Is this REV-X additive worth the money? I've heard great things about it but have no personal experience with the product. I like the fact that their winter fuel additive is good to -45F. Snake oil or worth running on a 185,000 mile old PSD?

 

It sounded like snake oil to me.

 

I sell a lot of Rev-X oil additive to 6.0 customers, and run it in my 6.0 myself. It makes a very noticable difference in how it runs in the cold months.
I'm not sure I'd run the Rev-X oil in my 7.3, I don't think it's worth it, but the 6.0 almost requires it.

I have a box of Rev-X fuel treatment sitting here that nobody seems to want.
There are a lot of fuel treatments out there on the market and people seem to have their preferences already.
For fuel, I say anything is better than nothing.
Before you start accusing of being snake oil do some research first.

 

I was talking about the fuel treatment.

I'll look into the oil treatment, I didn't know they made that.

Nothing beats powerservice and 2cycle for 7.3's.

Thats my opinion though.

Some fuel additives reduce lubricity of the fuel and can damage injectors.
Such as Lucas fuel treatment.

 

I'm just trying to find out more about it. Does the oil treatment simply boost the additive package found in the oil? What is the makeup? How much for the fuel treatment nobody seems to want (shipping to 33478)?

Thanks Jim

 

I ran through the MSDS to see what I could find.
Consists of:
Highly refined mineral oil (C15-C50) 35%
Potassium by weight 8.3%
Nitrogen by weight 0.22%
Trade Secret by weight 56.48%

I only have an introductory level of Chemistry from college, but I can try to summarize. Obviously trade secret is stuff they don't disclose due to their formula being proprietary. C-15-C50 is a range for carbon molecules found in the mineral oil. Mineral oil stems from the refinery process of petroleum.

Now if I had to guess what might be in that remaining 56.5%, I'd say they probably have some zinc, phosphorous, calcium, boron, molybendum, to name the bigger ones. Although these would all be PPM, much like a standard oil base additive package.

Anyway I'm not sure what you can decide to make from that, but I figured I would post it up.

 

Thanks for digging in. Interesting stuff

 

As far as the RevX oil additive I tried it and it does help the 6.0. I prefer the Hotshots products personally.

 

Wow, $52.36 for a gallon of their synthetic oil Blue Diamond | Hot Shot's Secret

 

Yeah their motor oil is way expensive.

 

I just read up on all their products, interesting read. The friction reducer looks like an interesting product as well. All it takes is money

 

I will also vouch for Rev-X oil additive. I had some stiction on my 6.0 when it was cold. 4oz of Rev-X made quick work of the problem.

 

For what its worth - i asked my pops about diesel fuel additives in general, as he used to work for Mobil before they were bought by exxon. he was involved with the research into Mobil 1, but more recently in gasoline refining and formulations. his good friend (now kayaking buddy) was their diesel formulation expert who worked there during the switch over to Ultra-Low Surfur Diesel.

As my pops explains it, and as everyone knows, the sulfur that used to be in diesel fuel was a natural lubricity agent. The new ULSD is, by law required to have the same lubricity as the old stuff (called just Low Sulfur Diesel), but how each company goes about their additives is different. all oil companies also add detergents (or injector cleaning agents) to their diesel fuels and the catch is that the detergents exactly counter-act the lubricity agents. so the oil companies (or at least mobil, while he was there) spent tons of money and time to make sure their additive ratios would keep your injectors simultaneously lubricated and clean, without going too far in one direction or the other. so, his advice was to only use an extra additive for a short period of time if absolutely needed. running extra detergent for too long will clean the gunk out of your injectors, but then cause them to run too dry, causing wear. running extra lubricity agents for too long will make things run better at first, perhaps, but then eventually gunk up the works.

in short, his advice was to buy name brand diesel fuel (sunoco, exxon, valero, etc) and not worry about additives.
