Synthetic Oil

The Mfg can not deny warranty unless they prove it was "Oil" related. I run AMSOIL and change it around 10-12,000. Just because I don't follow GM specs in the Owners Manual doesn't mean they can deny me service. It's the same for a lot of "aftermarket" parts.

There is a Federal Act the Moss-Magnusen Act, this Act gives the consumer rights against the warranty and service contract companies. It specifically says no company can deny warranty service because the consumer uses custom parts, or other parts from somewhere other than the manufacture. They ONLY way they can deny you service is if they can prove your modifications caused the problem. In most cases, there is no way they can prove anything. The same goes for oil changes.

People PREACH and Preach about Magnusen-Moss, but in the end, if you have to try and act on it; YOU are the one paying the expensese to prove the dealer or mechanic wrong. They won't just instantly go "ohh, well there's that act, ok let us investigate this so we can be proved wrong." It'll come out of YOUR pocket and YOUR time to have it proved the part/oil/whatever was NOT the cause of your parts failure. In the end, you can preach Magnusen-Moss all you want but it'll get you nowhere without pockets to back it. They have to prove nothing, there's an aftermarket non OEM part in your vechile that didn't come from the factory. That is *ALL* they need to deny you warranty service.

AMSOIL oil and filters all the way. I do the long intervals, and do pretty severe driving (stop and go for 94 miles daily).



They're meant to work together, and Autopians know all about systems or products that work well with each other :cool:



Yes, I'm an AMSOIL Dealer, but the important thing is that I "eat my own dog food" when I could buy cheaper oil and filters. My car will thank me by living longer.
 
I seem to recall reading something some time back saying that AMSOIL was rather snake-oil-ish. I've just stuck with Mobil 1 Synthetic.

That's why no aftermarket chipping, air filter, etc for me. Any parts I'll buy if needed when car is under warranty will be OEM, Audi/ VW I hear, makes *at least* decent OEM filters any way

Most motor oils & filters work fine in modern engines up to say 5-7.5k miles for sure & synthetics will likely last longer all things being equal. The problem is not that the oil breaks down, it's that air & gas blow by the pistons (since the firing chamber is not hermetically sealed) & into the oil. The oil soaks up most if not all of this, but if you leave the oil in too long it becomes saturated w/ this stuff & you get varnish build-up. Many people, for peace of mind, cut the oil service interval in half for this reason, particularly for some cars with 15k oil change interval recs in the owner's manual.

Totally agree with all you are saying. Older cars are even worse for blow by. There is a kind of person who will spend money on "the best" not realizing they are gaining maybe -1% improvement when they would have been much better off with an oil change more often. My BMW R/75 runs smoother in summer heat with Castrol straight 40 then with Castrol 20-50...which I use in "winter" around here. I have used straight Synthetic but found it's was so "slippery?" it got past seals easier or something. Couldn't figure why it weeped and regular oil didn't.



There is an OIL site, can't think of it right now, that oil guys post, etc. These guys are serious about oil! Anyone know this site?



I found it once trying to find out about a new Honda for when to do a first oil change. 7,500 in the manual seemed WAY TOO long to me....but there was an interesting thread about how on some of these new cars with their incredible tight tolerances.....(5-20 oil ONLY in new Accords)....changing TOO soon isn't good either, go figure. But, they had the data to back it up and I was blown away by these guys dedication to oil science!





...If you find this site I'm sure your'll find oil answers. Just want to pass on the "OIL SITE" thing. If I find it here soon, I'll add an edit.

AFAIK Audi/VW use Wix filters, which you can get at Napa (This atleast pertained to the MKIII generation). I'm not sure if the MKIV's still use a wix filter.
 
I bought a 5 pack of official VW/Audi filters from Clairparts.com. They are *exactly* the same as the original one from the factory. :xyxthumbs
 
The primary OEMs for VW/Audi will be Mahle, Hengst, Knecht or Mann-Hummel. All in this group are good.
 
royal purple motor oil is wayy too much hype and overpriced, (I like the gear kube though)



the fram in the can someone mentioned is the x2 which is a pretty good quality filter but really expensive at $12each



I want to try redline motor oil but I am scared it will mess stuff up, I have heard it is the best thing out there, but others say it is the work of the devil.



I'm sticking with mobil 1 full synthetic for now.

If you think RP is pricey, wait till you see Redlines Prices.



You should check out bobistheoilguy.com and read their UOA(Used Oil Analysis) for Redline on some particularly built/modded motors. It's getting some great marks, but it's not showing much for longevity; but as far as keeping you engine wear minimum it's definately up there.



This thread (2 weeks ago) sparked me to start reading BOTIG and I've learned a lot, I'm going to give AMSOIL 5w40(european blend) a go for my next two oil changes, it's also getting very nice UOAs.
 
I started reading BITOG too. It's clearly the authority on motor lubrication. I'm going to try to track down some German Castrol Syntec 0w-30 for my 1.8T

Fram is the worst oil filter on the market. I don't have the link that did the tests. Mobil 1 and Purolator were rated as the best.

This is probably the link you're referring to:



http://minimopar.knizefamily.net/oilfilterstudy.html



Per manufacturer, Purolator Pure One filters a bit better than Mobil 1, but Mobil 1 is 2-to-3 times the price. Personally, I use Purolator Pure Ones.



+++++++++++++++++++++++++++

Mobil 1

M1-301



Like the Champ filter, this filter is made by Champion Labs. However, it uses a unique end plate and a thicker can that make it the strongest filter available for wide distribution retail sale. It also uses a synthetic media, which inproves filtration and flow. I'm happy to say that this filter is not a fake. It is definitely a unique design.



It uses a synthetic fiber element that can filter out very small particles and is very strong. It is rated just under the Purolator Pure One as far as filtering capability, but is still very much above conventional paper filters. It also has a very strong construction to withstand high pressure spikes during start-up. However, as with all Mobil 1 products, expect to pay 2 - 3 times as much for this filter.
