View Full Version : How often does oil need to be changed with the 1.8T?

I've been doing a little research before I buy an A4 1.8T and I was wondering... Is changing the oil every 3000 with Mobil 1 good enough, even when you've upgraded the turbo to a GT2871R and like to play with boost every now and then? Thanks.

Yes, as long as your doing fully synthetic.

Have you seafoamed it lately?

I do mine around the 5000 mile mark. I think that people nowadays are obsessed with changing their oil way to often.

5k being the max with me also, and I use full synthetic. If using a group III, I would say change it around the 3k mark. Just an opinion.

I usually change it ever 3-5k miles - I'm using german castrol.

yup. most people (not the op) cling to the one car maintenance item that they will actually do and do it way to often thinking that it is ok to skip the rest. did you get your alignment done, wind shield wipers replaced, replace that burned out headlight, check your tires, or scan for that CEL, nope but i do change my oil every 15 minutes.


i do mobil 1 around 5k not to exceed 5500.

I've got a GT2871R A4 1.8T. I change it every 3-4.5k miles. I used Mobil one for a while, but now use 5W-40 Royal Purp. 5k should not be a problem, but I would recommend changing it around the 3.5k mark if you redline/full boost every time you drive.

Knowing the sludge issues with the 1.8t's i never push it past 3000 miles, using the oil and filter from the dealer.

great, thanks for the awesome responses guys. i think i'll probably stick with doing it every 4500 miles, since i do like stepping into the gas every now and then (but not everytime i drive). i just want to avoid having to deal with engine sludge is all.

Yes, as long as your doing fully synthetic.

Have you seafoamed it lately?
i haven't picked up my B5 yet, but since you brought up the seafoam thing, that got me wondering... could seafoam actually clean up engine sludge? i never thought of seafoam being a sludge remover, but maybe it could be?

I go 5k as well, make sure youre going with the large filter as well. I took the valve cover off and at 135k of 5k intervals everything in the head is still shiny aluminum! Much better than the yellowed sludged up heads Ive seen on some at work who arent as anal with the intervals. 5k is also easy to remember if you start on a 5 or 10k mark, ie 20k, then 25 then 30 etc.

i was thinking today, i use the oversized oil filter, and i go about 5k but more importantly look at your oil when you change it, if it is black as all get out, you should adjust your oci if it is still pretty clear/clean, you could have gone longer. my oil is just a little over slightly dark but never BLACK and i inspect my cams and such to make sure they are not discoloured and that i am not getting any build up.

I dont think color is always a great indicator, the colors of the new oil about to be poured in varies so much I wonder if they change or accumulate differently. If worried send it to Blackstone labs. They do a pretty thorough job.

i change around every 4 weeks, o wait thats because my turbo chugs my oil.

I'm running a GT28RS using synthetic 5W/40 and I change the oil every 3,000 - 5,000 kms which is around 2,000 - 3,000 miles. As soon as it starts getting dark it is changed out and I always use the OEM large filter VW part number 068 115 561 B which is actually the diesel oil filter first used on the 1977 Rabbit/Golf diesel. Do not use Fram, what ever you have been told about these filters is wrong unless you were told they were crap. VW motors do not have internal pressure relief valves so they are in the filter but if you look inside a Fram filter you will not see one. If you use any filter other than the factory ones this is the first thing you should look for, if it doesn't have a pressure relief valve then keep looking. These motors don't really hold a lot of oil so the oil that is in there has to work harder especially with a turbo so it needs to be changed more frequently that is advertised by the factory. I don't risk my motor and because it is pushing out almost double than when it came from the factory it must be properly maintained. This goes the same for the timing belt, mine goes about 1/2 of what the recommended time is just to be safe. The more power the motor makes the easier things wear and/or break so the sooner maintenance is needed.

This sounds like overkill... I recommend ever 5k (miles), 3k if you have a fat wallet and time to kill.

OEM german filters are rated for 20,000 kM and so are most oils. Most Europeans change oil once a year/20k kM.

For the 1.8T, since it is praised as a sludge capable motor, 5k is fine, I do 5k since oil is so cheap in the USA. The oil that comes out is still good based on lab testing. I can also monitor the oil pressure in my car and have replace the oil pickup once.

Stick with 5k synthetic.

so it sounds like changing every 5k is fine, as long as you take off the valve covers and see if there's any sludge build up?

but now what i'm curious about is the oversized oil filter. does anyone know of a good website that sells this oversized oil filter (as corrado guy brought up, the 068 115 561 B)? mjmautohaus has MAHLE oil filters like this one: http://www.mjmautohaus.com/catalog/product_info.php?cPath=6169_6170_6186_6188_6726_92 09&info=Mahle_068115561B.5_Oil_Filters_Pack_of_5_OEM&products_id=2976
i'm not sure if the MAHLE filter is oversized?

With the costs of a good synthetic being what they are there's no freaking way I'm changing it out after only 3,000 miles. On the other end of the spectrum theres also no freaking way I'm leaving it in there until 7-10k like some of the dealers will tell you. I go 5k with an OEM LARGE filter and Lubro Molly 5w40. On a side note for those of you who seafoam. I'm assuming you dump it in (How much? Half bottle?) let the car warm up (not driving it) and then do the change, correct? At what frequency are you performing this maintenance?

I usually wait for Mobil 1 to go on sale at AutoZone or Advance Auto parts. They usually sell 5 qts of Mobil 1 and a Mobil 1 filter for less than $30. I use the M1-301 "Extended Performance" filter. Seems to be a pretty high quality filter, and it is as big as the Mann 940/25 which I use otherwise.

2 minutes jack up car.
1 minute pull the 17mm bolt.
0 minutes wasted draining, unless you sit there and watch it...
1 minute put bolt back in and oil.

Actually, Advance Auto has Castrol Syntec on sale right now. You get 5 qts and a K&N filter (huge 1.8T filter is usually in stock in the K&N brand), all for 26.99.

And Pep Boys has Mobil 1 on sale for $4/qt on Black Friday.
