Etanol fuel

[EuroDude]

Why are E10 95 RON fuels below the actual 95 RON rating? If they were, they wouldn't be labelled 95 RON.

Why waste your time mixing half and half? Just go full 98 or full non-ethanol 95.

BTW, check out the Sydney Euro meet thread in Upcoming events.

From the Mobil site:
"The octane in Mobil E10 Unleaded is typically above 93 RON"

The Euro engine needs at least 95RON.

Why do I mix?

- to ensure the fuel is at least 95RON
- the car runs smooth on ethanol
- the cleaning agents in 98RON are better than 95RON
- Overall cheaper than plain 95RON

Go use BP's 95 RON ethanol blend. That is advertised as a 95 RON.
