Why this page matters
Make OBT2 feel like a full oil service lane from day one.
OBT2 should feel technical, practical, and serious inside CodeSafe. The structure should support learners who need more than surface-level burner questions.
Combustion and service depth
Train with questions built around burner adjustment logic, combustion quality, controls, wiring, and the service decisions that show up in real oil work.
Mock exam pressure
Use structured mocks and longer practice runs to build timing, accuracy, and confidence before test day instead of waiting to feel pressure in the real exam room.
Technical review that teaches
Every explanation is meant to connect the answer back to the burner condition, control function, or code rule being tested so the knowledge actually sticks.
Topic coverage
Built around the systems and service calls OBT2 techs actually deal with.
The bank should feel organized by real oil burner pressure areas, from draft and combustion to controls, burner adjustments, and service troubleshooting.
Practice modes
Three ways to train.
Easy Mode
Build confidence with burner components, combustion basics, and control sequence fundamentals.
Medium Mode
Work through deeper service decisions, adjustment logic, and troubleshooting scenarios.
Mock Exam
Simulate a full OBT2 exam session with realistic pacing and review afterward.
