Oil Additive Diesel Engine Treatment: Add to Engine Oil - Makes High Mileage Pickups Like New with Synthetic Material (Treats One Big Diesel Truck) Make Your Truck More Heavy Duty

So I take my 1 star review back. I have since bought more of this product as my skid steer and duramax completley changed how they run, for the better. I now run this in everything I own including my small mowers. I did not notice a difference in my wifes 2016 Subaru though, it never did anything but that is a newer engine. I did notice on the smaller engines I actually had to increase the idle RPM as they idled much smoother and lower after application. Don't be like me, make sure you wait long enough to see/feel/hear results. Also if its a brand new car I wouldn't expect to notice anything but I am sure its helping. Good luck! Old Review: I was hoping to do a good review. I bought some for my Duramax and a piece of equipment I have. I waited 500 miles on my truck, I noticed no difference in engine sound or in mpg, it is exactly the same. My skid steer I could never do a fuel consumption test as I have too many variables. I don't think I noticed a engine noise difference on this either, I recorded the Duramax but not the skid steer, duramax sounds exactly the same. I own a bunch more trucks/equipment and was really hoping to notice something. Maybe I should of tried one of my gas trucks first but I don't see any benefits on my diesel.

I used this in my 2015 Jeep Grand Cherokee EcoDiesel. I have put approximately 3,000 miles on this vehicle since installing the TriboTex diesel formulation. Without question, my engine idles smoother - the previous slight vibration that I could feel in the steering wheel while at idle is gone. The engine is quieter at all speeds. I have also seen that the engine coolant temperature indicator now shows a small but definite decrease in the indicated engine temperature over its historical indication. I am experiencing better fuel mileage, but I can't say with 100% certainty that the increase is due to the TriboTex. I CAN say that my mileage certainly is not worse because of the addition of TriboTex. I am well-enough satisfied with the improvements that I've seen from TriboTex in this vehicle, that I've spent the money to purchase and install it in my other 2 vehicles as well.

Nothing not one change car runs fine before just later sounds . No change no gas mileage increase. I waited til the last day to return it to see any change nothing. I used proline on another car I own , I’m gonna try that next. Not worth the money very expensive

I was very skeptical about this but decided to take the plung and buy it i used it on a very high hour john deere tractor that made a clacking noise when worked hard neither i or the deere tech could figure out what it was i added this and let it run and circulate while fueling and then went to work not sure if there's any more power but the noise never showed up and I think cold starts might be slightly better not 100% on that but it does seem a little easier to start. But definitely quieter no idea on fuel economy because it's a tractor don't exactly have a good way to calculate that but I am impressed that it got rid of that noise and would recommend it probably going to try it on my diesel trucks too.

I have a f350 with 6.7 diesel. I was getting 18 miles to a gallon with the addition of tribotex I now get 21.5 miles

My 2003 Dodge Sprinter was having major issues. Tons of white smoke and rough idle, and had a profession compression test done. It was bad enough that we were planning to put a new motor in it. Decided to roll the dice on this stuff and I'm pleased to report my engine is back to normal. Eliminated all white smoke, smoothed out the idle and I wouldn't hesitate to put in other vehicles. Engine had 220k miles on it, and I'm up to 260k with absolutely zero issues.

Been using it for 5 oil changes now haven’t noticed anything different in the mileage department

actuality the only one on the market that worth consideration. One application and very common eviction in 7.3 power stroke is the thing of the past with new acquired smoothness. Generally this engine is loud and even was discontinued because it is too much so but TriboTEX definitely makes it overall smoother and perceivably quieter. It sure is smaller volume so less worry of diluting your stock oil or dumping volume of things that can disrupt stock oil additives.

Had to wait and see if this works and I gotta say it's expensive but it brought back my duramax power hard to believe something as simple as alittle fluid could change it but this stuff works

This Product is Outstanding it works as described, I have four trucks and all sound much quieter and has more power at take off im very happy with this product cause in the long run it will save from big invoices and possible break downs.

I am a journeyman mechanic, I purchased this to save me the hassle of repair time and cost. I found a better result from a 10 dollar product purchased down the street. I asked for a refund and have had no response
