royal purple is the best

 

Royal Purple uses Sodium Sulfonate in their oils which is frowned upon by most major manufacturers because it is hard on a lot of metals used in today's engines.

Just as a side note for 2.2and 2.4L guys who don't want to use Syntethic, Havoline (Texaco, which is owned by Chevron) is an excellent dino oil for our cars as well.

Synthetic Oils in General will give a bit of an MPG boost because it is more stable than traditional dino oils and doesn't thicken quite as much when you start putting miles on it.

You can visit http://www.blackstone-labs.com/ and request a sample kit to have your oil tested and see how it is holding up as well.

 

Yeah I am torn as to whether or not to go synthetic on this car. I've always been a every-3000-mile oil change guy, no matter what, so going to a synthetic would either be a MAJOR change for me (because of the longer intervals) or a waste of money if I stick to the 3000. Its so ingrained in me that if I knew I was pushing 6000 or 10,000 miles I wouldn't be able to stop myself from changing it early.

Oh well. I always used to make fun of kids on the forums who inherit mom's clapped out Accord, and right away put in Mobil 1 for the very first time, like it was some sort of exotic. Never mind all the abuse and missed oil changes the car suffered back when the kid was 12 and couldn't care less about cars - I don't think switching to synthetic at 170,000 is going to save it now. But for me - I have a cool new SS and just may be making the switch for the first time in 25 years of driving.

 

For my wife's car we'll probably just stick with dino and get it changed every 3k. If I happen to get an SS when the time comes I'd probably switch to synthetic and just change it out when the oil life meter ran down to 0.

 

Ok no insult was intended but **** happens and I run racing 11 lite royal purple wich has a viscosity of 0w10 AKA water in some nasty racing enviroments mobil1 would not last no way no how and its a heavy viscosity and after almost a season my internals are perfect cant say that for mobil 1 lost cam bearings with it so royal purple = BETTER.....

 

That's fine and all and you can use what you want
BUT
Royal Purple DOES NOT MEET GM4718M STANDARDS
Since this is outlined by your SS/SC owner's manual as a requirement of your warranty you risk having your engine warranty denied by not using a synthetic oil that has achieved this standard.
(There's a list of GM4718M approved oils provided to all GM dealerships)

Bad, I'm surprised they even warrantied your engine if they knew it had RP...Lucky!

LOL Thats not true I have a case of it on my desk and it says right on the bottle that it is GM4718M approved so royal purple will not void your warranty..

 

mmm hmmm. I use Castrol Syntec 5W30. Does the trick and my engine builder recommends it.
The Hendricks Motor Sports Team uses Castrol! *GO JIMMIE JOHNSON!*

And ya, just don't forget to do the break in period first before going synthetic, that makes a difference.

 

What's on their bottle is meaningless
Royal Purple IS NOT on the GM4718M approved list (as of Mar 2006)
(actually RP's supposed "label printing error" was reported last fall - theres a TAC case against it)
ROYAL PURPLE WILL VOID YOUR WARRANTY

I wonder who pays off gm to use their oil uber giant mobil or smallroyal purple HMMMM whatever royal purple shats on mobil1 regardless.

 

LOL
Conspiracy Theories!!!

Shat on it if you wish, but there's very good reasons why Royal Purple (or AMSOIL for that matter) wont meet GM4718M
SOME of these are actually environmental and related to sulfer content

You can certainly use whatever you want- it's YOUR car
Just dont expect any engine warranty if you cannot provide documentation that you purchased/installed an approved oil for your LSJ

Here's the current approved synthetic list

I have silly question: I have a 2.2 and my "oil life" in the display is at like 58% and have 3100mi+ on the car, so that means it already has synthetic in it correct?

 

Royal Purple is definitly some good oil. One of the drag race teams I worked on would run Mobil 1 normally but switch to Royal Purple when racing a particularly formidable opponent. It was always worth 3 hundredths or so (.03).

As far as a street car, just run Mobil 1 in it. Why pay $10 a quart??

 

No. The 2.2 came with dino from the factory. Normal oil lasts longer than what we are used to for changes.

 

oh i get it cheap because we buy it in bulk for our race cars.

 

OH and now that I think about it royal purple dose have a high sulfer content which is hard on CATS and emissions systems but the sulfer is what makes it good.

 

How about Amsoil for the 2.4L (GM 6094...I think)...is that on GMs approved list?

 

Simply put, a dealer CAN void your warranty with anything not GM approved. They could, if they wanted to, void it for not using mobil one like it states. Regardless of what people think about which oil is best, there's a reason GM uses it in their cars. It's funny, it comes standard in the C6 Z06....
WOT, don't they use it in the C6R as well?

 

Nope. The oil life system goes by how you drive the car, not the type of oil you use. IF it were me I'd go ahead and change it every 3k unless you switched to synthetic. If you switched I'd go ahead and follow the oil life meter.

But that is just me. A lot of people follow the oil life meter and have no problems.

 

^^^Thanks for the response, looks like its time for an oil change

 

Mobil1 is an excellent oil. Don't know why someone would use something else.

 

Sorry Av
Wasnt intentionally excluding the 2.4 or 2.2
Here's a link to the current GM6094M listing
GM6094M and GM4718M Approved Oil Standards

Unfortunately again Amsoil (much like RP) is absent from the list due IFAIK to certain sulfer by-products / additives in their formulation.
I've been using Amsoil since the late 70s and it's great oil from a lubrication standpoint, but these companies have to step up to the plate when it comes to their environmental responsibilities (just like the larger manufacturers have had to do)
Sulfer is being yanked out of our fuels and oils for very good reasons- but as long as they can get away with it they will I suppose.

PS> BadSS , Yes the C6R Corvettes will be using Mobil 1 this weekend at Le Mans in fact
(They qualified 3rd and 6th in GT1)

so the 2.4 comes with synthetic?

 

no--it comes with dino oil. ONLY the S/C comes with factory synthetic.

 

ok cool.. thnx
