- JTJesus TorresOct 7, 20265.0When you think of gas stations you think of mobile, shell, Costco, or Sam’s. Let it be that way so I can keep my beloved Sinclair. I was down to my last 25 dollars and didn’t expect much gas from anywhere but then the sign with a big green dinosaur and red letters over is reading “Sinclair” shined down in front of me like it was promising salvation. With 25 dollars in this economy there’s not a lot you can get with it, but Sinclair didn’t think that way. With those 25 dollars I got half a tank of gas and was good for the next few days. Sinclair shouldn’t be associated with the evil red letters and should be turned to gold letters to show the beauty I saw and felt when Sinclair saved me.
- MMMousa MousaSep 1, 20265.0It is truly the best.
- ALandrew labibSep 1, 20265.0Great gas station! The place is always clean and well maintained, and the staff is friendly and helpful. Service is quick, the pumps are easy to access, and I’ve always had a good experience whenever I stop by. Definitely a convenient and reliable place to get gas. Would recommend!
- PVPUMAS*U*FAMILY VelezAug 16, 20265.0Good service nice staff
- COCrystal OlveraJul 6, 20265.0I’m loving this new ownership! I use to go to Shell bc it was so affordable and clean, back in the day also surprisingly safe in this area but they have let their business go- it’s terrible. I’m grateful that Sinclair has opened up and has working credit/debit tap machines at the pump! It’s safe for me as o have my infant in the car and cannot go inside to use the machine. It is very clean and affordable! Thank you for having clean, working gas pumps and affordable gas prices! Keep your standards of cleanliness and working pumps HIGH.
