Petroleum Products


JB Dewar in the vinyards

From fuels, lubricants and filters to coolants, equipment and cleaners, JB Dewar carries only the finest quality petroleum industry products from trusted manufacturers.  Whether you’re troubleshooting, maximizing efficiency or simply restocking, we have a vast array of petroleum and specialty products to meet your needs.


Filters are critical to the life and performance of your engine. A small amount of dirt can create significant engine damage over time. Trapping oil and other contaminants with the appropriate filter – fuel, oil, hydraulic, coolant or cabin air, to name a few – can prevent this damage.  At JB Dewar, we recommend using Baldwin Filters to protect your engine and equipment.




As the leading fuel distributor on the Central Coast, JB Dewar has an extensive selection of petroleum-based products to suit your needs, including:

  • 87, 89, and 91 octane unleaded gasoline
  • Clear & red-dyed diesel
  • Bio-diesel (B20)
  • Renewable diesel
  • Racing Fuels
  • Wholesale bulk fuel delivery
  • Fuel tank sales, rental and equipment

If we don’t have it on hand, we can get it on order. Contact us for more information.


Proper lubrication is key to the health of your engine. Using the correct lubricant can maximize the reliability and life of your equipment.  JB Dewar carries a broad range of high-quality lubrication products.

As a Chevron 1st Source Lubrication Marketer, JB Dewar has met the manufacturer standard of excellence in training, product knowledge and customer support for Chevron, Havoline and Delo* lubrication products. We also offer readily biodegradable, sustainable, USA-made and cost competitive lubrication products from Bio Blend*.

The educated staff at our Dewar Depot locations can assist you in selecting the right products for your lubricant needs.


Diesel Exhaust Fluids

Blue Leaf Diesel Exhaust Fluid

Diesel Exhaust Fluid (DEF) is a high-purity solution of urea in deionized water, used to chemically reduce NOx emissions from trucks and buses powered by diesel engines.

DEF is highly susceptible to contamination – less than a teaspoon of impurities can render a 6,500-gallon tank useless – so the handling process is extremely important.

JB Dewar is pleased to offer industry-leading closed-distribution systems, ensuring a contamination-free distribution of product. Our trained Dewar Depot staff will make sure that when you purchase DEF, you have the right advice and instruction on equipment and storage practices. We also carry DEF pumps and dispensing equipment. DEF is available in 2.5-gallon, 55-gallon, 275-gallon and bulk quantities.


Coolants play another important role in your engine’s reliability, ensuring safe temperatures and optimal performance. JB Dewar offers a variety of coolants to meet guidelines specified by the manufacturer, engine or equipment type, including:

  • Chevron DELO ELC – Red, Caterpillar-approved
  • Havoline Conventional Antifreeze/Coolant – Green
  • Havoline Universal
  • Havoline Dex-Cool – Orange, GM-approved
  • Zerex G-05 Antifreeze Coolant – Yellow, approved for newer Ford, DaimlerChrysler vehicles
  • Zerex Asian Vehicle Coolant – Red, compatible with Asian coolants and cooling systems

Coolants are commonly offered in cases of gallons, as well as 55-gallon drums, and many may be purchased either pre-mixed or concentrated. Nitrite and silicate-free extended life options are available.  Consult our team at the Dewar Depot for more information.
