Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.066". With Steam Holes. Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

Great diesel treatment for everyday use
Size: 128 fl. oz, 1 Pack
I use this Hot Shot’s Secret Everyday Diesel Treatment for my diesel truck, and it has been a great product to keep on hand. The 1-gallon size is a good value because it treats a lot of fuel and makes it easy to use regularly. I like that it is made for everyday diesel maintenance, not just occasional use, and it gives me extra confidence that I am taking better care of the fuel system. A very practical product for diesel owners who want something reliable for regular use.

Noticeable MPG boost for my F-250!
Size: 128 fl. oz, 1 Pack, Size: 128 fl. oz, 1 Pack
I’ve been using this Everyday Diesel Treatment in my F-250 for a while now, and the results are legit. The most impressive part is the improved fuel economy—I’m definitely getting more miles per gallon than before. ​The engine also sounds smoother and seems to have better throttle response. I love that this one-gallon jug treats so much fuel, making it a great value for the price. If you want to keep your fuel system clean and save some money at the pump, this is a must-have. Will definitely keep buying!

If you own a diesel engine, use this.
Size: 128 fl. oz, 1 Pack
For diesel owners looking to protect their fuel system, Hot Shot's Secret Everyday Diesel Treatment (EDT) is a heavy hitter in the world of additives. This 1-gallon jug is designed for the long haul, treating up to 1,280 gallons of fuel, which makes it incredibly cost-effective for daily drivers and fleet owners alike. The primary draw here is the 7-point cetane boost, which noticeably smooths out rough idles and improves cold starts. Beyond performance, it serves as a critical insurance policy against modern "dry" Ultra-Low Sulfur Diesel (ULSD) by adding essential lubricity to the fuel pump and injectors. It also features a demulsifier to help separate water from the fuel, preventing corrosion before it starts. While the 1-gallon bottle is bulky and requires a smaller dispenser for easy pouring at the pump, the peace of mind and improved MPG make it a staple for maintaining a healthy engine.
