LSJR on oil consumption

Thread 'LSJR blends up a custom oil in the lab'

Sep 6, 2025

I found the blending of a custom oil very interesting. Lake does this in HPL’s lab. He touches on a bunch of amazing information regarding custom blends(boutique) vs cookie cutter(pre approved) and various ingredient advantages. I definitely learned a couple things. A little spoiler MPAO,PAO/AN/Ester….

Almost. MPAO/PAO/AN/Ester

Should I expect higher oil consumption if I downshift a lot?

I would say no......if anything you are putting more vacuum on the rings=good

The way my MK7 VW ea888.3 pcv works is like he described. On idle/throttle closed the pcv gets vacuum via a port in the block to the intake valves. In that situation if oil has been "misplaced" in the pcv from a heavy brake followed by a right turn...when that path opens it sucks the oil in and you get a plume of white smoke. On throttle that port closes and vacuum is generated by the intake.

Maybe I missed it but why would higher grade oil may not be the best viscosity for low tension piston ring applications?

Timely video. My dad just came over for an oil change last night after he's had a low oil light 2x in 6k oci, 2014 Silverado w 122k

We installed Valvoline Restore and protect up a grade in 5W-30 and I ordered him a new PCV valve, so we'll see how it goes. We've consistently used Dexos1 rated synthetics in his truck since new, but it does see severe service.

Good question. Something about putting stress on the control rings and the spring in between. Not sure as many euro engines call for 40 grade and also have low tension rings. My personal experience has been going up in grade helps oil consumption.

And if this is true, wouldnt most low tension ring applications consume oil before normal operating temperature?

Wonder what "W2-40" is View attachment 303349

Dude....I saw that he had some HPL but didn't see the label...

Left a comment on the video about it...we'll see if he responds...

See his recent video on his custom blend oil. He blends his own oil in the HPL lab.

Quite a few European vehicles where 40 was once recommended, now call for a lower viscosity. Maybe Co2 isn't the only reason.

Such as what?

I would ask Lake that question. My comment wasn't one made from a position of stating a fact.

Maybe we can get LSJR to have a Q&A post here on BITOG

Always these same type of useless passive aggressive questions instead of being straightforward.

Detonation > dirty rings > less scraping > oil consumption.

Yes I understand that some people get triggered when asked to explain what they themselves post.

Others in the same thread apparently.

Are you sure there is detonation? And this results in dirty rings?

I am summarizing what LSJ said.

Yeah. Hmm.
