I run redline 85+. Half bottle per fill up. I've used redline since I had my 2006. 2014 and now my 2019

 

Everyone! Ultra low sulfur diesel! Every tank! Optilube!

 

Everyone! Ultra low sulfur diesel! Every tank!

Casper, WY ... was just there last week for work. Also lived there from 2006 to 2011.

Met my wife a couple years after I left Casper ... and she asked me one day why I always park facing west.

Only somebody from Casper would know exactly why I park facing west ... before I say what I am about to say.

Cost me $1100 to fix my driver’s door from parking east when I lost my grip exiting the truck. :wink2:

 

Power Service Diesel Fuel Supplement + Cetane Boost in the colder months ... winterizer/antigel that is used in the cold winter months to prevent fuel gelling and keep fuel-filters from plugging with ice and wax. When temperatures drop, paraffin (wax) in ULSD fuel will gel stopping fuel from flowing through the engine, and water in the fuel can freeze on the facings of fuel-filters, blocking fuel flow. Contains Slickdiesel® Lubricator to protect fuel pumps and injectors from increased wear caused by poor quality Ultra Low Sulfur Diesel (ULSD) fuel.

Power Service Diesel Kleen +Cetane Boost in the warmer months ... total injector cleaner and performance improver that cleans injectors, boosts cetane and lubricates fuel injection components. Contains Slickdiesel® Lubricator to protect fuel pumps and injectors from increased wear caused by poor quality Ultra Low Sulfur Diesel (ULSD) fuel.

Slickdiesel Lubricator is a proprietary Power Service diesel fuel lubricity additive that is added to many of our products to increase the lubrication properties of diesel fuel. This increase in lubricity will increase the life of fuel pumps and injectors. The fuel pump manufacturers (Bosch, Delphi, Denso, Siemens and Stanadyne) consider fuel lubricity to be the most crucial property of diesel fuel as it relates to reduction of pump and injector wear. The Engine Manufacturer Association (EMA) has stated that, “Shortened life of engine components such as fuel injection pumps and unit injectors usually can be ascribed to a lack of fuel lubricity and hence is a concern to engine manufacturers.” Slickdiesel Lubricator meets the new ASTM HFRR 520 Lubricity Specifications for the United States and the more stringent European Specification of 460 in most fuels.

I run these additives in every tank ... because of ULSD and the problems it causes ... and I do not trust my regional refineries to always provide quality diesel fuels (work experience in these facilities).

 

I've ran around 40,000 miles with Standyne in the summer, and then Standyne + Diesel Kleen bottle in the colder months. A couple thousand miles ago, I switched out the Standyne for some Optilube. It's cheaper for me in the long run, that's why I made the switch. I mix the summer blend and the lubricity blend together, and only use 1oz total per 10 gallons. No issues since the switch so far.

 

I add some Power Service anti-gel when it is very cold for added insurance but it may not be necessary. I was talking with my propane supplier last year and they along with several other large fleet owners settled on using diesel from Casey's convenience stores after doing extensive testing and finding it was always suitable for well below the coldest temperature in this area with no additives and that is running in a wide range of trucks through semi and medium duties down to pickups from all three U.S. manufacturers. The only time I had a gelling incident in my 2006 was using the more expensive diesel from Shell. Given that some people have experienced gelling with the L5P fuel setup I will continue to use Power Service in the cold weather.

The L5P fuel filter is definitely more convenient to change than my previous Duramax diesels but one thing GM did get right with the old 6.5 diesel was the fuel filter location. It sat in the V of the engine which helped keep it warm and it was very easy to change with excellent access.

I always sort of looked down on convenience store fuel before but the Casey's diesel seems excellent and now they have ethanol free premium so my Corvette may be drinking some of that this summer. I will add some Chevron Techron to the premium gas I buy there since that is the primary additive for the "Top Tier" fuel designation and although it does nothing to clean the intake valves on direct injection gas engines it does still help keep the rest of the fuel system clean.

 

No additives ever.

But I don't by fuel from discounters either, since one of the reasons they can be cheaper is to not include an appropriate additive package in the fuel.

 

Stanadyne is the best!
.02c

 

Is this thread directed toward L5P only (I assume yes)? I run no additives as of yet, but I'm interested in what others are running for the L5P. I believe the manual says not to run additives, as did my dealer.

 

Power services in the white bottle with a red cap that they can't seem to figure out a design that doesn't leak. Put a few glugs in every tank during this cold weather.

 

I run Optilube XPD with every tank

 

stanadyne or similar every tank or every other tank because i like moving parts to stay moving. I would not recommend adding oils like on the older trucks though, things like 2 stroke, ATF (which is a bad idea anyway) or similar. i could see those causing soot accumulation to increase rapidly.

edit, i have seen good things about optilube by several people, but its hard to get here so i have not tried it.

 

I am not sure what I should get. I am looking for something that I can pickup at the local auto parts store - I just didn't want to risk getting something that will hurt things or doesn't work. My goal is two fold - I want something that cleans/lubes the injectors, and I want something that also gets into the DPF that will help clean it out (reduce the amount of DEF cycles).
This trucks fuel filter was done at 16k miles, and was not as black as the many others I have seen around the web. I have also experienced a fuel mileage decrease of around 2mpg, and increased DEF cycling. The root of my fuel mpg drop is purely due to DEF cycles, so I would like to minimize those as best I can.

 

if you are looking for a highly rated additive, with the caveat that it is easily available at any parts store, stanadyne is probably your best bet. It is highly regarded as the best by many users, and i have never seen a parts store that didn't have it on the shelf in at least 2 sizes. It also meets your lube and cleaning needs, though im not sure if it would make any difference in your DPF accumulation. There are other additives out there that are equally well liked, but they are not as available, like optilube and similar products.

 

I don't know of anything available at the auto parts store, at least around in my area. That's why I originally went with Standyne, it's available at TSC. Now I am running the two different Optilube products, since buying them in a larger quantity is cheaper for me in the long run. So far I have not noticed any increased regens. Maybe some of the diesel you're buying is causing your truck to regen more? I am not sure if that is a thing or not. Mine is pretty consistent with the MPG's, and I also only regen once per tank of fuel.

I don't have a L5P but in my LML I use OptiLube XPD during the spring, summer and fall and I use their Winter formula in the winter. I use it in hopes the added lubricity will help out my CP4 and I also use it to help try to keep my injectors cleaner.

 

Amsoil Diesel Injector Clean + Cetane Boost. Good mileage and lubrication, plus peace of mind.

 

I went ahead with the Lucas Deep Clean product. I will let you know how it works out.

 

This stuff? that says to add it to gasoline and that it contains no harmful or useless diesel or kerosene fuel?

 

No, this stuff

 

ok just checking, they dont have the diesel flavor here so i assume its less common to find and i had remembered reading that bottle in the past and seeing that it did not appear to be designed for diesels.

 

I ran Optilube XPD until I came to realize I was simply helping out the next owner

 

weird, i used to not put sand in my gas tank, but then i realized i was just helping the next owner.

 

Standyne in mine. Bought it at 50k now 120k no injector problems. By it on line.

 

I run Total Power FPPF because John at Kennedy Diesel said it’s good stuff. Used close to a case of 32 oz bottles over the past 40k miles. Truck seems to like it. No gelling at neg temps. Plus little lube always helps right? Talking about injectors. 😲

 

Power Service user here... white bottle in the winter, grey bottle in the summer. I also add a bit of ashless 2-stroke motor oil (typically marine engine oil) to each tank as well. I recently had my injector balance rates checked, at 131,000 (they are the originals), and got a positive report back from the technician. Although they forgot to give me the report when I picked up the truck.

 

I will let everyone know how this Lucas product turns out. I will be adding it tomorrow (to 25 gallons) when I get some new fuel in it. I am hoping that my regen cycles get much more distance between them.

 

I've been using Power Service, 6 oz every tank. But I've been considering Hot Shot's Secret. Does anyone know anything about them?

 

ttt

My buddy switched over to Hot Shots Secret on his 7.3 Excursion and I was curious if anyone had any real life experience with it. He was using Diesel Kleen prior to that.

 

I have been using BG products, hot oil flush before oil change and fuel additive in all my diesels and it has given great results, I don't sell the stuff and I am not on commission I am a fleet manager and I have noticed on units that are idled way too much and no longer regen properly that the fuel treatment has turned that around and got them behaving well again. (no it doesn't fix the mechanical troubles) The dealer rep in my location is awesome, he has very good product knowledge and he's been willing to give test samples for new customers.
