Nothing.... I run MMO from time to time if I need to.

[BiggyC]

I put Stabil during my last fillup before the 4.5 month winter hibernation. I'll run the car a good 20 miles or so before it goes down for the winter. Other than that, nothing.

I get my fuel injected cars Motorvac'd every 60K. Will probably get the Carbed 02' done as well.

One gallon of Phillips 110 octane leaded per eleven gallons of ninety-three octane unleaded non-gasahol. Runs like a raped ape.

I've been using Lucas' 'Ethanol conditioner'. Green liquid, small dose/tank. No idea if it is doing anything but it feels good.

[JohnS]

I use the TECHRON Fuel Injection cleaner about twice a year in all of my cars.

[flyingjolly]

do some of you guys use lead substitution?

[Mike Self]

They have hardened, pressend in steel valve seats, and the lead content of gas was primarily to prevent valve seat erosion in engines with cast iron cylinder heads that weren't induction hardened in the valve seat area, which was about every US car built prior to the early-mid 70s.

Cars with aluminum cylinder heads use hardened steel inserts for valve seats, so no problem.

High performance engines, and those under heavy loads were particularly susceptible to valve seat erosion with unleaded gas, unless the valve seats were hardened steel.

Scotch.

Edit- Oh. You mean adding to the fuel tank. Nothing.
