**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.

### ⭐⭐⭐⭐ it really worked on my 2007 bmw 740 in dubai
*by T***N on 29 January 2022*

my car smoked a lot on high throttle and when the traffic was busy or parked for 5 to 10 minutes, the exhaust always smoked and smelled I spent a lot of money on some additives, and got advice from the garage for the repair very high repair cost to replace valve seals, I also ordered many kinds of pcv valve to replace but no success i have tried this product and it worked, it's not 100% but it's also 70%, my car has reduced smoke, and has reduced odor, i think it will work by adding it every time oil
