Sodium filled valves cool much better, in the racing community, we call those "Saltshaker Valves". Started out on WWII era air cooled aircraft engines, then gravitated to the air cooled motorcycle world. In the 30's, Mercedes actually experimented with Mercury filled valves!!!😎I run 87, 90% of the time.
I also voted with my wallet trading my 2017 3.2 on a 2019 2.0T.
Words such as highly stressed dont tell the whole picture the 3.2 doesnt have sodium filled exhaust valves for example.
If I put helium in my tires will my Cherokee be lighter, have better ground clearance, and go faster??
Sorry, just busting some b**ls...

Not to mention plasma coated rings, sand cast block, and liquid cooled intake and exhaust. I feel I got my moneys worth. I can detect no seat of the pants difference in performance between 89 and 91. I don't know what the HP would be for the 2.0 if there was no turbo charghing. Coming from a 2.4 Cherokee, I detect no performance difference between my 2.4 and the 2.0 when not in boost mode, which is quite often with my commuting area.Words such as highly stressed dont tell the whole picture the 3.2 doesnt have sodium filled exhaust valves for example.
No thanks, those things only go straight!!! I'm like 6-0 by a mile on the road course against those, and like 3-1 in the 1/8 mile, and that loss was because the guy was running slicks, and he only beat me by 0.2...Demons do put on a great smoke show though...LOL!!!😎🏁You could have got a Dodge Demon!
Since your entire argument seems to be based on gas grades -- and on a distorted conception of the octane requirements of the 2.0T at that -- no wonder this thread refuses to die. "It doesn't matter what the turbo engine may have going for it; I've heard that you have to use that nasty high-octane jet fuel whether you like it or not!"Let me get this straight-if the weather is hot premium is recommended/ if I am going to tow, premium is recommended/if I am going to put a luggage pod on top, premium is recommended/ If I am going off road, premium is recommended...
Please continue to show your great knowledge instead of guessing about everything related to octane and the turbo engine.'This increase in performance is most noticeable in hot weather or other heavier load conditions, such as while towing'

What do I do if I want to all of the above while the weather is hot-put in race fuel , Ut-Oh, what if I am leaving someplace cold going to some place hot. ????
