Hello everyone, first of all I thank those who read everything and help me. I come to ask for your opinion or advice on this subject, since, I know little about cars and putting CNG on a car (cost / benefits). Well it turns out that I have a Patagonian 2012 Partner of 1.4 (base), and currently has 75 thousand kilometers, I bought it exactly 14 months ago (at that time I had 63 thousand km), I mean that I did about 10 thousand km in one year. But since the gasoline is expensive here in Argentina and I always heard that it is much cheaper to put CNG, eh is thinking a lot and also now my brother (we live in the same house) asked me if from time to time I could not lend him the car for a while, which will be used more. The use that I gave to the car in general was particular (since I study), I went out some weekends and in the week very rarely except for shopping or something like that, and since the car is something big, and if I were to change it, it would be a slightly smaller one but that it is a somewhat spacious inside. (I DO NOT want the inside to be like a fiat siena) since they are cute but little space in the back. Then I thought about whether it is convenient for me to change the car for another one that already has CNG (and for which?) Or if it is convenient for me to put CNG on it (find out and they threw prices between 38-45 thousand pesos for two 30 L tanks) and as I don't have all the money on top (I need 20,000 that my brother said he lends me), but I decided to ask around here before deciding. I clarify that if YOUR advice was to change the car for one with CNG, obviously I would prefer it to be with an equivalent in price or less than mine (I bought it at 200 thousand pesos and I clarify here that the car has never had any type of crash so far, Only small scratches that usually appear for use, has made the change of belts, oil and filter (approx. 3 months ago it was made)) DOUBT about the 2 CNG tanks: Are those tanks, full, equivalent to how many liters of gasoline? Thank you so much for everything
