Seems like Amsoil has released a new oil similar in specs and price to TSO 0w-30. Any try it yet or have a comment? Here's the specs.
The tests shows it does well, but compared to TSO, pretty close. Also note the significant difference in numbers between the m1 EP, and havoline samples
SSO

TSO

 

pensoil platnum is only 19.99 for 5 qts at wallmart !!!!!!!!! you cant beat it!

 

I'll stick with mobil 1 0-w40

 

Good stuff, its what i've been running for a while now.

 

Blenders are changing and introducing formualtions too fast to keep up with. I'm sure this will perform well, like most AMSOIL oils. If anyone gets a UOA, please post the results in the oil analysis sticky so we can check it out.

I'm interested in a UOA as well, but the TSO is slightly better in wear (0.360) than the new SSO (0.406) so why change? Unless the new SSO is cheaper in price.

I'm currently using TSO 0w-30 and happy with it.

 

That was for the old TSO though, not sure how the new one would test, and the tests weren't performed at the same time, and if you cross check between same oil brands in both tests, there is some variation in the numbers so its hard to say whether one is better than the other or not.

 

yeah... i just run oil... mainly because i plan on getting it built eventually anyways.

 

Yes, realized after I replied that tests results are two years apart.
And noticed the Pennzoil P is slightly higher in wear as compared to same test back in 2005, which follows suit with slightly higher number on SSO compared to TSO 2 years ago.
However, Castrol 0w-30 only varied by 0.001. It is interesting to see what happened to Mobil EP changing for the worse and Havoline improving. Formulation changes my guess.

I'd like to see Amsoil's 5w-40 (AFL) Euro Oil results and UOA. Was and still considering trying AFL.

 

I don't put much value on four ball wear tests. Only slightly more applicable than the old Timken test, but neither are considered indicative of overall engine oil performance. It's just another means to identify the presence of EP additives. Amsoil makes a great product, but their marketing drives me nuts sometimes.

You guys should look into Eneos 0-50.

here some more info on it http://www.eneos.us/web/

In my opinion this is by far the best oil out there. The Z loves it.

 

0w-50? Are you kidding me?

 

No not kidding you, totaly serious.

 

what is your justification for switching to a 50 weight oil on a car requiring a 30 weight unless its TT or a track only car?

 

The Z loves it? How do you figure? Does it just sound better or do you figure the Z loves it because it hasn't blown up yet? I could put the cheapest straight 30 weight G2 oil in your Z and it wouldn't blow up either, and the "sound" or "feel" of your engine with an oil is totally subjective. So, I'm curious how you know your Z "loves" it.

If you have a UOA with this oil, then by all means please post it in the oil analysis sticky and let us know what you use your Z for.

Do you race the car, or are you FI? I wonder why you bought some expensive oil with such a huge VI. The VQ can use a 40 weight as per the owners manual, but this 50 weight is pretty thick. 17.9 cSt @ 100deg C to be exact. I wonder how this might affect timing on the hydraulic operation of the CVTC system, not to mention the fact that an oil with that high of a VI will be VERY susceptible to shearing. Even if high-end diesters are used (which have a decent VI by themselves) there will be a high amount of VII's to acheieve this multi-grade spread. Since Eneos uses (as best as I can figure) PAO4 and PAO8 compounds as the base stock, this frees up the need for a lot of antioxidants in the add pack that the esters would require, but a heavier need for shear-prone VII's. So, I would question the stability and most of all -the NEED- for such an oil in a daily driver. Even if you track the car a lot, your priority would be for a high HTHS score in as thin an oil as possible to maximize flow across the bearings. This oil's HTHS of 4.6 can be matched in some thinner 40 weight oils. In short, I think you wasted a lot of money on a boutique oil that is probably not best suited for your needs.
