I faced a strange issue which I have never seen in the past 7 ½ years of my ownership with Vento TDI 1.6 2014.

My experience with Xtra green diesel
I filled Xtra green diesel at KR Puram IOCL COCO a month back, there was some improvement in pickup but nothing magical to report out. However, I faced a strange issue which I have never seen in the past 7 ½ years of my ownership with Vento TDI 1.6 2014.
We went on a joy ride for about 200Km round trip and reached home around 7:30PM. I was about to turn off the ignition, but I noticed a sudden raise in RPM from 800 to 1000 at Idle, I thought I accidently pressed the accelerator, but my feet are on the floor. I turned off the engine and cranked again within a minute, I see the Idle RPM is normal again, not sure what happened and ignored as a one-off issue.
A week later, I once again filled Xtra green and went on a Joy ride for about 300km round trip, the same issue happened while I was about to get out of the car after reaching home, I shut off the engine and cranked again, saw the Idle RPM is back to normal reading at 800.
I narrated the incident to one my close relative, he is in automobile field. The first question he asked was whether I used any additives recently, I told him about Xtra green. He says this might happen due to the cleaning agent doing its work, but I don’t want to see this issue again. So, I filled regular diesel from the same pump and went on a long drive and driven within city covering around 500km, until now I did not see the issue.
I have used Shell V power diesel continuously for two years prior to Covid and tried 3M diesel additives on couple of occasions but I have never experienced this issue before.
Is it due to slightly higher cetane rating in Xtra green Diesel? I’m not very sure.
If you have faced similar issues or anything specific to VAG TDI, welcome to share your thoughts. Drive safe and stay safe.
Here’s what BHPian el lobo 6061 had to say on the matter:
This is because VW 1.6 TDi is NOT Compatible with B7 Diesel XtraGreen.
I had forewarned people to 1st read their car manual to understand whether their engines are compatible with B7 Diesel and then only fill it.
Here is what my Vento 1.6 TDi manual says
VW Manual says (Not compatible with B7 Diesel)
“Failure to observe this point could result in damage to the fuel system and engine damage!”
Avoid Xtra Green for your car and be content that damage wont be significant.
My BMW X1 & Hyundai Verna 1.6 CRDI are compatible with B7 Diesel but I will still advocate to use Normal Diesel.
