Rated 5 out of 5 by My Dinosaur I have been using Slick 50 regularly (every 50,000 Mi.) since 1999 on my 1999 Mercury Grand Marquis. The car now has 167,000 miles on it and performs excellently. The overall gas mileage on the vehicle registers at 25 mpg, and varies by a few tenths of a mile if we stay in town for a longer period of time. I believe Slick 50 has contributed to this great performance. October 1, 2016
Rated 5 out of 5 by this is Best product EVER! I live in Florida and have a race car engine my oil pick up tube was block before this happen had use slick 50 when my oil pick up tube was plug up not knowing this happen the temp was 98 drove 100 miles round trip notice my oil pressure was zero. Pulled engine out store in shead for 2 years never went out turn crank in 2 years. One day wanted find out what had happened was told engine should be lock up for not turning crank in 2 years . I turn the crank to my surprise it turn. Fix oil pick up tube change oil engine ran like brand new. Thanks to slick 50 I rate 20 stars if I could this product saved me thousands of dollars October 1, 2016
Rated 5 out of 5 by Wisest protection for your vehicle I've used Slick 50 for 30 years on my several different vehicles. An engine flush, synthetic oil, and Slick 50 has kept all my new and used vehicles running smooth as butter. August 21, 2016
Rated 5 out of 5 by this product is different from synthetic oils Regardless that many say synthetic oils are just hype and just a marketing ploy, Slick 50 really works well for old engines to help seal leaks and to extend the life of the engine. I have used it for close to 30 years after having good experiences from early on. August 4, 2016
Rated 5 out of 5 by Super slick 50 I have been using this for 30 years. It has saved several motors of mine with blown head gaskets or holes in oil pans. Amazing what a little Teflon in the motor can do. Also help engines to run cooler, esp. New tight motors. Better gas mileage? Probably but small like 3%. This is cheap and great. April 4, 2016
Rated 5 out of 5 by Slicknessistery This will get you better gas mileage, cooler engine temp and save you engine in many oil failure modes August 11, 2015
