Great all-purpose oil.
20 March 2014boingk

originally posted on supercheapauto.com.au

Works well in most modern vehicles including a 2008 turbo-diesel Toyota Hilux ute and 2000 Honda VTR1000F motorcycle. Great stuff, excellent pressure under high load and temp and gives very smooth shifts in the motorcycle.

Great oil for my DMAX and Wet Clutch Motorcycles .

Purchased from number one ( SUPERCHEAP AUTO ) at a great price , use it to service my 2016 ISUZU DMAX 4X4 , and use it to service my motorcycles with wet clutches . DMAX runs great , motorcycles run great with smooth gear changes , and no clutch slip what so ever . Australian product from number one seller.

Multi-use diesel engine oil
18 December 2019

Gulf Western Oil is generally on the lower end of the price spectrum and so they sort of miss out on the high quality image that the other Aussie brands have. But after using their products for a few years in every machine I own, I can safely say the quality is right. I use Top Dog XDO 15W-40 as a multi-use oil for my diesel Landcruiser and petrol lawnmowers. Really the only (minor) disadvantage with XDO 15W-40 is the pour point of -21C might be inadequate for cold climates, in which case there are better options. Cleaning performance is good, the API ratings aren't the latest but that's being addressed in newer products. I've got to compliment GWO on their professional MSDS and datasheet files that help make comparisons easier. I've personally had a good experience ...Β MoreGulf Western Oil is generally on the lower end of the price spectrum and so they sort of miss out on the high quality image that the other Aussie brands have.
