VETUS Marine diesel synthetic engine oil SAE 10W-40, 4 litre

Four litre pack of SAE 10W-40 synthetic marine diesel engine oil — the usual size for a service oil change on a single engine. Same oil as the one litre VMD101 bottle.

30-day no-fuss returns. If you opened the box and the part doesn't fit, send it back unused within 30 days for a full refund. We'll cover return freight on our error; you'll cover it if the part was correct as ordered.

12-month warranty. Manufacturing defects covered for 12 months from purchase date. Wear-and-tear (impellers degrade with use — that's their job) is not covered, but reach out if something fails early and we'll work it out with the manufacturer.

Australian Consumer Law applies in addition to the warranty above.
