Hate to burst everyone's bubble, but it's a fact that Toyota & Honda build in an apprx 5% margin of error in their speedometers. So an indicated speed of 100mph on the speedo is actually 95, 145 is really 137 and so on. Don't know about the rest of you, but I don't plan on hitting the engine limiter on my GS...

I have a GS450h (Jun07) and with 100-Octane Fuel I reached beyond the last reading of the tachometer, approximately 280km/h (or 174 miles per hour), whem the limiter kicked in. The car was AMAZINGLY stable, quiet and comfortable, the brakes were a breeze, I just hate the speed limiter!
Howerver, I think that the 280Km/h reading was a bit overstated since, if we deduct the 10%-usual-overstatement by all car manufacturers it most probably corresponds to the purported 250Km/h REAL speed that Lexus decided to electronically limit the car.

Hello there ste.
100 Octane fuel is available in few European Countries. I 'm not sure about the US.
Some background reading: http://en.wikipedia.org/wiki/Octane_rating
I live in Greece and we have BP Ultimate 100, Shell V-Power Racing 100, and some local brands of this fuel (like EKO, etc). The fuel does make a difference to the car's behaviour, especially as this v6 3,456cm3 engine is a big engine (at least for European Standards)...
However, as the GS is on a hybrid system that measures (and limits) output this may mean that the only difference the fuel is making is in terms of economy and responsiveness (the engine needs to burn less fuel to get the same output), as the engine may have the capability to go beyond its standard power but the KW meter won't go beyond the 250KW limit.
My limited knowledge on Car Engines indicates that using a higher-rated fuel than the Manufacturer's prescription may not hurt the engine, at least for the normal lifetime of the Engine. If you regularly "step on it" you may find that the engine needs "rectification" towards the end of its useful life (I think this is 20 years for mass-production gasoline engines). But then this is the same effect as changing air intake filters, exhausts, etc. Only that higher-rated gasoline does not require anyone tampering with your brand new Lexus!

ste - yes, Shell carries 100 oct race fuel, go to their website and they should list out all the local station that carries them. At least in CA
and you don't fill up the whole tank with 100 oct, you have to dilute them. I believe my friend used to run 70/30 (70% @ 91, and 30% @ 100) on his e46 m3.
the only down side he said was being addicted to the super expensive race gas.

Wow, you guys are crazy!
Where I live, if you go 50 km/h (30 mph) over the limit and get caught, your car gets impounded immediately for 7 days as well as a license suspension for 7 days (and potentially get the Canadian equivalent of a misdemeanor charge). Our highways have a maximum speed limit of 100 km/h (62 mph) so needless to say, when I get my GS350AWD (when they sort out the hard-start problem...) I won't be going too fast in it.
