2026 Ford Super Duty: Lakeland Service & Repair Guide

What actually covers a new Super Duty

This is the single most important thing to know before buying: Lakeland Ford's well-known Nationwide Lifetime Warranty program, which covers most of the dealership's other new vehicles for as long as the original owner keeps them, specifically excludes Super Duty, diesel, commercial, fleet, and business-use vehicles. A new Super Duty relies on Ford's factory coverage instead — 3 years/36,000 miles bumper-to-bumper, 5 years/60,000 miles powertrain, and a longer 5-year/100,000-mile warranty specifically on the Power Stroke diesel engine and its major internal components. That diesel-specific extension exists because Ford expects — correctly — that these engines rack up miles faster than a typical gas engine's warranty period assumes. Buyers cross-shopping Super Duty against a Lifetime Warranty-eligible F-150 should factor this difference into the decision, not assume the same program carries over.

The Power Stroke maintenance rhythm

Ford's Intelligent Oil-Life Monitor sets the actual oil-change interval per truck based on driving conditions rather than a single fixed mileage number, the same approach used across the Ford truck lineup. Diesel-specific maintenance adds a few items a gas-engine owner won't think about: diesel exhaust fluid (DEF) needs to be topped off between oil changes on trucks doing heavy mileage or towing, and the fuel filters on the 6.7L Power Stroke require replacement on their own schedule, more frequent than a gas truck's. None of this is unusual for a modern diesel — it's simply a different rhythm than a gas F-150 owner is used to, and Lakeland Ford's service advisors can lay out the exact schedule for a specific VIN and configuration.

If DEF ends up in the fuel tank

This is a real, specific risk for diesel truck owners, and Lakeland Ford runs a dedicated emergency response for it. If diesel exhaust fluid is ever accidentally put into a Super Duty's fuel tank, the instructions are simple and urgent: do not attempt to start the truck, secure the keys, and call the dealership's DEF contamination specialist immediately rather than waiting for a normal service appointment. Catching the mistake before the ignition turns to the start position is the difference between a manageable repair and a much larger one — once the engine has run on contaminated fuel, the damage is done. Lakeland Ford backs the repair, when needed, with factory-trained and certified diesel technicians, factory Ford replacement parts in stock, free towing up to 100 miles with a paid repair, a complimentary service loaner during the repair, and direct coordination with the customer's insurance provider, since a DEF contamination repair is often an insurance claim rather than an out-of-pocket expense.

What Florida heat does to a diesel work truck

Central Florida's climate adds its own considerations on top of the normal Power Stroke schedule. A long, hot cooling season pushes AC compressors and refrigerant systems harder for more months of the year than almost anywhere else in the country — worth watching on a truck that may sit idling on a job site with the AC running for hours at a stretch. Afternoon thunderstorms mean tires cycle between dry pavement and standing water constantly, which makes tread depth and rotation intervals matter more here than in a drier climate, especially on a dual rear wheel (DRW) configuration where uneven wear is harder to spot by eye. Heat also shortens battery life broadly — worth factoring in on a truck that, depending on configuration, may run more than one battery to support its electrical demands.

The service team

Lakeland Ford's service department is led by Service Director Dave Knisley, who also serves as the dealership's designated diesel and DEF contamination specialist, alongside Service Manager Chuck Scott and advisors including Gina Hines and Chris Hungerford. Jerry DeBlasio's review of the parts department, after his 2020 F-250 XLT Super Duty diesel needed a mirror, captures the kind of straightforward help Lakeland Ford's Super Duty owners describe: "I then placed the order & called the parts dept they were very pleasant & helpful, so if ure in the need for ford parts Lakeland ford is the place to go." Gavin Baulac's review, about a different Lakeland Ford truck purchase, put it simply: "I've also been using their service department for years and they have always been great."

Frequently asked questions

Does the Nationwide Lifetime Warranty cover a Super Duty?

No — Super Duty, diesel, commercial, and fleet vehicles are specifically excluded from Lakeland Ford's Nationwide Lifetime Warranty program. A new Super Duty is covered by Ford's factory warranty instead, including an extended 5-year/100,000-mile warranty on the Power Stroke diesel engine.

What should I do if I accidentally put DEF in my fuel tank?

Do not start the truck. Secure the keys immediately and call Lakeland Ford's DEF contamination specialist right away rather than waiting for a scheduled appointment — catching the mistake before the ignition reaches the start position can prevent catastrophic fuel-system damage.

How often does a Power Stroke diesel need service?

Oil-change intervals follow Ford's Intelligent Oil-Life Monitor rather than a fixed number, but diesel owners should also budget for periodic DEF top-offs and fuel-filter replacement on their own schedule, both more frequent maintenance items than a comparable gas truck requires.

Is Florida heat actually harder on a diesel work truck?

The AC and battery considerations apply to any vehicle in Central Florida's climate, but they matter more on a truck that may idle for extended periods on a job site or tow heavy loads through summer heat — both put additional strain on the same systems.

How do I schedule Super Duty service in Lakeland?

Through Lakeland Ford's service and parts specials page, or by calling the service department directly for anything urgent, including a suspected DEF contamination issue.

Keeping a Super Duty running through Central Florida summers

A diesel work truck asks for a slightly different maintenance rhythm than a gas half-ton, and knowing the Lifetime Warranty exclusion upfront — plus having a specific plan for DEF contamination and Florida's climate demands — is what actually keeps a Super Duty out of the shop for anything unplanned.
