Re: fuel additive
OK folks I've learned of this stuff:
Lubro Molly inj cleaner, and
Lubro Molly valve cleaner
4th and 1st items on this page (for example):

Anyway, I've run this stuff through all three of my vech. '97 Avalon, the Sy and my '86 325 Bimmer. Maybe some improvement but hard to tell, EXCEPT the Bimmer. Now we're talking 20 year old car with 210k miles. It made a VERY noticeable difference. I was surprised. Most of the time you pour something in and the only thing that changes is the weight of your wallet. This stuff worked on that car. Smother idle, better throttle response, measurable better mileage. (Even that old Bimmer has a mileage computer!)
Take it or leave it but I'm sold, at least with what it did to that car.
