Car Health Score: What Your 0-100 Rating Really Means (SKANYX Guide)

Your SKANYX app just gave your car a health score of 72. Is that good? What does it mean? Should you be worried?

SKANYX's Health Monitor is the only diagnostic tool that gives your car a simple 0-100 health score. This guide explains what that number really means and what you should do about it.

What Is Car Health Score?

Simple Explanation: Your car's health score is a single number (0-100) that represents your vehicle's overall condition. Think of it like a credit score for your car—higher is better. How SKANYX Calculates It:

• Analyzes 40+ vehicle modules
• Monitors sensor readings over time
• Compares to normal operating parameters
• Factors in wear patterns and degradation
• Generates a single score from 0-100

Key Point: The health score is a snapshot of your car's condition right now. It updates every time you scan with SKANYX.

Understanding the Score Ranges

70-100: Healthy (Green Zone)

What It Means:

• Your car is in good condition
• All systems operating normally
• No immediate concerns
• Continue regular maintenance

What to Do:

• Keep up with regular maintenance
• Scan monthly with SKANYX to monitor
• Address any minor issues promptly
• No urgent action needed

Example Scores:

• 90-100: Excellent condition, like new
• 80-89: Very good, minor wear
• 70-79: Good condition, normal for age/mileage

Real-World Meaning: A score of 85 means your car is in very good condition. Most systems are working well, with only minor wear expected for the vehicle's age.

40-70: Fair (Yellow Zone)

What It Means:

• Some systems showing wear
• Issues detected but not critical
• Maintenance needed soon
• Monitor closely

What to Do:

• Review SKANYX recommendations
• Address identified issues
• Plan repairs within 1-2 months
• Increase scan frequency (bi-weekly)

Example Scores:

• 60-69: Fair condition, some issues
• 50-59: Below average, multiple issues
• 40-49: Poor condition, significant problems

Real-World Meaning: A score of 62 means your car has some problems that need attention. Not urgent, but should be addressed soon to prevent further decline.

0-40: Critical (Red Zone)

What It Means:

• Serious problems detected
• Immediate attention required
• Risk of breakdown or damage
• Expensive repairs likely

What to Do:

• STOP driving if score is below 20
• Get professional inspection immediately
• Address critical issues ASAP
• Scan daily until issues resolved

Example Scores:

• 30-39: Critical condition, major problems
• 20-29: Very critical, breakdown risk
• 0-19: Extremely critical, do not drive

Real-World Meaning: A score of 35 means your car has serious problems. You should get it inspected and repaired immediately. Continuing to drive could cause more damage.

Interpreting Your Score

Score by Vehicle Age

New Car (0-2 years):

• Expected: 85-100
• Below 80: Issues detected
• Below 70: Significant problems

Mid-Age (3-7 years):

• Below 55: Normal wear, but monitor
• Below 45: Significant issues

Key Point: Health score accounts for vehicle age and mileage. A 10-year-old car with a score of 65 might be in better condition than a 3-year-old car with a score of 55.

Score by Mileage

Low Mileage (<50,000 miles):

• Expected: 80-100
• Below 75: Early issues detected

Medium Mileage (50,000-100,000 miles):

• Expected: 70-85
• Below 65: Wear showing

High Mileage (100,000+ miles):

• Expected: 60-75
• Below 55: Significant wear
• Below 45: Major issues
