2020 Giulia TI
Usually when I fuel up I either pump myself (yes I know it's Jersey) or at least get out of the car to make sure the attendant doesn't drool gas on the body. At my usual Shell station yesterday I just told the new youngish attendant to fill with V Power. When I got home I looked at my receipt and saw that she had pumped 11.5 gallons of REGULAR! Now I'm worried what effect this will have. I have an approx 150 mile trip coming up and will refill with 93 after this. Hoping this will raise the average octane to a reasonable level. Or should I add a bottle of octane booster before I drive? Looking for advice.
