Check engine light. Followed the instructions, added one oz. to a 26 gallon tank. Half way thru the tank got a check engine light and an obd code. Not sure if related to EDT or not but the problems started after adding EDT.

Hot shot secret is the best Hot shot secret is the best. It basically pays for itself because of the small increase in mpg. At the same time it cleans and protects the fuel system. No brainer for longevity of expensive fuel system parts.

So far I have purchased and used stiction eliminator and Diesel extreme and gasoline extreme! So far I have purchased and used, friction eliminator in three of our four vehicles. We'll have to wait for oil change on the other vehicle. But my little get around car was having lifter and timing chain tensioner problems, and the stiction eliminator has so far completely cured that, this happened only when I started it up! so I guess it has cleaned out some oil passages and slicked things up!!! I'm very happy as this car has 330,000 miles on it!! Hoping using these products will get a little more miles! I also bought Diesel extreme for my truck and gas extreme for the cars! Noticed a giant difference I love these products and I'm going to keep buying from Hot shots!!! My wife took her good car to work after using the gas extreme and when she came home she wanted me to ride with her and check out how much more power it had! Very noticeable especially if your wife notices it! LOL I'm looking forward to buying my oils from them! Thanks

From their blue diamond 5w40 to the fuel additives I demand the best and that's what hotshot secret is, the best!!
