I've used it in mine didn't make a difference I only run 91. it smoked a little and this was when I had about 105k on it. I did it in my 06 envoy with 45k and it smoked out my block when I took off.. We only run the cheap shell 86-87 lmao I only use 91 so I forgot what the other two octane's are

Saw this one a long time ago on LT1engine.com:

Long-winded but explains what he's doing, in what order, and why. FWIW/YMMV

one full can in the vaccum line from the booster to the manifold, on full can in the gas tank and one full can in the crank case no more than 100 miles away from an oil change. i do this about even 12k miles. before i rebuilt the motor i did it often and when i tore it down it looked brand new.

i have a 94z28 i bought it with a blown engine, i found a replacement engine that had been sitting for a while..
after i got the replacement engine installed i seafoamed it, basicly didnt know what oil the previous engine owner used and i wanted to clean it somewhat internally before i put in synthetic.. i've used a pint of diesel fuel to do the same thing on older engines.

I have seafoamed lots of cars. And stopped doing so after a couple Ks after the cleaning. I have found it fouls plugs shortly after treatment and a lot of cars I have done have started having slightly irractic idles when cold started. I wont seafoam a car ever again. Except maybe run it through the gas tank.

everyone has heard of the "miracle" engine repair stories from seafoam, but I've never seen anything too amazing...chances are, if you're having engine problems, the solution to the problem usually doesn't come in a bottle...some of my buddys put it in their gas tanks over winter tho...

Right. It can be depending on how it's driven. If an individual drives like old people ****, never taking it past a certain rpm, driving short distances or predominately in stop/go traffic then it can be a prollem.

I pulled the valve covers on my car about a month ago for the first time since I bought it. A lot of gunk built up under there. I put the half-can of seafoam in the oil and drove it for 100 miles non-stop. Changed the oil and did find lots of little b-b sized chunks of sludge, but pulled the valve covers and couldn't tell much difference there. Car runs great before and after the sea foam, just using the stuff to see if it would clean out that sludge left by the previous owner. When I bought the car, the oil was like syrup when it drained out.
