It seems to live up to its promise of a gentle but effective cleaner.
I have two 289 Ford 1966 cars. Both had greater response time after cleaning.
Without dynamo data it would appear to work better than most products found in auto parts stores.
After using several of the products found in auto part stores with not much for results. I stumbled upon archoil products and read the reviews and decided to give it a try. WOW ! what a difference in throttle responce, in just a short amount of time. I knew it was carboned up from letting it idle in the morning to warm up, and driving carefully on snow and ice covered roads, you never get a chance to blow the cobwebs out of motor. Using AR6400G in my Raptor has brought back the performance I remember the first time i drove it! Don,t waste you money on the crap at gas stations, Walmart, auto part stores, if you want results, use ARCHOIL AR6400G it really works!!!!!!!
