NGE GUIDE

Protecting Your Engine in Sub-Zero Conditions

1. PRE-CHANGE PREPARATION

Ideal Working Conditions

✅ Ambient Temperature: Above -20°C (-4°F) for safe handling
✅ Vehicle Positioning: Sheltered area with concrete floor (avoid snow/ice contact)
✅ Tool Preparation:

Pre-warm sockets/tools to prevent brittleness

Use low-temperature grease on drain plug threads 

Oil Selection Guide

Temperature Range	Recommended FEIBI Oil	Key Benefit
0°C to -20°C	ProSynth 5W-30	Faster cold starts
-20°C to -35°C	Arctic 0W-40	Instant flow at -45°C
Below -35°C	Polar 0W-20	Military-grade cold performance

 

2. STEP-BY-STEP COLD WEATHER PROCEDURE

1. Engine Pre-Warming

Block Heater: 2-4 hours pre-heat (ideal for diesel)

Alternative: Idle 5 mins + drive gently 1km (gasoline)

Never Use: Open flame heating methods

2. Draining Technique

Optimal Oil Temp: 60-70°C (touch test: warm but not hot)

Special Tools:

Magnetic drain plug (prevents thread damage)

Flexible drain hose (avoids splash freezing)

3. Filter Replacement

Pre-Lube Filter: Fill 50% with new oil

Installation Trick:

1. Hand-tighten + ¾ turn

2. Mark with paint pen for visual inspection

4. Refilling Protocol

Oil Warming: Store containers indoors 24hrs pre-use

Pouring Method:

Slow, steady stream

Pause at 80% to check dipstick

 3. POST-CHANGE CHECKS

Critical Verifications

1. Pressure Build-Up:

Start engine → Verify pressure within 3 sec

Diesel: Minimum 15 psi at idle

2. Leak Inspection:

Check drain plug/filter after first thermal cycle

3. First Drive:

Keep RPM <2,500 for first 5km

Monitor temp gauge (should reach 80°C within 10km)

 4. ARCTIC SPECIAL CONSIDERATIONS

Extreme Cold Adaptations (-40°C and Below)

Oil Pan Heater: Mandatory for overnight parking

Double Filtering:

1. Primary full-flow filter

2. Secondary 3µm bypass filter

Storage Tips:

Keep oil in heated storage (+5°C minimum)

Use sealed containers to prevent moisture absorption

Emergency Cold Start Kit

FEIBI Arctic Primer Spray

Magnetic Oil Pan Warmer

Insulated Dipstick (prevents freezing)

 5. MAINTENANCE SCHEDULE ADJUSTMENTS

Condition	Interval Adjustment
Consistent -20°C	Reduce 25% from normal
Short Trips <5km	Change 2x more frequently
Frequent Cold Starts	Use FEIBI ColdStart additive

 

6. TROUBLESHOOTING COLD-WEATHER ISSUES

Symptom	Likely Cause	FEIBI Solution
Gel Formation	Wrong viscosity	Immediate change to 0W oil
Slow Pressure Build	Oil pump cavitation	Pre-lube with FEIBI Primer
False Low Level	Oil contraction	Verify at operating temp
