We’ve Got You Covered

Marine oils are developed specifically to meet the challenge and rigours of the marine environment. Whether you’re maintaining a fishing vessel for the open seas or a motorboat whizzing along river bends, you’ll find the right lubricant for the job in our selection of products. These include variants for both premix and direct injection engines in both outboard motors and most 2-stroke engines. This means that we can provide industry-leading corrosion protection and outstanding lubricity for most marine engine types.

To find out the best oil for your boat's engine (2-stroke or 4-stroke, inboard or outboard), let the staff at Supercheap Auto help you out with information! We have a number of outlets available throughout Australia, you can visit or even just give us a call to chat with our knowledgeable staff. Alternatively, you can browse and buy marine oils for sale online with our comprehensive collection.
