Liqui MolyTruck Series Complete Gasoline System Cleaner | 500 ml | Petroladititive | SKU: 20250

I was hesitant to try an additive (for fear of damage) but after lots of research and reading lots of reviews plus forum content; we tried this and it worked!!! It has been several months and slow response issue in son's 2002 Tundra has not returned. Pretty sure it did what it was supposed to and cleaned out whatever gunk from last 20+ years or at least enough gunk to noticeably improve performance :) Nicely packaged German made product. Our very honest & talented mechanic shared that he has used this brand on his personal vehicles so that is encouraging. Overall low cost for better running truck!

This is a good product I love it will keep on using it

added to the 2019 F150 - and the engine started to work noticeably better. less vibration, I pretty much don't hear the idling engine from a cabin. So it does work, let's see for how long the effect will stay

I’m usually skeptical about cleaners, additives etc claiming they will do something…with LiquiMoly they aren’t kidding their product will really do what it claims. Just by smelling it you can see how strong and concentrated the cleaner is. I use this on my 2014 Chevrolet Tahoe every now and then to keep everything in the fuel system working properly. You notice a difference almost immediately, the throttle response is improved and my MPG has actually gone up by about 2-3 mpg it’s definitely doing something. Anything LiquiMoly sells works like magic from my experience so…try it you won’t find anything else that works better in my opinion.

Liqui Moly will always be trusted in my book. I've used many of their products with great success including MOS2, valve clean, jectronics, engine flush, ceratec, oil saver, you name it. I've used it mainly in Japanese and American cars. Quality stuff from a German company.

I mean we never really know of or exactly how these things work. Making it very difficult to leave a review. All I can say is that I remember when I was a child my grandfather, the mechanic, would swear that STP oil treatment is the best thing invented in your truck will never die. If you use it every oil change. He proved that to me by dipping the tip of a flathead screwdriver in it and seeing if I could pinch it and keep hold….. Never could… So that’s what I’ve always used. I’m giving this four stars because I did that exact test and it felt just like it did 25 years ago. I hate to say it, but my grandfather would probably be proud of this oil treatment because it contains something his didn’t.. MoS2.

The best I’ve ever used

One person wrote that if your vehicle has 34k b on it to start using it right away I started at 29800 and love this product.Will try the oil treatment next next as I a m rue for a change next month.
