## Description

Your vehicle is a good candidate for Bar’s Leaks Oil Seal Engine Oil Burning & Leak Repair if it does not consume more than one quart of oil per day. We have designed this product to work in all gasoline and diesel engines including turbocharged, EcoBoost, hybrid and even racing engines. . This covers 3, 4, 5, 6, 8 and 10 cylinder engines in all cars, trucks, vans and SUV’s. Our product can also be used in heavy-duty applications referencing the appropriate dosage level. This applies to a wide range of other motor applications too: tractors, boats, RV’s, motorcycles (including wet clutch), ATV’s, lawn equipment.

Review: Really works - 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.
Review: Works, but doesn't actually fix anything - Used this product in a 2012 Civic that was burning a quart almost every 500 miles. This almost put a complete stop to that. I had to combine it with another product in order to stop the oil burning almost completely, but this did decrease the amount of oil burning by at least 40%. Keep in mind this will not fix a broken engine. My civic has a defect from the factory that causes oil blow by - the only true fix is to get new piston rings installed. This wont fix anything - but it will help with oil burning.

**Q: How much should i use for 2011 chrysler town and country and also would i apply this after an oil change?**
A: That vehicle has a 6 quart capacity. One bottle treats oil capacity from 4.5 quarts (4.3 liters) to 7 quarts (6.6 liters). Please use one full bottle after oil change. Make sure you are 1/2 quart low on oil before adding to the system to ensure you do not overfill. Top off with oil after adding if needed.

**Q: I have a 1992 Mitsubishi Montero. 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.

### ⭐⭐⭐⭐ 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.
