I am planning to buy a BMW M340i for long-distance trips into wildlife reserves, as I have a strong interest in wildlife. I have two concerns, one is the E20 petrol. The M340i engine is a high-compression engine and needs high-octane fuel. With E20 petrol now available across the country, will this cause any issues for my engine? The other worry is the low tyre profile on bad roads, which may lead to punctures. Do give me your best advice.

On E20 fuel, you don’t have to worry at all. In fact, you should be happy because the base octane rating for E20 fuel has jumped from 91 octane to a minimum of 95 octane or even higher. Hence, this suits the 11.0:1 compression ratio of the M340i’s B58 engine, and now, instead of hunting for high-octane fuel, you can use fuel anywhere, as you are now assured of 95 octane.

A bigger concern are the low profile tyres, which are staggered with 225/40 R19 in front and an even lower 255/35 R19 at the back. This could be a problem on bad roads, where the tyres could be vulnerable to impact damage.

One way to protect the tyres against punctures, but not guaranteed, is to pump up the tyre pressure by about 3-4PSI to make the sidewalls stiffer. This reduces the flex in the sidewalls and makes them more resistant to impact damage, but quite honestly, the BMW M340i is not a car we would take into the jungle!

I am planning to buy the Mahindra XUV 7XO AX7T diesel manual, but I am concerned about DPF issues. Some of my friends say that modern engines are more advanced now, and there is no need to worry. What is your view?

For mixed city and some highway use, you can go ahead with the Mahindra XUV 7XO AX7T diesel manual. Don’t drop it only because of DPF worry. The DPF is a filter in the exhaust that catches soot, and it needs a bit of heat and steady running now and then to clean itself. On the latest XUV 7XO, Mahindra has improved the software and the system over the past few years, so your friends are right that things are better now, but it is not completely worry-free in every case.If your daily use is mostly short trips in slow traffic, the filter may not get hot enough to clean. That’s when you may see a warning. The fix is simple: take the car for a longer drive on a clear road for 15-20 minutes, keep the engine revs a little higher than usual, and don’t switch off if you see a “drive to clean” message. Do this once in a while, even before any light shows, if your routine drive consists of only short hops. Also, fill diesel from a trusted pump, avoid driving at very low speeds in a high gear, and at delivery, ask the service advisor to confirm the car has the latest software.If you do some highway runs every week or two, DPF issues are rare. Where it can be a pain is if you mostly do many 2-3 km trips and almost never leave the city. So, if your usage is mixed, you’re fine to buy it. If it’s almost all tiny trips, think twice about diesel. Overall, with a bit of these simple habits, the AX7t diesel manual will serve you well.

Hi, I am planning to purchase an SUV. My family has seven members (six adults aged 25+ and 53+, and one child). Currently, I own a 2025 Maruti Baleno (petrol), a 2018 Maruti Swift Dzire (petrol), and a 2010 Maruti Swift (diesel). I am planning to exchange my 2018 Swift Dzire for an upgrade. I am considering the Toyota Innova Crysta, Mahindra Scorpio N and Mahindra XUV 7XO. However, the base variant of the Innova Crysta (GX) is not available for booking at the dealership. My budget is around 25 lakh. Please suggest the best option for my family with low maintenance. Thanks in advance.

Seven people, mostly adults, and a Rs 25 lakh cap points to one clear choice, the Mahindra XUV 7XO diesel. It rides smoother than the Scorpio N and the Innova Crysta. The step-in height is friendlier for elders, and you get more features at this price.One thing to note is that the XUV 7XO's third row is not the most spacious around. Alternatively, also consider the Kia Carens Clavis diesel. It is refined and comfortable, easy to drive in the city, and the third row is comfortable for adults.We would avoid the Scorpio N for your use. Its third row is tight for adults, access is not easy, and the high step can bother older family members, even though it is very strong on rough roads.Overall, the XUV 7XO diesel 7-seater fits your family and budget best.

Hi, Abhijeet this side. I am looking for a car with good mileage, as my daily run is around 100 km from Bhiwadi to Gurgaon and back. My usage is roughly 60% highway and 40% city traffic, although highways can get heavily congested during peak hours. I have a family of five, including my parents, and I prefer using my car for long trips rather than public transport. EVs are not an option for me due to infrastructure concerns. Currently, I own a Nissan Magnite XV Red Edition (manual, NA engine), but its mileage has dropped to around 11.5 kpl. I am not sure if this is due to E20 fuel. I plan to sell this car and do not want to keep two vehicles. Please advise whether I should opt for a hybrid or a diesel car. My budget is up to 20 lakh, but I would prefer to stay closer to 15 lakh if possible. It all depends on your guidance.

Opt for a strong hybrid, specifically the Toyota Urban Cruiser Hyryder strong hybrid. It is the best fit for your usage and long-term ownership. Your daily running is very high, with a mix of highway and heavy traffic. In this kind of use, the stop-and-go sections hurt fuel efficiency the most, and this is where a strong hybrid makes a clear difference. It can run on battery at low speeds, cuts fuel use in traffic and makes the drive smoother and less tiring compared to a diesel or petrol car. Over time, this will reflect in significantly lower running costs.A diesel car, such as the Hyundai Creta or Kia Seltos, will still do well on open highways and feel stronger during quick overtakes. But your route is not purely highway, and the traffic component reduces that advantage. Also, being in the NCR region, diesel ownership comes with long-term limitations, which the hybrid avoids completely.
