Stanadyne additive is one of the better additives with regards to helping to keep the injectors lubricated during use which also helps to keep them clean and therefore greatly aides in cooling the injectors which are the 3 components of any good diesel fuel; Fuel for combustian-Lubrication of pumps & injectors-Cooling of Injectors, therefore, longer life expectancy! The idea of increasing the cetane rating might be true for some of the additives one can buy, but that is really not the reason to buy any diesel additive! DEF is injected after the combustion process and only used to help dissolve and burn out any particulate matter being emitted in the exhaust. **Q: How often do you use it? Is every fill up ok?** A: Yes I use 6oz every fill up it is great for the engine and increases power **Q: What is the dosing ratio of additive to diesel fuel?** A: .26 ounces per gallon of diesel. ## Frequently Bought Together - Stanadyne Diesel Performance Formula 38566, 64 Ounce - Stanadyne 38561 Diesel Lubricity Formula, 64 oz - Stanadyne 43566 Performance Formula Injector Cleaner, 32 oz --- ## 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.in/products/6914051-diesel-performance-formula-38566-64-ounce](https://www.desertcart.in/products/6914051-diesel-performance-formula-38566-64-ounce) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-09-25*
