Thank you Shane - based on that I will start to try it. Do you think it is OK to add HVO to a half tank of diesel already in car? Hi Conor, In theory there's no reason whatsoever to not use HVO in any diesel car, even though not all car makers have officially approved it. Shane O'DonoghueAnswered by Shane O'Donoghue 10.07.2024
Hi Conor,
There's no issue with adding it to traditional diesel in a tank as it's chemically identical.
