Can you compare the engine treatment 505 products to Kreen by Kano? If you have not tested Kreen from Kano, then I would recommend this to you. Especially the plug, oil, fuel restore treatment
You know the best way to clean pistons? Italian tune up.
If it's not misfiring or anything wrong with your engine, leave it alone.
If you would like to contact Scotty directly to suggest he make such a video see the FAQ for instructions on contacting him.
Thank you for your suggestion. I will review the FAQ. I would like to know users experiences with these products. Especially the 505 in comparison to the Kreen.
I saw FAQ at one point but can't seem to locate it. As well, the search tool at the top doesn't show results for generic terms such as "oil". What am I not doing correctly in the search tool to get info from from posts on a topic
Gasoline is the best cleaner. You do not need to do anything if there is no issue.

Got an old toyota burning oil theres probably sludge in the piston holes. Read in a forum i could soak the pistons and it will go away....sooo scotty doesnt answer questions on here anymore? Shame i wanted some knowledgable advice on kreen
Scotty does answer questions here and even answers some in his videos but he cannot possibly answer all of them.
