Review: Clean out your fuel system!! - Wonderful for my vehicle that had been sitting for almost a year without being driven. Helped to clean out the system!
Review: Stuff works great for injector knock - Used on my 2016 corolla with 180k. Noticed the motor had a knock that would come and go so I knew the noise was an injector and not a lifter so I dumped a bottle in and problem was not only gone after a half tank of gas but the car ran better at idle.

## Questions & Answers

**Q: Just purchased and need to put into my car.  I have a half a tank of gas in the car.  Does this need to be put it when tank is near empty only?**
A: The most helpful answer is to add this product when the tank is full or when at the gas station filling up. Do not run the product on an empty tank and expect it to work like gasoline. If you add it to a half full tank of gas you might not get as good a result as when the tank is full.

**Q: I have a 2010 honda civic ex sedan. what is the difference this stuff and lucas 10003 upper cylinder lubrication & injector cleaner 32 oz.? thank you.**
A: Different stuff in them, but both are suppose to lube the upper cylinder real deep like..

**Q: How many gallons does it treat?**
A: I think it cleans up to 25 gallons.  I use it once a month and wont use anything else. but i also drive about 1000 miles a month.  Just dont over use it or it will cause some problems.    Keeps your fuel system and intake clean.

**Q: I have a 2002 dodge ram 1500 engine size 5.9
 and I usely use sea foam so my question is whats the diffrence between the two?????**
A: I've used both of these products to clean my engine internals, fuel system etc. I have an Infiniti G35 with a 3.5 V6. I can't really speak to the difference between the two products in detail other than reading and researching the ingredients and purposes of each. However, I used to have really bad pinging due to carbon buildup and tried Seafoam and Lucas deep clean... But I found that they relieved symptoms only temporarily. Now I exclusively use Gumout Multi System Tuneup as it works much better than Seafoam and Lucas. It has a higher concentration of P.E.A. which is scientifically proven to clean engine internals and fuel system components. I would also give high marks to Redline SL1 and BG 44K but they are more expensive. Watch reviews/tests of Gumout MST on YouTube via Scotty Kilmer and several others... Best of luck to you...

### ⭐⭐⭐⭐⭐ Stuff works great for injector knock

### ⭐⭐⭐⭐⭐ Works
*by P***Y on October 17, 2025*

This has worked, so far I’m about 1/3 of a full tank of gas through it. Idle is much better and smoother. I didn’t believe it at first, because nothing happened. But recently I notice a big difference. My engine is running perfectly, better than ever. I rated this product excellent.
