My budget is Rs. 12-13 lakh, and my monthly running is around 1,000 km. I am planning to buy a manual sub-4m SUV. I am confused between the Tata Nexon and Mahindra XUV 3XO. Which one is better in terms of safety, features, mileage, and power? I am planning to buy a diesel. Should I go for petrol or diesel? And between the Nexon and XUV 3XO, which one should I buy?

With a monthly running of 1,000km, diesel is not the most financially sensible choice today. Modern diesel cars are more expensive to buy, and the price difference between petrol and diesel fuel is not as significant as it once was. At your running, the savings on fuel will take a long time to offset the higher purchase price. Both the Nexon and 3XO petrol engines are efficient and well-suited to your usage, and you will avoid the additional complexity and potential long-term maintenance costs associated with diesel engines.

Between the two cars, the Mahindra XUV 3XO is the better fit. This Mahindra car is one of the most spacious compact SUVs in the segment, with a wide cabin that makes it a genuinely comfortable five-seater. It is also feature-rich and has a strong safety record. The Nexon is a good car, but the 3XO offers better value for money and a more spacious cabin at a similar price point.

Go for the Mahindra XUV 3XO petrol manual. It will give you a better ownership experience and make more financial sense in the long run.

I own a January 2018 Tata Nexon petrol. It is an E10 compliant car that I have to run on E20 due to the government mandate. Till date, it has clocked 1,01,200 km without any issues. I want to know your views on usage of Petrol additive Iftex System G and G+. As suggested by the manufacturer, I plan to use System G+ for one-time cleaning, followed by dosing System G with petrol thereafter. I would be grateful if you could explain their impact on the car.

You have a 2018 Tata Nexon petrol that has run over 1 lakh km without any issues, and you are now concerned about running it on E20 fuel and whether using Iftex System G and G+ additives will help. The good news is that your Nexon has already proven itself to be a reliable car, and there is no evidence to suggest that running E20 in an E10-compliant engine will cause any immediate or catastrophic problems. The main impact of E20 is a slight drop in fuel efficiency and potentially increased wear on some rubber fuel system components over a very long period.As for the additives, using System G+ as a one-time cleaning dose followed by regular System G dosing is unlikely to cause any harm, but it is also unlikely to make a dramatic difference. Modern fuels already contain detergents, and your car has been running well for over 1 lakh km without additives. If you want to use them for peace of mind, that is fine, but do not expect a night-and-day improvement. The most important thing is to continue with regular maintenance and keep an eye on fuel system components over time.Overall, your Nexon has already proven itself, and E20 is not something to be overly worried about. Additives are a personal choice, but they are not a magic solution.
