They have a lower octane rating but ive been reading on a bunch of forums saying that guys running chevron 94 are getting alot of knock issues and have started going down to the states to fill up with 92 and get less knock on the 92.
From a tuner stand point ive read that our 94 tunes like California 91.
Just interesting overall...I thought a octane rating was a octane rating and it was all the same.
Just trying to see if any tuners have found less issues with lesser octane rated fuels locally or if a "local 94" tune is in need.
