Remember: marketing departments often influence those manuals to promote “low cost of ownership.” That doesn’t mean the factory intervals are ideal if you plan to keep your vehicle running strong for 300,000 miles.
Please keep a detailed log of your maintenance. At a minimum, save all invoices in an organized manner so you can easily reference past work.
The table below lists realistic, longevity-focused recommendations—along with the intervals I personally follow on my own vehicles.
| Components | Interval | Notes |
|---|---|---|
| Brake Fluid | 3–5 Years | |
| Comprehensive Inspection | 6 Months / Best to do at every oil change | |
| Coolant | 50k / 5 Years | |
| Differential / Transfer Case | 30k | Use manufacturer’s fluid |
| Oil / Oil Filter | 5k / 6 Months | |
| Power Steering | 50k–70k Miles | |
| Spark Plugs | 100k Miles / 10 Years | Use manufacturer’s plugs |
| Transmission Fluid | 60k / 6 Years | Use manufacturer’s fluid |
