Review: Works great - My 2011 RAV4 has 380,000 miles on it and was throwing a code that was likely a catalytic converter as it wasn’t resolved after replacing the O2 sensors. After three bottles of this product (1 whole bottle in the first tank and 1-2 oz per tank thereafter) the check engine light has gone off and stayed off for 500 miles or so. It is also running smoother and the mpg is back where it should be. I definitely recommend this product. Review: This gasoline additive actually worked - Definitely noticed a difference in idling and smoothness of acceleration after using one bottle in 2001 Chevrolet 5.3L Suburban with high miles. Have tried other additives with no noticeable difference so Shaeffer's additive must be doing something positive. ## Features - Optimizes performance and fuel economy up to 5%. - Improved drivability, smoother idling. - Reduces emissions, exhaust smoke and particulates. - Keeps injectors free from varnish, deposits and gum. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00JF2L0P8 | | Best Sellers Rank | #765,528 in Automotive ( See Top 100 in Automotive ) #359 in Fuel Additives | | Brand Name | Schaeffer Manufacturing Co | | Compatible with Vehicle Type | Car, Truck | | Container Type | Bottle | | Customer Reviews | 4.6 4.6 out of 5 stars (52) | | Global Trade Identification Number | 00744954000395 | | Item Type Name | Gasoline Additive | | Liquid Volume | 12 Fluid Ounces | | Manufacturer | Schaeffer Manufacturing Co. | | Manufacturer Part Number | 0131C-021S | | Manufacturer Warranty Description | Check with manufacturer. | | UPC | 744954000395 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Schaeffer Manufacturing Co - **Liquid Volume:** 12 Fluid Ounces - **Package Information:** Bottle - **UPC:** 744954000395 - **Vehicle Service Type:** Car, Truck ## Images ![Schaeffer Manufacturing Co. 0131C-021S SoyUltra Gasoline Additive, 12 oz.

After three bottles of this product (1 whole bottle in the first tank and 1-2 oz per tank thereafter) the check engine light has gone off and stayed off for 500 miles or so.

I definitely recommend this product. ### ⭐⭐⭐⭐⭐ This gasoline additive actually worked *by O***E on December 26, 2025* Definitely noticed a difference in idling and smoothness of acceleration after using one bottle in 2001 Chevrolet 5.3L Suburban with high miles. Have tried other additives with no noticeable difference so Shaeffer's additive must be doing something positive. ### ⭐⭐⭐⭐⭐ Improved old riding mower *by S***N on February 23, 2019* Tried it in one of our old riding lawnmowers, that had been hard to start and ran rough. Just to see if it would do anything. Added 6 ounces to the fuel and the engine ran like new. Blown away with the result. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/22676481-schaeffer-manufacturing-co-0131c-021s-soyultra-gasoline-additive-12-oz](https://www.desertcart.tn/products/22676481-schaeffer-manufacturing-co-0131c-021s-soyultra-gasoline-additive-12-oz) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-27*
