Review: Cheap way to get PEA - I think redline is a better value and it’s worth it to pony up the extra $5-$6, but this a great product. Use additives with PEA once every few thousand miles(preferably before oil changes), or add a bit at every fill up, especially if you don’t use good gas Review: Gas cleaner & injector cleaner - Great product works good 👍👍😊 ## Features - Greatly reduces harmful NOx emissions - Removes carbon deposits - Totally eliminates knocking and pinging - Raises mpg and performance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003JTYGPO | | Best Sellers Rank | #5,820 in Automotive ( See Top 100 in Automotive ) #28 in Fuel System Cleaners | | Brand | Lucas Oil | | Brand Name | Lucas Oil | | Capacity | 16 ounces | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.7 out of 5 stars 2,021 Reviews | | Global Trade Identification Number | 00049807105129 | | Included Components | 1x 16 ounce bottle | | Item Form | Oil | | Item Type Name | fuel system cleaner | | Item Volume | 473 Milliliters | | Item Weight | 170 Grams | | Manufacturer | Lucas Oil | | Material Feature | Biobased | | Material Features | Biobased | | Model Number | 10512 | | Number of Items | 1 | | Part Number | LUCA10512 | | Recommended Uses For Product | Travel | | Scent | Citrus | | Size | 16 Fl Oz (Pack of 1) | | Special Features | Concentrated | | Specific Uses For Product | Engine | | Surface Recommendation | Acrylic | | UPC | 049807805128 049807405120 | | Unit Count | 16.0 Fluid Ounces | ## Product Details - **Brand:** Lucas Oil - **Item Form:** Oil - **Material Feature:** Biobased - **Scent:** Citrus - **Specific Uses For Product:** Engine ## Images ![10512 Deep Clean Fuel System Cleaner - 16 Ounce - Image 1](https://m.media-amazon.com/images/I/51vWzMYoSEL.jpg) ![10512 Deep Clean Fuel System Cleaner - 16 Ounce - Image 2](https://m.media-amazon.com/images/I/31ZnrvtTGCL.jpg) ![10512 Deep Clean Fuel System Cleaner - 16 Ounce - Image 3](https://m.media-amazon.com/images/I/31zw+1n9LkL.jpg) ![10512 Deep Clean Fuel System Cleaner - 16 Ounce - Image 4](https://m.media-amazon.com/images/I/71UXZc0T+3L.jpg) ## 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... ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cheap way to get PEA *by G***E on March 22, 2026* I think redline is a better value and it’s worth it to pony up the extra $5-$6, but this a great product.
