That way you can drive your vehicle for however long. Probably a good 2 days, drain the oil/ fix the problem, then refill with fresh oil. **Q: do you really need the yellow goggle to see the dye?** A: I had no problems seeing the dye without the glasses. **Q: can this dye be mixed with mineral oil and used in smoke test machines** A: The answer is yes. I used it in my smoke machine to test an engine in my 1996 BMW Z3 1.9. It worked fine. **Q: So i just pour all of this bottle into engine oil and look with blacklight?** A: Thats exactly what I did to locate a hard to find oil leak. BTW: to get a clean read, you will need to clean the engine beforehand, add the dye and then drive 20 miles or so to locate the leak. ## Customer Reviews ### ⭐ Useless *by A***Q on 24 August 2024* Does not identify leak ## Frequently Bought Together - InterDynamics Certified Auto Pro Oil and Fuel System UV Dye Leak Detection for Cars & Trucks & More, 1 Oz, 374CS, Universal - REALHUNLEE Air Conditioner UV Dye Leak Detector, Pro Auto Oil AC UV Dye Leak Test Detection Tool Kit 68 LED A/C UV Flashlight Detector with Protective Glasses --- ## 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.dk/products/306971870-interdynamics-374cs-certified-a-c-pro-oil-and-fuel-systems](https://www.desertcart.dk/products/306971870-interdynamics-374cs-certified-a-c-pro-oil-and-fuel-systems) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-05*
