National Petroleum in San Ramon (1990 San Ramon Valley Blvd)

USE CAUTION WITH THIS STATION FOR DIESEL. Pump and outdoor advertising state “Diesel #2”, which is Diesel with under 2% bio content. However the pump also has a sticker which says 5 to 20% bio content. They are dispensing BIO diesel and not Diesel #2!!!!! False advertising and bio diesel can cause engine damage in some manufacturers vehicles.

Diesel is 5 to 20% biodiesel. Check your owners manual if that will hurt your engine before you fill up.

Excellent customer service

Look clean. Easy accessible to pumps. 6 pumps and they have diesel.

They have the best price in the town

If you’re looking for Diesel #2, this isn’t your station. They sell B20 bio-diesel. My Mercedes can’t use that

Diesel warning: it's B20 here (20% biodiesel) which is why it's the cheapest around. Most diesel consumer vehicles made since 2007 require #2 diesel (aka B5) and using B20 could invalidate a warranty, and you'll have no claim against the station because they don't advertise it as #2 or B5. Sticker at pump notes it's B20 or up to 20% BioD.

Be aware of Bio Diesel Can harm some engines GM says not to use.

Wow...GasBuddy just found me the cheapest gas in my town. I can't believe I downloaded this amazing app just today. Thank you GasBuddy.

20% biodiesel YIKES! Don't be fooled by the low price! I was really low and filled up by mistake. My mechanic said ok once in a while but add diesel #2 as soon as you can. There is no option on gas buddy to warn people! BEWARE!
