Oil consumption After Premium Blue Restore

[Four Rings]

Hello all,
Now this is going to seem very stupid but please give me a pass on this one.
TGDI 1.6L with no oil consumption issues prior to treatment has gone through 600ml of PBR and MMO mix (3.78l PBR 113ml MMO mix) in a 1000 km.
Now I know you ask if it had no oil consumption issues prior why would I do this, and in retrospect it seems kind of stupid but I thought I would give my engine a preemptive good clean before I start my new round of tuning with my tuner.
It's not leaking oil anywhere. Is there anyway this could be an expected occurrence because of the nature of the oil or do I need to do a compression and leakdown test.
Thanks for any and all input.
Again I know it was a mistake...

IMHO try PBR again, straight (unadulterated), no MMO.

Give PBR a chance to work. Let it run per label instructions for one-(1) OCI. Top-up as needed. Then switch back to your preferred motor oil.

Premium Blue Restore.

I thought it might be. I call it VPBR.
I'm running a 20% mix of it in three of my vehicles. No issue.

I've been running 1 qt of VPBR mixed with 5 qts of M1 Euro in my 2007 GM gasoline 6.2L (w/197k miles) for the last 6k miles. I dropped the oil pan last week to see if it doing any cleaning. It is.

I must be dumb, did OP mean to say "It's now leaking oil everywhere"?

Okay, I give up, what is PBR????????

Now available in the convenient 99 pack!

Sorry to derail. What oil and OCI were you running before cleaning?

 

[loneryder]

Thought MMO was light & boil-off prone? I've never been crazy enough to use it, except as a diesel fuel additive.

Maybe that's the consumption he noticed.

Okay so my cylinder compression in one cylinder is slowly leaking down on a compression test. I don't have a leak down tester currently but I'm wondering if I add a teaspoon of oil will this help me diagnose whether it's the rings or not with a compression tester or will the pressure still slowly drop even if it's a wet test?

 

[fbdewar]

PP Euro 0W40 every 3.5k mi

Negative. No external leaks. Cylinder 4 has a leak somewhere

Its a road hard hung up wet used car.

 

[fbdewar]

No idea what this means

Are you saying it’s using oil after you ran that mix or it used the oil while running the mix?

 

[fbdewar]

During the interval. I don't know whether consumption issues remain yet.

Might just be the mmo evaporated then. Hopefully

@fbdewar - where did you plumb the catch can to on the engine?

It might be that you don’t have enough vacuum for turbo oil drain hack and some oil is sucked through the turbo rings and thus the oil losses you experienced,

I reverted back from catch can to (new) PCV on my TGDI and found the original PCV (plumbed in just before the turbo and on inlet between the throttle body and cylinders) have a HUGE amount of vacuum on the sump. When I remove the dipstick on idle and hold my finger on the tube you can feel the high vacuum. My oil consumption seemed to slow but still monitoring, car not driven much at the moment.

Hope you get it resolved.

It's a damond Motorsports kit that is plumbed into the valve cover.
Thank you for your input I very much appreciate it and I'll keep this in mind but I definitely experienced a leak on one of my cylinders during a compression test and can hear air escaping when I put my ear to the oil filler opening. What's strange is that the plug isn't fouled in that cylinder so maybe there are two issues as you are suggesting.

So it sounds like you did a standard cranking compression test. What did the various cylinders read?
The simplest way to find where the cylinder is leaking (Valves, rings or {Shudder} head gasket) is to apply air pressure as in a leak down test and listen at the tailpipe, oil fill and the throttle body. You should be able to readily hear it.
It could be as simple as a bit of carbon stuck under a valve.

MMO burn off would be my guess.

Turns out i was a dummy and my compression tester schrader valve was leaking.
Never figured it out. Oil consumption remains even after switching back to original change.

Thread title would be more accurate as "Oil consumption after hodge podge of DIY juice mix."
