Title: AeroShell Oil W15W50 Cold Flow Video
Duration: 1:53 minutes
Description:
AeroShell Oil W 15W-50 flows more quickly than competitor oils, even when cold, to protect important parts of your aero piston engine from wear. Watch as 4 piston engine oils are tested for cold flow performance after being stored at -40 degrees Fahrenheit (-40 degrees Celsius).

Oil has a crucial role to play in keeping costs down by protecting your engine from wear. Most wear occurs on startup as pressure builds and the oil flows to where it is needed. That means the speed at which your oil flows is important, especially on a cold day.

[Dialogue: Narrator]
If your oil fails to flow to where you need it, your engine components may be grinding against each other, metal on metal. One particular area of concern is the camshaft and valve lifters.

Setup of 4 tubes of oil held by metal structure, pointing diagonally downwards with metal tray under the tubes. A sped-up timer starts running from 0 minutes. The oil in the tubes are flowing out at different speeds. The right most tube with black coloured oil flows out the quickest, followed by the 2nd from right, an amber colored oil. At the 30 second mark, the oil in the left two tubes have yet to flow out from the tube onto the metal tray.
[Dialogue: Narrator]
If worn components need to be replaced, your overhaul will be expensive.
Let’s see how these oils flow when chilled to minus 40 degrees Fahrenheit. Two of the samples are flowing immediately with a good consistency. Meanwhile, the other oils have barely moved. Imagine these oils were in your sump on a cold day. That’s a lot of time for damaging metal-on-metal wear. The oils on the left are formulated with a mineral base oil and have a 20W low-temperature viscosity, whereas the other oils are formulated with a semi-synthetic base oil and have a 15W low-temperature viscosity. The samples on the right are new and used AeroShell Oil W 15W-50. The others are the next most popular multigrade oils.

Applications
AeroShell Oil W 15W-50 is intended for use in certified four-stroke (four-cycle) aircraft piston engines. AeroShell Oil W 15W-50 is superior to single grade oils in almost every application. It offers easier starting, better lubrication after start-up, reduced wear, reduced corrosion and rusting, and improved cleanliness, with oil pressures and temperatures equal to that of single grade SAE 50 oils at fully warmed up conditions.
The anti-corrosion additive system is designed to prevent rust or corrosion in all types of aircraft piston engines. In comparative testing of camshaft rusting under high humidity conditions, AeroShell Oil W 15W-50 was almost entirely rust free while camshafts conditioned on other oils showed heavy rusting on some cam lobes and bearing surfaces.
These results indicate that AeroShell Oil W 15W-50 can provide maximum anticorrosion protection for aircraft piston engines, when combined with proper maintenance practices and proper operating conditions.
Because of the improved flow characteristics of AeroShell Oil W 15W-50, operators may observe slightly lower oil temperatures in some aircraft. On larger aircraft, the oil cooler flap will normally compensate for this change. However, in small aircraft, oil temperature could be reduced slightly. Operators should always check the oil temperature to ensure that they are in the range specified by the manufacturer. Most manufacturers recommend cruising oil temperatures between 82 to 93°C (180 to 200°F). Oil temperatures significantly below this range can result in excessive water and fuel contamination in the crankcase.
