Honest, Reliable, Great Service. I am in L.A. and needed someone to sell me two new batteries and install and start a Peterbilt Truck for me in Sacramento with me not present. I found Capital Diesel on Yelp and they exceeded all my expectations. It's nice to take a chance and have it work it out perfectly. Good company, gets the job done on time and within budget.
