Gulf Western engine oil is the best for price (always buy when it's on special)! I am a mechanic and have been using Gulf Western oil for many years. Always super happy with the quality of Gulf western products. Cars run really smooth! Really wanna know what secret ingredients are in Gulf Western oils:)

Ive used the expensive brands , ive tried just about every oil on the market here in australia and the USA and this particular oil is great.Many people use a thicker oil in the LS engines but i have found that this 5w30 is the best for performance and fuel efficency.

The GW 5W-30 I use in a Subaru Forester and it seems to work well and for a full syn is available at a good price. I would call it value for money

I’ve been using Castrol Edge in my Holden Captiva & Honda City for years now. I decided to try the GW engine oil to see how it compares. To be honest it’s only been a few weeks, but it seems fine & i’d use it again. Separate to this review, the GW auto-trans fluid performs well also. Give their products a go.
Great Aussie engine oil, competitive pricing and performance. I have used this oil for years and never disappoints keeping my car running smooth and protected.
Gulf Western oils are of high standard and Gulf western lubricants have been around for many years servicing Transport industry , Mining , Agriculture and Industrial applications before becoming more visible to the retail sector . I have sold their oils for years whilst in the spare parts industry for Truck , Trawler and Automotive users.
I have always been a Castrol man, but after a very long thought process I tried this whilst on special. I even got an oil analysis done at the next service, came back good. So bottom line is it works as advertised and it keeps a bit of my cash in Oz so win win.
So I thought id give this a try, instead of the expensive stuff i usually run. And so far it hasn't dissapointed. My turbo diesel runs quiet, theres no smoke on startup, ill know how it goes after i drain it in 5000km, but so far im happy, especially for the price, considering the stuff i normally run is double!! so i will likely keep using this stuff.
I switched to Gulf Western about a year ago as it was the best value fully synthetic oil I could find, I have found it to be a reliable product and haven't had any issues with it. Compared to the more branded oils, this does the same job without the extra marketing that comes with the bigger names. Happy to recommend this product.
good service normal but this covid service very sad. Took 45 minutes to get one only 5lt bottle of oil.If thats service im not going back. Lucky it wasa nice sunny morning, and I had a free day to play you games. I went to coles next, walk straight in , get what i needed, walked out , took 5 min. Whats the differents. .
