SwRI offers the Volkswagen T4 Evaluation using the apparatus pictured here.

Southwest Research Institute (SwRI) offers the Volkswagen T4 Evaluation (VW PV 1449), which evaluates a crankcase lubricant's performance in combating:

  • Viscosity increase

  • Total base number depletion

  • Piston deposits

Volkswagen Specifications

The Volkswagen T4 procedure is for Volkswagen factory-fill or service engine oil in spark-ignition engines with extended oil-change intervals (502, 503, 504, 507).


Field Service Simulated

The Volkswagen T4 procedure simulates passenger vehicles driven at high-speed, high-temperature conditions at full and part loads, along with periods of prolonged idle.


Volkswagen T4 Fixture

The fixture is an engine dynamometer test stand with a Volkswagen 2.0L four-cylinder, inline gasoline engine installed.


VW PV 1449 Parameters

The procedure is conducted for 248 hours and in two phases:

 

Properties Limits
Phase 1
(0–192 Test Hours)		 Phase 1
(192–248Test Hours)
PNK Stage 1 2 3
Time, min 120 72 48 72
Engine Speed, rpm 4,300 4,300 Idle 4,300
Engine Torque, N-m Max 75 – 75
Engine Oil Temperature, °C 133 130 40 130
Coolant Temperature, °C 100 100 30 100

 

Volkswagen Parts Evaluated

  • Piston rings are evaluated for sticking

  • Pistons are evaluated for cleanliness

  • Cylinders, cam lobes, cam followers and seals containing elastomer materials are evaluated visually

Used Lubricant Analysis

During the 248-hour oil drain, the following are evaluated:

  • Kinematic viscosity

  • Total base number

  • Iron content

  • Chrome content

  • Copper content

Pass / Fail Criteria

Candidate oils are judged against test laboratory's adjusted performance on reference oil 76409. At 248 hours, determining criteria include:

  • Absolute viscosity

  • Viscosity increase

  • TBN level

  • TBN depletion

  • Piston cleanliness

 

ACEA 2004 limits are being defined.
