Hot Shot's Secret DDD Diesel Oil and Fuel Additive - 128 fl. oz.

I had a Ford 7.3 turbo diesel that blew - blue smoke every cold start, had some loss of power and was running overall a bit rough. Bought this on the suggestion of a older diesel mechanic friend to try before replacing, plugs, injectors etc... Did a oil change and put Rotella in it with almost half the bottle of the oil additive (per bottle directions) along with a brand new tank of fuel and fuel additive. Within 4-5 days of driving I could tell a big difference in power and it blew - blue smoke a lot less and overall the engine was alot happier. I owned the truck for about a year before using the additive. I had done multiple other oil changes on it without this effect.Only downside is that with my truck at least Id only get about two oil changes worth (green bottle) the fuel additive (orange) will last forever based on the instructions for how much you put in a tank and when.Its a good product, but id buy another green one along with if your just getting started with this stuff, you gotta double the amount you put in the first time you run it through so it goes quick (oil additive)

My dad has a '96 F350 and I have a '99 F350 4x4, both with the bulletproof 7.3L diesel. I work overseas so my truck doesn't get used very often. I get home and drive it and it began to not start well, run well, felt very sluggish, and just all around not the typical 7.3. I hooked it up to a computer and codes popped up saying I had a bad injector. A buddy of mine told me to not change my injectors and to try Hot Shot Secret so I decided to give it a try. I changed the oil and put the recommended amount of oil additive and diesel additive in and Goodnight Nurse!!! I drove the truck about 500 miles and it hasn't driven so good in years. I just recently used the same stuff in my dads truck (It was my truck for 10 years until I sold it to him) and wowza, unbelievable difference. It felt like my old truck again. Fast starting and immediate throttle response. My dad was even immediately impressed with it. I'll never use anything else and I will recommend this stuff to everybody. Best stuff on the market and I thank my buddy all the time for recommending it to me.

Used stiction eliminator in petrol Toyota 2az-fe. Added far less than 4oz per quart(400ml instead of 500ml).The engine lost power yesterday after 300km/1 week with the additive in the oil. Bearing knock under load. Barely managed to get the car back home! Who is going to pay now the rebuilding of that engine?

I can't provide enough good comments on ALL Hot Shots Secret products. I use them in my Diesel, Gas, Trucks, Cars, Motorcycles, and mowers. In all vehicles I noticed and recorded an increase in fuel mileage. Vehicles run smoother and shift smoother. My cabinet and work bin in the truck always have a supply of Hot Shots products. Buy and enjoy. Well worth the price.

This stuff is no joke. Bought my 97 7.3 powerstroke used. First thing I did was change out oil with rotella and a full jug of the stiction Eliminator and topped up my fuel with the diesel additive. Changed out again after 3000km...the crud that came out of the engine was incredible. Put Amsoil in for the second change. Engine runs buttery smooth, also had my oil tested 4000km in, no fuel in my diesel, hardly any detectable wear metals. If you want your diesel to go the distance do yourself a favour and buy this combo! Best thing to do is use this before you need it. I’ve seen YouTube videos of guy saying it doesn’t work. It takes time, you can’t just dump it in and work immediately. Takes a couple thousand miles of good hard driving for the stiction eliminator to dissolve the coking back into a liquid.
