What is everyone using for friction modifier in their diesel fuel. I have been running Stanadyne Performance but what to explore other options. 2013 f350 all stock.

 

Welcome to FTE. Asking what additive to use is like asking what oil to use. Many different opinions here. I use K100. I have been using it since the truck was new. I'll assume that you mean lubricity supplement for the ULSD, correct?

 

Yes lubricity additive

 

K100 is an all in one product. It's run at 1000:1 summer and 500:1 in winter. I've currently got about 65k miles on my truck.

 

optilube summer and optilube XLare my additives of choice for cetane and lubricity in the summer time. Recommended by others on this forum.

 

Hot Shots EDT in the warm weather, will switch to the Anti-Gel version for the cold months.

 

Since this has been nothing but different options so far I'll add another. I use motorcraft PM22 in summer and PM23 in winter. Used it since new.

 

rarely use anything. If really cold I will be break out the M/C PM 23

 

I've been using the Opti-Lube products since 2007.
I'm not really committed to every tank., But throw it in when I remember

 

Heard good things about Hot Shot Secret's EDT and Opti Lube. I personally just started running a homemade mix of Howe's Diesel Treat and Stanadyne Performance.

 

There was a video posted on here i think. It was showing the lubricity of fuel additives and Stanadyne and Hot Shot came out on top. They didn't test the M/C m22.

Thats the study that steered me into OptiLube products. OptiLube XL wasn't a product at the time, but OptiLube claims it performs better on lubricity than XDP which did really well in the above study.

But that study also points out some other good options, like Schaeffers, Stanadyne Lubricity, and Power Service.

 

I run the Stanadyne Blue year round forumla and every other tank the Stanadyne lubricity. Does it help? Can't say, but sure doesn't hurt. I have been using it since day one of my truck.

Stanadyne also is one of the few additives that states they are a de-emulisifier. That means they do not try to force the water through the filers so the engine can burn it but makes the droplets clink together so they are larger and can be filtered out of the fuel.

Here are a couple emails i received from PowerService about their DieselKleen

Dear Larry,

Thank you for taking the time to contact Power Service. Our products are neither an emulsifier or demulsifier. They make water soluble in diesel fuel, or in other words it dissolves water and makes it part of the diesel fuel. The only additive that contains any alcohol is Diesel 911, and it contains a very safe, high molecular weight alcohol that will not cause any engine harm. If you have any further questions please give me a call at 817-599-9486 and ask for Jessica.

Thank you and have a great day,

Jessica Crabtree

Hello Larry,

Thank you for taking the time to contact Power Service Products. Diesel Kleen does not have capabilities to reduce the amount of water in the fuel system, it is designed as a performance additive to increase cetane for better fuel economy, improve the lubricity of the fuel to protect the high pressure components of the fuel system, and clean and prevent IDID's (internal diesel injector deposits) from building up on injector tips which could cause them to stick. Our product Clear Diesel disperses contaminates and removes water in diesel fuel as well as stabilizing fuel and preventing thermal and oxidation degradation of fuel stored up to a year. Clear Diesel is no an emulsifier or a de-emulsifier, it is designed to solubilize the water in the fuel and break it down into part of microns so small that they will not harm you engine or fuel system. Attached to this email are the tech bulletins for both products as well as our year round recommended treatment schedule for all of our products. If you have any other questions please feel free to contact me at the number listed below and I will be happy to discuss them with you. Thank you for being a Power Service customer!

Respectfully,

I started using Opti-Lube XL in February after doing a bit of research like you appear to be doing. My focus was the lubricity, which is why I got the XL. I just ordered some XPD for this winter, and the reason for XPD over the Winter product is again the higher lubricity while having Anti-Gel down to -10*. See attached Opti-Lube product comparison chart.

 

I'll wait for the naysayers to chime in about the additives like mine that breaks water down to the molecular level and encapsulates with a burnable compound which means it will burn in the combustion chamber and prevent rust and corrosion in the fuel system. No problems in 65k miles of driving. I've also had contact with a company representative for K100 also. They are only about 55 miles from my house. Been running it since new and I trust it.

K100 is product that does it all or so it says. It's an anti-gel, fuel stabilizer, eliminates water, cetane improver 1.5 to 2 points, adds lubricity, fuel system cleaner, dissolves alphaltenes and puts them back into the fuel, combustion improver and reduces paraffin formation in cold weather. Here's another link to the alphaltene problem with modern diesels and wouldn't you know it, it's another fuel additive.
