Re: Taller 5th gear ratio for better fuel efficiency & top end speed That is one good looking Esteem.
I had a BS3 Esteem from 2008 to 2018. The maximum fuel efficiency I got with the tankful to tankful method was 23 kmpl in an Ambala to Delhi border solo run in peak winters and the heater on. The odo read about 58000 km at the time. The next highest was 20 kmpl in Goa to Pune run with family and AC on at all times. Tyre pressure was maintained as per manufacturer recommendation. I had similar figures on the on my other highway runs.
I now have a Ciaz AT which returned 20 kmpl in a Shirdi to Pune run. The tank was filled up at a Reliance pump on the outskirts of Shirdi and refilled at BPCL pump in the city.
The only thing common was that I was driving in my comfort zone of speeds of 80 - 90 kmph.
We still have a 95 Esteem in the family which has the best driveability among all the cars. It is not frugal but the gear ratios are well matched. I needed to really work the gears in the BS3 Esteem due to the tall gearing.
My take: you are getting a very good average. Please do not tinker with it - you may lose out on the driveability.
I would also suggest you maintain the recommended tyre pressure (26 ??) instead of 32. Oh, and do check the distributor if has been advanced. Advanced is more fun but less efficient. I do not recall if it had a vaccuum advance system. |
