i bought a audi the other week it is the a4 quatrro with 2.8 and 5 speed i was going thought the service manul and seen that it was asking oil change every 7,500 to 10,000 if this is true what kind of oil is the facory want you to use and if this is not good what kind of oil should i use and i'll stick with the every 3000 miles.

 

You can change the oil every 10K mi. with one of these:

A good synthetic Oil, depending on conditions, paired with a good filter can last 15k. If you're changing oil every 3k you're wasting your time and money.

true but you gotta also look at the way you drive, i drive the s!it out of my car usually hitting 100mph plus on the country road, this causes conventional oil to break down very fast so for me 2500-3000 is good, even with synthetic oil

 

Thats why I said depending on conditions. For long trips and when proper procedures are used to heat the oil up to temp then it can last a long time. Good for you if you drive the crap out of youre car. You can still do that and have a nice long OCI as long as you warm the oil up to the proper temp. The added fuel during engine warm up leads to oil breakdown.

 

thanks i bought castrol high mileage just making sure there was no special oil to buy and i'm using the extended preformance mobol 1 filter.

 

If you just got your audi I would stick with the 3k oil change for the first 2-3. Just to get ride of the sludge the previous owner caused by using cheap/normal oil.

 

That method won't do a whole lot. Engine oil is for lubrication, not cleaning. If you want to clean your engine out try AutoRX. I've used it and it seems to have helped a bit. The oil filters from my clean and rinse phases were nasty.

 

i dont care if its eccessive i do mine every 3 to 4k.

 

I try to change my 98.5 around 3-4k too. Its more of a "high mileage" thing - just being safe
