I've read that Shell V-power 91 has NO ethanol, is that correct?
When I had my BMW I got a Vishnu tune and they told me that Shell gas dynoed 10 extra HP compared to other brands.
My car is turboed, and soon I'm going to go for more power, push things a little more, and I want to find the best gas I can get consistently.
Is it true that in CA gas can be different from station to station even with the same brands?
