Same here, I read enough to learn basic guidelines & trust JFPinPA recommendation.

I plan on using Joe Gibbs DT40 when Jake Raby releases the new formula. In September 2012 he stated, "We still have to burn through another 750 gallons of the current DT40 before running the next batch.The new flavor is already developed, but currently a 5 gallon pail of it cost almost 1600 bucks!.

IMHO, Mr. Raby has a passion for his business and has a good handle on what our engines need. Evidently, there was an issue with the first generation oil causing noise on start up.
