I don't think EO cleaning/detergency additive(s) work this way. It is a NOT quick fix that most people hope for.

Just sharing that I used CI/CI+ HDEOs in my 21yrs old engine to flush/clean grime accumulated over the years. And for sure it wasn't a 15-30mins drive-it-on-highway job. It needed over 4-5 oil changes to see the effect. And it won't be squeaky clean like day 1. I stopped using HDEO for the time being coz can find other budget EO online that give value for money.

FS EO can do too, but I don't think the super cheap FS that you can find online will work. FS PCMO that I know will work is SHU and Mobil 1 0W-40, coz these were proven to clean when I got them cheap. Again, they don't work as fast as most will want to see, like in 30mins.

Good information. The EO flushing method like I said drive for 1 week at least then flush out the oil and see the condition. Also some highway runs too if possible. Or drive like normal if your daily drive have highways. This will allow you to see the engine condition without taking out the cover. Repeat as needed. If the engine oil is dirty then change oil more often until you are satisfied with the result. By that time, if all is good, back to normal oil changing interval. When it already have lots of carbon build-up, normal interval with good quality oil will not help already. Need it change oil more often. Unless you want to try Royal Purple oil.
