Fuel filters

No red hue on mine, but I also haven't ran any dyed fuel

Did any have a RED hue???

Do not remember? I do not use red died off road diesel!!! I do recall them looking really clean. The 2001.5 had a grey tint as I remember. SnoKing

Where did I mention "Red Died Fuel"

All of my filters looked clean too.....and I allow fill ups directly from the pump.

CRAP!!! "DYED" kinda like doing a Break job VS Brake job.

I recall there were some folks who add(ed) transmission fluid to fuel to increase lubricity, on 2nd Gen 24V injection pumps, when ULSD was directed. I never bought into it, I did use Power Service and Lucas though.

I used 2 cycle mix on my 12V. It's designed to burn and lubricate!

2 stroke oil will gum up injectors and cause deposits to form. It’s not designed for Diesel engines. Just because truckers did it in the 70s doesn’t mean it’s a great idea.

I've never been a fan of it in diesels, but its pretty common with the 24V crowd. If you're always pulling hard it will be fine, but at low temp/low load it doesn't burn clean.

I ran it for thousands of miles with the Piers matched set of 215hp injectors that have well over 300k on them now.

That doesn’t mean it’s a good idea. It’s your truck, it’s your money, use and spend it like you want. I’m just saying that’s not what it was intended for. Why not use a proper additive that IS designed to run as a diesel fuel additive?

That just boggles me. People want to cheap out on maintenance stuff on really expensive equipment.

Like I said though, your truck, your money. I wouldn’t recommend it.

I used it for 14 years and 110K plus miles in our 24V without the engine falling out the bottom of the engine compartment.

You lubricate your engine mounts with 2 stroke oil? Well that’s an ingenious move sir. Very slick.

Reading dynamics sir, "in my 24V".

I would love to see some actual documentation that shows ANY manufacturer, supplier, or retailer that shows 2 stroke oil as an approved modern diesel fuel additive for Cummins (24v) engines. Or any modern diesel engines....

Because there isn’t any.....

I did this for a few tankfuls when I was ignorant about fuels and additives years ago when I owned a 12v. I lost an injector pump. I was helped out by Piers Harry himself and educated by more than one injection shop and here on the TDR.

There isn’t a single 2 stroke oil manufacturer that will warranty your engine when the S hits the fan. There are diesel fuel additive manufacturers that claim they will. That would also be a large indicator of what should be used and what shouldn’t.

But again, your truck, your money.....

While not approved, it’s been shown here in lubricity tests multiple times. It’s usually in the top 3 for performance.
Ps. In the 70s it was transmission fluid truckers used as an additive. They believed it was a good detergent for injector deposits. 2 stroke didn’t come along til the common rail era. That was because of lsd. Folks wanted lubricity then , not an injector cleaner.

 

[dieselshadow]

Dumb crap has been used for additives for eons. Does it really matter what it was if it wasn’t designed to do what it was being used for?
Used motor oil has been used. ATF. The list is long and dumb.
NONE of it belongs in any modern Diesel engine. Your fuel system is extremely expensive. They throw away your warranty so easily these days but people are still wanting to throw just about anything in the tank? How does this make any sense?

At one point in time Cummins published an acceptable %age of waste motor oil that could be burned with the fuel. I don’t think they have done that since the CR, maybe since the P7100.
