How many 6.7L CTD owners use some kind of lubricity/cetane improver?
Sulfur is not a lubricant in of itself, but it can combine with the nickel content in many metal alloys to form a low melting point eutectic alloy that can increase lubricity. The process used to reduce the sulfur also reduces the fuel's lubricating properties. Lubricity is a measure of the fuel's ability to lubricate and protect the various parts of the engine's fuel injection system from wear. The processing required to reduce sulfur to 15 ppm also removes naturally-occurring lubricity agents in diesel fuel. To manage this change ASTM International (formerly the American Society for Testing and Materials) adopted the lubricity specification defined in ASTM D975 for all diesel fuels and this standard went into effect January 1, 2005. The D975 standard defines two USLD standards, Grade No. 2-D S15 (regular ULSD) and Grade No. 1-D S15 (a higher volatility fuel with a lower gelling temperature than regular ULSD).
I don't quite understand your point.I know why this poll was started and I'm pretty sure Sharpy didn't want it to turn into another debate.
This is the polls section, let's keep it to answering the poll and augmenting your vote with why you do or don't use additives, we can argue the merits of both someplace else.
I understand your reasoning and I'm on your side when it comes to the use of additives when it comes to ULSD, all I'm saying is let's keep this simple. Yes or no and what purpose it serves for you, no need for giving specific facts, reports, etc as to why as I know how threads devolve into endless debates. This poll isn't about who is right or wrong, just who is doing it and why, even if it's just opinion or "what they've done forever." :thumbsup:I don't quite understand your point.
Someone posted that they didn't use additives and augmented it with the fact that neither the vehicle manufacturer nor the engine manufacturer stated in their manuals that additives were required. I happen to agree and said so.
My second post was meant to augment why I thought additives weren't required.
No one is arguing or debating. Just presenting facts to agument reasons.
OK gotcha. Thanks.:thumbsup:I understand your reasoning and I'm on your side when it comes to the use of additives when it comes to ULSD, all I'm saying is let's keep this simple.

Think about it, any manufacturing company, not just automotive relies on aftermarket parts sales. Their not going to recommend something that going to add life. all they care is if it makes it past their warranty period..Cummins has no say in the 6.7L. any CTD once it's in dodges hands...If it was needed I am sure Cummins or Chrysler would have it in the manual.
I tried to edit the poll for more options like you suggested, but either my brain stopped working:bangheadr it wont allow it...:confused013:NIGHTSHIFT SUCKS:homer:If you voted yes, please post up a quick message as to how often and why. Lubricity, cetane/power improvement, injector cleaning, anti-gel...? Every tank, every oil change, random...?
I voted yes because I run a bottle of Diesel Kleen every oil change to try and keep the injectors cleaner. I don't do it every tank for lubricity or cetane boost.
