Buy it in 5 gallon buckets its cheaper or 55 gallon drums way cheaper


Mixing E85 with 93 works to. I only know 1 place with e85 and thats about 25min away.

mixing 10% only gives you an octane rating of 92.8
mixing 20% only gives you an octane rating of 93.6
mixing 30% only gives you an octane rating of 94.4
