[Maintenance] "Oil" Is Important! Guidelines For Selecting Engine Oil For National VI Engi

In Order To Meet Strict Emission Requirements, China VI Engines Have Added New Technologies And Components. In Addition To Raising The Standards For Fuel And Urea, Stricter Requirements Have Also Been Put Forward For Engine Oil

National VI Engine Oil Performance Requirements

NO.1

Turbocharged Cylinder Direct Injection Technology Is Prone To Low-speed Premature Combustion, Requiring Lubricating Oil To Suppress The Accumulation Of Sludge And Carbon Deposits Around The Combustion Chamber And Fuel Injectors.

NO.2

Selective Catalytic Reduction Systems And Particle Traps Contain Rare And Precious Metals Such As Platinum, Gallium, And Palladium, Which Are Easily Oxidized And Damaged. Therefore, Lubricating Oil Must Have Low Sulfur And Ash Content, High Cleanliness, High Oxidation Resistance, And High Sedimentation Resistance.

Therefore, Low Performance Standard Engine Oil Is No Longer Sufficient For The Use Of National VI Engines. So, What Grade Of Engine Oil Should Be Chosen For National VI Engines?

Engine Oil Is A "base Oil" Extracted From Petroleum And Made By Adding Various Additives According To The Performance Requirements Of The Operating Environment, Which Plays A Role In Lubrication, Cleaning, Cooling, And Sealing. What Oil To Use Requires Two Indicators To Be Identified:

Oil Viscosity Grade

Oil Viscosity Is The Most Important Performance Indicator For Measuring The Fluidity Of Oil In Various States.

Oil Quality Grade Mark

API (American Petroleum Institute) Introduced The CJ-4 Engine Oil Standard In 2006 For The Development Of Diesel Engine Technology, And The CK-4 Engine Oil Standard In 2016. The CJ-4 Standard Replaces CI-4, CH-4, And CF-4, Mainly Designed For Heavy-duty Diesel Engines With Exhaust Gas Cooling Cycle (EGR) And Particulate Filter (DPF).

National VI Diesel Engines Should Be Used

APICJ-4, API CK-4 Or Higher Grade Engine Oil!

What Are The Hazards Of Using Substandard Engine Oil?

NO.1

The Deterioration Or Lack Of Engine Lubrication Function Leads To Early Wear And Shortened Service Life Inside The Engine.

NO.2

Causing Damage To The Post-processing System, DPF Is Clogged Due To High Oil Ash Content, Resulting In A Shortened Cleaning Range And Reduced Lifespan Of DPF Service.

The Post-processing Part Of National VI Vehicles Is Very Delicate, And Even A Slight Mistake Can Cause Post-processing Failures, Resulting In Vehicle Speed And Torque Limits, Seriously Affecting The Normal Use Of The Vehicle; The Use Of Substandard Engine Oil Causes A Sharp Increase In Ash Content In The DPF, Which Cannot Be Removed By The Regeneration System. When The Ash Accumulates To The Point Where Manual Cleaning Or DPF Replacement Is Required, The Cost Will Far Exceed The Money Saved By Purchasing Engine Oil!

So, For The Sake Of The "health" Of The Vehicle And The "health" Of The Wallet, It Is Urgent To Use Standard Engine Oil!
