The STP Super Concentrated High Mileage Engine Flush has garnered positive attention from customers who appreciate its effectiveness and value. Many users have reported substantial improvements in their engine performance after using the flush, noting that it successfully loosens sludge and grime accumulated over years of use. Customers with older vehicles, like a 1986 Chevy C10 and a 2003 model, have highlighted its ability to significantly clean and rejuvenate the engine before an oil change. The feedback indicates that this engine flush is particularly beneficial for those who may not keep up with regular oil changes or who drive high-mileage cars. Users have praised its ease of use, with several suggesting that running the product in the engine for a short time before an oil change leads to impressive results—transforming the oil from sludge-like to clear, in some cases. While no product can promise a complete clean, many customers feel that this engine flush comes very close to delivering on its claims, making it a reliable choice for maintenance. Overall, the STP Super Concentrated High Mileage Engine Flush is viewed as a good investment for car owners looking to maintain and extend the life of their engines. **
