**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.

### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ very good product
*by D***Z on December 22, 2025*

It works very well, highly recommended.

### ⭐⭐⭐⭐ 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.
