My own 2015 RCF. Been running full E85 since January 2021. Hasn't had any issues. Been a super reliable daily driven car while pumping the most affordable, highest octane, and best quality consistent fuel available at the pump, E85.

Contact me to convert your Lexus/Toyota to switch to full E85 safely and avoid paying over $6/gal for Cali 91 octane.
