What is red dyed diesel and when should I use it?
Red dyed diesel is tax-exempt fuel designated for off-road use only, including construction equipment, excavators, generators, and other non-highway machinery. It cannot be used in vehicles that operate on public roads.
What are your minimum and maximum order quantities?
We accommodate orders of all sizes, from single equipment fills to bulk deliveries of up to 10,000 gallons. Contact us for volume pricing and custom solutions for large projects.
Do you deliver to active construction sites in Utah County?
Yes! We deliver to job sites throughout Utah County, Salt Lake County, and Davis County. Just provide the site address and access instructions when requesting a quote.
How quickly can you deliver fuel for emergency situations?
We offer 24/7 emergency fuel delivery. For urgent requests, call us at (801) 900-3715 for same-day or next-available delivery to prevent equipment downtime.
Can you set up recurring deliveries for ongoing projects?
Absolutely! We offer scheduled deliveries for long-term projects and can monitor your fuel levels to ensure you never run out during critical construction phases.
Do you deliver to remote or hard-to-access job sites?
Yes! Our drivers are experienced in navigating active construction zones, remote sites, and challenging terrain. Just provide clear access instructions and any special requirements when placing your order.
What safety measures do you follow for on-site fuel delivery?
All our drivers are professionally trained in safe fuel handling and follow strict safety protocols. We comply with OSHA regulations, use proper grounding techniques, and carry comprehensive insurance for all deliveries.
Can you fuel multiple pieces of equipment at once?
Yes! We can efficiently fuel multiple pieces of equipment during a single visit using wet hose delivery. This is perfect for equipment yards or large job sites with multiple machines that need fueling.
Do you offer fuel tank rentals for long-term projects?
Yes! We provide both short-term and long-term fuel tank rentals to keep fuel on-site. This is ideal for projects that need consistent fuel access without repeated deliveries.
What payment methods do you accept?
We accept all major credit cards, purchase orders from established companies, and can set up invoicing for recurring clients. Payment terms can be discussed for large commercial accounts.
