Ty We have (had) 5 7.3 on the place at one time. Now we are down to 4 7.3L and one 6.0. Not a one of them responded the same save two of them. Not a one got the same MPG, Now at least two of them got the same MPG rang towing. Empty they were close but the single cab was a little better. On had 3.55 ZF6 300/200 injectors. and the other had 4.10 and the E4OD stock injectors.
But as far as fuel conditioner my pickup (the one in my sig)when it was all stock save a intake exhaust and tune ZF5 and 4.10 gears would do around 14.7 to 15.3 driving 70@2500 rpms. BUT if i ran powerservice in the gray bottle It would jump up to 17.2 to 17.8 With the same fuel driving the same roads. Now if I went on a trip it would depending on the fuel get 18.3 BUT most times was 17.5 to 17.8 MPG I did get right on 20 for one tank BUT i was driving about 55 mph. The other ones would not do as good other then the single cab. If i did not run powerservice diesel clean it would slowly drop off as i ran more fuel through it and after about 3 tanks it would be back down to the 15 range. Some additives would get me under 15 ALL the time.
I feel from what i have done and tested not all 7.3 respond the same. And they do not all see a benefit with fuel additives. And some get worse with fuel additives. Not sure what but that is what I have seen. I am in no way saying what you have seen is wrong. Just saying what I have seen and tested. But in all honesty A fuel additive WILL not help if you have GOOD fuel already. OR if your injection system is dirty then running a good cleaner through every 5000 miles will help. Or less depending on the fuel. And if the fuel is not good A cetane improvement will help. There are cases where the additive and cleaner will not do any good. Most fuels now days have a cleaner in already. So adding it could in fact HURT the injection system. And cause faster destruction. Some additives ARE not meant to be mixed and can cause greater problems then if you would have left it alone. That is why I say a good cleaner every 500 miles then if much in between just a good Cetane booster. I would also (like you did TY) go talk to the fuel station you use and see what is in the fuel BEFORE adding to mush stuff and ask them what they are using. You could blow your money for nothing. and hurt the injection system. With these new CR engines that could be a viable concern or SHOULD be.
Like stated before I will be testing things to see what i think and how they work for me. The testing will be real world testing for the Cetane and cleaners PLUS bench testing the cleaners. Bench testing cleaners can be way off to.. Some of the cleaners do not take as much per gallon then the other ones. So one is more concentrated then the other. So the more concentrated ones will have the advantage so the will got "thined" out to be the same concentration as the others to be a more honest and true test.
Like I said TY not calling you out. Just stating what I have seen. What you have seen is true for you. From what you have said you have higher quality fuel then we have. I wish we had better fuel up here! We should after all this is where they get the oil! LOL
