What Amsoil is closest to M1 T&SUV?

[IAJack]

I have been following the threads here on M1's supposed switch. Looks like they might have lost me as a lifelong customer. I am in the comparison stage looking for a new oil. Who makes a true PAO base synthetic oil now -Amsoil? If so what would be the closest formula to M1's T&SUV 5w30

Thanks.

As far as I am concerned, at this time Amsoil's use of PAO is in question. Pablo, a site sponser and Amsoil guru is supposed to be working on posting the facts. Until that happens, the only scientifically proven all PAO based OTC PCMO that I am aware of is German Castrol (GC) 0W30.

The diesel rated 5w30 fom AMSOIL would feel the nich nicely for a severe duty truck &SUV..It is a bit thick though.

 

[Pablo]

Amsoil uses NO, absolutely NO GROUP III basestocks in the premier oils. This means basically ALL the oils except the XL line and the blends.

To answer the question better I'd like to know what kind of vehicle.

As stated by Bryan the closest match on paper is:

HDD HD 5w30

But it could be the ASL 5w30 would work as good or better in your application. Neither contain Group III base oils.

I am looking for a 2000 Jeep Wrangler, 4.0 inline 6cyl. with 87K miles. Outside temps here vary from -40 in the winter to 105 in the summer.

My local Amsoil rep. suggested TSO 2000 0w30 (of course that is the most expensive?)

Not so much that I don't think M1 is still a fine oil but more of a let down that they go the way of everyone else and without really admitting to it or telling us and still charging premium prices?

What Amsoil is closest to M1 T&SUV?

None. If you want to step down to Mobil 1 products you must look elsewhere. And by the way, I agree with your Amsoil rep. You have pretty severe conditions to deal with, and the definition of why to use synthetic oil.

 

[Pablo]

The TSO will work but the HDD will work better.

As will ASL and AFL for less dough.

Pablo,

Which Amsoil is similar to M1 SuperSyn European Car Formula 0W-40 that meets MB 229.5 specs. If possible, tell me 2 vicosities, one is a little thinner and one is a little thicker. I may choose to use thinner oil because the weather in So Cal is very mild, rarely about 90 degree F in summer.

There are some Amsoils that meet MB 229.3, according to this sheet: http://www.whnet.com/4x4/oil.html

Amsoil 5w30 Synthetic Motor Oil
Amsoil 10w30 Synthetic
Amsoil Series 3000 5w30 Heavy Duty Diesel

But none is meeting MB 229.5

Thanks

Not listed on MB (yet):

Amsoil AFL 5W-40

There is a thread on M1 0W-40 vs. Amsoil 5W-40

For a new euro MB Diesel, check this out - not claimed to meet any MB:

Thank you very much Pablo

I am looking very close at the HDD. I am not questioning your advice but can you tell me why you think the HDD would be a better choice for my application vs. the TSO?

I hate change unless it is for the better and it looks like I am on the right path.

 

[Pablo]

The HDD has a much stouter additive package and a bit higher viscosity making it a better fit for your jeep. Your local Amsoil dealer may not know that.

My car is 2000 MB E430. It is recommended to use 0W-40 European Formula or any oil that meets MB specs 229.3; I am thinking about mixing Amsoil 5W-40 with 0w30 for mild weather in So Cal. The OCI will be 1 year/12-13k miles.

 

[Pablo]

My Jeep comments were for IAJACK.

I wouldn't mix the two. Well let me put it this way - I've never tried it. Amsoil warranty won't cover you - but if you do - I would do an oil analysis at 6 months, just to assure everything is OK.

Pablo something is wrong here it seems Oil Changer is unable to see or otherwise comprehend anything you post!

IAJack-
I'm using the TSO in all my cars, and have been for many years now. The HDD is an excellent oil, formulated primarily for heavy duty diesels, and also rated for gasoline engines. This makes it a great choice for mixed fleets that only want to stock one oil. The TSO contains friction modifiers, and was formulated for gasoline engines.
In most of the user reports I've seen, there is a small but measurable increase in fuel economy when changing from some of the other viscosities. For example, my former son-in-law told me he got an additional 50-70 miles per tankful in a Saab turbo after change from AMSOIL 10w30 to 0W-30.
