Speak to Lexus, tell them where you are taking your car, and ask them if suitable gas is available - they will know.

I see you are using nitrous in your car - I don't know what you want to achieve but nitrous and cheap gas aren't going to work very well for any intended application.

And, out of morbid curiosity, where are you taking the car?
looks like noone actully knows for sure if I can or I cant.

I have to ask the dealership I guess

Iam send it to Yemen... some far far far way country you might never heard of

Sure we do, but you need to figure out how octane is assessed in Yemen and what "83 octane" means:

$10,000 fine for that.

Only places you really see still using leaded gasoline is the middle east, eastern europe, some parts of asia, and parts of south america.
You can buy 100-110 octane leaded race gas at select gas stations. Perfectly legal. A lot of the 1000hp supra guys use it.

Not for street use, no you can't.

They DO sell leaded race gas at some gas stations and tracks and such. For use off-road.

Using leaded gasoline on public roads is up to a $10,000 fine.

http://en.wikipedia.org/wiki/Gasoline

"Possession and use of leaded gasoline in a regular on-road vehicle now carries a maximum $10,000 fine in the US. However, fuel containing lead may continue to be sold for off-road uses, including aircraft, racing cars, farm equipment, and marine engines.["

http://www.epa.gov/history/topics/lead/02.htm

"Effective January 1, 1996, the Clean Air Act banned the sale of the small amount of leaded fuel that was still available in some parts of the country for use in on-road vehicles. EPA said fuel containing lead may continue to be sold for off-road uses, including aircraft, racing cars, farm equipment, and marine engines."

You -can- use it. As Chris Rock once said, you can drive a car with your feet if you want to, it doesn't make it a good idea.

Have you heard of people being fined $10,000 for using leaded race gas on the streets? Yes, it is illegal, but I highly doubt people get pulled over for using race gas. I can see it maybe happening in ****-CA, but not anywhere else since the proper emissions equipment is necessary to detect leaded gas.

The law is pointless, as these cars will be driving on the earth at some point. What does it matter if it is on the street or at a race track?

There is a reason why there isn't a law against gas stations selling leaded gas. Or else it would only be sold at the track.
