3 M.P.G Test 87,89,91 Octane

Well at 1st with just 45 miles on it we had 87 octane and it seen to have a shudder on take off so the next tank i tried 91 octane and the shudder went away then the next tank was 89 and the shudder was still gone. Now to be fair i tried to do the same driving i did with both my srt8. Now on 87 & 89 i did a 80 mile trip on freeway and the 91 i didnt so this time around i get that same trip in for the 91 to be fair. Now on my 2nd tank of 87 the shudder is gone lol so it must of been the added mileage lol. I now have 700 miles so this 87 octane just might be better than 1st tank. Heres how the mpg went and all readings were done manually. My dd wt is 4495 with 1/4 tank of gas. I did look into the wt diff on the diff models with the 3.2 engine and 2 whd w/out driver and 1/4 tank gas from the factory and it was 3771 lbs and my trailhawk was 4250 lbs. w/out driver and thats 479 lbs diff.
1st tank 87 = 18.80.
2nd tank 91 = 17.26.
3rd tank 89 = 20.38.
