Seafoam--can't believe what it did to my engine part 3--cylinder cleaning test!!

I've been watching your videos for quite some time now. I've been able to determine what products are best for me and the job I'm doing based on your data. I appreciate all the hardwork and effort you put into these videos. I'll continue to watch your channel for as long as you'll make videos. Thank you very much for your time and elbow grease

After watching your sea-foam videos, I finally did the same treatment to my outboard marine engine. Thanks a bunch! My engine used to stall a lot. But now, an entire month has gone by and no stalls. Also, I noticed less vibration.

How about a long term treatment. Run the seafoam in the fuel all summer long, then before you winterize for the end of the season pull the head and see if there is any change.

I expected more of a difference overall. However the biggest change seemed to be around the valves. I would guess this is why folks often experience an improvement in engine performance and compression. Great video! Thanks for posting.

I salute to people like you that make YouTube great, I really hate those senseless vlogs of people who just share where they went what they ate what they shit like. You are an amazing man, you make us learn a lot new stuff. hats off.

Thanks for your time producing that video. I've used SF for years...ha, I always pictured the internals as "chrome-like" when I was done....not what I was really expecting. Ya gotta give a high-five to those marketing people. Thanks again

I was expecting it to be much cleaner, but I can see the difference. I was probably expecting too much having seen the results on your previous video. It is certainly a product that I am considering using on a couple of our cars and some garden equipment. Thank you for the videos.

excellent results, I couldn't believe the difference after only one application. I'm glad that you produced a real before and after video on the product.

I don't think it made much of a difference.

You really deserve more subscribers, you make much better content than all that clickbait out there. You're straight to the point and very organized. Thank you for what you do, I will always watch your videos as long as you're making them, I've learned a lot from your videos.

i think your mower has a bad power steering pump

I was really sceptical of SeaFoam, too, but after several cases of having small engines stop running because of carbon buildup on the intake vales and running SeaFoam through them after cleaning the intake valve enough to get them restarted and checking the engine again, I'm a Sea Foam advocate! The LUCAS stuff is really great, too! I used it on my old '90 F-150, 302 and it runs like new. I used both Sea Foam and LUCAS Injector Cleaner as an Intake System Cleaner. The engine no longer stalls after startup and runs awesome. I did the LUCAS/Sea Foam treatment over 5 years ago and will do it again this summer as a preventive measure! Thanks for the great video!

Every time I have wondered about a product for my gas vehicle or when I bought my diesel you have been there with a video. And even my multi tool bits. Thanks for helping me so much you always provide very reliable information.

I am a California SMOG Tech and I use Seafoam all the time. It really helps cars that are failing for NOx emissions by cleaning out all that carbon. My customers notice the difference right away when they drive the car and I have seen it reduce NOx emissions by up to 1000ppm. I use the vacuum method and tell the customer to put a can in the fuel tank too.

Going back to these old videos is great. So glad to see what this channel has become. You deserve all your success.

I ain't never seen a mechanic work as fast with a ratchet as you!!!!!!!!!!!! Amazing!!!!!!!!!

It didn't make as much of a difference as I thought it would, but I'm sure it helped. Thanks for the video series!

You earned a sub. It's a pleasure to watch you work, and present non-biased results.

Man, watching this video compared to 2020 videos. You’ve polished your videos up really well.

This is one of the best made, well thought out videos I have ever seen. Well done.
