Liqui Moly Oil Saver

[VroomTT]

Curious if anyone has in experience with this stuff on our v8's?

Description does almost sound too good to be true, but I'm curious about reduction in consumption lol

I don't think an oil additive can "fix" scored cylinder walls ,
but it might help for a minor , hard to reach , external oil leak( seeping rear main seal for example)

Agreed, not going to fix the problem. I'm just curious if it might help with the amount of consumption.

"Reduces oil consumption via the piston rings and valve guides" is the phrase that caught my eye. Consumption could be due to leaky valve seals, and if this helps with those, than it could reduce the consumption to more acceptable levels...

I know it's wishful thinking, but I'm hoping someone has actual experience with it on our engines. If not, I don't mind being a guinea pig on this one as long as there aren't some known potential negative effects from using this specifically with our 4.2 v8's

Man, give it a shot and document the results. I'm curious to see the results as well.

You could run Liqui Moly Top Tech 4100 which it has additives to help the with the burning of the oil. I'm gonna order me some or my RS4 and see if that helps.

I just swapped my PCV back to the oem one (I had put in a replacement when I did my IM spacers since I was already there, but I think it's a cheapo crap one) and want to see if that makes a difference. I'll give it 300 miles then check the level to see if it made a difference. After that reading I'll try the oil saver and see if it helps. Trying one item at a time to track accurately.

I'm just hesitant to try it since I hear it's pretty thick stuff and I want to be sure there won't be adverse effects on all the small oil passages. Hoping someone can comment on that, then I'll try it and report back.

I'd say give it a shot, LiquiMoly makes good products.

Plus, given that they're a German company and I'm sure that they designed any of their additives with to be compatible with the requirements of German engines.

I use Schaeffer moly lube in all of my vehicles. I buy it in the 5 gallon bucket for right at 300.00 a bucket and add some at each oil change. All I can say is I've had 2 vehicles with over 400k on the odometer and all of my other cars have gotten of 200k. Never had an engine fail due to engine malfunction. Only issues I've ever had were coolant system parts failing. My 2012 chevy sonic has 197000 miles and running strong.

i've done the PCV, suction jet, IM gaskets, Kreen treatment, etc., and all that's changed is that i have come to accept that my oil consumption isn't going away cheaply. even if an additive worked, how long might it last? would it be cheaper to keep using that additive, or to just keep adding oil?

I tried to post about my oil consumption just now, my thread vanished... Anyway, I have a B6S4 with 150k miles on the clock, I have put a LOT of money into it the last 10k miles, I had a mild oil consumption problem last year that just became a "drinking" problem, my car is addicted. It is going through a quart of oil over 250 miles with hard driving. Sucks for me because 10k miles ago I did chains, guides, cam adjusters, engine and trans mounts by 034, FI exhaust, clutch, brakes, tires, all suspension... And now this oil drinking situation is out of control. My car is worth shit probably, I don't know if sell it cheap or find a used block or throw in a 2.7t engine in it. I am very upset, it went from 1 quart every 1500 miles to 1 quart every 1000 miles to 1 quart ever 200-250 miles.

Oh, and to reply to your question, I have tried LM oil saver, lucas oil stabilizer and heavy weight oil such as liqui-moly 10w-60... nothing has helped the oil consumption, though most of my chain rattles went away when I added the oil stabilizer when my problems started, the rattles went away for about a year.

[VroomTT]

So, just as a quick update. My change to an OEM PCV seems to have helped with my consumption quite a bit. Still have not put on that many miles, but I checked the level at 130 miles since pcv change and top off and it's right at the full line, pretty much zero change.

Fingers crossed! Once I hit the 300 mark(which is when I always check oil level), I'll check again and report back. Likely will try the liqui moly after and measure consumption again.

When you say suction jets, what are you referring to? The check-valves and oil jet in the valley? Or something else?

This seems like a drastic and rapid increase. Have you done compression or scoped the cylinders since the consumption increased?

there's a small "suction jet pump" in the PCV/oil filter area that, if i recall, is part of the brake booster vacuum system. the idea was that instead of piston blow-by there's some malfunction in the vacuum system would cause the car to mis-measure crankcase pressure, triggering constant crankcase vapor recirculation, leading to excessive oil being burned in the cylinders. it's a pretty slim chance, but it's an inexpensive part to replace (common across many VAG cars) so i did it with only slight hope it would do anything.

i'm going to do the upper oil check valves and valley pan gasket soon, partly just because i have an oil leak around there - leading to even more oil consumption! i already go through a quart per 1000 miles, and with this leak it's up to a quart per 500 miles (or faster).

My S/4 currently has 105K and I've been using it since the car had 35k on her.
My car does not burn any oil and still has the same timing components.
I've used Swepco oil improver which has moly in it since...
No issues.

Ohh, gotcha. Any chance you could provide a part # for that or point us to it?

sure, it's 058-133-753-D, aka "suction pump", "vacuum suction pump", "purge valve", etc. again, i didn't have much faith that it would fix anything and it didn't seem to, but if you're looking to refresh your vacuum system it's a cheap part ($15-25, or $35-45 OEM).
