Each 12 oz bottle treats up to 20 gallons of unleaded or low-lead fuel, forming a protective film that prevents valve damage and upper cylinder wear. Ideal for off-road and vintage vehicles, this case of 12 offers long-term engine preservation and excellent value, backed by a 4.7-star rating from classic car owners. ## Description Gunk's Lead Substitute allows older engines designed for use with "leaded" gasolines to run safely with low lead or unleaded fuels when used as directed. Replaces lead protection, contains valve seat anti-wear additive, intended for off-road use. Treats up to 20 gallons of gasoline. Review: It does the job!!! - I use one 12 oz. container of Motor Medic Lead Substitute for every tankful of gasoline for my 75 year old Ford with the original flathead engine. I've owned the car for 23 years, have used Lead Substitute religiously, and the engine continues to run beautifully. I don't know how much of the total credit goes to the fuel additive but one thing is for sure.... today's gasoline contains no lead so I add the substitute... and 'the proof is in the pudding.' It certainly can't hurt. I also add a couple of ounces of Marvel Mystery Oil to every fill-up, and that adds even extra protection!! I highly recommend Motor Medic Lead Substitute for any and all engines that were designed to run on leaded gasoline. Review: Case of lead-substitute for classic and antique cars -- an excellent buy! - I've used this gasoline additive on a 70-year-old car, in combination with ethanol-free gasoline for many years. I expect to continue and that is why I ordered this case of 12 bottles. The case of lead-substitute provides considerable savings when compared to buying a single bottle at an auto parts store. ## Features - Allows engines designed for leaded gasoline to run safely with low lead or unleaded fuels - Prevents valve damage and upper cylinder wear in older engines - Coats with a protective film designed to prevent valve recession - Intended for off-road use - Replaces lead protection ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BGSFJUG | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #19,224 in Automotive ( See Top 100 in Automotive ) #242 in Motor Oils | | Brand | Niteo Products | | Brand Name | Niteo Products | | Container Type | Bag | | Customer Reviews | 4.7 out of 5 stars 467 Reviews | | Global Trade Identification Number | 00078698420509 | | Item Form | Liquid | | Item Package Weight | 4.44 Kilograms | | Item Weight | 0.82 Pounds | | Manufacturer | Niteo Products | | Model Number | M5012-12PK | | Number of Items | 12 | | Package Information | Bag | | Package Weight | 4.44 Kilograms | | Part Number | M5012-12PK | | UPC | 078698420509 | | Unit Count | 144.0 Fluid Ounces | | Warranty Description | 90 Day | ## Product Details - **Brand:** Motor Medic - **Item Weight:** 0.82 Pounds - **Item Form:** Liquid - **Package Weight:** 4.39 Kilograms - **Package Information:** Bag ## Images ![Motor Medic M5012-12PK Lead Substitute - 12 oz., (Case of 12) - Image 1](https://m.media-amazon.com/images/I/41XvQgQDxPL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It does the job!!! *by S***I on October 27, 2024* I use one 12 oz. container of Motor Medic Lead Substitute for every tankful of gasoline for my 75 year old Ford with the original flathead engine.
