Would you recommend to use half a bottle, 3/4 of a bottle, or a full bottle?** A: I would use 3/4 of a bottle. I looked up the 1992 Mitsubishi Montero. It looks like it can have two different engines (the 3.5L or 3.8L). Both engines have an oil capacity of 4.9L (5.18 quarts). The bottle says to use 1/2 bottle for 4.4 quarts and a 1 bottle for 6 quarts. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Product is great *by J***Y on July 25, 2026* terrific, worked wonders ### ⭐⭐⭐⭐⭐ Really works *by S***N on October 31, 2025* Works. Had a small leak and i flushed the engine, changed the oil adding the stop leak with the new oil. Ran the engine as instructed to, no leaks and its been over a month. Was recommended to me, and it was worth it. ### ⭐⭐⭐⭐ Had multiple leaks, heavy oil loss *by K***K on January 10, 2025* As my car get near 15 years old and still a daily driver had started to experience many leaks. The BMW community says not to use the product in your BMW. I have a BMW 323i and with the age and mileage was looking at putting a couple thousand into repairs so gave this a shot. Multiple leaks were resolved while one weeper persists. Have ran for over a month with minimal oil loss and improved performance. I did end up flushing out the system after running it with this product in it for the month. ## Frequently Bought Together - Bar's Leaks OS-1 Oil Seal Engine Oil Burning and Leak Repair, 16.9 oz. - Bar's Leaks 1000 High Mileage Engine Repair, 16.9 oz | Restores Performance, Increases Compression & Horsepower, Stops Leaks, Noise & Smoking - Bar's Leaks High Mileage Transmission Repair-It, 16.9 Fl 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.sn/products/55894285-oil-seal-engine-oil-burning-and-leak-repair-os-1](https://www.desertcart.sn/products/55894285-oil-seal-engine-oil-burning-and-leak-repair-os-1) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-09*
