Slick 50 Original Engine Treatment | 32 oz., Single

I first used Slick 50 in the late 80s when it debuted and things change, right, but the description says "Original Formula" so I'm hoping that's not just sales hype One thing I noticed immediately is that the 80s formula's instruction was to drive at least 50 miles after adding this to fresh oil (to allow it to circulate through and adhere to the lifters etc) and it was a "once and done" additive... but the instruction on THIS modern "original formula" didn't say anything about driving ANY distance.. AND it's recommended to add once a year.. so I'm wondering if the manufacturer realized a "once and done" formula is bad for sales? which would logically mean it's not actually the original formula, wouldn't it? In any case, I *will* say that just as I was aiming for, it stopped the lifter's tapping noise that we old-car owners experience when warming up the car (that a simple oil change doesn't fix) which makes me happy, and I'm hoping that just like in the 80s that my engine will keep on running smoothly even when the oil's a little low ((in the 80s after driving it the recommended 50 miles, my bf checked the oil and it was bone dry!!! but the engine was running smoothly-- neither of us knew why the oil disappeared but I never had any problems for the next 6 years I owned the car)) So... as far as needing to add it again in a year.. only time will tell

Its slick 50 do I need to say more !!?? Every other oil change my 1998 jeep still going no valvetrain wear yet no clicking SLICK FIFTY will always be in my cars

My Toyota Tacoma V6 has over 200k miles, there was a slight knock, I've added this to the oil and ever since the engine has been quiet. 10/10 works, reduced engine noise, and haven't had any issues.

great product. used for 37 years. vw used for 50 years, gmc truck 25 years. no other product comes close.

Even when I was in my "Twenties", 55 years ago, Slick-50 was around 1969 to about 1979, this product was WELL known in the Automotive Repair World !!! Slick 50 was developed by an "Automotive Wizard" I think in the1950's, Hence the Name !!! I think ?? The Engine oils "Waaaaaay" back then were just "Plain-Jane" oil(s) Not even High "Detergent Oils" at first, these were meant to keep the (INSIDE) of your engine "Clean" !!! Way back then for those "Monster" high-cubic inch displacement engines that the Car Makers pushed on the Markets, since they were in "Cahoots" with the Oil Companies !!! Also, Oil changes were Kind of "Neglected by the Average Owner (Not All), Maybe a "Religious" Once A Year Oil Change !!! No such things like "Jiify-Lube" or "Grease-Monkey", etc. etc. These days as engines came down in size (CID) starting with the influx of "Foreign Cars, European and Asian Vehicles, almost all of these Cars and Small Trucks had much smaller engines, "BUT" More of a "Demand" or "Burden" on them even though the "Engineering" !!! and the "Technology" and the Precise Manufacturing Tolerances became "Vastly", "Vastly" Improved !!! Many with 4 cylinders or even (three) cylinders !!! These also had smaller oil capacity engines (Usually) and sometimes less than 4 Quarts would be enough for an oil change (With Filter) !! Using ONE quart of Slick-50 was quite a Great, Great, thing especially if you did the Job yourself or just had the oil change "Place" add" it for you !! I Believe that this Product does make a difference and I use it in my Mercedes E-350 V-6 every oil change which is generally about 4,000 miles or so. Mercedes's recommendation is, 13,000 miles !!! NO, NO, NO !!!that's a little bit too many miles for me, maybe only once every two years, which is too long for me!!! I could "Bore" all of You and GO ON and ON, but that's enough for now !!! Thank You Amazon and Your Suppliers for Great Products, Great Prices and Great Shipping Always !!! (P. S.) My usage of Slick-50, Is to "Squeeeeeeze" a little more "Miles-Per-Gallon" out of My Trusty "BENZ" !!!!

So far, there is a noticeable difference in auto mileage after just 2 weeks. Mixed feelings about the product. My overall concern is any long term engine damage develop as a result of Teflon usage. There is nothing to directly claim that. Most mechanics agree, just change oil often and that is enough. The Hyundai engine has 70K miles and uses some oil by design is what I am told - add oil or else between regular changes. It seems reasonable Slick 50 usage would help especially and older engine or perhaps extend the life expectancy. After all, engine failure will happen anyway at some point. Maybe extend engine survival for a few years. That would outweigh any potential long term damage. Purchased at friend recommendation then read the Blogs about Teflon. There were some lawsuits over Teflon that the product uses but nothing directly targeting Slick 50 itself. Federal Trade Commission agency charged Slick 50 with "making false and unsubstantiated advertising claims". The advice I got was product is for engines that get used often. Engines that sit a while, oxidation can build up as a result of product causing damage.

オーバーホールではなくこれで何とかならないかと思い、１１万キロ走行のターボのK-CARに使用しました。 よく効きました。500ｋｍ走行でもオイル減らなくなりました。ノイズ軽減やパワーも少しずつ回復しているように感じます。 シリンダーの壁やバルブガイドなどがコーティングされていくといいなあと思っています。

I use this in all my engines

Great item .. fast postage .. thanks heaps

I've been using this product for many years on many cars. I swear by it!
