I use Valvoline Engine Armour motor oil regularly, and I find it to be excellent - engine runs smooth, quiet at start up, and stays in-spec for a long time.

Use the 10w-30 in a Corolla, and 15w-40 in an older Commodore. Both are high quality products. Better than the Magnatec I used to use.

10w-30 is also the cheapest GF-5 economy spec motor oil around.

I just used this oil for my Honda civic 2008. I used various types of oil, usually very good brands but this one was different. Very smooth and clean without noise. Recommended!

Whilst I use full synthetic oil in my turbocharged car, this product is surprisingly good in my "****box" with a very high mileage where minimising oil consumption is more of a concern. Surprisingly this product has reduced consumption considerably through no reason I can gather. Valvetrain noise is quite low. Very affordably priced. I've even used it running my brushcutter when I ran out of two stroke oil, and it didn't foul the plug.

Have and still use Valvoline on everything from 4cyl to V8's even Merc & BMW, extreamly low on impurities, extreamly high on protection. Changed every 10,000klm and you can eat of your engine internals. So if you want to protect your engine, do yourself a favour and get Valvoline. Simply the best oil ever.

Used engine armour in my ford falcons for years and its protected my engines very well. Change my oil every 6 months or about 7500 km's and Im happy with how engine armour keeps my engines clean and running quiet and smooth. I like the 10w40 and the 15w40 grades and the 4.0 litre falcon loves them both.
good value for money and good engine protection
nothing

I use Valvoline Engine Armor in my AU XR8, have done for over 4 years oil always is as clean when its time to change as when ask first put it in, no engine noises or wear and tear in my motor parts are well lubricated never had a trouble with this oil

nothing at all

Quality and good price product that enables good engine performance and lowers fuel consumption. Easy starting in hot and cold. Will be using it in other vehicles as well.
