So you carry the 80oz jug around with you? How are you transferring it from the jug to the tank?


I bought a 16oz bottle of Sta-Bil (perfect size bottle to fit in the rear driver’s side door pocket so that I pull up to the pump, open the door, and pull out the bottle) that has a tip and measure feature built in, dumped the Sta-Bil, and use just the bottle for my additives. Works great! Just wish someone sold empty bottles like this, but I tend to have stores of gas in the garage in case of hurricane, so I just use the stabil in there.

I keep it at home and fill up empty water bottles I’ve dried out and take them to the pump with me each time I fill up, but mines not my DD so a fill up might be every other week or once a month depending on use but when I’m towing and we’re gonna for a long weeken I will take the jug and empty bottles with me or prefill bottles before the trip, I also run Diesel Kleen
This is my method as well. I read a while back that leaving the additive in a water bottle for a duration will somehow leach something (can't remember what) from the bottle so I fill the bottle right before heading to the fuel station. Anyone else heard of the additive leaching something from a water bottle?

That’s cool. I have no doubt that a fuel additive is warranted. What I wonder about is the differences between the different additives. My guess is they’re all pretty much the same and it boils down to personal preference, but I’m no chemist.
If my memory services in your case I would not use any fuel additives for a while. You had gelling and strange red junk and were using 3x the normal amount of stuff in an earlier thread right?

Don't use any additive for a while and then start adding the recommended amount and check again etc.

I have been looking for that thread to update my analysis of the gunk on your primary fuel filter.

have you ever accidentally put DEF in your tank? See attached and look at figure 11

Yes, that’s me. I still haven’t even gotten my truck back from the dealer. They’re replacing my torque converter [emoji51]

No, never a drop of DEF in the tank. Unless someone at the dealer or someone at my independent shop has done it on the sly without me knowing.
 
I use Optilube XPD in every tank, ever since my HPFP went out at 150,000 miles. Optilube XPD has superior lubricity per independent tests. The links and copies of these tests are on Optilube’s website, as well as in another thread—where I initially learned about Optilube. I buy it a gallon at a time on Amazon for $70 delivered. Not cheap, but neither was a $10k replacement of my fuel system. I get better fuel mileage and performance with it, and the peace of mind that my pump is not going to grenade again. Optilube also sells a spout with a lid that mounts on the gallon container, which can be bought on their website or on amazon. It makes it easy for storing in my toolbox and squirting some in my tank at every fill up. I just guesstimate re the amount, and err on the side of more is better. I bet this HPFP will last 500k with this practice. But I’m an optimist 😉
 
I use Rev-x diesel fuel additive and use 1oz per 12 gals. I tried using .5oz per 12 gals and got a Low fuel pressure warning. Instructions say .5oz/12galsfor normal use and 1oz/12gals for performance.
 
What brought this up was a buddy came by the shop and noticed the destroyed HPFP pump and worried that his may be going out. As a preventitive measure he asked that I change his out. He religiously uses a fuel additive. Pulled his HPFP and it looked brand new and I put back in his truck and saved him $500 on a new pump.

What’s the going rate to pull and inspect a working pump?


I was using walmart 2 stroke in my 6.7, but noticed it started blowing a puff of black smoke at takeoff do I switched over to the motorcraft PM-22 stuff, and will be switching to DK soon.

I still have 2 gallons of the 2 stroke oil in the garage- I wonder if slipping less of it per tank (than I was- was 16oz per tank) would hurt anything.

450-800 depending on your location

I've been using Opti-Lube Summer Plus since the truck was new. Almost the same lubricity as XPD but more cetane and no anti-gel and much cheaper per use. When I need anti-gel, I use Opti-Lube Winter. I carry a gallon jug of Summer Plus in the basement of my fiver for refilling the 16oz bottle in my passenger door pocket.

Q1: Did you use an additive prioir to the HPFP grenading?

PS: CPT Obvious quote... Be careful of marketing hype, for instance, CAI's add horsepower and are better for your OEM/tuned diesel. :doh::rofl:
 
I never used an additive prior to my HPFP grenading at 150k. Expensive lesson. Interestingly, I had just deleted and tuned with H&M on tow tune within the last 15k miles, but my local shop didn’t think this had anything to do with it. I trust these guys, as they’re all ASE ex-Ford guys. It’s Burleson’s in Hernando, MS. They’re really good.

I don’t know what you mean by the PS, if it was directed at me, or what CPT is. I wasn’t quoting anybody or marketing for anybody if that’s what’s implied. I researched the lubricity issue after the grenading HPFP event, and came away convinced that Optilube products are superior. Once in a while if I run out and before my new order comes, I will put some Diesel Kleen or Howes in there, but I trust the Optilube based on the lubricity tests I read.
 
Pretty religious user of Optilube XPD here. No FP issues so far at 100k+

150-200k seems to be the window for HPFP failure in my experience.
