STP Ceramic Oil Treatment, Protective Coating and Anti-Friction Technology, 15 Oz (19387)

You may ask, with this being a liquid, how is it dry?? Well, I'm referring to the Ceramic Si02 component, which is a Dry Substance that is mixed into an oil based carrier so that it can circulate through the Engine and come into contact with vital moving parts of the Engine such as the Pistons and Rings, the Crankshaft Bearings and Connecting Rod Bearings, as well as the Camshaft(s) Lobes and Bearings and Valve Guides, to name a few. Ceramic has been scientifically (There is a Video) proven to withstand up to 1,200 Degrees Fahrenheit, and will not break down or gum up your system like other products that use other known So-Called Dry Lubricants.... It does NOT kill your warranty either!!!!! As far as Fuel Consumption and Economy is concerned, I cannot say I have noticed a marked increase in Fuel Efficiency, plus my foot is made of lead, but that is another issue, lol.... It might under the right circumstances, IDK. As far as the sound and performance of my Engine, I did notice a marked decrease in noise at Idle, and much less vibration of the engine at idle, the Engine runs extremely smooth now, that I can honestly say is happening. Also, my engine seems to be quite a bit more responsive and free using the STP Ceramic too. It just feels like it was given a bit of a boost, it accelerates much better, its very smooth, and I can feel it pulling harder through the Power Band than ever before, and that can only be because the moving parts are indeed being much better lubricated, friction is sharply being reduced by the Ceramic, and the engine is just free to cycle much better during operation. Again, other products make claims, but when put to the test, they are known in laboratory tests to gum up and break down when subjected to extreme heat, and they doing NOTHING to improve Overall Lubrication of your Engine's most Vital Moving Parts, however Ceramic Si02 cannot and will not break down, it doesn't gum up your system, etc., or anything else, even under extreme operating conditions like, for instance, the Arizona heat in Summer!! I strongly believe this product does what it is intended to do most, and that is add a layer of Dry Lubricant to your engine and allow less wear and more longevity to the life of your engine, and is IMO best used with Premium Synthetic Oil and a Premium Oil Filter. This is my own observation, my opinion based on my experience, I am not trying to sell anything, I am just sharing my personal results, and all I can say IMO, this stuff really works!!

The best oil additive ever. I research thousands of products like this and tried hundreds. I decided to buy this to try it in my hybrid turbo engine. WOW, does it make a difference. The engine is quieter and I am getting 2 miles per gallon. I'm very impressed that I bought another one for my other car which has a V6 Turbo engine. This actually works. It is definitely not snake oil. The price was great. Cheaper than any other auto parts store. The thickness is perfect for 0W-20 and 5W-20. I can tell my engine is now protected especially when the temps are 15 degrees Fahrenheit. Very durable. I highly recommend this to anyone.

I recently decided to try the STP Ceramic Oil Treatment, and I must say, my experience has been outstanding! This product has truly transformed my vehicle's performance, and here's why I give it a solid 5-star rating. Ease of Ordering: The process of ordering the STP Ceramic Oil Treatment was incredibly simple. I found it available on a well-known online retailer's platform, and the search function made it easy to locate quickly.

I received my product just a couple of days after ordering, which was quicker than I had anticipated. The packaging was robust, protecting the bottle during transit, and I appreciated the tracking information provided, allowing me to know exactly when to expect my order. Improvement in Mileage and Engine Smoothness: Before adding the treatment, I ran my engine for about 5 minutes to warm it up, as recommended. This ensured that the oil was at the optimal temperature for the treatment to integrate smoothly. After warming up, I added the STP Ceramic Oil Treatment and took my car for a 15-minute drive to allow the treatment to work its magic. Immediately after the drive, I noticed a remarkable improvement in engine smoothness—there was less noise, and the overall operation felt much more refined. What struck me most was the noticeable improvement in mileage; my fuel efficiency has increased significantly. I’m now getting more miles per gallon, which has made a tangible difference to my driving experience and wallet. Final Thoughts: In summary, the STP Ceramic Oil Treatment has been a game changer for my vehicle. The combination of easy ordering, prompt delivery, and impressive performance results has truly exceeded my expectations. If you're looking to enhance your engine's performance and improve fuel efficiency, I highly recommend giving this product a try. You won't be disappointed!

Can't tell whats going on in my 2004 forester, but it quieted it down, runs nice and smooth, a little more pep, and the fuel millage has definitely has gone up.. I never measured the millage before using it, but I will edit this post with what I am getting now.. In a few weeks..

This is the best thing I have ever tried in our cars! My ecoboost Mustang increased MPGs by 3 and wife's Escape increased by 4. It instantly quieted down both engines. My Mustang has a setting on the dash to read cylinder temperature. It went down about 20 degrees! That should be an engine saver for sure. Here's the downside. It doesn't last in to the next oil change. MPGs went down right away after an oil change. On my last gas fill up with the STP in there the MPG went back down to what it was before adding the STP. So, it kind of lets you know when to change your oil because your MPGs will go back down from the dilution of gas and stuff ruining the oil and STP effects. I'm going to put it in every oil change. I'm betting it helps extend the life of the engine between the slickness/smoothness of the engine and running cooler. Amazing stuff for sure.
