A follow up to Han’s previous thread. I did some research online on what is the best 93 octane gas for our cars and what gas station provides it. My findings, after reading different information on the web was Shell V Power is the best. I compared it to Sunoco which sponsors Nascar and Shell which sponsors Ferrari F1 for many years now. The feedback on everything on the web is Shell V Power Wins.
The issue was where I live, Shell V Power goes for around 3.40/gallon and Sunoco 93 goes for around 3.20/gallon. So I signed up for the Shell Gas Card!! You get around 10 cents of a gallon once you use that card and link it to an APP called Fuel Rewards. Right now Shell V Power due to the Coronavirus issue is down to 3.25/gallon. WIth the Shell card, it brings it to 3.15/gallon, which i think is pretty good. There is annual savings which is marginal, but it RIPs the issue of if you are filling the right Gas.
The word on the web is Shell V Power is better for your engine, in terms out output and mileage. The other gas stations have some quality issues and there is a Shell next to where I live every 1 mile. Please note, the price between the Shell Gas stations vary too. So you can use your cars Nav to find the best Shell, or the Fuel rewards APP.
Best of Luck!!! Could be a bunch of marketing I read on the web, but I think I am sticking with Shell V Power rest of the way.
