Indian Oil Corporation [IOC] — Poor petrol quality

Address:

Post-shree mayapur, dist-Nadia, Gournagar, WB,741313

Hi,
It's been from long time I was trying to find Indian oil complain site.
This complain is about petrol quality, I have some understanding after I used many petrol pumps that the petrol station in our area has bad quality petrol (something mixed with petrol).
The smell of the product is very unidentified.
When ever I/we get filled up petrol from this pump our engine sounds gets so unhealthy and the vehicle performance downgrades alot.
My request is please make a random quality check in this petrol pump . Also check if they are providing the right quantity..

(Petrol pump name -Jyoti Petroleum and Agro Services
