Definetly change the oil right after that! I forgot to mention that earlier. The main thing about the seafoam in the engine is that itloosens it up, then when the engine starts and runs it breaks it up and spits it out. That is all that I have heard about the stuff, I have used it in the past (even pooring it in till it dies!) and it has worked great!

 

I agree it is a very good product.

 

We did a B&G treatment at the garage I used to work at. We would IV drip this B&G stuff into the vacuum line while the engine was set at 1500 rpms. The B&G guy said it has to be dripped or you can cause damage to the engine. When it drips the engine draws it in and it turns into a vapor before it hits the engine. (They showed us a demo of how it works on their work van using a clear hose on the brake booster). So I agree that small amounts of Sea Foam would be better than pouring it in. The B&G guy also stated that for maximum results to choose a vacuum line closest to the center of the engine as some brake booster vacuum lines are off to one side or the other. Changing the oil was not required but recommended. The biggest downfall to this treatment is that it took 15 minutes to do (minimum) and at 1500 rpms you killed a good amount of gas in the process.
