My daughter drives a 1994 C180 Mercedes, it's done just shy of 300,000km and burns about a litre of oil every 10,000km or so we usually run Penrite 10-50W. The young fella at Supercheap recommended it to her for an oil change, having never used it before I figured why not, at a mere 1500km it had turned dark brown and looked like it had been in there for ever and managed to burn away two litres!!!! Penrite back in and it stays nice a golden to at least 7000km and doesn't burn away anything like this does.

Gulf Western uses deceptive packaging. Beware, this is not a full synthetic oil although the packaging would have you believe it is. Why it is not labelled as semi-synthetic like all other products of this nature in the industry is an interesting question. Will not buy again.

Just like the tittle says, this is really deceiving wording, as it is NOT FULL SYNTHETIC.It SHOULD say synthetic BLEND, which it says NOWHERE on the bottle. Only when you go to the website it states it is a synthetic blend, which is FAR inferior to FULL synthetic, so no wonder they can sell it so cheap (on special)I thought something was up when the Syn-X 6000 says full synthetic yet this only says synthetic, but again NO WHERE on the bottle does it state it is a blend, which is extremely decieving. Every other blend is marketed as such or semi-synthetic. This is the first time I've come across this decieving practice so I'll be steering clear of Gulf Western, which is unfortanate as I was buying it to support an Aussie company, but will not support one that is ... MoreJust like the tittle says, this is really deceiving wording, as it is NOT FULL SYNTHETIC.It SHOULD say synthetic BLEND, which it says NOWHERE on the bottle.

Old Gulf Western is always a winner in the shed, use for all services. Also another great must have item that is often in sale! Performance wise is great, never let down.
Use this oil for my motorcycle - wet clutch as it is equiverlant to JASO MA classification ( I spoke with their Chemist / Engineer). A lot cheaper than other branded "motocycle" oil.
I use this on a variety of motorcycles with wet clutches. It is recommended for motorcycles by Gulf Western and has a JASO MA rating. Much cheaper than specific motorcycle oils, and suits a variety of cars, also, with SN/CF.
Provide great protection during cold engine start and during hot running. It is light enough when is cold and thick enough when is hot. Therefore; reduces engine wear and provides great protection.
Good product and much cheaper than other alternatives you stock - for the same benefit. Was a bit annoyed however that I asked for a budget alternative and was recommended to the most expensive, then a mid range (both out of stock), and then I was pointed to this oil - half the price of the original suggestion.....
First time using this product. Was the best price on shelf. Engine is running fine with no noises. See what happens at next service.
I was pleased when my independent car mechanic told me he uses this oil for all the services he does. He has visited the Gulf Western factory and says it is amazing. I'm using it in my 1300cc motorcycle and it is performing very well in hot conditions. I prefer it over more expensive imported oils.
