True synthetics
True synthetics
(OP)
I have been searching the web to find the 'best'(price to oiliness value) synthetic oil for my cars. If the one exclusive oil site is to be believed there are no true 100% synthetics available.
Mobil 1's MSDS shows 4% polyolefins. What is the other 96%.
If this is a 'full synthetic' what is the make-up of a blend?
Any ideas?
Cheers

The wording "fully synthetic" may not be a "fully exact" definition after all.
Why not ask the opinion of the "big" makers who, no doubt, would be willing to answer queries of this sort.

RE: True synthetics
There are many types of full synthetics but for engine oils ther are typically two. 1) is PAO ( poly alpha olephin) which is man made from small gas type molecules which are chemically combined to form larger oil molecules. This gives a very uniform fluid with predictable qualities, but at a cost.
The second type are hydrotreated oils. These are severely purified and chemically altered mineral base stocks or waxes. These too have a uniform structure and predictable behaviour but are not as "PURE" as the PAO. However are much more cost effective and for most of us, offer the high level of protection we want for our bits of gear but without hitting the hip pocket as hard.
Then there are the semi synthetics which combine mineral base oils with some amount of synthetic base oil to improve the performance. These are about third on this list in terms of oxidation stability etc.
I hope this helps!

PIBs are commonly used in the adhesives and sealants industry. They are also used in the lube industry to prepare dispersant additives and VI improvers.
PIBs depolymerize and oxidize on heating, thus their use as base fluids is limited to metalworking and two-stroke lubricant formulations.

Mobil 1 - made by Mobil,most common?
Shell- not available in 5W30
BP- not available over the counter
Valvoline,Quakerstate, Castrol - about the same price as Mobil 1.Claimed by experts(Amsoil) not to be made by the brand on the bottle.
Havoline and Walmart - the lowest cost.
Which one/s are the best value for money?
Why is Havoline synthetic so much cheaper?
