STP Super Concentrated High Mileage Engine Flush

It's been out for a while, but availability has been spotty.
Used it in a sludger. Basic 15min idle flush. As effective as Liqui-Moly engine flush. Meaning you won't see any cleaning visually, but it may clean the oil passages and hydraulic lifters a little. Which in turn sometimes improves oil pressure or quiets down a noisy valvetrain.
Product has it's place, but I achieve same results with MMO, which is $4.12+tax near me for 32oz. And I like that MMO can be driven with. Offsetting low 5W viscosity of MMO with a one-step higher viscosity of motor oil is a good idea, although not required. Just a "safety cushion". (Example: if 5w30 is recommended, use 5w40/10w40 with MMO in 1:5 ratio.)

I prefer the Liqui Moly flush as the engine needs to be at full operating temp.
Heat will break down carbon and sludge better than cold.

I have ran the liqui for 30min using new 5w30 engine oil on a dirty engine before. Great results.

What specifically were the great results?
 
I used the STP synthetic engine flush in the gold bottle. I don’t think it did anything. The engine oil came out same light brown color as it went in with additive. It’s a 190k Lexus v6 and I saw dark “stains” in the oil fill hole which led me to use it. I bought this one since it’s $7 not $18 like liquid moly.

YouTube videos had me hoping for a darker oil drain like the LM engine flush videos. Maybe my engine is super clean inside… or the STP didn’t do sh!t
