German Castrol is the most exotic I have ever gone.

all i use is Mobil 1 Fully Synthetic with some Lucas Synthetic

I was wondering about oil too.

I got a 2001 Firebird V6 3.8L and im due to change oil in like next week. I do it myself. Last time I put like 10W-30 or so but my mechanic told me to put 20W-50 next time. Is that good? What kind of oil should I be putting on a car with exactly 85k miles?

After seeing the internal condition of a LT1 Corvette at 60K which is run on all Mobil 1 versus the internal condition of other non synthetic LT1 run with half that. I am a total believer in the superior formula of Mobil 1, after all the best performance cars out there call for it, the only downside might be seals that don't last as long but its worth a few leaks in my opinion.

Rumor has it....

Mobil 1 is no longer 100% synthetic. This is since Katrina.
I guess they are using a lower grade basestock oil which is not 100%.

This doesn't mean the oil isn't good, just that it is overpriced.

I believe its just that, a rumor. It states on there bottle as well as on the site that it is a fully sythetic motor oil. If this was not the case, seeing as how Mobil 1 is the most saught after sythetic oil by the average car guy, the competition would be all over this.

[Mr. Luos]

Mobil1 is no longer a 100% Group IV Synthetic PAO basestock. This all started post Katrina when Mobil1 announced it's PAO plant was whacked hard. Virgin Oil Analysis began popping up on various boards refelcting Group III basestocks with drops of GroupIV PAO's. Pennzoil Platinum did the same thing....went to a Group III basestock in November 2005 by the way. And I do watch many boards and forums outside of BITOG.....(which has turned into a zoo by the way).....I read the corporate reports of Exxon-Mobil and Shell.....so I research and get my info from more than the Internet and VOA's....
I wrote a letter to Mobil asking if their basestock was still 100% Group IV and got a "canned response" like others word for word by the way....
" Mobil 1 motor oils are 100% synthetic, utilizing the PAO basestock and proprietary blend of additives that is tailored specifically for each viscosity. Mobil does not discuss specifics about our motor oil formulations."

You want to know why I have an issue with that statement? Because Mobil Pre-Katrina always said and advertised they used Group IV basestock exclusively. "Utilizing the PAO basestock...." is not the same as "Exclusively using the PAO basestock..."......that is a change for sure....the other thing that has me convinced Mobil1 is now just another synthetic "blend" is they are now advertising they utilize "Synthetic Technology"....
So.....Mobil in their Corporate Report admit to disaster at the plant that made the PAO basestock ( which Amsoil buys there by the way). VOA's clearly show a reformulation with Group III showing up. Mobil has changed the way they "express themselves" now. Mobil1 now sells it for like $5-$6 bucks a quart for a Synthetic Blend oil. And that is a rip off as they are now just as guilty as those they sued and litigated against years ago.
I remain an advocate that Mobil1 is good oil. However it is very very overpriced for what it is now. Lot better oils out there for less money for sure.

Hope that makes some sense.
Now of course....this isn't 100% fact. This is one old car guys opinion on it. But he has never steered me wrong.

Just in......from a "oil board" and the author is a known chemist guru.....

Okay boys and girls, take a seat cause you aren't going to like this.

The new M1 EP 5W-30 SM dated Oct 2006 just came out of the G.C. and it is MOSTLY mineral oil, presumably Group III. It also contains a good slug of AN and some PAO, but little or no ester. Will have more data tomorrow.


And Mobil has changed its spec sheets on the 5-30 EP....
"PAO + hydroprocessed."
BY the way GC is Gas Chromatograph....cuts through the shit machine

After all these years of Mobil1 crying about other "Synthetic Blend" brands selling as Full Synthetics.....they go and do this.....just goes to show you what money and greed will do.

I am not discrediting your source but I have read lots of knowledgable members from lots of boards get info wrong or mixed up. I agree the plant damage along with some minor tweaking of statements makes things look fishy, however nothing posted can be viewed as fact (as you stated). The sad part though is probably most independant testing publications wouldn't run this test due to Mobil being a huge marketing company and possible legal action of damages to sales.

well I was also wondering if anyone here has tried Royal Purple; or atleast heard any +/- reviews over it.

You wouldnt think Mobil1 would do it, though.

I would stick with 10W30....xcohiba

Don't use royal purple.. If you really want to know what oil to use visit Bobistheoilguy.com General conses is German Castrol Syntec is hands down the Best oil out there. Mobile1 is a good alternative altough on the viscosity level is the at the extreme light end of the weights. Hope this post helps. I use German Castrol and if I can't find it I use Mobile 1 with a WIX filter.

K&N has some nice high flowing oil filter also.

ive used K&N but really had no use for it at 12$$ a filter.

also where could I find some of that "German Castrol" ???

[Mr. Luos]

AutoZone I guess carries it.

I use Delco filters.

[viperh]

German Castrol is found at Autozones. You need to grab the castrol syntec bottle and look on the side if it says Made in Germany thats the shiznit. If it says North america it is shit.

I have no use for a 12 dollar oil filter myself which is why I run WIX. Every oil change I ship oil off to get an analysis done and I cut open the filter to have a look see.
