Frequently asked questions

Is this the correct oil for every Caterpillar engine?

No. Newer engines with aftertreatment systems can require a different Cat oil category. Confirm the engine model, emissions tier and operation manual before ordering.

Does CI-4 replace the need to check viscosity?

No. Both the API category and SAE viscosity must match the equipment requirement and operating conditions.
