DEF and Fuel Additive brands

[PowerStrokin11]

Alright guys I've got about 6 months of diesel experience under my belt and loving every minute of it so far, I'm learning new things everyday thanks to this site. I've got a 2011 F250 and was wondering what brand DEF fluid and Fuel additives you guys are running. Thanks in advance

Best bet is to run nothing but ford motorcraft and keep the receipts

DEF is 33% urea and 66% distilled water. So there is not much difference between brands. You can buy Blue DEF at Wal-Mart Most truck stops have one brand or another and who knows what they pump at the pumps.

Additives is really anybodies guess. Ford says you don't need it, But they sell their versios of both the summer and winter additives.

Walmart sells Power Service. But I have found it several dollars cheaper at the farm stores. I use it in semi and tractors.

In my pickup I've been using Opti-Lube since it got such good reviews back in 2007 when one of the magazine did scar test review. But in 5 years since that test. I'm sure some of the other brands have improved.

I use the blue DEF from walmart, or any auto parts store...and use Opti Lube XPD fuel additive. Seams to be working well so far, the truck runs smoother and quieter (if you can believe that) and gained about 1mpg...lots of discussion on additives, basically comes down to preference i guess.

Stanadyne Purple.....and I live in Texas. Would be something different if I lived up north in cold country.

What are you paying for DEF? I was at a truck stop (Flying J) and they wanted $14 for 2.5 gallon jug. That's about $6/gal. I thought it was supposed to be around $2 to $3 per gal.

I pay 9-11 bucks for 2.5 gallons at autoparts store...a few weeks ago the Blue was on sale for 9, but it's usually 11...
