Is this a joke? Using higher than needed octane will NOT increase combustion temperatures. There is effectively the same about of energy per liter of fuel regardless of octance number. If your combustion temperatures are above normal, you're running lean. If you've got blue smoke coming out the pipe then you are burning oil somehow... which means your head gasket is probably leaking or your piston rings are shot. ←

I would like to know if you can use E85 - 85% alcohol?

Just last week a Lexus dealer did a warranty upgrade on my lexus link as a result of a letter from Lexus. Maintenance rep at dealer says he doesn't believe it is available anymore and is useless. What is the true story on this - is there a new link system or not. If not seems dumb that they would have reprogramed so that when I start the car it tells me to push one of the buttons to activate the system! Just bought vehicle from an Acura dealer last month. 2002 LS420, also can I update my nav system with a 2005 landcruiser cd?
