3.2 tests finished with different octanes.
Ok i finished my test with 6 tank fulls of 87,89,91. All the driving was intown so this way is was a fair test.
Best avg gas mileage was 20 with 89 octane.
2nd best was 18 with a tie between 87,91 octane.
Best mid and wot respond was 91 hands down and 87 was the worst.
Our group is going to T&T in the 1/8mile with there srt8 and i will also join in using 98 octane just to keep the pcm from pulling timing as this way the little 3.2 engine will be running all the timing it was designed with. There will be another thread on the T&T outting. Other states gas is way better than ca as were limited to 1.8% oxy in all 3 octanes on the west coast and all other states have 3.5% oxy in theres.
