Taking over the changes on my girls convertible and wanted to ask everyone here what they suggest. Reason being she is paying $100 or thereabouts at the local mechanic for a change with full syn.

2005 Audi A4 1.8t 105k miles

Going to do Full Synthetic, and preferably 10k changes. Oil has been changed every 10k with syn.

I have checked the oil on numerous occasions and the engine consumes about 1qt-1.5 qts per Oil change interval, after about 7000 miles it will start consuming. On these occasions I used a 5w-40 for makeup oil. The oil also gets significantly black in this car around the 7k mark.

What viscosity and brand do you think I should be looking at? No leaks at all.

Thanks for all the help.

JC

Mobil 1 0w40 European formula, at walmart its $22-25 per 5.1 quart jug. It should only take 4.3 quarts so you have some left for top off. No other oil is such a good value.


Mobil 1 0W-40 synthetic motor oil meets or exceeds the requirements of:
API SN/SM/SL/SJ
ACEA A3/B3, A3/B4
Nissan GT-R

Mobil 1 0W-40 motor oil has the following builders approval:
MB-Approval 229.3
MB-Approval 229.5
BMW LONGLIFE OIL 01
VW 502 00
VW 505 00
PORSCHE A40

According to ExxonMobil, Mobil 1 0W-40 is of the following quality:

100$ is not bad at all for a mechanic to change it. But anyway I'm pretty sure that car specs some type and weight that is not your everyday oil so I would consult the manual before dumping any old stuff in there.

The engine speciies a VW 502 00 oil, so M1 0w40 is good to go. You can also use a 5w30 or 5w40 if it meets this spec, but the high VI M1 0w40 is pretty hard to beat.

Your oil choice is easy, your filter choice should be more prudent. I would go with a Mahle or Mann.

M1 0w-40, Rotella T6, Castrol Edge 0w-30 or 0w-40; take your pick.

10,000 miles is pretty long for this motor. Check for sludge and consider a UOA if you're running it that long.

The Mahle or Mann filter recommendation is good.

Since your are changing it, bump the OCI down to 7.5K and change with Mobil 1 0W40 with a Fram Ultra changed every other change.

Be careful about what oil filter you use.

Audi changed the oil filter specification after you car was manufactured, to an oversized filter. Some sources will try to see you the older spec filter.

Any good quality filter will work. However, be careful about what filter you purchase because some are difficult to remove:
- Baldwin filters do not have flutes
- Mann W940/25 filters require a special tool

I have been using 5K OCIs, with no signs of coking or sludge.

As mentioned above, stick with European spec oils that meet VW 502 00 specifications. 5qt jugs of M1 0W50 at Walmart is your best bet. With the new filter spec your car will take 5 qts of oil.

When changing the oil, the filter will dump about a cup of oil. I put a bunch of paper towels under the filter to catch the oil. Some people use a milk jug with the bottom cut out.

There is a pocket in the engine block under the filter that will pool oil. Be sure to clean this out.

Large OD drain plug crush washers may leak.

Moving the coolant recovery tank will make oil filter removal easier. Remove the two screws and it should lift out. Hoses and cables are long enough so you can tilt it toward the front.

I have been using 5K OCIs with no sign of sludge or coking, at 90K miles.

This.

Aren't the 1.8T known for sludge issues? I'd use a quality synthetic and keep it to a 5k mile OCI. Unfortunately it doubles your cost compared to doing a 10k OCI, but the two oil changes still cost less than the $100 it was previously costing for each oil change.

Mobil 1 0w-40 with a Mahle filter. I'd keep it at a 7-8k OCI, though, given that motor's history of coking up.

A German built filter is better suited to this type of car, thats what I use in my Mercedes. Oil in the US market does not meet the stringent ACEA standards of Europe, keep your OCI within reason to preserve the longevity of your vehicle.

If you plan to buy Bosch or Audi filters, they are not German built.

Bosch filters are Purolator and Audi filters sold in USA are made by Champion Labs, the last time I checked.

Only the longitudinal 1.8T's have the sludge issues.

transverse 1.8T's (Golf, GTI, Jetta & TT) have a larger crankcase capacity.

Wix 51452 or NAPAgold probably has better performance specs than the German ones.
Wix says theirs is 95% @ 20 microns, and German Mahle, Mann, Hengst keep it a secret.
I'd use the Wix since they're a solid choice, publish performance info, and use synthetic fibers mixed into their cellulose fibers.

Oil in the U.S. doesn't meet ACEA standards? Wrong. (I will not say anything snarky about this, but I really want to right now.)

Really?

.... so Mobil 1 0w40 does not meet the stringent ACEA standards of Europe?

so, Mobil 0w40 does not meet ACEA A3/B3 & ACEA A3/B4?

News to me.

I guess Shell is lying about the Rotella T6 also... since according to you, it does not meet ACEA standards.

Maybe Mobil oil is lying about its Mobil 1 Turbo Diesel Truck meeting the stringent ACEA E7 issue 2 standards.

though for filters.... I'd just buy a 10-pack of the Mann oil filter.
