What Cadillac actually publishes, what it does not, and why the Blackwing is not on this schedule.
Cadillac recommends an oil and filter change and a four-tire rotation every 7,500 miles, and it gives new owners the first scheduled service visit at no additional charge. Beyond that, the intervals below are what Cadillac publishes for its vehicles, and there is one honest caveat we are going to make at the top rather than bury: they are brand-wide guidance, not a CT5 schedule. Cadillac points owners to the Owner’s Manual and the myCadillac app for the schedule that applies to a specific car.
We publish them anyway, because they are what the manufacturer publishes and they are what you asked for. What we will not do is invent a CT5-specific table from a service blog and present it as gospel, and we will not put the CT5-V Blackwing on the same calendar as a four-cylinder sedan. Our service department is at Covert Cadillac Bee Cave and reaches you at (512) 861-0603.
The Intervals
| Service | Cadillac’s Recommended Interval |
|---|---|
| Oil and filter change | Every 7,500 miles |
| Four-tire rotation | Every 7,500 miles |
| Engine air filter | Around 12,000 to 15,000 miles |
| Cabin air filter | About two years, or around 22,500 to 24,000 miles |
| Brake inspection | From 12,000 to 30,000 miles, and immediately on any squeal |
| Wiper blades | Inspect seasonally |
Cadillac’s brand-wide maintenance guidance. The Owner’s Manual and the myCadillac app govern your specific vehicle.
The Basics
Every 7,500 miles for an oil and filter change, and every 7,500 miles for a four-tire rotation, which is why the two are done on the same visit and why your first one is free. The engine air filter comes due somewhere around 12,000 to 15,000 miles — doing it with every other oil change is a reasonable habit. The cabin air filter runs about two years, or around 22,500 to 24,000 miles, which in a climate that coats everything in caliche dust off the Y at Oak Hill is a figure worth taking seriously rather than ignoring.
Brakes get inspected from 12,000 miles onward, and immediately if you hear a squeal. Do not wait for the next oil change to mention it.
The Big Ones
| Service | Cadillac’s Recommended Interval |
|---|---|
| Brake pads and rotors, first replacement | Between 40,000 and 60,000 miles |
| Coolant flush | Around 60,000 miles |
| Battery replacement | About four to five years, generally around 60,000 miles |
| Shocks and struts inspection | Between 60,000 and 75,000 miles |
| Belts and hoses | Inspected and possibly replaced by about 70,000 miles |
| Transmission fluid inspection | Around 70,000 miles |
| Spark plug replacement | About 100,000 miles |
| Differential service | Inspected as the odometer approaches 100,000 miles |
Cadillac’s brand-wide guidance. Whether this engine uses a timing belt or a timing chain is not stated on the manufacturer’s maintenance page, so we do not state it either — ask a service advisor, who will look it up rather than guess.
Where It Differs
The CT5 and the CT5-V share a body, and broadly they share an ownership story. The CT5-V Blackwing does not. A supercharged 6.2L V8 with available carbon ceramic brakes and, in the Precision Package, Michelin Pilot Sport Cup 2 R tires is a different machine to keep, and a single lapping day at a circuit compresses intervals that a commute would stretch across a year. We could not verify a Blackwing-specific schedule from Cadillac, and we are not going to write one for them.
If you own a Blackwing, or you are about to, read the Owner’s Manual for your car and then come talk to our service advisors before you plan around any figure on this page. That is not a hedge. It is the difference between a brake job and a brake failure.
Coverage
| Coverage | Term |
|---|---|
| Basic (bumper-to-bumper) | 4 years or 50,000 miles, whichever occurs sooner |
| Powertrain | 6 years or 70,000 miles, whichever occurs sooner |
| Included maintenance | The first scheduled service visit at no additional charge |
Four years or 50,000 miles of basic coverage, six years or 70,000 miles on the powertrain. Cadillac’s included maintenance is one visit, not a program — a distinction some brochures blur. A pre-paid maintenance plan is offered separately, and whether it pays depends entirely on how many miles you drive.
Budget
A CT5 on the 7,500-mile cycle sees the shop roughly twice a year at typical Central Texas mileage, and the first of those is free. The costs that surprise people are further out: coolant around 60,000 miles, the first brake service between 40,000 and 60,000, and a battery at four or five years. Long, hot summers are hard on batteries and on coolant, and a car that lives on the road out to Spicewood and back will reach those numbers sooner than the calendar suggests.
Fuel is the other line. A rear-drive CT5 is rated 26 mpg combined; a Blackwing is rated 15. The engines and performance page lists every configuration.
Buy Local
We are at 16501 Sweetwater Village Dr, Building 2. Service reaches us at (512) 861-0603, and parts at (512) 920-3910. Certified Service technicians, GM Original Equipment parts, and an advisor who will tell you when a service is not due yet. Customers bring cars in from Barton Creek, from Buda, from Manchaca and down from Spicewood, and the ones who keep to the interval are the ones who are still driving the car at 100,000 miles. Schedule service, visit the service center, or order parts.
Questions
Cadillac recommends an oil and filter change every 7,500 miles, and a four-tire rotation on the same visit. Your car’s oil life monitor and your Owner’s Manual govern the specific vehicle, and hard driving shortens the interval.
Cadillac includes the first scheduled service visit at a participating dealership at no additional charge. It covers an oil and filter change, a four-tire rotation and a multi-point inspection. Everything after that is on you or on a pre-paid plan.
Four years or 50,000 miles of basic coverage and six years or 70,000 miles of powertrain coverage, whichever occurs sooner in each case.
We are not going to tell you it does. We could not verify a Blackwing-specific schedule from Cadillac, and a supercharged V8 with optional carbon ceramic brakes and Cup 2 R tires does not service on the same calendar as a turbocharged four-cylinder sedan. Track use changes it again. Read the Owner’s Manual for your specific car, and talk to our service advisors before you plan around any number on this page.
Cadillac expects the first major brake service, pads and rotors, between 40,000 and 60,000 miles. Brakes should be inspected from 12,000 miles onward, and immediately if you hear a squeal.
No, and this matters. The intervals above are Cadillac’s brand-wide maintenance guidance. Cadillac directs owners to the Owner’s Manual and the myCadillac app for the schedule that applies to a specific vehicle. We publish the brand guidance because it is what Cadillac publishes, and we tell you what it is rather than dressing it up as a CT5 schedule.
