yeah, there is still a lot of folks who swear by Lucas Oil Stabilizer, though they have no idea what it is made of or what it does.
