I'm an ultimate creature of habit so I always fill my truck when it gets to half a tank. I go to the same Chevron at literally the same pump so long as it's not taken (yes, I'm OCD). I typically use their 91 octane, about 15+ gallons which always puts me around 415-425 DTE at my consistent 13.5 mpg.
Soooo, I filled my half tank today but I used their 89 octane and noticed my DTE was only 390. I couldn't find any satisfactory answers yet so just wondering if anyone else experience this phenomenon?
Just seems weird I lost 20+ DTE and the only thing different I did is use a lower octane gas. My pea brain hurts, please help.
