Gulf Western Oil’s latest offering, the all-new Top Dog Indestructible 15W-40 CK-4, is a real game changer for heavy-duty diesel engine lubrication.

This uncompromising next-generation heavy-duty diesel engine oil contains ground-breaking indestructible additive technology specifically designed to protect high-powered, turbo-charged heavy-duty diesel engines.


The unique formulation contains performance-enhancing and superior wear protection technology that far exceeds the requirements of the latest API CK-4 lubricant specification.

Top Dog Indestructible 15W-40 CK-4 meets the requirements of most modern engine manufacturers’ specifications, and being backwards compatible with API CJ-4, CI-4 and CH-4 means it will also suit most older heavy-duty diesel engines. Having a low SAPS level, it is also suitable for diesel engines fitted with EGR, DPF and SCR/AdBlue.

This ground-breaking new product has seen years of research and development both in Australia and overseas that has culminated into measurable and repeatable real-world results, offering heavy-duty diesel engine operators increased service intervals, dramatically decreased engine wear, increased fuel efficiency through reduced friction, increased shear stability resulting in decreased oil consumption, and better dispersancy compared with conventional API CK-4 and CJ-4 specifications, resulting in cleaner engines that offer increased service life.

Most importantly, Top Dog Indestructible 15W-40 CK-4 offers improved reliability and less downtime, increasing profitability in the long-term for the end user.

As testament, long-time Gulf Western Oil customers such as Blenners Transport, with its fleet of 160 trucks and 220 refrigerated trailers, have been using the new oil with spectacular results. Using a careful approach with additional filtration and constant oil sampling, the company now sees oil drain intervals as high as 60,000km.

With results like this deemed near impossible not so long ago, it really is an exciting time for Gulf Western Oil and its customers.


Gulf Western Oil, Australia’s largest 100 per cent locally owned lubricants manufacturer, is no stranger to the earthmoving industry, delivering solid and reliable products for 30 years now.

Back in 2013, managing directors Ben and Andrew Vicary took this already impressive service to a whole new level, starting with a clean slate and building a brand new state-of-the-art manufacturing plant. Fully computerised and stainless hardware equipped, the level of sophistication, technology, storage capability and the team's global experience housed within this huge facility is a sight to behold for anyone lucky enough to secure a factory tour.

All Gulf Western products are designed and manufactured for Australian and Pacific Rim conditions; and suitable to a wide array of applications: earthmoving, transport, mining, industrial, construction, marine, agriculture, motorsport, your everyday vehicle and much more.

Extensive product research and development combines Gulf Westerns high-tech laboratories and Australia’s harsh environment in the ultimate torture test over many millions of km’s on land, sea and even the race track, with drag racing champions like Victor Bray and Rachelle Splatt; the "Queen of Speed".

All this is backed by API licensed and OEM approved products manufactured under an ISO 9001:2015 quality assurance management system certification.
