The approximate dosage is 1 ounce for every four gallons. If your fill up is about 16 gallons put in 4 ounces (1/2 bottle). If your fill up is 20 gallons put in 5 ounces.

Round up or down to the nearest ounce. **Q: Is this also an anti gel?** A: Yes, it includes Cold Weather Protection – improves diesel pour point up to 40°F (22°C), and cold filter plug point by up to 25°F (13°C), depending on base fuel **Q: Should I had it to my empty tank, then fill it with fuel, or fill first, then dump in the bottle?** A: I pump a few gallons in if empty (which I don't recommend for fuel system health) them complete the fill up with diesel fuel. ## Frequently Bought Together - 4 Bottles of Stanadyne 38564 Performance Formula 8 oz Diesel Fuel Additive - Stanadyne Performance * Diesel Injector Cleaner * QTY of 4 - 8oz bottles #43562 - Stanadyne Performance Formula Diesel Fuel Additive 2 Pack of 1/2 Gallon Jugs - Part # 38566 --- ## 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.jp/products/35800930-4-bottles-of-stanadyne-38564-performance-formula-8-oz-diesel](https://www.desertcart.jp/products/35800930-4-bottles-of-stanadyne-38564-performance-formula-8-oz-diesel) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-06*
