How much oil do you consume?
 

So let's talk oil consumption now that the speeds are getting up there in mileage. Format your responses like this:

Car & Year:
Miles:
How much oil you burn:
Oil weight and type used:
Relevant modifications (PCV, turbo):
Compression (if you have it tested recently):
Source (if known - blowby, turbo, etc.):

Here's mine:

Car & Year: 2008.5 MS3
Miles: 23k
How much oil you burn: 1/2 quart in 3k miles
Oil weight and type used: PP 5w30
Relevant modifications (PCV, turbo, boost): Catch can, inline PCV, stock turbo, 18-19psi
Compression (if you have it tested recently): 185 across the board
Source (if known - blowby, turbo, etc.): Probably parts getting worn. I don't have any oil in the intake from blowby. Daily driven modereatly aggressive (I don't beat the shit out of it)

So no one burns any oil? Or too much to keep track of?

Car & Year: MS3 2008
Miles:52000
How much oil you burn: 1qrt per month
Oil weight and type used: penzoil 5w-40
Relevant modifications (PCV, turbo): Rawr
Compression (if you have it tested recently): n/a
Source (if known - blowby, turbo, etc.): oil in cyl number 1 spark plug hole, leaks prob at oil return line, Blow by on rings. A general cocktail of fail.

How many miles did you drive in 1 month? Out of curiosity, how much oil does the Evo consume?

Car & Year: 2006 MS6
Miles: 70K
How much oil you burn: Very little between changes (3-4K miles)... I swear
Oil weight and type used: 5W-30 Wally Worlds Super Tech Full Synthetic
Relevant modifications (PCV, turbo): None, stock turbo at 18psi
Compression (if you have it tested recently): ??????
Source (if known - blowby, turbo, etc.): Very small traces in intake, throttle body, and turbo piping...

just out of curiosity lex, do you check when the car is cold (like after sitting overnight), or 10-15min right after you shut it down?

If the oil is warm (ie the car has been driven for a while) the oil should settle in the pan pretty quickly so the results should be similar between that and it sitting overnight from what I've seen.

Looks like most aren't burning much. Maybe you guys don't redline the car enough :)

Probably anywhere from 2-3 gallons a year. I go to McDonalds and Taco Bell a lot.

For some reason, after I drive the hell out of it (which is quite often), I can smell burning oil but I never see a change in level and I don't see it anywhere. Car runs great, pulls hard, and no major issues so far.

why 5 40 and not 5 30 like most others?

5w40 is the recommend if you car is burning oil or if your turbo is smoking. Its a thicker oil

One question I do have is how much oil is this beast supposed to hold anyway. I fail at searching and had the people ask the other day. Said the computer called for 6 quarts but it showed full on the stick at 5???

2008 MS3
51,000 miles
less than 1/2 quart per oil change (3500-4000 miles)
Mobil 1 full synthetic 5w30
mods in sig (boost is 19 psi w/ catless dp/rp and tune -- no smoking either)
compression not checked recently, but the car runs like a scalded dog
60-100 mph is 6.1 seconds.

From when I drove my car.

How much oil you burn: very little between 3k oil change intervals, roughly less than 1/4 quart
Oil weight and type used: 5W40 Shell Rotella T6
Relevant modifications (PCV, turbo): OCC, with check-valve, EGR restriction(prob clogged by now). Very little engine mods, 17psi tune
Compression (if you have it tested recently): 180+ all cylinders
Source (if known - blowby, turbo, etc.): Mostly blow-by I'd assume. I did notice more oil in the OCC after track-days.

Relevant mods: OCC with PCV, full bolt-ons minus exhaust mani and turbo
Compression: not sure
Source: I do get some oil in OCC but it's mostly water with some fuel.

I guess I'm the exception here.

Car & Year: 07 Speed3

How much oil you burn: 1qt/1000 miles
Oil weight and type used: Castrol Syntec 5w30 for the most part
Relevant modifications (PCV, turbo): Only intake
Compression (if you have it tested recently): N/A
Source (if known - blowby, turbo, etc.): Turbo I'm guessing? It does smoke but it's awful lot of oil.

Done a compression test?

Not yet. Probably should. Still has engine warranty though so I've thought about bringing it in and letting them deal with it. I would guess they'll immediately go to the turbo replacement though.

So I just changed the Oil and so far it looks like 4 Quarts. came out while 6.1 Quarts when in. I have been monitoring the level by the dip stick but Now I will start check the consumption a little closer.
