Post up and complete the following if you KNOW FOR SURE the octane ratings of a brand of fuel.

Esso Super Unleaded 98 Ron
BP Ultimate 97 Ron
Shell VPower 99 Ron (some sources say 98)
Tesco Super Unleaded 99 Ron
Texaco
Morrisons
Jet

 

[SLEEPER]

Tesco 99 is now called momentum

I know for absolute certainlty that it is 99 octane as I wrote and asked Tesco to confirm it in writing when they changed the name as my car is specifically mapped for 99 ron.

V-Power is 99RON. Its predecessor, Optimax, was 98 RON.
