The Complete Cars & Trucks Maintenance Guide
This guide covers maintenance schedules for gas, diesel, and hybrid cars and trucks. Whether you drive a daily commuter, a family SUV, a work truck, or a weekend vehicle, select your powertrain type below and we'll show you what's due. We cover oil and filter changes, brake pad and rotor service, tire rotations, coolant flushes, transmission fluid, spark plugs, air and cabin filters, battery health, and seasonal prep. For diesel trucks, we include DEF fluid, fuel filter, and turbo-specific maintenance. For hybrids, we cover the high-voltage battery system, regenerative braking, and the interplay between electric and gas drivetrain service.

Engine Oil & Filters
Clean oil is the single most important thing you can do for your engine's longevity.
Log Every Oil Change
Build a complete service history. Know exactly when your last change was and what oil you used.
Brakes
Your braking system is safety-critical. Inspect regularly and never ignore warning signs.
Tires & Alignment
Four contact patches keep you on the road. Proper tire care improves safety, fuel economy, and ride quality.
Battery & Electrical
A healthy battery and electrical system keep everything working reliably.
Seasonal Preparation
A few minutes of prep each season prevents costly problems year-round.
Winter Prep
- Check battery health before cold weather
- Inspect coolant strength and level
- Switch to winter tires if applicable
- Check wiper blades and washer fluid
- Test heater and defroster operation
Summer Prep
- Check A/C operation and refrigerant
- Inspect coolant level and condition
- Check tire pressure (heat increases PSI)
- Test battery; heat degrades batteries faster than cold
- Inspect belts and hoses for cracking
Towing Season
- Check transmission fluid before towing
- Verify trailer brake connections
- Increase tire pressure per load specs
- Service differential fluid if overdue
- Monitor engine temperature while towing
Long-Term Storage
- Fill fuel tank and add stabilizer
- Connect battery tender
- Inflate tires to max recommended PSI
- Change oil before storage
- Cover vehicle or park in dry area
