I have 250 miles on my Lexus IS300. Does anyone have any particular advice on a solid additive to add to the car, IF ANY, on my next gas fill up? I heard there are special additives formulated for new cars to extend the life of the valves, and so on which you can initially add on your first fill up. Thanks alot.

Personally, I don't think modern engines need this at all. Scheduled oil changes, periodic valve adjustments, and timing belt changes as needed should protect your valve train for the life of the car.
Mostly top oil was used in older engines, where upper engine lubrication systems weren't the best, and valve guide wear was pretty common.
However, after saying all that, certainly there's no harm in using it and perhaps in adverse conditions it might actually do something...hard to say...
I'm a little leary about using this stuff in newer cars as I'm afraid they might clog the injectors. While Marvel Mystery Oil has come out with newer formulas for fuel-injected cars, their heyday was back when carburetors were the norm.
Now, I only use a little Redline SI-1 fuel system cleaner and some isopropyl dry gas in my cars.

I believe it had something to do with lubricating the upper cylinder walls and allowing the rings to seal more effectively.

brorjace: I also saw about 1 mpg improvement with MM. I'm with you about using it anymore though.

The use of MMO consistently took my car's light oil usage and turned it into ZERO oil usage.
