Rotella DFA fuel additive

Anonymous Poster · Oct 16, 2002

Hi,

I was using fuel at such a rate that I over bought and will have at least 10 gallons and a full tank when I put the tractor to bed this year for the first time.

In Pittsburgh, the coldest I have ever seen it was around -20 F. But this is really rare. For the last few years I am not sure we went below 0 F. even once. Mabye we did, but not frequently. But -20 can happen too...if only for a couple nights.

I got some Shell Rotella RFA deisel fuel additive. It says 32 ounces is good for 100 gallons... which is about 1.6 oz per five gallons. I added about 3.5 oz per five gallons.

But I wonder...is 3.5 oz per five gallons too much? Too little? Or just right?

"Treats up to..." in my mind always means " use more than..."

How much should really be used per five gallons?

Anyone know?

Any input greatly appreciated! I want to be able to play.../w3tcompact/icons/hmm.gif ... I mean work in the snow if we get any...

My understanding is that it won't hurt it.

I did the same as you; added a generous helping to my fuel tank - more than what the label required. My guess is that the label guidelines are a minimum.

I also add it to the two diesel fuel containers I have.

My guess was:
More is better than not enough.
The dilution of the stuff is such a small ration, that the engine would experience no difference between 2 and 6 ounces (assuming a 5 gallon tank).
Therefore, using too little could certainly allow the fuel to gel, so why take a chance?

I’m in Butler,… where are you?

Hi Rogue,

I'm off I79 at Mt Nebo...

Tried to reply off line to the hotmail address in your profile, but it did not work...

I used about 5 oz per five gallons. I have a couple extra five gallon containers of fuel, as last time I went to the off road place, I bought too much...had got into the habit as I put 120 hours on my B2910 in the first two months, and I must have thought that was going to go on forever, regardless of weather changes or other things like promises to the wife /w3tcompact/icons/love.gif/w3tcompact/icons/shocked.gif/w3tcompact/icons/frown.gif
