Sounds good.
I knew the Grand Am was going to that once I ran out of Mobil 1, but I wasn't sure about the T/A.

Thanks again man!

I use Mobil 1 in mine and I get the fully synthetic 5w30 @ Costco for 4 bucks a quart. They can't call it fully synthetic if it's not. Besides your gonna buy what you like anyway. As long as Mobil 1 meets the API standard I'll use it.

Yes they can call it 100% synthetic with conventional base stocks. Check out the lawsuit between Castrol and Mobil. Conventional base stocks are cheaper and it appears that is exactly the route Mobil1 went. Cheaper basestocks and yes...they can call it synthetic even when it is not 100% PAO.

hey sarge thanx to you im a amsoil perferred customer now, just ordered a case of 10w30 for my 02 SS MOBILE1 TO AMSOIL HEY SARGE WHAT FILTER YOU RECOMMEND? AKA ABBY

**Mr. Luos** · 05-05-2007, 09:13 AM

So wait....you switched?
You called bullshit on me when I said it wouldn't be a bad idea.

I run with Delco filters.

I have always heard that you should stick with the GM/Delco filters...either factory or the slightly oversized one if you have decent mods...however the longer filter pokes out below the factory oil pan so beware.

Perhaps Sarge will be able to suggest what's best. I'm pretty much factory so I'm not too worried about a larger filter yet.

**Mr. Luos** · 05-05-2007, 09:46 AM

The larger filter is so you can run more oil.
I fill to 5.75 quarts anyways....and I run the regular sized filter.

so what im getting out of this is that i should run pennzoil 10w 30? i only have a cai and catback as of now, but headers, cam, and ported heads are right around the corner. i run castrol 5w 30 synthetic blend to transition to fully synthetic bc my cars previous owners used non synthetic. i hate to be redundant, but please school me on what to use....

**TASWEET SS** · 05-05-2007, 11:51 AM

you cant go wrong with the godfather of synth. amsoil

**TASWEET SS** · 05-05-2007, 11:55 AM

yes im switched, i finally opened my ears instead my mouth, sarge knows, and ive always heard good shit about amsoil, i assumed mobile1 was the shit, but sarge changed my mind, i still might use the same oil filter mobile1 #107 i think, thats what i always use for synth oil.

WTF> Look guys...you can switch to a full synthetic at anytime. There is no transition required nor needed. You can stick with Castrol 5-30 blend till the cows come home and you'll be OK. The top tier synthetic motor oils just protect/clean better...provide better cold start protection....have better dispersant characteristics ( more crap to the filter versus in your oil galleys) and is much more shear resistant.....but if you want to utilize a cheaper or less expensive solution by all means go for it....just change your oil more often....
Bottom line is many have some serious investment in their motors and if a top tier lube change cost $50 so be it.....others may not have that kind of money and should feel just as good on Pennzoil Conventional motor oil in the yellow bottle from WalMart at $2.19 a quart in their motor as long as they are adhering to the 3month 3K mile Oil Change intervals.....as for oil filters....AC Delco is as good as most....NAPA is better for flow and filtering....Mobil1 is overpriced for what it is and a WIX/AC Delco is just as good in filtering and flow....I use Amsoil filters...but I am crazy and my wife is rich as shit so I dont care.......just do not use Frams or I will hunt you down and kill you to keep your genes from spreading into the general population.....

**SSpdDmon** · 05-05-2007, 12:57 PM

M1 - no
Royal P - no
Castrol Syntec 0w30 (full synthetic made in Germany) - yes!!!

**riceslayer302** · 05-05-2007, 01:06 PM

my mustang leaks so much oil it doesnt matter what kind i put in it...

**TASWEET SS** · 05-05-2007, 03:18 PM

thats a good reason to go buy you a CHEROLET TODAY, AND COME ON OVER TO THE OTHER SIDE, VERY WISE DECISON

**GatorSS** · 05-05-2007, 05:28 PM

Hey Sarge, do you still like the AmsOil S2000 line? I, too, have quit using the Royal Purple oils based on your info (didn't use it for that many miles or any real hard use, so I'm still 'safe').

Also, I still have a case of VP Racing RS530 and half case of Schaeffer Supreme 7000 20w50 -- how do you think those stack up against others?

And another one, what do you think of a 'soup' recipe using Penzoil Platinum and any of the above along with a little Valvoline Synthetic Oil Treatment?

The Amsoil 2000 series is an excellent value with outstanding add packs for sure. VP or Schaeffer's are both top tier. I don't like mixing. I have learned we/you dilute the add packs of both oils by doing this. I used to mix and never really got any benefit from it via UOA's....I learned I guess......
I must share something though....I have been in contact with Royal Purple.....on the shearing issue....I shared UOA's and they have assumed the position everybody who experienced shearing with Royal Purple was using the wrong weight (viscosity)......unreal....multiple motors and multiple folks...all dismissed as using the wrong viscosity......even when I pointed out the viscosity used was recommended by the manufacturer and by Royal Purple.....talk about ignorant responses.......

Short and sweet -

Sarge, in days ago Pennzoil was not exactly touted as the best oil on the planet, Quaker State and Valvoline called better.

I realize Pennzoil bought Quaker State.

#1 Pennzoil (new) vs Valvoline

#2 Please elaborate on how Mobil can now claim 100% synthetic?

At this point I'm tempted to seek out an old favorite and blend it, remember Klotz?
