Well I've waited for months for some kind of feed back about OPTI-LUBE Oil Fortifier and it seems no one has tried it so I was tired of waiting so I tried it myself.
Location: Oak Point Texas...
2010 F350 Dually 6.4L
28K miles (light towing) - Polo horses
Mainly light mods with running custom Tow tune with EGR off and DPF still on. (Yes DPF coming off during Thanksgivings)
Used as always Motorcraft 15w-40 and of course their oil filter as well.
Engine did knock in the engine area which is the rockers on the driver side. The knock occurs at start up and goes away when the engine warms up or on a very hot day towing heavy the knocking can be heard inside the cab with the radio off (hard to hear it so you have to focus for hear it)
I have bumper to bumper 100K mile warranty and have all maintenance pre-paid and done by Ford dealership.
I sent off for a blackstone report before changing the oil and will do the same after this change so we will see if there's a difference. I will post it to this thread.
I purchased a gallon of the fortifier and on the first change you suppose to use 24 oz and then 16oz for all the rest of the oil changes for our awesome trucks.. The appearance of the product seems more transparent than Motorcraft 15w-40 and pouring the product into the funnel was a lot faster so the product must have a thinner in viscosity. Of course I just using my eye no measuring instruments.
**Only added to motor oil**
At startup no more knock, heavy tow no more knock. The engine does seems to run quieter and does sound better aka less diesel noise.
I really can't tell, but of course I'm no pro, I can tell the speed difference between Polo ponies but not my truck. Mods I can tell a difference but I guess this didn't make that big of a difference. Maybe if I drove it more.
Gas Milesage -
Before I drove 200 miles (My normal route for Polo games) and the next week the same time and distance. Before my gas mileage was about 12.5 now it's 13.3 so there's an improvement and probably better but I can't say I drove the same.
Their comments about the product with mine added:
No true way to measure
Lower Operating Temperatures
Well coolant temp are the same but I do have to say oil temp do seem to stay cooler longer.
Improved Fuel Economy - Up To 15%
Well not for 6.4l but there does seem there some improvement.
Reduced Power Draw - Up To 12%
Well I can't tell that much but maybe 1% to 2% but I didn't use a dyno
Less Rust & Corrosion
Will never know unless the engine blows up.
Less Sludge & Varnish
No way to compare this unless you have two trucks to compare with lots of miles.
Less Oxidation For Extended Drain Intervals
This just makes my head hurt... I have the oil changed ever 5K miles no matter what even after I do DPF delete, going to Mobile 1 and adding BulletProofDiesel oil cooler and external oil filters. (Wasting money? You bet, much rather waste money on oil than replacing the engine down the road)
Added Protection Against Water Contamination
Okay no idea how it does that, I change my fuel filters every 10K and drain the water out of the fuel every month.
Adding the product to my other Fords and vehicles on their next oil changes as well.
2010 Ford Focus
2010 Lincoln MKT
So as you can see I'm taking some serious risk with my vehicles but I do believe it did make a difference.

Friends are nothing but leeches (Joke, if you knew me well you would get this)
Would I buy it again:
I'm about to switch to their XPD Diesel Fuel Improver in about 3 months as well for my 6.4l
If there's any other product you guys thought about using and if I haven't used it and think it would help I will gladly give it a try and do a write up.
I hope you found this information helpful.
