Top 10 Gas Stations & Cheap Fuel Prices in Diamond Bar, CA

Always my go to gas station whenever I'm near by. Cheapeat price ever

machines get hacked wayyyy too often. Frauded too many times. will never come back

I’ve been a local to the area for more than 20 years. I have seen this gas station take advantage of customer prices since the post-pandemic time. It seems at moments they price their fuel somewhat decently and at other times it’s absolute robbery. I do not believe it is solely current market crude oil prices because other chevrons are much different. They are jacking up prices as if some major development is happening around the area and that is not the case. Gas stations like this is what inflates the price of fuel and cost of living in Southern California. The next proposition on a ballot to regulate gas station price gouging will get my vote. But I like to vote with my wallet, so they will no longer get my business.

This place is typically cheaper than others in this area and it is the same price for cash or credit which is nice. Ran into a few homeless beggars here though.

BEWARE!!! The cash price on the sign ONLY applies if you get a car wash. If not, you can pay cash but it will be the credit card price.

Very clean station and friendly cashiers

over priced gas

Stocked up on whatever you need when your on the go and clean

Prices both cash and credit consistently higher than the other Mobil 1 mile down the street (Diamond Bar Blvd and 57 North on ramp) and 3 miles away in Chino Hills

Good place to pump gas Right off the freeway
