Trying out XtraGreen diesel from IOCL in my 50,000 km run Tata Altroz

It is about Rs 3.5 costlier than the normal diesel & after using it in the Atlroz, I'm planning to use it in my Safari Storme too.

50,000 km Update - Tyre replacement, Xtragreen Diesel Experience

The Little Tata has completed 50,000 km, exactly in 19 months since purchase. Well, running in is officially over.

Tyre replacement

I decided to replace the stock Goodyear assurance 185/60 R16 tyres. They still have about 5000 km of life left. But I don't want to risk it given the high highway speeds I regularly do.

I tried sourcing Michelin Primacy 4ST which I loved in my Ciaz - very silent and comfortable tyres. Unfortunately, Michelin tyres are very rare to find below the size 17 inch.

Next options were MRF perfinza (recommended by Dr.Naren) and Continental UC6. I have already used Continental MC5s on my Ciaz and loved the grip. But the tyres got noisy after 20k km. I also read Perfinzas are noisier than the UC6. I decided to go ahead with UC6.

Slow speed stiff ride on bad roads is one negative of Altroz that I want to change. Hence, decided to upsize the sidewall height by a little

Stock 185/60 R16 vs 195/60 R16

There is about a 13 mm increase in the sidewall which will aid in making ride quality softer. I will have to compromise a little on handling though.

The new tyres were April 2023 manufactured ones. Costed me 8.8k per tyre.

15th week of 2023 manufactured

Old vs New

I can't comment on tyre performance as I have just driven 100 km with the new tyres. As of now, they are quiet in comparison to noisy goodyears, ride has become more cushy and handling has gone one notch down. But I knew that when I decided to give priority to ride quality.

Experimenting with Xtragreen Diesel from IOCL

I am no fan of trying out additives in fuel. But I heard Xtragreen is not additives added diesel like xtrapremium diesel, but has a higher Cetane number (Normal diesel 51 vs Xtragreen 55). Also, the engine refinement and fuel efficiency get improved. Luckily, IOCL near one of my offices has Xtragreen dispenser.

Xtragreen diesel is about 3.5 rupees costlier than normal diesel. I discussed this with my friend and fellow BHPian Sanjeev, who is an expert in ic engines and works for a reputed automobile manufacturer. He explained to me that B7 diesel can be used in BS6 cars without any issues.

I have driven about 1000 km with Xtragreen over 4 tank refills. I can surely say there is a tangible reduction in engine NVH. Fuel efficiency has gone up by 1 kmpl. Definitely worth the extra cost in my opinion. I am planning to use the same for my Storme too.

Here are the fuel efficiency figures with Xtragreen

I also bought a new (used) bus for one of my schools. After getting bummed out by the new Bs6 school bus prices, I went to the pre-owned route. Took me a lot of weeks of traveling and seeing totally useless, abused samples before ending up with a very low run (36k km) 2018 SML school bus, 6 km from my location lol. It was quoted 13L which I managed to bring down to 11.5L, that's 50% of a new bus' cost. Loved how car-like it was to drive and how refined the engine was(by bus standards). This is the 3rd consecutive SML bus I have bought in the last 3 years.

A few pics

Storme will also be joining my garage as a secondary ride. Planning to use both the Tatas equally. Storme was out of action for 20 days this month, and hence Altroz was used over 3000 km in June. More info here.

Both Tatas have brand new tyres now
