Transcript: Technology matters
The Voice-over begins over a grey screen background.
‘The unique technology of Shell Helix Ultra motor oilcleanses and protects engines for maximum performance.To see the technology in action, let's take a journey inside the engine.’
The animation begins with a bottle of 4 litre Shell Helix oil being poured into an engine. The voice-over continues;
‘Once the oil is poured into the filler cap, it flows down to the sump at the bottom of the engine,’
We see an animated journey of the oil travelling down to the engine and we see the oil as it collects in the bottom of the engine. We see how the oil is then pumped through the oil ways up through to the filter. The voice-over says;
‘where it collects and is then drawn through the oil ways up to the oil pump and forced through the filter.We've chosen a four cylinder petrol engine as it's one of the most successful and widely used engine designs today.The filter removes any large particles from the oil, which can cause wear and blockages.’
We see the journey the oilmakes inside of the moving engine parts and how it lubricates each of these parts. The voiceover continues;
‘From here, the oil is fed into the crank shaft to lubricate the bearings,and is sprayed onto the underside of the piston and cylinder walls to provide essential cooling and protection.The oil then travels up through the oil ways to the top of the engine where it lubricates the camshaft to ensure smooth contact with the followers, which move the valves.’
We then pan out to seean animation of the inside of a fully working engine, which highlights how the oil is moving around the engine. We then cut to a grey screen with the words’Shell Helix Ultra, Active Cleansing Technology’ in black. We cut back to the animation of the engine and zoom in to the oil itself. The voice-over says;
When using a normal mineral oil, engine sludge can build up from small particles of degraded oil and combustion by-products, sticking together and accumulating on engine surfaces.
We see groups of black particles in the oil gathering together to form bigger particles and this builds up till there are quite a few groups of black particles in the oil. The voice-over continues;
‘This dirt can lead to increased engine vibration and wear and a decrease in efficiency and performance.As the engine gets dirtier, the oil degrades faster, altering the oil viscosity and reducing the protection of vital engine parts.’
We then pan back out to the animation of the engine and we see the movement of the oil as the crankshaft of the engine is in moving. We then cut to a grey screen with the words ‘Shell Helix Ultra, cleans 5 times better than a normal mineral oil.’ We then cut back to the animation of the engine and zoom back into the oil. We see groups of black particles in the oil as yellow particles move across the screen pushing moving all the black particles along with it. The voice-over continues;
‘Shell Helix Ultra's unique formulation contains active cleansing agents performing two vital tasks.The first ensures that small dirt particles are surrounded by the oil and held in suspension.This prevents them sticking together and forming larger accumulations of harmful dirt and sludge.The second task cleanses the engine surfaces where dirt may have built up.The active cleansing agents break down dirt deposits and hold these in suspension until the next oil change when they can be safely removed with the oil.’
We pan out of the oil and back to the animation of the crankshaft.The voice-over says;
An engine kept clean with Shell Helix Ultra will provide maximum performance, protection, and efficiency.In tests, Shell Helix Ultra has been shown to reduce sludge build up five times more effectively than normal mineral oil.
We then zoom into the piston rings; we see the piston rings moving up and down as the voice-over continues;
‘The piston rings play a very important role, stopping combustion gases entering the bottom half of the engine where they contaminate the oil.With normal mineral oil, dirt accumulates in the piston ring grooves, creating an uneven surface and forming gaps that allow gases to escape downwards;these gases end up in the sump, breaking down the oil, preventing it from protecting the engine effectively.
We pan into the piston ring groves and see how the oil lubricates the grooves on the pistons.
‘Shell Helix Ultra's active cleansing agents work to keep the piston ring grooves free from dirt.The clean grooves allow the rings to make a tight seal, preventing gases from escaping downwards,and thus ensuring the oil effectively protects the engine right up until the next oil change.’
We then cut to a grey screen with the words ’Shell Helix Ultra, Superior Shear Stability’ in black. We then pan back into the animation of the moving crankshaft and zoom in to the oil that is lubricating the crankshaft. We see the yellow particles in the oil as it flows round the crankshaft.
‘In many parts of the engine, there are points of very high shear.One of these is the crankshaft bearings.The forces here are so great that the molecules responsible for maintaining viscosity in normal mineral oilscan literally break apart, leading to a loss in viscosity.This means the oil's ability to provide effective engine protection is much reduced.
We cut back to a grey screen with the words ’Shell Helix Ultra, 3 times better shear stability’ in black. And then switch back to the animation of the oil lubricating the crankshaft and we see the yellow particles going round the oil as the oil lubricates the crankshaft.
The molecules in Shell Helix Ultra are designed to withstand the extreme shear forces,enabling the oil to maintain the correct viscosity.In tests, Shell Helix Ultra provided superior engine protection.’
We cut back to a grey screen with the words ‘Shell Helix Ultra Excellent Oxidation Stability. We then cut to a shot of a close up of the oil. We see red particles, yellow particles, green particles and black particles flowing in the oil. The voice-over continues;
Free radical particles formed from acids and by-products of engine combustion can harm oil molecules.In normal mineral oils, they oxidise the oil, degrading and thickening it over time.This leads to a dirty engine and reduced ability of the oil to protect.
We cut back to a grey screen with the words ‘Shell Helix Ultra, 2 times better oxidation resistance’. We then cut to a shot of a close up of the oil. We see red particles, yellow particles, green particles and black particles flowing in the oil. The voice-over continues;
The additional antioxidants in Shell Helix Ultra's formulation neutralise more of the free-radicals,slowing down the oxidation process.This means the engine oil can protect the engine parts and ensure it operates at its best.
We cut back to a grey screen with the words ‘Shell Helix Ultra, cleans and protects for maximum performance’, followed by ‘ Cleans 5 times better than a normal mineral oil’ followed by ‘3 times shear stability’ and then ‘2 times better oxidation resistance’. The voice-over continues ;
‘Shell Helix Ultra technology provides you with five times better cleaning,three times better shear stability,and two times better oxidation resistance than a normal mineral oil.’
The words disappear and a dark blue revolving bottle of Shell Helix appears, the voice-over says;
‘If you want maximum performance from your motor oil, make sure you choose Shell Helix Ultra.’
