Synthetic oils

[bigdogxx]

Interesting article i found over at the coloradofans board, maybe i should think about switching from m-1 if what im paying for which i thought was a full synthetic is really a over priced grp 3 oil.

 

 

 

did a search and didn't see this brought up. If it was excuse my ignorance.

 

but it has come to my attention that Mobil 1 has gone to group III oils (might have happened awhile ago, but I was just informed.)

 

another forum I'm on brought up this post on BITOG

quoted from above website!

 

Shortly after Mobil lost their lawsuit, most oil companies started reformulating their synthetic oils to use Group III base stocks instead of PAOs or diester stocks as their primary component. Most of the "synthetic oil" you can buy today is actually mostly made of this highly-distilled and purified dino-juice called Group III oil. Group III base oils cost about half as much as the synthetics. By using a blend of mostly Group III oils and a smaller amount of "true" synthetics, the oil companies can produce a product that has nearly the same properties as the "true" synthetics, and nearly the same cost as the Group III oil. The much more expensive traditional synthetics are now available in their pure forms only in more expensive and harder to obtain oils. To the best of my knowledge, Delvac-1, AMSOil, Redline, and Motul 5100 are the only oils made from pure traditional synthetics

 

but what I read here, Amsoil also changed to group III

good info. on oil groups here.

run down:

 

 

Group I = mineral oil with the least amount of processing / refining

Group II = mineral oil with more processing / refining

Group III = mineral oil processed / refined to have viscosity index comparable to group IV

Group IV = polyalphaolefins made from natural gas

Group V = other

 

In the US, group III, IV, and V can be marketed as "synthetic". In some other places, group III is not marketed as "synthetic".

 

Typical $1.50 conventional motor oil is group I and/or II. The viscosity index is typically only sufficient to provide SAE grades of 5W-20, 5W-30, 10W-30, 10W-40 (marginally), 15W-40, or 20W-50, or single grades. "Wider" SAE grades would require too much viscosity index improver, which has undesirable characteristics when too much is used (e.g. the oil easily shears out of grade after it is used for a short while -- 10W-40 conventional oil has a reputation of doing that).

 

Group III, IV, and V based oils can provide "wider" SAE grades like 0W-30, 0W-40, 5W-40, and even 5W-50. "Narrower" SAE grades like 10W-30 may require little or no viscosity index improver.

 

Of course, base stock is not the sold determinant for whether the oil is suitable for use in a given engine. Many engines have specific oil requirements -- a "synthetic" oil that does not meet the requirements may not be suitable at all. E.g. recent VW gasoline engines require VW 502.00 rated oil. In the US, only "synthetic" oils meet that, but not all "synthetic" oils meet that.

 

For whatever reason, people in the US seem to place great importance on whether the oil is "synthetic", rather than actually reading the car manual for the required oil spec.

 

 

take the info. as you like, I'm not bashing on anything, just trying to inform people, me being a mobil 1 user since the truck was new, will most likely be switching to Rotella just to save myself a few bucks (I use Rotella T in my wife's diesel Jetta), It's a group III oil, but not for the group IV price!

Interesting article i found over at the coloradofans board, maybe i should think about switching from m-1 if what im paying for which i thought was a full synthetic is really a over priced grp 3 oil.

 

 

It's your money do what you like. I have seen many engine oil analysis that show the best wear numbers next to GC. This is more propaganda for the haters of M1. I think it is envy but hey thats my opinion.

GC? And how is this propaganda, you see it here all the time most people here think when there bying m-1 they are buying a full synthetic like myself, and looks like m-1 made this switch without saying a word and ofcourse sticking with a full syn. price.

Castrol is the outfit using GrpIII and calling it a full synthetic. M1 has always been PAO. M1 sued Castrol.

 

Maybe some of their new 5000 mile oil is 'only' Grp III.

GC- German Castrol

 

I'm not going to bite on this crap. Maybe you ought to do some reading on BITOG.

These are facts, there are only a few full PAO synthetics out there. Top line M1 and Amsoil are full PAO, the 7500 Ams and 5k M1 are not.

I use Valvoline 5W-30 and PureOne filters. Blackstone labs says my engine is awesome at 100k miles.

AMSOIL's group III oils are their XL line and their PCO 15w-40 synthetic blend oil. The rest are PAO.
