I swear by Seafoam. It has really helped out my small engines, especially the 2 strokes and ones that sit around for long periods of time like my leaf blower and roto tiller. After I started adding Seafoam every time I get fuel I have had zero starting issues. They can sit all year and they will still start right up. In my car/trucks with higher miles I've used it to clean out the crankcase with great results. I add a can to the oil right before doing an oil change. I add a can then take a short drive(10 miles) to make sure the oil is up to operating temperature and change the oil once I get home. It does a good job cleaning any sludge out of the pan and the new oil stays looking fresh/clean way longer.

It's Sea Foam (but not green)

Color: 3 Pack

What is there to say? If you're buying Sea Foam, you know what it is and what it does, and you're probably going to continue buying it. It's great stuff.
