What type of oil?

Ok. Just bought a 2010 Camaro 2SS/RS and the dealer told me to use Synthetic Oil. What brand do you guy's most recommend?

I don't have a clue!!

After break in I recommend and personally use Royal Purple. Mobile 1 is good stuff too.

Do a search. Plenty on the subject including a letter from "Royal Purple" indicating that it does not meet the waranty requirements of General motors.

EDIT: the link:http://www.camaro5.com/forums/showthread.php?t=77937

Here is my reply from royal purple


Good Afternoon Mr. Bird,

The oil specified for your Camaro is a 5W-30 that has the API Starburst symbol on it. Also, the oil must meet the GM 4718M performance spec. All Royal Purple motor oils meet or exceed the performance requirements of GM4718M, and GM6094M. The GM 4718M spec is largely an oxidation testing sequence GM began using back in the mid to late 1990’s with the introduction of the C5 Corvette. The new design created some inherent issues with oil cooling. GM needed an oil which could handle higher temperatures for extended periods without a significant increase in the oxidation rate. In 360F Thin Film Oxidation Uptake (TFOUT ASTM D4742) testing, Royal Purple SAE engine oils exceed 1200 minutes before failure. Most synthetics, including GM4718M licensed Mobil 1, will typically reach failure in less than 500 minutes.

The GM 6094M specification is a low temperature cold cranking viscosity. The pumping viscosities specified by GM6094M are shown below. The Royal Purple pumping viscosities are shown for comparison. I have also attached the Royal Purple motor oil data sheet:

GM6094M:

For 0W-XX oils - 30,000 cP@ -40°C
For 5W-XX oils - 40,000 cP@ -35°C
For 10W-XX oils - 50,000 cP@ -30°C

Royal Purple:

For 0W-40 oils - 20,000 cP@ -40°C
For 5W-20 oils - 22,200 cP@ -35°C
For 5W-30 oils - 34,800 cP@ -35°C
For 5W-40 oils – 21,500 cP@ -35°C
For 10W-30 oils - 18,000 cP@ -30°C


Higher numbers indicate a thicker, or more viscous fluid. As can easily be seen, Royal Purple motor oils have much better cold flow (lower pumping viscosities) than required.

Even though Royal Purple motor oils meet or exceed the performance requirements of GM 4718M and GM6094M, we cannot list certification because the GM specs also require an API SM rating. We also can not show the API Starburst logo because we do not carry the API SM rating. We have held most of our motor oils back from API SM (most RP SAE motor oils are API SL) because of the lower amount of anti-wear additive allowed in API SM/ILSAC GF-4 oils. The reason for the restriction on anti-wear additive is that certain components of anti-wear additive were shown to cause premature degradation of catalytic converters. OEMs are now mandated by the EPA to warranty the emission system separately from the power train. Rudimentary experimentation showed certain anti-wear additives do in fact degrade catalytic converters; however, the anti-wear additive was applied directly to the core of the cats during the tests. If enough oil is consumed in the combustion chamber (i.e. through poor piston ring seal and/or leaking valve seals), there can be degradation in catalytic converter life. This is not an issue with Royal Purple motor oils used in a mechanically sound engine. The OEMs are willing to trade the longevity of the engine for a possibility of extending the life of the catalytic converters.

We do not agree with reducing anti-wear protection for the engine. For our customers who have vehicles under an OEM warranty that require API-SM rated oils, and have chosen to use Royal Purple API-SL oil, we offer a corporate warranty in the case that engine damage or failure is directly attributable to Royal Purple Oil. I have attached a copy of the warranty for your review.

<B>In summary, Royal Purple motor oils are not currently warranty compliant for your Camaro. If strict warranty compliance is your primary concern, we may not be the best choice.</B> However, if performance and protection are your primary concern, Royal Purple SAE 5W-30 (part #01530, quart bottle) would be an excellent choice.


Thanks for choosing Royal Purple and have a great day!


Best Regards,

Christopher Barker

The only way that could come into play is if there was an internal wear issue, which Royal Purple offers their own warranty against. If you've ever seen engine internals that have come out of a car running Royal Purple you would immediately recognize that wear is not an issue. I've been using their stuff and recommending to others for about 7 years now and have never had any issues, only raves. I've also achieved results similar to those in the video below.

The only question I have is , why pay a premium for something that you can buy for less and is just as good??

In fact, if you want to pay a premium and get a better oil, get Amsoil, The original synthetic.

GM loyaltists use use Mobil 1 because that's what GM says to use

Lots of internet people and ricers like Royal Purple

People who do research usually run Amsoil

People who do MASSIVE research and usually have oil forums as their homepages go with Penzoil Ultra

People who dont mind spending a good amount of coin for the best stuff out there, get Redline

Figure out which group you fall into and go with that oil. lol.

While you warranty is active and if you care about not voiding it: Mobil 1, Pennzoil Ultra, or Pennzoil Platinum.

When your warranty runs out or if you don't care to void it: Amsoil

Actually, it comes into play immediately. It doesn't meet the all the requirements set forth in the manual, therefore, it voids the warranty if used. Pretty simple.

Now, how can GM know that you used a oil that didn't meet all requirements stated in the owners manual? Damn near impossible...even if they took an oil sample.

I agree, that is why I made the previous post.

If your looking for good high performance oil take a look in to eneos 0w-50 Great oil.

No, it is not false. The only exception is Amsoil's XL line. Meeting the specs alone doesn't mean jack as far as the warranty is concerned. The owners manual is clear:

What Kind of Engine Oil to Use
(V8 Engines)

Look for three things:
. GM4718M
This vehicle's engine requires a
special oil (1) meeting GM Standard
GM4718M.
Oils meeting this
standard may be identified as
synthetic. However, not all
synthetic oils will meet this GM
standard. Use only an oil that
meets GM Standard GM4718M.
Notice: Using oils that do not
have the GM4718M Standard
designation can cause engine
damage not covered by the
vehicle warranty.
. SAE 5W-30
(2) SAE 5W-30 is best for the
vehicle. These numbers on an
oil container show its viscosity,
or thickness. Do not use other
viscosity oils such as
SAE 20W-50.
. American Petroleum Institute
(API) starburst symbol
(3) Oils meeting these requirements
should have the starburst
symbol on the container. This
symbol indicates that the oil has
been CERTIFIED by the American
Petroleum Institute (API).


The it CLEARLY says:
Notice: Use only engine oil
identified as meeting GM Standard
GM6094M and showing the
American Petroleum Institute
Certified For Gasoline Engines
starburst symbol.
Failure to use
the recommended oil can result
in engine damage not covered by
the vehicle warranty


Neither Amsoil, Redline, nor Royal Purple comply with the last one except for Amsoil's XL line. Period. Stop spreading your lies!
