Order the Hot Shot's Secret P040416Z Diesel Extreme Fuel Additive from GAP for your vehicle today. Diesel Extreme is a fully formulated, concentrated cleaner that removes all internal diesel injector deposits (IDIDs) including waxy and polymeric deposits. In addition, Diesel Extreme contains a top tier level of cetane booster, lubricity additive, and fuel stabilizer to provide maximum performance while cleaning the fuel system. Hot Shot's Secret Diesel Extreme is a premium 6-in-1 diesel additive, containing the most concentrated detergent formula on the market. Diesel Extreme fuel additive is formulated to resolve issues related to Ultra-Low Sulfur Diesel and greatly improve your truck's performance and fuel economy.
Engineered with specific detergents, Diesel Extreme will safely remove and prevent Internal Diesel Injector Deposits (IDIDs), External Diesel Injector Deposits (EDIDs) and other forms of varnish and deposits that cause scarring and wear, which leads to premature failure of fuel system components, including fuel pumps and injectors. Diesel Extreme fuel additive also includes a powerful cetane improver, improving your diesel fuel's cetane rating by up to seven points, to improve combustibility, horsepower, and fuel economy. By improving combustibility, this diesel fuel treatment reduces the number of diesel particulate filter (DPF) regeneration cycles that are needed. Diesel Extreme also contains a lubricity enhancer to further reduce wear, a water dispersant, rust and corrosion inhibitors and a fuel stabilizer. Diesel Extreme fuel additive will improve your diesel's fuel economy, increase horsepower, clean injectors, improve cold starts, eliminate excessive black smoke, and improve reliability. This diesel cleaner additive is recommended for use in all diesel engines.
Hot Shot's Secret Diesel Extreme is formulated with specific detergents to safely remove and prevent Internal Diesel Injector Deposits (IDIDs), External Diesel Injector Deposits (EDID's) and other forms of varnish and deposits. Not all diesel additives on the market will remove IDIDs, as a special detergent is needed.
In order to effectively improve your diesel's fuel economy, horsepower and combustibility, your fuel system needs to be clean of deposits and run fuel with a high cetane rating. Diesel Extreme not only cleans exceptionally well, it also provides a powerful cetane boost of up to 7 points. This allows for the fuel to burn more efficiently, increasing performance while also reducing diesel particulate filter (DPF) regenerations. The lubricity additive in Diesel Extreme also increases your fuel's lubricity, improving protection and reducing wear. This helps combat the ill-effects of Ultra-Low Sulfur Diesel. Diesel Extreme is a fully-formulated 6-in-1 diesel additive that addresses both common and uncommon problems with diesel fuel, making sure your diesel is always running at peak performance.
1 quart treats 80 gallons of diesel fuel.
16 oz. bottle treats 40 gallons of diesel fuel.
Recommended Frequency:
Use one treatment of Diesel Extreme every 6000 miles.
Uses:
Diesel Extreme is extremely effective in middle distillate fuels to improve combustion and ignition efficiency, enhance fuel economy and maintain fuel in a clean, stabilized condition. Hot Shot's Secret Diesel Extreme is safe in all diesel engines: semi-trucks, pick-up trucks, farm equipment and autos.

Not all the same! Some Great, some not.
I bought the queen 2 pillow green blue pillows first. Absolutely love them. Later I saw they had them with cooling on both sides and bought the queen 2 pillow set of that..not the one that said firm. These new ones are way over stuffed and very firm, they do not sink in softly like the first ones. So I would only get the green/blue tag ones they are 5 star-best i have used, this last one 3 star and regretting them. I took enough stuffing out of the two new ones to make 1.5 new pillows, now descent but not the soft comfort as the first, I thought that was what I was paying for. So it's a gamble. The lighter color stuffing is soft and has more of a memory foam reaction, the other darker one feels like stiffer foam with more air in it. It's still soft but doesn't feel like memory foam.

Starts off very cool
I got this pillowcase for my husband because he is always hot at night and has trouble falling asleep because of it. The fabric of this pillowcase feels very similar to a cooling pillowcase that I have had for years and love (but is discontinued, so I can't get any more of them). It is a silky smooth, not-quite-satin fabric that feels initially very cool to the touch. It fits on a standard size pillowcase, and has a slight pocket end (not very much overlap, so it does come untucked during the night).
My husband reports that this pillowcase is very cooling right when he goes to bed, but after a short while, it warms up and isn't really cool anymore. So if he doesn't fall asleep right away (and he usually doesn't), he has to flip it over. His head puts out a lot of heat at night though, so the pillowcase might stay cooler longer for others.

Doesn’t stay on the pillow.
Color: Gray, Size: Queen (2 Count)
The concept is there, but the pillow case doesn’t stay on. Every night the pillow case slides either half way or completely off the pillow.
If it stayed on I would love it
