SHIPPING POLICY
Drive On Diesel ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Drive On Diesel only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.
The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.
Drive On Diesel provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.
Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".
If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.
As is the case for the majority of the diesel products sold on Drive On Diesel, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Drive On Diesel will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.
What is a Core Charge?
A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.
30 Day Core Charge Hold
You authorize Drive On Diesel, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.
The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Drive On Diesel offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Drive On Diesel core charge presented to you online today with your item is representative of the most common core charge.

Diagnosing fuel injector problems early can save you from costly repairs and maintain your vehicle’s efficiency. In this blog, we'll outline the steps to diagnose fuel injector problems, using relevant keywords to enhance your SEO strategy.
Diagnosing fuel injector problems involves several steps and observations:
-
Engine Misfires
-
One of the most common symptoms of faulty fuel injectors is engine misfires. If you notice your engine misfiring, especially during acceleration, it could indicate a problem with one or more injectors.
-
-
Poor Fuel Economy
-
A sudden drop in fuel efficiency often points to fuel injector issues. Clogged or leaking injectors can cause the engine to use more fuel than necessary, leading to decreased fuel economy.
-
-
Rough Idling
-
If your engine idles roughly or stalls frequently, it may be due to inconsistent fuel delivery from a malfunctioning injector.
-
-
Check Engine Light
-
Modern vehicles are equipped with sensors that monitor the performance of various components, including fuel injectors. A check engine light on your dashboard can indicate injector problems. Using an OBD-II scanner can help pinpoint the exact issue.
-
-
Fuel Smell
-
A strong smell of fuel, especially around the engine or exhaust, can indicate a leaking injector. This not only affects performance but also poses a safety hazard.
-
-
No Start Condition
-
In severe cases, faulty fuel injectors can prevent the engine from starting altogether. This is often due to a complete lack of fuel delivery to the combustion chamber.
-
-
Visual Inspection
-
Inspecting the fuel injectors and the surrounding areas for signs of fuel leaks, cracks, or damage can help identify physical problems.
-
In conclusion, diagnosing fuel injector problems is crucial for maintaining your vehicle’s performance and fuel efficiency. Symptoms such as engine misfires, poor fuel economy, rough idling, a check engine light, fuel smells, no start conditions, and visual damage can all point to injector issues. By incorporating keywords like "fuel injector problems," "engine misfires," "poor fuel economy," and "check engine light" into your diagnostic routine and research, you can better understand and address these issues. Early diagnosis and intervention will help keep your engine running smoothly and efficiently.
A cylinder balance test, resistance check, or flow bench test can help confirm injector health.
