98 Octane?
Is the higher the octane rating, the better? Here in Europe they sell 98 octane. Is this okay in a daily driver with the mods I have? TIA.

Baddgene,
I think that the fuel we get over in Europe is 98 RON, not 98 octane.
RON stands for 'Research Octane Number', and a 98 RON fuel is less volatile/resistant to detonation, than a 98 octane fuel.
For what it's worth, I believe that the octane rating given to fuel in the US is calculated by adding the RON and the MON of a fuel and dividing by 2 (i.e. the average of the two). The MON, the 'Motor Octane Number' is the better measure of a fuel's resistance to detonation (under load), and is on average 10 points lower than the RON.
Therefore, 93 octane in the States offers similar knock resistance to the 98 RON fuel available over here.
I would say that you should NOT put anything (i.e., anything available on the forecourts) but 98 RON in your L. Anything less is begging for det.
BTW, hello everyone from the UK. I just picked up a 2004 L in black and am in love. Having just sold a 517hp RX7 that lunched 2 motors in 1,500 miles, however, I will not be modifying the L. At all. Much...

Hello guys,
Nice to be part of such a helpful community. Glad I could help.
As for modding the L, well being over here in the UK means that it's very difficult to get hold of parts. If I could get hold of a 'kit' that boosted hp, then I'd be interested (don't Moroso do something like this?), as I simply don't have the access to the dealer network that most of you have...
Having said that, I'm really (justifiably) concerned to ensure a safe tune. I've seen too many people p1ss1ng into the wind when it comes to improving their times. There is no way I'd ever tune a motor without getting the truck on the rolling road for some proper data. Thing is, if the a/fs aren't safe - what can I do about it...?
Thanks,
Joel
