I recall a thread awhile back regarding Stanadyne & LMM/ULSD. I just picked up my supply for the year and noticed something interesting. The single use bottles say formulated for ULSD/07+ diesels. But the larger jugs don't have this label. Started looking closer and the box the jugs came in say production date AUG 2005?? Makes me think I should return it and get something a little fresher, let alone with the USLD label wouldn't you think?

Interesting to hear what others have to say about this but according to the dealer the formula has not changed for years & the ULSD label was only added to appease industry/gov't. This could be as factual as whether or not this stuff even works in the first place ;) but I'll continue to use it. Cheers!
