**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.

### ⭐⭐⭐⭐⭐ Funciona!!!
*by J***G on 26 October 2025*

Magnífico. Tengo una de mis motos con casi ya 40 años y algunas fugas de aceite motor severas. No era una gotita, era ya casi pequeños charcos. Decidí probar este mejunje y el resultado es de 10. Han desaparecido por completo. No hay fugas ni gotas ni nada de aceite ya bajo la moto. Cuesta creer en estos productos milagrosos, de hecho no creía en ninguno pero como tenía mucha pereza y poca pasta para levantar el motot y gastar más de 200€ en juntas decidí probar por las reseñas positivas que leí a ver que tal en mi moto y si! Funciona 🙂 Apto para motores con embrague en baño de aceite o sea que lo puedes poner en tu moto sin problema... 😜
