If I buy this fuel additive in bulk, what is the shelf life of this product?

5+ years (just give it a good shake or two!)

I just got my first diesel (ecodiesel dodge) and looking for input on this. Is it worth trying and does it really help with mpg?

I have been using it in my 2016 Ecodiesel since I purchased the truck in May. It seems to help my overall mileage about 1-2 mpg. I drove from Oklahoma to Seattle. 4600 miles. Averaged 25.6 overall. I felt this was very good for a 4 x 4. I'm very satisfied with the product.

How much of this per fill up, assuming about 30 gallons of fuel?

Only 2-3 ounces per tank, thanks!

Do you sell this product in 5 gallon buckets? Am interested.

Yes absolutely! Please see this listing: https://www.amazon.com/dp/B09JWZBX1C?ref=myi_title_dp

Long time proven results

I have been using Hot Shot's Secret in every tank of fuel I've run, in every diesel I've owned. I have over 3 million cumulative miles of running EDT. Using my stock 2021 Ram 3500 HO with 35k miles, I tested it against untreated fuel and Archoil AR6500. EDT managed a 1.5mpg increase over untreated fuel, and Archoil lost 1mpg. Time between regens has consistently been at 24hrs with EDT, which is when my truck will actively regen regardless of soot load. Untreated fuel dropped to 11-12hrs between regens, and Archoil dropped to 4-6hrs. Firepunk also recently dyno tested EDT, and saw a ~20hp improvement, which indicates that it does actually improve combustion. EDT costs about ¢6/gal to run, and more than pays for itself in fuel economy improvement. The added lubricity, better burn, and lower gel point are just added bonuses. This is the best performing additive on the market, out of the few that aren't snake oil
