I understand it's a wear test, but isn't a big reason we do it is for our ve pumps? Our fuel delivery system is a lot different than a common rail, and wasn't designed with ULSD in mind. I've heard that the added lubricity also helps keep o-rings and seals in the pump from leaking. Correct me if I'm wrong.

 

It stopped the leak on the IP on my 93. That said, i'm worried about the injector deposits he was talking about. I'm on my 3rd set of injectors in my JD 6410 and its got me wondering.

 

Agree, I've been running a quart of ATF with every tank of fuel since ULSD came out; for that very reason.

In a previous job I dealt with a customer that was having pump after pump fail in his older thermo king units; due to ULSD; they started running a mix of ATF in the diesel fuel until the units could be replaced/updated; problem solved; never had another failure. He was the reason I began running ATF in my truck.

 

highlighted in red are even more reason to run a lubricity additive, ESPECIALLY in our system.

i'm saying this

1. lubricity additive is beneficial to our fueling system
2. 2 stroke oil is not the best lubricity additive available.
3. Optilube XPD ~$3 per tank
4. 2 stroke oil ~$1.70 per tank

 

and if you're paying more than $3 for that quart of ATF, you're robbing yourself of a good fuel additive. try the Optilube XPD

 

Its around a $2.00 a quart thru work; bulk.... No biggie, more or less an extra gallon of fuel.

 

Where are you guys getting the Optilube? I'm only seeing it online. I'm willing to try it instead of the 2 stroke. The zinc fouling the injectors is what concerns me about the 2 stroke.

 

I've simply read too many charts and stats showing that 2-stoke in diesel is a viable fuel lubricant to completely disavow its effectiveness this late in the game. This is NOT a newly discussed topic.....

But just to be clear, I'm not claiming 2-stroke to be the "best" lubricating product out there either but that its worlds cheaper than some of the stuff available, and merely that its better than running straight ULSD in a pre-2007 truck.

I know there's plenty who prefer other products, but for the prices of what some of these fuel lubricants cost it would be cheaper to simply use ULSD and replace parts as needed rather than spend thousands and thousands using some high dollar fuel additive.

As for injectors, well I changed mine out last year for some RV275's. I've been using 2-stroke for years and the ones I pulled out looked and ran fine.

 

Amsoil and SoyShield cost me about $3 and $2.50 respectively per 30 gallon fill of #2.
