diesel fuel supplement + cetane boost

[brandan250]

just got a 2004 f250 6.0 looking for better fuel mileage just wondering if power services diesel fuel supplement + cetane boost is worth it?

Nope. It doesn't really add any MPGs but may help the injectors by keeping them clean. Just try it per the bottle directions and see what happens. You can try adding TCW3 2-stroke oil at 1oz per gallon of fuel as well.

Best bet is to track your MPGs till the summer when they switch the fuel formulas. Do the same thing over the summer.

that power service is good at preventing gelling but will actually bring your mileage down. i used the stuff they sell at ford that is from powerstroke in my 6.0 and my mpgs went up a little. Didn't notice a big difference but at least it didn't go down.

I think the gray bottle (Diesel Kleen + Cetane) helps some but the white sure doesn't.

I use both the grey bottle of Diesel Kleen and Valvoline 2-Cycle at every fill-up. Since I started, I've noticed the injectors aren't as noisy, and had a slight power & fuel economy increase. Getting the lubricity back in the fuel system is the most important part. ULSD (Diesel #2), has pretty much deleted all lubricating factors due to the tree hugging, global warming, EPA liberals.

The white bottle of Diesel Kleen is just for use in the winter. It keeps the fuel from gelling, but it will lower your fuel economy. Unless your winter temps drop below 20* on a regular basis, I wouldn't use the white bottle.

I also run 2 stoke oil with every fill up, but my additive of choice is howell's. I use it in our big rigs, so we buy it in bulk at the local TAG truck center, at $9 bucks a bottle that treats 320 gallons it last a while.
