National Petroleum in Sunnyvale (603 Old San Francisco Rd)

This station owner might be a cheater by selling you less gasoline with a uncalibrated pump. That's why the gas price is as low as Costco. Someone reported pumping 23 gallons into 20 gallons tank. After complaining, he reimbursed $10.

Pumps are out of calibration resulting in charging for gas not delivered.

Worst gas station ever. Pumps are beyond slow and they don't shut off so you over flow your car

Price is posted as low as Costco but they cheat by adding more gallons on pump meter so that you eventually pay more. I used to pump 11 gallons at other stations but it showed 15 gallons!!!!!

1:30 to pour one gallon. CHEATED me. Kept fake pouring gas when my tank was 10000000% full. Do NOT go here. Seriously!!

Gas pump is too f*king slow

Cheap gas yesssss love it

This is good quality gasoline at the best prices in Sunnyvale. I use my Gas Buddy charge card to save 5 cents per gallon and be 269 9

National petroleum 603 Old San Francisco Rd I am Manager here. Just let's You Know Cash & Credit Card. Come In fill up the tanks....

Seem to have completely fixed the problems reported earlier this year: My fill-up came to a reasonable amount, not more than my gas tank volume. Pump flow speed was good. County Weights and Measures seal has this year's date. Price just a few cents more than Costco, worth not having to wait. Credit price same as cash. This station has fully redeemed itself and is back in my good graces and on my "okay" list.
