New line just came out. This line is mainly to compete with other synthetics used in the quick lube market. Only intented to be used at OEM intervals. Prices are set to compete with the others as mentioned.
Just an option for those who want to use a syn but want to stick with OEM intervals. Is API certified and meets new API SN and ILSAC GL-5 specs.
Here's a link:
AMSOIL OE

 

This is a very cool oil! I use Amsoil for the extended drain intervals, so it's not something that I would use, but it is a good oil to be used in competition with the quick lube places that are using the less expensive oils as well...

Heath,

Whats the difference between OE and the XL oil? Dodge now only allows a maximum of 6K for oil change intervals for car engines, if you go over 6K you risk voiding the warranty, so I see no need to buy the higher priced 25K oil.

 

The OE is just a "cheaper" version of the XL. The XL was beefed up a bit to go 10k or six months. The main difference is the TBN is a little less with the OE(7.9 vs. 9) so it doesn't last as long. It's intended to run the OEM intervals, whatever they may be.
An OEM can not void a warranty based on intervals either. The only way it can be voided is if the oil is tested and found to be the casue of any failure.

 

Heath is right on this one.. The only way a dealership can technically void a warranty due to extended drain intervals is if they PROVE the oil caused the issue. Of course, in order to get it fixed under warranty, you may have to fight the dealer for it, but as you probably know, Amsoil does also have a warranty on their products as well...

Here is the exact wording used in the owners manual for oil changes:

Change Engine Oil. The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance. Refer to “Maintenance Schedule” for further information.

NOTE: Under no circumstances should oil change intervals exceed 6,000 miles (10 000 km) or six months, whichever occurs first.

Engine Oil Selection. For best performance and maximum protection under all
types of operating conditions, the manufacturer only recommends engine oils that are API Certified and meet the requirements of Chrysler Material Standard MS-6395. Lubricants that do not have both, the engine oil certification mark and the correct SAE viscosity grade number should not be used.

Synthetic Engine Oils You may use synthetic engine oils provided the recommended oil quality requirements are met, and the recommended maintenance intervals for oil and filter changes are followed.

 

I'm not here to convince anyone to do otherwise, just want to make the point that dealerships can't tell you want to use and how to use it unless they provide it free. Yes, you must comply with the API rating but it does not have to be certified.
Some are comfortable with this and some aren't. If any dealer tried to tell me I couldn't go 15k with my oil because that was too far or it wasn't certified, they'd be in for a rude awakening, especially if I had the OA's to back it up.

The verbage is there to scare people but it says nowhere that the warranty would be voided.
Same reason jiffy lube tells everyone to come back in 3000 miles....money.
