Diesel and Petrol Engine Oils |
| Engine
oil performs several crucial tasks for both diesel and petrol engines
to maintain optimum performance. The following diesel / petrol
schedules have been derived. Scheduled oil analysis is the best way to
maintain the balance between the premature and reactive maintenance. |
Testing Level
|
| Level 1 |
Used
when there is no apparent concern due to contamination or wear. A basic
analysis that serves as a useful tool to obtain an overall view of the
compartment.
|
Level 2
|
When issues arise with the performance of the compartment and the oil.
|
Level 3
|
This
level of testing gives you key performance indicators of the oil and
the compartment. Best suited for warranty purposes. This level of
testing will comply above and beyond any OEM's requirements.
