I noticed my owners manual doesn't recommend fuel with alcohol but that's all that's available in California. What do you guys think of this? Are all the refiners putting about the same amount of alcohol in? I understand Chevron here is using 5.7% by volume.

 

i dont know anything about the gas here but if thats what the trucks need, im sure they will do fine since the trucks are sold here. sort of like how they have to do extra mods for the ca emissions. i dont think they do anything different to the engines though.
