AMSOIL Signature Series Engine Oil
If you are interested in or considering using AMSOIL products in your vehicle, this thread will explain the benefits and features of that product.

Specifications:
Application: Cruze 1.4 Turbo (4.25 quarts) and 1.8L Engines (4.8 quarts)
Recommended viscosity: 5W-30 (for most climates) or 0W-30 (for especially cold climates)
Meets DEXOS1 and GF-5 specifications as follows:



Benefits:
- Lower operating temperature through better heat transfer and reduced internal friction (traction coefficient). Since the 1.4T features an oil and water cooled turbo and piston cooling jets that are cooled with engine oil, a lower operating temperature will increase longevity and reduce long term maintenance costs.
- Extended drain intervals as follows:
- 1.4 Turbo: 15,000 miles or one year, whichever comes first. Filter change at 7,500 required.
- 1.8L : 15,000 miles or one year, whichever comes first, under severe service driving conditions. 25,000 miles or one year, whichever comes first, under normal service driving conditions. Filter change every 7,500 miles required.
- Small increase in fuel economy. Based on engine-only testing in stop and go diesel fleet trucks, I would conservatively estimate this to be an approximately 0.5% to 1.5% improvement.
- Easier cold starts and better fuel economy during warm-up times in cold weather.
- Superior wear protection, especially under severe service conditions.
- Reduced oil consumption under severe service conditions and extended drains.
- Exceeds Dexos1, API SN, and GF-5 specifications.

AMSOIL Signature Series engine oil is a group 4/5 based true synthetic lubricant that has no equal in the industry. Mileage guarantees are backed by an engine repair/replacement warranty by AMSOIL should the lubricant fall out of OEM specifications within these durations. Owners save money with AMSOIL through extended drains and reduced long-term maintenance and repair costs. Extended drain intervals reduce environmental impact. All AMSOIL products are made and packaged in the USA.

Warranty Information:
The AMSOIL warranty certificate can be found using the following URL: AMSOIL Warranty

Frequently Asked Questions:
Q: Will going 15,000-25,000 miles on an oil change void my powertrain warranty?
A: No. A: Regardless of what your dealer may tell you, the Magnuson-Moss act protects you from having your warranty voided by using a product other than what the dealer recommends or at a drain interval other than what the dealer recommends. If there is a failure, GM has to prove that the fluid's condition was outside of OE specifications at the time of the failure and that the difference caused the failure. Should this ever happen, AMSOIL's warranty will take effect.

Andrei,

I'm going to nitpick the chart and the claim "exceeds". Based on the chart it appears the AMSOIL Signature Series oil meets the higher of Dexos1 or GF-5 but at no point does it ever exceed both. My suspicion is the chart is wrong because AMSOIL simply didn't test for exceeding the higher numbers, just that it met them.
I am for amsoil but where did this chart come from? To be honest I can make a ton of charts for my amazing athletic abilities however I have next to non lol.
It's true that the diagram kinda doesn't represent Amsoil well.

It looks a little like someone in marketing said: we'll just shade these areas in. It doesn't give the feel that anything has been idependently tested and accurately plotted. Quite honestly I would have expected Amsoil to exceed all ratings and not appear as a sort of one-size-fits-all universal option.

As for their product I've started thinking about my diesel transmission.
Should have noted meets as opposed to exceeds. It is the correlation of the graph's purpose that was incorrect, not the statement made.

The chart itself was produced given the oil meets dexos1 and gf-5 specifications. I'm not sure who actually made it. The format of the chart is an API standard unless I'm mistaken. Search for "api gf5 chart" in Google images to find more. AMSOIL does exceed both specifications as demonstrated by areas where the two overlap. Where gf-5 exceeds dexos1, so does AMSOIL SS. Where dexos1 exceeds gf-5, so does AMSOIL SS. The chart doesn't intend to reflect by how much nor do I believe it is accurately to scale.

I updated the wording.

I see its just demonstrating what is already know rather than proving, its obvious now that I read in to this the wrong way originally.

Quick question, I'm in Anchorage, Alaska and will be doing my first oil change since being in state... Should I use 0W or 5W? Temps right now are mid-20s but will drop close to 0 in deep winter.

Thanks,

Go ahead and run the 0W-30 if you expect a lot of very cold starts. Both will work fine but 0W-30 will start a bit more easily.

The W in 0W-30 motor oil stands for Winter and indicates the oil meets or exceeds certain criteria for good low-temperature performance. Motor oil with SAE viscosity grade 0W-30 behaves like an SAE 30 oil at high temperatures and SAE 0W oil at low temperatures, providing the necessary fluidity for rapid starts and efficient engine operation at low temperatures.



Here is what is in my 2012 Sierra Owners manual.

The 2014 Cruze Owners manual has a similar statement:

2014 Cruze Owners Manual Second Printing Page 10-13 said:
Viscosity Grade
SAE 5W-30 is the best viscosity
grade for the vehicle. Do not use
other viscosity grade oils such as
SAE 10W-30, 10W-40, or 20W-50.
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below −29°C
(−20°F), an SAE 0W-20 oil may be
used. An oil of this viscosity grade
will provide easier cold starting for
the engine at extremely low
temperatures. When selecting an oil
of the appropriate viscosity grade,
always select an oil of the correct
specification. See “Specification”
earlier in this section.

Does anyone know where you can get Amsoil for less than $20 plus a quart ?

Use the links from the original post! :)
What comes up in the links from what I am seeing is not Dexos certified

An oil doesn't have to be dexos1 certified, it has to simply meet dexos1 specifications. Check your owner's manual, you'll see the same.

As soon as you see the word "certified" in any form, you immediately add to the cost of the item. You can meet/exceed the certification standard but if you don't PAY for the certification, you cannot claim to be certified.
5w30 Signature is $51.20/gallon.
$38.55 if I log into my preferred customer account.
Talk to XtremeRevolution about becoming preferred.
