Best FI cleaner

[santiago]

I have a '93 f150 with the 5.0l engine. Periodically I like to run FI cleaner through the brake booster vacuum line. Which cleaner would be most effective?

I have used Berryman's and Seafoam in the past.

Thanks,

santiago

I am not sure what Sea Foam does other than make smoke.

I have had the best "Seat of the pants" results with RedLine SL1. It also helped the fuel economy a little bit.

Redline SI-1, Techron, and Gumout's Regane seem to be the best bets.

You can't go wrong with Techron, get the big bottle. It has the same additive used in gasoline and concentrated to perhaps 10x when added to your tank. It helped my jeep when it was stuttering, and now it runs great.

I use E10

Gumout all in one in the gas tank

For this use, WATER.

Red Line and Chevron work well for me.

Kreen in oil and fuel.

I have never found a use for one. I say, save your money and time.

Berrymans is cheaper. Running through the booster line, you're not hitting the injectors obviously.

Methanol or water works well to clean the intake/valves.
