Seriously though, would you put this in ANY car? Tesco seem to think so given how much of it they have in stock.

Got some 20w-50 at £4 for 5 litres - "Formula 1" for my Landy (old engine - new one uses good stuff 
)
After 2 weekends off-roading I was getting lower oil pressure readings than with the manky old 10w-40 semi-synth I replaced it with! Not very good for a thicker oil.
Good stuff will have APi/ACEA ratings (usually SJ, A3/B3). Cheap stuff never has these - and there's the clue!

if it's going in a scoob don't worry. It's designed for mass produced small family cars like an impreza. The people on here think an impreza turbo is some sort of ferrari. Not a £20,000 4 dr family car.
It will be fine.

I wouldn't use it. Use a decent oil and you'll get better cold starts, smoother running, less wear on your engine, better fuel economy and it will last much longer - false economy to buy cheap stuff.
I doubt there is any manufacturer out there that recommends anything less than 15w 40.
Might be okay for a petrol lawnmower, but not a car.

That's cheaper than a decent basestock so god knows what it's made up of
You're welcome but I wouldn't touch it with your bargepole!

It's pretty simple really, a vast number of people really don't fully understand what an oil does. It performs many important functions within the engine and here are the main ones:
LUBRICATE
Motor oil must lubricate engine components so that they will easily pass by one another without a significant loss of power due to friction. At start-up, this is especially true. As an engine sits, oil tends to run down into the oil sump. Therefore, when the engine is started, the oil must be quickly pumped throughout the engine to provide sufficient cranking speed for the engine to turn over.
Once the engine is running, engine oil must create a film between moving parts to make them "slippery" which increases power, performance and efficiency. Each different type of engine requires a certain viscosity range in order that the oil will provide an adequate film between moving parts while still flowing quickly and easily enough throughout the engine.
Some people mistakenly believe that if an SAE 30 oil provides good protection, an SAE 50 oil must provide greater protection. That's not necessarily true. If your vehicle was not designed to take an SAE 50 oil, using one may not cause more engine wear, but it will likely cause an increase in engine temperatures. This can be just as bad for the longevity of your engine as engine wear.
PROTECT
The film that an engine oil provides between metal surfaces does more than just lubricate. By keeping engine components from coming in contact with each other, a motor oil also provides protection against wear. However, there is another way in which an oil protects.
Engine oil must protect against corrosion of engine components. Oxidation of the oil and contamination via condensation and combustion by-products all cause acids within an engine oil. If these acids are allowed to come into contact with engine components, corrosion occurs and premature component failure is the result. Engine oils are designed to combat these acids.
CLEAN
If an engine does not remain clean, it does not remain efficient. Deposits within an engine gum up the works and reduce fuel efficiency while robbing your engine of performance. In addition, contaminants within an oil that are left "unguarded" can cause incalculable wear within an engine.
Any particle larger than 5 to 20 microns in size (depending upon the vehicle) will seriously damage an engine if not removed or contained. To give you an idea of how small this is, a human hair is 100 microns thick. Although filtration plays a big role in this area, the oil also has to play it's part by keeping deposits from forming within the engine and by holding contaminants in suspension until they can be removed by the oil filter.
COOL
Engine oil is responsible for a large percentage of the cooling that takes place within your engine. Your radiator is only responsible for cooling the upper portion of your engine. The rest, crankshaft, camshaft, timing gears, pistons, main and connecting rod bearings and many other critical engine components are cooled mainly by the motor oil within your engine.
Heat is generated within an engine from both the combustion process and the friction caused by the motion of engine components. As oil passes through the system it is directed onto these hot surfaces in order to carry the heat away to the oil sump. From here the heat is dissipated to the air surrounding the sump.
