Lower filtration rate and they don't have a saftey valve inside them so if the filter ever got clogged............................BOOOOOM goes you engine.
Factory filters won't do that, it will by pass the filter so you won't lose oil pressure.
Happy now?

 

haha yeah thanks auditech79...

 

Im about to do another oil change in my car. Anybody ever try royal purple synthetic in an audi? Ive heard great things about royal purple from people that have used it in other cars.

 

Royal purple is a very good oil, its still a semi synthetic though.
If you wanted to go full synthetic get amzoil or redline oil.

 

Don't get any oil filters from chain parts stores. Make sure you go to Audi for one or they will give you the smaller outdated one that is known for helping sludge.

 

Yea I ended up caving and just going to Stealerville. The damage wasn't as bad as I expected from a dealer. $13 for the Audi filter, $0.65 for the drain plug crush washer, and for 5qts of Mobil1 $47. Still better than ~$110 they wanted to charge me for them to do it.

 

wow u got robbed man. wait till autozone or advanced has synthetic oil specials and then buy like 3 oil changes. u'll pay about 40 bux for oil and filter.

 

Oh I know that the dealership killed me but when I looked at advance, they were selling the oil at $8.90/qt. So yes, I paid more but w/e so I spent an extra $10 here but overall saved myself like $50 for someone else to do it...

 

haha i think u spent mroe than an extra 10 bux but o well u'll kno next time. so have u done it already? how does it feel the first time? lol i remember being really excited and extremely happy the first time i ever changed the oil on a car. it was like ahhh im not an oil changing virgin anymore lol

 

Haha, yea I got it changed this afternoon. Made me pretty happy I'd say. I've changed the oil on my truck several times and on my old 914 a few too, so I wasn't an oil changing virgin but on the Audi yes. lol

I guess I'll wait and find out when advance has a good sale on a few quarts of oil so I can be ready for the next few changes.
