Grade finder

Find the right grade in two questions.

Tell us what you are running and how it is worked. We will point you at the grade that fits — and explain why, so you can check it against your handbook.

Step 1 of 2

What are you running?

Pick the closest match. If nothing fits, ask us directly

This is guidance, not a specification

The finder narrows the range down to the likely grade. It cannot see your machine’s handbook, its service history or its operating temperature. Confirm against the builder’s recommendation before you fill, and talk to us if the two disagree — that conversation is free and it is usually interesting.

Rather just ask a person?

Send us your fleet list, machine schedule or a photo of the handbook page. Our technical team will come back with grades, pack sizes and an indicative price.
