Engine knocking isn’t a rumour, it’s true. However Honda Atlas has remapped the ECU which has fixed the issue for now but I still use RON97 Total Excelium.
Depending on your driving destinations and which city you live in, you should be able to make a better decision if you should buy a turbo or not. It definitely IS NOT a start 1,2,3 go car. Needs a lot of care if you want it to last.
To be on the safe side Oriel is perfect.
