So last couple months I've been facing this problem where I've been driving and received a low oil warning "minimum oil level, top off 1 quart". Both times have been after around few weeks to a month after the last oil change which is usually around 1000 miles.

From doing my research seems like it could be valve cover/valve cover gasket? But there are no signs of oil leak anywhere and just got a new oil change (drain/refill) today at the shop which they said my valve cover looked perfect with no leaks. They said I was missing 1.5 quarts since the last oil change with them though which was about 3 weeks.

Where could the oil be going? Everything is running fine and after running/installing the upgraded turbo
I haven't had this issue with oil for the last 10k till recently. I have been noticing smoke occasionally Coming from exhaust tips for a minute or so once I power it off but smells like gasoline mainly, not coolant.! Is there anybody else with this issue especially running upgraded turbo?

Could it be blow by? Extra boost from a bigger turbo and the standard breather set up cant cope? Not really heard of it being an issue on the b58's tho

That's what I was thinking too but I've been running relatively low boost/power compared to others with upgraded turbo and this wasn't an issue with the upgraded turbo before.. Plus 1.5 quarts in a few weeks seems crazy for turbo blowby..

I was actually meaning piston blow by not turbo. Its a fair amount to loose il give you that.

Have you wipped of the pipe going into the throttle body? Check for oil there?

Same if you have a bore scope pop it down and look at the compressor housing for oil.

what sorta miles were covered in that few weeks?

Gotcha, that makes more sense lol. I haven't done any of that but the mechanic did a visual inspection of the engine bay and didn't see anything abnormal but I'll definitely get to those when I can.

About 1000 miles I'd say since last oil change before low oil warning came on.

If you think it's piston blowby, might want to get the cylinders compression tested.

Get someone to drive behind as you get on the turbo to see if you are getting smoky-color exhaust gases.
Your new turbo could be eating the oil.

Y'all tagging the wrong guy

Update: Used liqui moly 5W-40 and the problem went away but a month and a half later what do you know, minimum oil warning light again after 2k miles.

Clearly the 5W-40 lasted longer than the 0w-20 by far but the oil is still disappearing somewhere. I'll be running a compression test and leak down test if needed and checking the intake for oil when I can but does anyone have any other insight?

Not sure if my inconsistent weird ticking along with one or two pops from the engine bay one day (never did that sound again) has anything to do with this.

Sleeper340i, what turbocharger did you install?

Aren't you under warranty still? There have been instances where oil sensors have been replaced, but it doesn't sound like that's the problem here.

No smoke while idling correct? PCV issue?

PS What tuning platform and how many miles on the Pure 800? How many lbs of boost, if you don't mind me asking.

Do you get the warning a few weeks after you top it up as well? Or only a few weeks after you get it back from the oil change?

If the first, clearly leaking from somewhere.
If the latter, then maybe they're just not filling it up with the correct amount or to the correct level.
Or filling it to the level on the dipstick, but not topping it up after the engine is run and the oil settles again.

I'm running Pure 800.

Yeah no more warranty and even if I did have it it would be long gone haha.

Car actually smokes a lot when driving these days, I contributed that to the cold weather though and being catless? I just tried leaving it in idle for 10+ minutes and it was smoking white smoke a bit near the end but the smell is not oil smell just smells sweet and like raw fuel.

I'm running Jordan tuned and hitting around 21 PSI on average peak WOT, wasn't able to push it anymore with the 92 octane here hindering me sadly.

I'll be happy if it's a PCV issue or a valve cover gasket compared to something more serious lol. Not looking like I'm getting much symptoms of either above issues tho as car is running pretty solid.

So the first time I got the message the shop actually did a full oil change. The second time I got the warning I did a drain and fill and they said I was missing about 1.5 quarts from what they originally put in. The third time which was the most recent I topped another quart, so we'll see what happens soon just in case some mistake was made as you said.

So i took my car to the shop and they did some testing on the PCV and turns out my PCV is perfectly fine. Next step will be compression testing when i replace my spark plugs since they are somewhat due for change anyways.

Did you figure out what went wrong?

Do you have a oil catch can?

Turned out my engine had failing piston ringlands which was leaking the oil. Eventually got a compression test which found cylinder 3 was 16-20 psi lower than the rest. Ended up getting a new engine from Germany and couldn't be happier with how it performs.

I'd highly recommend getting a compression test if you have any doubts for peace of mind.

Great to hear, although it sucks that it happened. How many miles did your old engine have when the symptoms started showing up?

Awesome! Hoping we get get a good solid 3-5 years with no issues what mods were you running on yours? Also How much was the brand new engine? I got mine with 3000 miles for 4800 including shipping.
