Lucas Additive

[gottabadf250]

My buddy with a 6.4 used this in his truck and had great success with it.

I'm gonna try it out in my 6.0 and I'll let you guys know if I see any changes.

Anyone else tried it?

if its the fuel additive...have at it, but if its the oil additive, i would STRONGLY recommend you NOT to do it, it thinkens the oil, which is a bad idea for the 6.0 with heui injectors, it would be ok for the 6.4 because they are common rail and the fuel system is not dependent on the consistancy of the oil for proper operation. maybe you already knew this i dont know but its your truck and you can decide what you want to do im just giving my own personal insight. hope this helps man.


ETA: i forgot to mention, lucas does make a synthetic version of there oil additive which they claim is safe to use in powerstrokes (7.3 and 6.0) but they themselves dont recommend using the original oil additive in them. either way i wouldnt use either of them.

absolutely agree with hazard. I actually got into a discussion with a buddy over this recently (he never shuts up about lucas) and, after some research, even he conceeded that it shouldn't be used as an oil additive in a 6.0.

The big fella on powerstrokehelp.com has a video on his site where he talks about as well.

fuel additive is GREAT!!!! I love it. But dont do it for the eng. Diesel oil es very crutial and should not be messed with.

What do you mean had "great success" with it? A 6.4 is still a new motor and even if you put the wrong oil in it you wouldnt know the damage for quite a while....

I'm not going to put any lucas in my 6.0, but my Father who is a truck driver swears by it as do alot of his fellow drivers...so no idea really!

Lucas oil has very little lubrication properties which is the main reason you want to use an additive. Staydyne makes a great additive that lubricates well as well as using 2stroke oil. I personally wouldn't use any lucas product in my vehicle. I have seen several tests and studies that show the lucas oil causing the oil to foam. Of course the autozone demo they have isn't capible of 1000+ rpms so you would likely never see it happen

It's the fuel additive that I'm talking about.

He said in his 6.4 he saw more power and very noticable increase in fuel economy.

Thanks for the info on the oil additive!

granted its a 7.3 but I put it in my truck and I experience less oil usage over a 5k period
