Oil change question???

The GM4718M spec. prevents them from having to put an oil cooler on their performance vehicles.

I was using Amsoil Dominator in my other car for awhile..
http://www.amsoil.com/storefront/rd30.aspx

ive used Royal Purple, redline, Mobile 1.. i don't notice a difference.. they all synthenic. I just use Dominator cuz read article once saying how good it did on a test.. and my car need best oil i can get.. it goes through turbo spinng at 70K rpms and seeing 1700 degrees..

read your manuals folks, both V-8s need 8 qts of GM4718 grade oil, not GM6094 grade advised for use in the V-6. Read the oil labels carefully to see what grade the oil is regardless if its Mobil 1, RP, Castrol, Valveline or whichever synthetic oil. Most of the 5w-30's oils are 6094 not 4718 as is required for all SS models, read and choose your oil carefully. The warranty guru's might get you if you use the wrong type of oil after they tear down your blown up engine when they find out you used the cheap crap trying to save a few bucks. You didn't worry about dropping almost 40 grand on your car, why scrimp on oil. Also use AC PF48 oil filter.

Royal Purple can not back up their claims.

Read this and see if you still think you want to use it. It tested no better than Castrol.

Truth in Advertising


Excerpt..

NAD recommended that Royal Purple discontinue its use of consumer testimonials reporting specific performance attributes in the absence of reliable independent evidence showing performance capability.

“Anecdotal evidence based solely on the experiences of individual consumers is insufficient to support product efficacy claims, including claims related to horsepower, torque, fuel economy or engine heat,” the organization stated. “While the advertiser may quote from published articles if it provides clear and conspicuous attribution to the publisher, it may not rely on such articles to support efficacy claims for which it has no reliable independent validation.”

Thats why I stick to Mobil1 or Pennzoil Platinum.

Gimmicks and hype.

Who wouldn't claim their engine did this and that after dumping $9 a quart on any motor oil.

Truth is within independent oil analysis.

Thus, I prefer what I read within those analysis. If I could run German Castrol 0w30 in my Camaro, I would. Better than any Mobil1 or PP.

No, my plans are to do it next Friday. I wasn't planning on changing the trans oil yet. I'll reread the post about how much and what oil to use.

Thanks,

I see Royal Purple as the Zaino of oil. Overpriced and overhyped.

$10.00/qt of 5W/30?

OK ... here is something to remember. There are some undisclosed behind the scenes deals that happen between companies. So lets say company A sells motor oil, and company B sells motors.

If company A offers company B a discount on their oil so long as company B is willing to tell their customers that company A's oil was "recommended" by them. Then there is a good chance this deal happens.

Now .. the manufacturer isn't going to recommend something that is 'bad' for their product. But thats not the same as recommending something thats the 'best' for their product.

All the more reason for German Castrol 0w or Redline!

Overhyped? If the guys racing swear by it, then I would not call that "overhyped". Your engines seizes up, you don't finish the race, you don't win any money. They're not about to use the product if it doesn't deliver.

Well the guy that's racing and wins normally showcases the product that sponsors him while he's in the winners circle.

Just cuz he prostitutes himself out to the highest bidder doesn't make the product any better than a name brand oil such as Penzoil or Mobil 1.

I usually find auto stores offering discounts on name brand oil where I can get $30 for oil and a filter.

But if Royal Purple is your placebo go for it.

There is a difference between driving a car and racing a car....

Some of these upper tier lubricants are for the most part overkill for a general use, sometimes seeing 6k redline.

I personally will stick to a top tier group III or IV base stock synthetic and filter. When someone shows me indisputable unbiased proof that Redline, Amsoil, Royal Purple is better than Mobil1, Pennzoil Platinum, German Castrol cost for cost, additive per additive, benefit for benefit.

Oil is just like performance....why spend $15,000 for a Magnuson at Lingenfelter for another 150 HP if you never use it? These top tier lubes are specifically processed for high stress purposes. If it makes you all warm and fuzzy spending $5 more a quart for these lubes, so be it. I myself have over 700k on PP and M1 and GC and have had 0 issues with any/all of the three and with Blackstone Labs analysis to back up the wear and performance of all 3.

Yea, but Ferrari recommends Quakerstate.

Hey Doc,
You're right man....Royal Purple is super-duper oil, has all the great lubricating properties you could ever look for, has a great reputation, and they sponsor many race teams, it's truly great stuff I'm sure.
However, there's just one little thing missing......ROYAL PURPLE DOES NOT HAVE THE GM-4718M CERTIFICATION. It says right in the owners manual that any damage sustained while using anything other than GM-4718M certified oil may NOT be covered under warranty!!!! Why would anyone in their right mind want to jeopardize their powertrain warranty??? I suppose if you have already done modifications that have already voided the warranty, then it's no big deal to use whatever. But I think a majority of us still have and cherish our warranties. So, use the RP stuff all you want, but common sense tells me to use Mobil 1, or any other oil that has the certification. Just leave it at that, if you want to say it's great stuff, that's fine. But trying to defend an oil that could void our warranty doesn't make much sense to me. Sorry man, don't mean to "dog" you out or anything, just saying my opinion. To each his own I guess.
