Does single grade oil have a viscosity modifier?

A single grade oil does not contain viscosity modifier or polymeric viscosity index improver. The SAE classification (SAE J300) has proven 11 viscosity grades. Six of them are recognized as winter grades with a “W” designation. The eleven viscosity grades are: 60, 50, 40, 30, 20, 25W. 20W, 15W, 10W, 5W, and 0W.

How to read oil viscosity (SAE 10W-30)?

Here is another interpretation of how to read oil viscosity (SAE 10W-30) SAE = Society of Automotive Engineers 10W = the viscosity of the oil when measured at 0 degrees Fahrenheit (the “W” means winter grade) 30 = the viscosity of the oil when measured at 212 degrees Fahrenheit

How is recycled motor oil made and refined?

Recycled motor oil is re-refined using a multi-step refining procedure that is very similar to that which is used to refine crude oil. The resulting base stock is as good or better than comparable virgin oil, and meets the same API and OEM performance requirements when it is reformulated with the proper additives.

Can I use multi-viscosity oil for a worn out engine?

If you have a worn out engine and you have been running 30 weight oil or 40 weight oil, then a multi-viscosity oil will not be reliably thick enough to grease the worn out parts of the engine that are wearing down. The best course of action is to switch to a heavier straight weight oil in order to keep the oil thick enough to fill the gaps.
