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 ### ⭐⭐⭐⭐⭐ WORK GREAT *by on Reviewed in the United States July 7, 2026* WORKS EXCELLENT FIXED MY PROBLEM ! THANK YOU ### ⭐⭐⭐⭐⭐ Product worked Perfect on my 2012 BMW 750Li *by on Reviewed in the United States June 28, 2021* The product worked on a 2012 Bmw 750Li that was smoking when at a light, in traffic, or in line at fast food..... Was fine when diving as long as not at a stand still for over 3 to 5 Mins or stop and go traffic..... I fell like it was the valve seals leaking ao I brought this in hopes it would work.... The initial one I was going to try seems to stay sold out..... I decided to purchase before a trip that was 200 miles away to give it a chance to work..... I put it in the night before for 15 to 20 mins 1st and as always it started smoking...... On the trip back 2 days later before making it home we stopped at Zaxby's and about 6 cars were in line.... I say oh boy because it always smokes after a few mins in line soni have to cut the engine off and turn back on after a car move up..... But this time for the 1st time it did not smoke.... I was amazed and kept looking for the smoke but never came..... So the product works.... Dont know if it already worked on the first 200 mile because i did not test until i retured so I drove over 400 miles before i test it.... But no smoke at all...... Probably will cost over 5k to change all the valve seals if not more. ### ⭐⭐⭐⭐ Had multiple leaks, heavy oil loss *by on Reviewed in the United States 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-bars-leaks-os-1-oil-seal-engine-oil-burning-leak](https://www.desertcart.sn/products/55894285-bars-leaks-os-1-oil-seal-engine-oil-burning-leak) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-28*
