Fuel Additive Comparison

[ColoradoDoug]

I've seen the results that show bio, then Opti-lube, then fttp (?), etc. I have not seen Motorcraft or the XDP additives in any of the comparisons. I know a number of people seem to like both, but have there been any tests including these two for lubricity and cetane boost? I just finished the last of my Stanadyne and am ready to try something else.

Try Rev-X i swear by it and so do allot of people do. It cleans injectors and seam to give the best increase IMO on cetane. I have used RBP's as well and liked it.

ive only ever run Opti-lube XPD, its not about seat of the pants feel for me, I don't really buy that... just test results. A quick google search netted a few of the major studies out there:

I run rev-x and diesel kleen + cetane boost in the silver bottle and truck seems to thank me for it. I think the DK got pretty good reviews in the lubricity study that is floating around here somewhere...

the "lubricity study floating around here somewhere" is in the post above yours.

These are the results I mentioned in my opening post. That's why I'm asking if there are any test results for XDP and Motorcraft additives since they were not part of the test.

the only fuel additives i'd run are Rev X Distance or Opti lube XPD.. oil additive Rev X only

???? The motocraft additive is Stanadyne, it came in #8 in the lubricity study.

Every time one of these fuel additive comparision threads pop up I feel compelled to respond, so here goes.

When looking at a fuel additive one must look at the whole package, not just lubricity. For instance a bio blend is probably the best lubricity improver out there, but what does it do for cetane? Bio actually has less power per gallon than reg diesel. Bio actually has more of a problem drawing moisture than reg diesel, so you would have to add a demulsifier. It also does nothing to stabilize fuel.

I am not calling out bio blends, just using it for argument sake since that lubricity study has been mentioned already, but the same can be said for 2 stroke oil also.

When selecting a diesel fuel additive everything I have mentioned above must be taken into consideration. Do you really "need" the best lubricity improver?, or would a correct balance of lubricity,cetane improver, water demulsifier, and fuel stabilizer suit your fuel system better in the long run?
