If you have to ask strangers on a Forum then it would be best to use a product you know and trust to start with . I seriously doubt SMB would put something out that would harm your engine .
If I remember correctly, you are Firestone customer for somethings, they carry a Renu 500 that goes in the fuel tank, it is also part of the FST (fuel system cleaning) that we discussed in a prior thread you started… It is a commercial product and not available at auto parts stores…
Or just buy a bottle of Seafoam and be done with it…

I use only Top Tier gas, but I also add a bottle of Techron to the tank once or twice a year, just to be on the safe side. Techron and Seafoam are the only fuel system cleaners that I will use.
I’ve never used that brand so can’t speak to how well it works or if is has any adverse effects. Ray usually recommended Techron to the callers on his show. But he said his shop used a specialty product who’s name escapes me, and he said he got the best results from that. I’ve used Techron and a specialty brand only available in the SF Bay area, not b/c of any symptoms but seems to help the car pass the Calif emissions testing limits.
Why are you thinking of using this product? Emissions testing? Symptoms? I wouldn’t recommending using fuel injector cleaner proactively, with no symptoms. I think the best bang for the buck is using a name-brand gasoline and keeping the fuel filter changed on schedule.
In 1988 I had an injector sticking. The dealer used their cleaning kit and that solved it. Never had an injector problem since and never use an additive except with the diesel in the winter to prevent gelling. I do recall the mechanic pointing to a vette in the next stall saying it needed three new injectors. I suspect things have improved over the years but still have found no need.
If you read the label, which you did, you see that the ingredients are much like paint thinner and carburetor cleaner. Any brand will do about the same thing. I recommend one can a year and I used to use it when I went on a long trip.
I guess you can tell that I went back to read the label and didn’t see a list of chemicals. I bet it doesn’t matter that much but I did read a can of Sea Foam once.
I only see methanol and proprietary ingredients. Am I missing something? Anyway, I’d get the Safety Data Sheet (SDS) for the product and similar products from Seafoam and Techron. Compare the ingredients to see how similar they are. The manufacturers are required to disclose all toxic chemicals in the solvent, but not the exact percentage. There will be a range of percentages listed. Note that methanol will damage your fuel system if it is in there for too long and in high enough concentration. Don’t use too much (i.e. if one can is recommended don’t use two).
I remember some fuel filters under the hood of fuel injected cars. The solid metal ones were hard to remove without damaging the tubing. The ones under the car were difficult too.
I used to like seeing the debris in the clear filters. I had a 65 Fairlane with the one that looked like an oil filter. Unscrew it and change the pleated element. 2002 GMC Sierra had a filter on the frame rail. “We’ll have to get a kit for that one”. A fuel line repair kit was always needed for my 65,000 mile maintenance style.
