Engine oil has viscosity, not elasticity. You can't stretch a liquid.
Engine oil viscosity:
Oil weight, or viscosity, refers to how thick or thin the oil is. The temperature requirements set for oil by the Society of Automotive Engineers (SAE) is 0 degrees F (low) and 210 degrees F (high).
Oils meeting the SAE's low temperature requirements have a "W" ("Winter") after the viscosity rating (example: 10W), and oils that meet the high ratings have no letter (example SAE 30). An oil is rated for viscosity by heating it to a specified temperature, and then allowing it to flow out of a specifically sized hole. Its viscosity rating is determined by the length of time it takes to flow out of the hole. If it flows quickly, it gets a low rating. If it flows slowly, it gets a high rating.

About the only scenario I can come up with is if the oil is contaminated with engine deposits, varnish,corrosion, etc. so that it becomes extremely viscous, like tar.
In that case, roll the deposit into a ball and bounce it off the floor.
If it bounces higher than your head, it is extremely elastic.
It is oftentimes difficult to be facetious in print, but I assure you, my tongue is firmly planted in my cheek.
Viscosity, i.e. resistance to flow, not elasticity, is how oils are graded.

I think engine oil elasticity is how thick the engine oil is.
