Supposedly reduces emissions but there’s some conflicting data on just how much if any it actually does. What it does do is reduce MPG
How does it reduce MPG? It is only put into the exhaust.

It’s the lean burn design that reduces the mpg, not the DEF.
 
It is official, when I say Fargo suks and the dining is severely limited I am serious. The health dept just found caged pigeons in the basement of our local Chinese Buffett. Personally as a Marine I have ate much worse, but at least I knew what I was eating! Arghh.
 
I still think the def masks the emissions,still there just a different flavour to suit the emission police..
 
It reduces the nitrogen oxides produced in the lean burn diesel exhaust by being selectively injected into the cats. Without it, the cats alone couldn’t handle the NOx load.

Can you pee in it in a pinch? Just looked at the ingredients.
Hey Hoppy, I tried every combination today on the vacuum advance. I need to buy a vacuum pump or just suck on the hose and put my tongue over the end to test the diaphragm. (damn, that sounds gross doesn't it) Nothing I did makes any difference. It still pings the same. I just plugged the vac line with the same results. If I remember, when I installed the Pertronix, I took out the heavy long slot spring and put in the Mr Gasket spring Way too light for a auto car I bet.:BangHead::BangHead::BangHead: Today, I backed the initial off from 15° before to 10° before but I still had the same amount of ping. Total was at about 35° at 2500 rpm.

Think you answered the question. Those springs hit fast. The long slot one slows it down on the high end. You can get away with changing the other to the Mr.G. You would be surprised how many I get in with two of them. Have a bunch of them for Carlisle new and used.

That stock light spring and the Mr Gasket spring works good in my 273. It's a 4 speed but I don't rev it and side step the clutch. (rarely) LOL

Whelp, the chemistry of the catalytic reaction is real. How well it works in reality is a different question.

DEF is a 32.5% solution of urea, When it is injected into the hot exhaust gas stream, the water evaporates and the urea thermally decomposes to form ammonia and isocyanic acid.

The isocyanic acid hydrolyses from the water vapor to carbon dioxide and ammonia. From this point, ammonia, in the presence of oxygen and a catalyst, reduces nitrogen oxides.

I worked on developing the second generation of car catalytic converters when I worked at DuPont.

My 273 has ported heads, polished closed chambers and thin head gaskets. It likes pump gas I guess. Pretty efficient.

Ya, what he said! You amaze me Dave!
