Don't worry about being exact in this case more is good and for car size tanks i don't think it matters whether you add before or after pumping. I'm not a representative of Polytron, this how i use it. I'm always leary of these type of products but i think this is the real deal. I notice improvements immediately after i added Polytron GDFC to my fuel: smoother running, better take offs and better MPG however the first time i added GDFC I am using it instead of Stanadyne OEM additive for lubricity since the fed's saw fit so remove sulfur(extreme pressure agent) from diesel. Similar immediately noticeable results from oil additive. ## Frequently Bought Together - Polytron Gasoline Diesel Fuel Conditioner (GDFC) 12oz (354ml) Bottle - Military Industrial Grade - Polytron Metal Treatment Concentrate Oil Additive (MTC) 1/2 Qt (16oz/473ml) Bottle - Military Industrial Grade --- ## 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/492341110-polytron-gasoline-diesel-fuel-conditioner-gdfc-12oz-354ml-bottle-military](https://www.desertcart.jp/products/492341110-polytron-gasoline-diesel-fuel-conditioner-gdfc-12oz-354ml-bottle-military) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-28*
