What is a Group V oil?

Group V base oils are classified as all other base oils, including silicone, phosphate ester, polyalkylene glycol (PAG), polyolester, biolubes, etc. These base oils are at times mixed with other base stocks to enhance the oil’s properties. An example would be a PAO-based compressor oil that is mixed with a polyolester.

Which oil is true synthetic?

A true synthetic oil is generally a Group IV oil combined with Group V additives in order to form a “true synthetic” oil. PAO oils have an even bigger advantage over Group II oils(the most common conventional oil) than Group III oils.

Is amsoil a Group 5 oil?

Today, most synthetics for motor oils are made using Group III base stocks. Mobil and Amsoil continue to use Group IV PAOs (Amsoil blends Ester with PAO) with Redline oils coming primarily from Group V Esters.

Is Mobil 1 a true synthetic?

Mobil 1™ Advanced Fuel Economy oils are fully synthetic motor oils engineered to deliver outstanding engine protection and fuel economy benefits.

Is Rotella a T6 Group 4?

Shell Rotella T6 Synthetic is a Group 3 Oil.

What is a Group 3 oil?

Group III base oils are greater than 90 percent saturates, less than 0.03 percent sulfur and have a viscosity index above 120. These oils are refined even more than Group II base oils and generally are severely hydrocracked (higher pressure and heat). This longer process is designed to achieve a purer base oil.

What is a Group 4 oil?

Group IV base oils are made from polyalphaolefins (PAO), which are chemically engineered synthesized base oils. PAOs offer excellent stability, molecular uniformity and improved performance.

What oil Group is AMSOIL?

Group IV PAO
AMSOIL’s Premium Lubricants are made up primarily of Group IV PAO base oils (with some Group V Esters).

What are the most common group V synthetics?

Esters are the most famous synthetics in Group V, which are 100% Synthetic chemical compounds consisting of a carbonyl adjacent to an ether linkage.

What is a group V oil?

Typical examples of Group V oils are esters, polyglycols and silicone. As with Group IV oils, Group V oils tend to offer performance advantages over Groups I – III.

What grade of oil is synthetic oil made from?

Some “synthetic” oil is made from Group III base stock, some from Group IV. Some from a blend of the two.
