Home made Seafoam?

[Way Amigo]

Just wondering if anyone has tried this?

This is an interesting experiment. I think I like it. It harkens back to my teen years when an old mechanic said;

"Get 'er hot & drain the oil if you get black nasty oil then fill 'er up with diesel to the full mark & let 'er idle for 5-10min. Then drain it again, pull the filter & put new filter & oil in"

I have done this, on 4cyls & big block v8's, it works really well & seems to have no ill effect (just don't drive on diesel, not enough viscosity to handle any load or rev'ing). Never thought of doing it to trans / T-case / diffs though, probably work similarly... Get it hot, drain it, fill it with diesel/naptha or whatever, crawl around the block or up/down your road idling through the gears (for sticks) & then drain & refill with good stuff.

Nice find

This recipe is not Sea Foam exactly, but it is similar.

How does he know? There are numerous different types of naphtha besides VM&P, which happens to be the cheapest and only one available at Lowe's.

I know some people that own dirt drag trucks. They also run a cabinet shop, and finish their cabinets with lacquer. They came up with a "racing fuel" that consisted of Xylene, Toluene, High Flash Naphtha, and lacquer thinner (that consists of the same three products plus a few others) and mix with some particular amount of gasoline. They swear by it.

When I was younger, people would mix moth balls with premium gas. Other people would mix a gas additive called "Wynn's Spit Fire" with Amoco Premium. (Amoco premium was lead free years before the government required gas to be "unleaded")

My point being: Did or does any of these contoctions work? I don't know...and they didn't/don't know.

Seafoam is $7 at Walmart. When I need some, I will get the real thing.

Everyone I know uses the diesel method you described.

This is a good point although I'm sure the folks using the racing fuel must have had some idea.

It would be nice if the site posted a followup showing results comparing the cleaning action of both.

I've heard of people doing the change at the top of a long mountain road, letting it coast all the way down and then drain it and put the oil in.
