  1. After my first trip on the road to visit my in-laws, I realized that I took a huge gamble on getting a speeding ticket. I underestimated how smooth and fast my GS400 really is. I clocked 110 mph and the car was even breathing hard! With that in mind, does anyone have a GOOD radar detector that can be recommended? Please advise.

  2. Remember, sell fuels. If you are looking for fuel from Sunoco, the "problem" is - SUNOCO is based out of Marcus Hook, PA and they only market this product regionally. Alternatives to increase Octane would be to buy and mix an appropriate of a product like (TrackTec) or other 100 Octane Unleaded Fuels, or an appropriate amount of Octane Booster.

    Higher Octane Fuels are an insurance policy but not necessarily (or automatically and always) a performance enhancer.

    These cars are designed with a Knock Sensor which says if the engine senses knock due to higher octane demand than is available, it will !Removed! the timing of the engine. Unless the driver is extremely experienced in analyzing engine performance, he will never know the timing was retarded - because of the sophistication of the Engine Control Module. In theory, if higher octane fuel is available if and when the engines Octane Demand increases (due to heat, excess idling, car under load w/ AC in hilly terain towing a trailer), the engine would take advantage of it. To detect the difference would (probably) take some sophistecated analysis - unless the engine knocked and pinged to the point you could hear it - which will probably never happen unless you get some truly bad gas w/ water, etc.

  3. I actually sell racing fuels and octanes. I would take exception to the U.S. having the worst fuel in the world. That would be China and India. It is true though that the octane values fo fuels do tend to be higher in Europe.....

    If you have modified the engine such that it requires higher octane or Nos, then you already know you need a higher octane fuel. Otherwise, using the Fuel recommended by the manufacturer is critical to maintaining your warranty. If your warranty has expired, please continue to use the recommended fuel - with the following considerations:

    As previously discussed, pinging or clattering can result from a build up of carbon deposits - which can increase the compression ratio (and heat) in the cylinder. If the warrenty has expired and pinging starts, the engine may have had an increase in octane demand - beyond the the octane capacity of the originally recommended fuel.

    The engine needs decarbonizing or a tune up. Extended operation with pinging or clattering can (and probably will) cause engine damage over time. Service the vehicle and see if this stops the pinging. If it doesn't, go to the next higher level of octane, or try fuel from another station.

  4. I saw this new item on the Lextasy web site. Has anyone purchased these yet and if so were you pleased?

    Mr. Sypher, here's another opportunity to see if you'll do anything like this to your beautiful Lex....what do you think about these? If you'll note a lot of folks will use your car as a measuring stick to what our car SHOULD look like.

  5. The "stickers" look really good on the cars I've seen. I just wish I could see them in person. My concern is that they fade or damages the car if they are removed or start to pill off. I didn't think they were stickers, so now I may reconsider paying $60 for it (or is it for two?).

  6. Akhil, I've tried 17's and now 18's on my 1999 GS400. For whatever reason the 17's not only gave me a rough ride but also the steering vibrated. I replaced them with 18's and now I have a smooth ride with little or no vibration in the steering. I can't speak for 19's or 20's, but rest assured 18's will work for you. Hope this helps.
