Hello Autocar India Team, First of all, thank you for your excellent insights and detailed reviews. I am an avid reader of your website and truly appreciate the depth of information you provide. I have recently purchased the Mahindra 3XO RevX A (Petrol AT, TGDi) and would like guidance on the recommended fuel for this model. Specifically, does this engine require 95-octane petrol (premium fuels such as XP95, Power, or Speed), or is regular petrol sufficient? I have read online but couldn’t find a clear answer: some sources say that after the introduction of E20 fuel, all petrol sold is effectively 95 octane, which adds to the confusion. Could you please clarify what fuel grade Mahindra recommends for this engine and whether using 95-octane petrol offers any real benefit? Looking forward to your expert advice. Kind regards, Kushal Desai

Much appreciated, and thank you for being a long-time reader of Autocar India. 

To answer your question, yes, things have gotten a little confusing after the introduction of E20 petrol, but most of what you've heard is true. Since your new car - a Mahindra XUV 3XO RevX A TGDi AT - is relatively new, it will be E20 compatible. Therefore, you don't have to worry about blended petrol being incompatible with your car or causing it damage.  These vehicles have been built with safeguards against the corrosive nature of ethanol. Any petrol will do, even the most basic type available at any pump across the country. 

Secondly, yes, 91-octane petrol is now effectively 95-octane petrol as ethanol (which has a much higher octane than petrol) raises the overall number. As a result, many fuel brands have discontinued their premium-branded 95-octane option. Instead, only offer 99 or 100-octane (which, incidentally, has 0% ethanol) as the premium option. In short, you now really have just two options - 'regular' petrol (E20 - 95 Octane) and 'premium' (E0 - 99/100 Octane), and you can fill either in your car.

I am looking for an upgrade. Does it make sense to buy the 3XO, coming from a Honda City? Please suggest. (Also open to other options)

If an upgrade necessarily means a larger car for you, the Mahindra 3XO won't be the right move after a Honda City. You'd be best served by midsized SUVs, which measure between 4.3 and 4.5m. Of the current crop of mid-sized SUVs, the Kia Seltos, Hyundai Creta and Tata Sierra are the best-rounded. The new-gen Renault Duster that launches on March 17 also has promise.If vehicle size isn't a dealbreaker, the Mahindra XUV 3XO is a good pick. It's got powerful petrol engines, feels solid, and ride and handling are also impressive. The interior is also spacious for what is a compact SUV, and higher-spec versions pack in loads of equipment too. In fact, a fully-loaded 3XO is better equipped than a fully-loaded City.Within the compact SUV segment, you could also consider the Hyundai Venue, which is a well-rounded package.

I really like the Skoda Kylaq 1.0 TSI AT, but I am unable to finalize my decision because of the rear seat space and a few other compromises. My other options within a ₹14 lakh budget are the Mahindra XUV 3XO RevX and the Nissan Magnite CVT. Considering these choices, which would be the best option overall? Also, what should I prioritise more in this segment - space and practicality or driving performance?

It's a shame that the Skoda Kylaq's rear seat space is not quite up to the best in the segment, because otherwise it is a superb compact SUV that scores highly on most other counts. Of the other options, the Nissan Magnite, while capable and a great value for money, feels like a sub-segment lower in terms of quality, space and performance. The Mahindra XUV 3XO RevX should be your best bet because it offers both - performance and rear-seat space. In fact, it has one of the most spacious cabins in the segment, although the boot is a bit smaller than others. The RevX offers a good feature set as well, along with a few unique styling embellishments, and overall, we feel this is the one you should pick.

Hi, I currently drive a 2015 Honda Jazz diesel with 200,000km on the odometer . I have got the best in everything from the same. Most of my travel is in Pune city, where I clock around 100 km per day, and once a month, I travel 1000 km outstation. So in total, around 3000 km approximately in a month. My budget is ₹15 to ₹18 lakh, but I need a better 5-seater SUV and expect a strong balance of mileage, power and style. Kindly suggest, as I am a big fan of diesel cars.

The Kia Syros HTX+ 1.5 diesel-AT is an excellent, versatile compact SUV that's spacious and feature-rich. It offers exceptional cabin space and gives you the flexibility to expand boot space to carry more cargo, should you need. The diesel-automatic combination is smooth, refined and efficient too. Yes, its styling might not be to everyone's taste, but if you like the way it looks, this is the one to go for.Other diesel-automatic options in that price bracket that you could consider are the Hyundai Venue and Kia Sonet, both of which share their diesel-automatic powertrain.The Mahindra XUV 3XO is also a good, spacious option, and while its engine is very powerful, its AMT gearbox isn't as smooth as the torque converters that rivals offer. Even the Tata Nexon gets a diesel-AMT option, although it isn't as refined as the others.
