Hi all, I asked this in the intro's but maybe better here.

I think the injectors need a cleaning on my 03, the dealer is going to do it next week. I just picked up the truck last week, so they say it'll be no charge.

He suggested adding some cleaner (stanadyne) to the fuel in the meantime. Couldn't find that but I've got a liter of the Howe's meaner cleaner. How much and how often should I add it to a full tank. I put in about 1/4 L this morning.

Great site by the way, its helped me out lots for my 93 truck.

 

Why not follow the directions on the Howes bottle?

 

I use 6 ounces of Howells and 6 ounces of Power Service (Gray bottle) every tank full. Makes my truck run quieter and smoother.

 

I think for the Howes it is 1 oz for every 4 gallons. I don't have the conversion tables handy but I figure you are close? I run Howes in the Ford and Stanadyne in the Cummins. Really, no improvement on mileage, just peace of mind.
