I don't take anything from Scotty Kilmer as truth. Maybe checkout the Project Farm videos.

There's an oil chemist on YouTube by the name of Lake Speed Jr, has a channel called the Motor Oil Geek. He covers oil and oil additives mostly, but also will discuss filters and fuel as well. Long story short, he thinks fuel cleaner additives are probably good every so often, if you're not using top tier fuel (or you have a diesel). But with oil additives, sometimes adding things to the oil can negatively impact the lubricating, cleaning, or anti-friction properties of the additives in the oil already.

The general consensus seems to be it's best to use a quality synthetic motor oil that will clean your engine over the course of a few oil changes, rather than trying to do a motor flush, or adding something that may interfere with an oil's natural properties/additives.

This is probably reasonable to add to fuel, or metering into the upper cylinder via a vacuum line to try and clean the backs of valves. But it doesn't have PEA in it, which is considered the best cleaner by many. The cleaner in sea foam is something that was good many decades ago, and I'm not sure it has been updated.

7.50 at my store, which is weird because I bought 6 cans last month on clearance for 6.20 each at the same store. 😆

Use by directions and it works. Add about 100 miles before you change your oil (1oz per qt) to get rid of sludge, i put the rest in the gas tank to help clean fuel system.

Quote from MadPup :
People have tested these types of additives and their effectiveness is marginal at best. It's also best to not add anything to your oil since it can negatively impact the oil's performance. Just buy a good oil. Valvoline Restore and Protect seems to be flavor of the month.
Not true. Used in oil for a limited time, these are fantastic at breaking down carbon deposits.

In gas tank, depends - smaller tanks will benefit more. If you dilute this in a 93 Ford Bronco with at 30+ gallon tank it's not going to do much.

This carector "Scotty Kilmer" is one most annoying character on YouTube. I always click " don't recommend this channel" we he gets on YT feed.

At my store, they were located in the tool section with the other automotive products.
