Using high quality fuel for years will reduce the carbon build-up.
You also reduce detonation and other things.
I cannot remember the last time I used 98 RON in my vehicle.
For the past 4 years I have only used 102 ARAL or 102 Shell V Power.
In my book the 70 EUR I pay extra a year more expensive petrol is worth it.
For the fun of it, 15000 km ago I used Chevron Techtron Concentrate Plus.
I also clean my injectors every second revision and with my latest headgasket surgery, my mechanic was pleasantly surprised to see the state of the engine. He made everything mint again when fixing the vehicle.
