A method to make your diesel engine running better especialy after serious mileage

[Duffman]

I've been running it every second tank in my 6.0 powerstroke for a few years. Because I alternate it with anouther additive I cant really comment on any fuel efficiency gains but I feel the lubricity benefits are worth it, especially in winter.

I may have to try that 2 stroker stuff in my old diesel in place of diesel service or the like.

MMO does have some sharp light materials in it, but on motors that tended to miss and stumble it would quite them down, I have observed it increase compression ratio also. I have experienced fuel consumption decreases with MMO as well but that may have been because the motor had problems and it was covering it up.

I've tried it mine. Instant reduction of FE. As the motor has already seen 185k miles of use I didn't figure it would hurt, and maybe would help a tiny bit. Nope. This HPCR (high-pressure, common-rail) motor didn't like it for "help". A PM from another contributor here indicated that it may be of help on older, low-pressure motors where the fuel pump is of a different design and used fuel as a lubricant.

I'll stick with ordinary fuel additives from hereon . . where Standyne Lubricity Formula is the choice of injection specialty shops (serving industry).

This product should be the basis of comparison, IMO.

There are plenty of websites that discuss the TC-W3 in diesel, and what TC-W3 to diesel fuel ratio is recommended.

I DO NOT WANT TO START A UNICORN thread, but some also attest to adding one ounce of TC-W3 per five gallons of gasoline (a ratio of 1 to 640). There are many reasons why this is recommended and many of the potential concerns (plugged cats, etc.) do not appear to apply. I have tried it (A-B-A-B) and have my own results; however, I don't want to be bashed or have my testing practices questioned -- since that normally results (on various websites) whenever these types of fuel additives are discussed.

I know its a typo, but I want some of that 'assless' oil......lmao no pun intended. :-D

Oops. What a crack up (pun intended).

rmay635703-- what do you mean when you say MMO" has some sharp light materials in it" Please explain I assume you mean organics ,I wont run it if it has say metal

ahh...... that's what I was looking for, a possible mechanism by which the engine ran better with some sort of top-end lube mixed with the fuel.

It's likely freeing up gunked up rings and ring lands for a better cylinder seal. That would make sense.

I wish I had heard about this factor earlier. My injection pump failed, cost me two Grover Clevelands to have it replaced.

[AndrzejM]

My engine's injection is based on the Bosch pump pretty much the same like in VW's TDi engines. And that works for me like a charm So I'll stay with 2 stroker's oil.

I would rather use power service and up the strength, or run diesel purge directly to the enjectors to clean them.

Bio-D is great and should not kill the pump if the tank is very dirty it could loosen gunk and clog the pump killing it assuming the pump is be for the fuel filter. If after the filter gust get a few cheap ones or an inline and change them a few times. Also from what I remenber Bio-d will wet dried orings/seals and switching back to ULSD can reshrink them causing leaks.
