For a long time there has been a solution to cleaning your engine and that is SeaFoam. Per the company SeaFoam is 100% safe when used as directed. You dont need specialized Valvoline oil or Mobil Advanced Clean. All you need is a quick visit to Home Depot to grab SeaFoam and a measuring cup.

Im sure the Valvoline Restore and Protect works but Im also sure SeaFoam works as well.

Seafoam is expensive for what it is. Oil, alcohol and some naptha. How long do you think it really stays in the oil before the naptha and alcohol boil off? The you just left with the base oil, diluting the ad-pack of your existing oil.

I also don't think the answer to alcohol fuels, is more alcohol. Which is what you are adding with seafoam.

EDIT: I just looked at the SDS i don't see naptha listed anymore, but could be part of the listed hydrocarbon blend. Isopropyl alcohol is listed on the SDS as <25% Hydrocarbon blend <95%

I did have some luck with seafoam smoothing out the idle on my 1976 Johnson 9.9. After 40 years of 30w, then TCW and TCW2 I imagine it had some carbon build up and the carb was a bit dirty. Ran it in the gas and sprayed it in the carb and chocked on the smoke but it came out the other end running better. I however would never put it in a modern engine.
 
The only thing I use Seafoam for is for GDI cleaning up top. It seems to help with some carbon prone engines if sprayed in the intake of a running engine.

I wouldn’t add it to fuel or oil.
 
Sure hope you’re not adding that to your AMSOIL Signature Series….

Don’t forget Marvel, Rislone, STP, Motor Medic, Militec, Motor Honey, ATF, diesel fuel, Badger Juice and all the others.
If all the various videos and threads are correct you wont need to add anything to Amsoil. Two notable Youtube videos had OCIs of 5000 and 10000 miles with Amsoil where the engines appeared clean when opened. The Ford Tech stated the Ecoboost engine with 5k OCI at 80k miles was the cleanest he ever seen.

The "Bearded Ford Tech" on Youtube had a Ford Transit van with 10k OCI at around 80k miles...1st gen 3.5 Ecoboost. The engine appeared clean with only slight hints of varnish in tight places. In another video he reveals a huge 55 gallon drum of AMSOIL Signature Series 5w30 he states he uses for everything.
 
I have never heard of Seafoam doing any good to any problem. Never would I pollute my crankcase with it.
Amazon, Walmart and Home Depot reviews...tens of thousand total reviews...rate Seafoam at 4.8 out of 5 stars (Home Depot is at 4.9 out of 5 stars). Various youtube videos demonstrate cleaner and better running engines. The company states the staff in their office use it in the oil of their GM 5.3l SUVs with no issues. I looked at all the reviews and videos and nowhere do I find anyone with apparent engine damage.

Are the folks who put together the Youtube videos and tens of thousands of reviews misguided? Will the office staff at Seafoam be replacing their engines in the future? If you read these reviews and watch.the videos will you go back on your statement that you never heard of any good being done by Seafoam?

"tens of thousands of total reviews" ... by people who have no idea how to judge something objectively, never established a baseline for the conditions in which they use the Seafoam, nor use a control group for comparison/contrast, or have access to calibrated lab equipment which can verify or deny the basis of any improvement claim. These "tens of thousands" use subjective criteria coupled with a large dollop of placebo effect to justify their findings/results. They are often found watching PF vids because they think that's "science". And the results they brag about are anecdotal at best.

It's hard to find "apparent engine damage" when one is blinded by marketing hype and rhetoric. That does not assure anyone that Seafoam is detrimental to an engine, but it does not address the lack of looking objectively for any damage, either.

I'm not one to claim Seafoam is junk. But I've got much better things to spend my money on, because the ROI isn't nearly as good as many perceive.

I know. I’m asking why you would ever add this garbage to your AMSOIL Signature Series?
