Q: How much should i use for 2011 chrysler town and country and also would i apply this after an oil change?

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. If you have any other technical questions, feel free to contact our Technical Service Professionals at 800-345-6572 or if you would prefer you can use the contact us page on our website.

Q: I have a 1992 Mitsubishi Montero. Would you recommend to use half a bottle, 3/4 of a bottle, or a full bottle?

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.
