As with most things.....you can order it online, in an quantity, and have it delivered to your house. When on the road, you can order online at NAPA, and many other auto parts stores and have it delivered to a store where you plan to be next week.
I would guess that any Ford dealer that sells and services their medium trucks would have it in stock.

I was just looking at this myself and the local Napa store has it for $27 for 32 oz, quite a bit more than Dot 3. Being synthetic I'm not sure if it absorbs less water than Dot 3 or can go longer between fluid changes.

When I changed out the 20 year old brake fluid in my 1994 Holiday Rambler I switched to DOT 5.1. Yes I had to order it, in fact the so called "parts professional" didn't even know what it was or that his store (O'Reilly) carried it. I had to look it up on their website and then give my PP the number so he could order it into the store for me. I guess there's not much call for hi-temperature brake fluid in the Texas flatlands.

BTW, driving my rig around the Rocky's, Sierra Nevada's, Cascade's and Olympic Mountains I'm sure glad I have it!

Some motorcycle dealers carry it (not Harley, Harley's use DOT 5) but you'll pay dearly for it at a motorcycle dealer.

5.1 is a synthetic. My Harley uses DOT 5...and is not to be used or mixed with Dot 3...or disaster.

And just to make it more confusing, DOT 5 and DOT 5.1 cannot be mixed either. DOT 3, 4, and 5.1 are all polyethylene glycol based, while DOT 5 is silicone based. DOT 3 and 4 have lower boiling points than DOT 5 and 5.1.

Or have Napa, AutoZone, Or o'reilly order it and it should be there in a couple days.

What does that dealer use? You would think that would be a required item to stock.

Thanks Fred, I;ll try the dealer again
