Opening Hook: Is Diesel Engine Deletion Worth the Risk to Your Warranty?
Diesel engine deletion warranty has become a hot topic among diesel truck owners and enthusiasts. The practice of removing or “deleting” engine components related to emissions—such as the Diesel Particulate Filter (DPF)—promises improved performance and fuel efficiency, but sparks questions about warranty coverage and legal risks. Is diesel engine deletion worth the potential risk of voiding your warranty? In this article, we investigate this controversial modification, highlight key warranty insights, and share expert advice from Mark May of Advantage Warranty Group.
Overview of Diesel Engine Deletion and Its Effect on Warranty Coverage
- Definition of diesel engine deletion and common modifications: Diesel engine deletion refers to removing or bypassing emission control devices like the DPF, SCR (Selective Catalytic Reduction) system, and EGR (Exhaust Gas Recirculation). These deletions are often done via aftermarket delete kits to enhance engine efficiency or reduce maintenance costs.
- Typical warranty coverage for diesel trucks before deletion: Manufacturer warranties usually cover engine and drivetrain components under strict conditions — any unauthorized modifications, especially emission-related deletions, typically risk voiding factory warranties.
- Mark May of Advantage Warranty Group explains how deletion affects warranty claims: According to Mark May, "Because of the fact that we don't fear diesel deletion, we no longer deny claims as a result of that." This represents a significant shift in how warranties can accommodate modified diesel trucks.

Understanding Diesel Truck Warranty Policies on Deleted Trucks
- How warranty providers view deleted trucks: Traditionally, warranty providers viewed deleted trucks as high-risk, often rejecting claims related to engine and drivetrain failures after modifications.
- Coverage of aftermarket parts such as delete kits and lift kits: Modern warranty plans, like those offered by Advantage Warranty Group, can extend coverage to trucks with aftermarket modifications—including delete kits and lift kits—delivering flexibility unseen in OEM warranties.
- Mark May’s insight: “We no longer deny claims due to diesel deletion, ensuring coverage remains intact.”
Common Concerns: Does Deleting Diesel Void the Warranty?
- Legal and manufacturer perspectives on diesel engine deletion: Manufacturers warn diesel deletion violates emissions standards and can void factory warranties. Additionally, legal risks arise from violating Clean Air Act regulations. However, the extent to which warranty is voided depends on how deletion is detected and claims are handled.
- Risks of being caught with a deleted truck: Beyond warranty issues, owners risk fines and legal consequences if vehicles are inspected and found with emission system deletions.
- Clarification on removing emission components like DPF and its warranty implications: While DPF removal typically leads to voided factory warranty coverage, some extended or aftermarket warranties cover deleted trucks, minimizing claim denial risk.
Mark May, of Advantage Warranty Group, states, “Because of the fact that we don't fear diesel deletion, we no longer deny claims as a result of that.”
The Role of Delete Kits in Diesel Trucks and Warranty Coverage
- What is a delete kit and how it modifies diesel trucks: Delete kits remove emissions equipment from the exhaust system allowing the engine to run without emission control filters, potentially improving performance and reliability with less maintenance.
- Impact on drivetrain and engine components: While deletions can reduce backpressure and improve exhaust flow, concerns remain about engine longevity and possible increased wear without emissions controls.
- Warranty coverage considerations for trucks with delete kits: Advantage Warranty Group and similar providers offer specific warranty plans accommodating delete kits, ensuring trucks stay protected even after modification.

- Regional trends such as in the Deep South: Diesel engine deletion is particularly popular in regions like the Deep South, where emissions enforcement may be less rigid and the culture embraces truck modifications.
- Mark May’s perspective on the efficiency and customer demand for deleted trucks: Mark notes growing customer demand and acceptance among warranty providers, stating, "The engines typically run more efficiently without all those regulations."
