Re: Fuel / RON ?

I use it in the MR2 tub and the T5 when I can't get to Tesco. But neither car seems able to tell Tesco 99 from V Power.

Re: Fuel / RON ?

Its weird that manual only mentions RON 95. Previous cars manuals said 95, and optionally 98.
Usually you hear that 98 is only needed for high performance cars (read, with turbochargers). Shouldn't make a difference in power at all. In theory

In reality modern cars run at compression over 10, which once was unobtainable without high octance fuels.

My dad pointed out that car feels smoother with 98, especially accelerating from low revs. The difference is there, but not apparent after first fillup. I guess ECU adjusts itself gradually
Price difference between 95 and 98 here is 3.5%
