Did I see the patents? No, I asked you to show them to me.

I looked up evergreen air and found out that, surprise surprise, the evidence for it being anything sinister exists entirely on people's blogs and consists entirely of the stories of a handful of would be eye witnesses. Now, never mind that these witnesses never have any evidence, never have any images or documents or video. The funny thing is that you're claiming that the government is controlling the internet and censoring all of this and yet a ton of websites about it exist. Are they just censoring all the relevant data right off those sites and leaving the rambling?

So the fuel of larger jetliners has a particulate additive that will damage the engines of jet fighters huh? Well, American commercial jets use a fuel called "Jet A" which can contain a variety of additives

Antioxidants to prevent gumming, usually based on alkylated phenols, e.g., AO-30, AO-31, or AO-37

Antistatic agents, to dissipate static electricity and prevent sparking; Stadis 450, with dinonylnaphthylsulfonic acid (DINNSA) as a component, is an example

Corrosion inhibitors, e.g., DCI-4A used for civilian and military fuels, and DCI-6A used for military fuels

Fuel system icing inhibitor (FSII) agents, e.g., Di-EGME; FSII is often mixed at the point-of-sale so that users with heated fuel lines do not have to pay the extra expense.

Biocides are to remediate microbial (i.e., bacterial and fungal) growth present in aircraft fuel systems. Currently, two biocides are approved for use by most aircraft and turbine engine original equipment manufacturers (OEMs); Kathon FP1.5 Microbiocide and Biobor JF.[15]

Metal deactivator can be added to remediate the deleterious effects of trace metals on the thermal stability of the fuel. The one allowable additive is N,N’-disalicylidene 1,2-propanediamine.

Military jets on the other hand use "JP-8." which uses different additives and is designed for more high performance engines.

Now, is it possible that the two different planes use two different kinds of fuel because, as your friend said, their engines are different and the fuel of the jetliner could cause damage in the higher performance jet fighter with its more fine tuned engine? Such as when you put normal unleaded into a high performance race engine? Maybe some of the additives used in the commercial fuel don't work well with the different engine design used by the military? Occam's Razor: Either different engines use different fuels because different fuels are better suited to their needs and design OR they use different fuels because the government is secretly injecting dangerous additives into the fuel of airliners for the purposes of some kind of unspecified nefarious plot and they somehow have hundreds of thousands of airline workers in on this scheme.

Ah. So to summarize
"You're a liar"
"No I'm not!"
"Prove it."
"No."

Oh and thanks for the personal insult up above. Real neat. High quality argumentation.
