Routine Maintenance | Automotive

Following proper maintenance schedules to extend vehicle life and prevent costly repairs.

The Owner's Manual

Your most important maintenance resource.

Section	What You'll Find
Maintenance schedule	When to service what
Fluid specifications	Exact types to use
Tire pressure	Correct PSI for your car
Warning lights	What each light means
Capacities	How much oil, coolant, etc.

Always follow your manual over generic advice.

Maintenance Schedule Overview

Based on Time or Mileage (Whichever Comes First)

Interval	Key Services
Every oil change	Oil + filter, multi-point inspection
15,000-30,000 miles	Air filters, brake inspection
30,000-60,000 miles	Transmission, coolant, spark plugs
60,000-100,000 miles	Timing belt, major services
100,000+ miles	Continued maintenance, more frequent checks

Oil Changes

Why Oil Matters

Function	How
Lubrication	Reduces friction between moving parts
Cooling	Carries heat away from engine
Cleaning	Suspends contaminants
Protection	Prevents corrosion

Oil Change Intervals

Condition	Interval
Normal driving, synthetic oil	7,500-10,000 miles
Normal driving, conventional	3,000-5,000 miles
Severe conditions	Check manual, often 50% of normal

Severe Driving Conditions

Frequent short trips (under 5 miles)
Stop-and-go traffic
Extreme hot or cold
Dusty conditions
Towing or heavy loads
Mountainous terrain

Oil Types

Type	Characteristics	Best For
Conventional	Basic mineral oil	Older cars, simple use
Synthetic blend	Mix of conventional/synthetic	Moderate improvement
Full synthetic	Engineered molecules	Best protection, most cars
High mileage	Added conditioners	75,000+ mile engines

Oil Weight

Common ratings: 0W-20, 5W-30, 10W-30

Part	Meaning
First number (0W, 5W)	Cold viscosity (W = Winter)
Second number (20, 30)	Hot viscosity

Use the weight specified in your owner's manual.

Tire Care

Tire Pressure

Why It Matters	Effect
Underinflated	Poor fuel economy, edge wear, blowout risk
Overinflated	Harsh ride, center wear, less traction
Correct	Best fuel economy, even wear, optimal handling

Check monthly and before long trips. Check when tires are cold.

Where to Find Correct Pressure
Driver's door jamb sticker
Owner's manual
NOT the tire sidewall (that's max pressure)

Tire Rotation

Pattern	When
Every 5,000-7,500 miles	With oil change is convenient

Rotation Pattern	For
Front to back (same side)	Directional tires
X-pattern	Non-directional
Rearward cross	RWD vehicles
Forward cross	FWD vehicles

Tire Wear Indicators

Wear Pattern	Cause
Center wear	Overinflation
Edge wear	Underinflation
One-sided wear	Alignment issue
Cupping/scalloping	Suspension issue
Feathering	Alignment or suspension

Tread Depth

Penny test: Insert penny head-first. If you can see Lincoln's whole head, tires need replacing.

Depth	Condition
10/32"	New tire
4/32"	Consider replacement
2/32"	Legal minimum, replace immediately

Tire Age

Tires degrade with age regardless of tread.

Tire Age	Action
6 years	Inspect carefully
10 years	Replace regardless of condition

Find manufacture date: DOT code on sidewall, last 4 digits = week/year

Fluid Checks

Engine Oil

Step	How To
Park on level ground	Ensure accurate reading
Wait after running	5-10 minutes
Remove dipstick	Wipe clean
Reinsert fully	Pull out again
Read level	Should be between marks
Check color	Golden/amber good, black needs change

Coolant

Step	How To
Engine cold only	Hot coolant pressurized
Check reservoir	Level between min/max marks
Check radiator (if accessible)	Full when cold
Check color	Should be clean, not rusty

Never open radiator cap when hot!

Brake Fluid

Step	How To
Locate reservoir	Usually on driver's side near firewall
Check level	Between min/max marks
Check color	Clear to light yellow (dark = change)
Don't overfill	Pads wear down, level rises

Transmission Fluid

Step	How To
Check manual	Some have no dipstick
Engine running	Warmed up
Shift through gears	Return to park
Check dipstick	Level and condition
Color	Red/pink good, brown/burnt = problem

Power Steering Fluid

Step	How To
Locate reservoir	Usually near engine belts
Check level	Hot and cold marks often shown
Check condition	Clear, not foamy

Windshield Washer

Step	How To
Open reservoir	Usually clearly marked
Fill with washer fluid	Not water (freezes, no cleaning power)
Don't overfill	Leave room for expansion

Filter Replacements

Engine Air Filter

Interval	Notes
15,000-30,000 miles	Or as dirty
Check every oil change	Visual inspection

Symptoms of dirty filter:

Reduced fuel economy
Reduced power
Rough idle

Cabin Air Filter

Interval	Notes
15,000-25,000 miles	More often in dusty/polluted areas
Often forgotten	But easy to replace

Symptoms of dirty filter:

Reduced airflow from vents
Musty smell
Poor A/C performance

Fuel Filter

Interval	Notes
20,000-60,000 miles	Check manual
Many modern cars	Integrated in fuel tank

Brake Maintenance

Inspection Schedule

Interval	What to Check
Every oil change	Visual check if visible
Every 12,000 miles	Thorough inspection
When symptoms appear	Immediately

Brake Pad Life

Driving Style	Expected Life
Highway driving	40,000-70,000 miles
City driving	25,000-40,000 miles
Aggressive driving	15,000-25,000 miles

When to Replace

Sign	Action
Wear indicator squealing	Replace soon
Grinding noise	Replace immediately
Pad thickness < 3mm	Replace
Uneven wear	Replace and investigate

Brake Fluid Replacement

Interval	Why
Every 2-3 years	Absorbs moisture, reduces boiling point
When dark	Has absorbed moisture/contaminated

Transmission Care
