Preliminary results of B12 Piston Soaking for oil consumption reduction

[Theiceman]

Just updating my experience with the B12 soak. When I first got the car, it was doing about a quart every 450 miles. After two soaks, I am now up to 1,500 miles per quart. A nice improvement.

I am going to drive on this change for another 3,000 miles or so then do another soak.

Is this a silver bullet? No. Does it help? Sure seems like it.

which method did you use

put it in rotate the crank periodically .. keep topping it up as it goes through the rings ?

I just poured the stuff in and let it do it's thing. I do think there is something to the rotating the motor in stages so I will probably do that this next time. As discussed, it is all about time with the fluid in the rings. Doing the rotation, top up, exercise will help for sure.

I'm with the sentiment that if you're putting a qt in less than 1K it's going to take a couple soaks to get to a tolerable point. Mine was burning a qt like every 100 miles when I first got it, smoke coming out the back when moving from a dead stop. After the soak the smoke stopped happening but I was still getting consumption, maybe a qt at 300-400 or so. Going to do another soak at the next oil change.

Completely agree.

I don’t agree. I’ve done the soak on close to 10 different vehicles. Most having the 2.0t and a couple with the CREC v6. All had consumption of 1qt per 300-800 miles. After one soak they’ve all gone 2500-5000 miles per qt. Generally speaking this absolutely works.

I definitely agree that works but some cars are worse than others. Some get misfire issues and their plugs are soaked with oil. Like I said mine was burning about a qt every 150 miles which is at least twice as much consumption than a car consuming a qt every 300 to 800 miles. I can see a 1 and done in that range is possible. Your range of 2500 to 5000 after the soak is quite a large range. The question is, would you do another soak on a car that goes only 2500 before a qt is burned? Would the burning come back sooner than later on one that burns a qt at 2500 miles complared to a car that is now burning a qt at 5000 miles?

Honestly, my theory is this: If I can get to 1 qt every 3K, then I will just do a soak every other oil change. It will effectively be a maintenance item moving forward.

Question. If you could do it all over again, would you still buy a 2.0T? Are people just doing this to get as much as they can out of the car and then fk off from Audi brand, or are there people who would knowingly buy an oil burner with the confidence that a simple piston soak would give the car a new life (another 70-100k)?

Most didn’t search out an oil burner, but inadvertently bought one, this is a cheap “Hail Mary” alternative to the more expensive rebuild alternative…..which is still available if it doesn’t work, so long as the cylinder bores don’t get F’d.

I did enough reading about these cars AND I am confident in my own ability to manage the problems. I don't think it is easy to tell if a car is an oil burner so you are always rolling the dice.

[marshallnoise]

Blackstone came back and the results are minty.

No harm to the engine at all by having Berryman in the crankcase. Read 'em and weep. J/K, just haven't said that in a while.

My wife and I bought a fully loaded up 2018 Audi Q7 with 84,000 miles on the clock knowing the CREC 3.0t was prone to oil rings sticking and consuming oil. I wasn't going to buy but the Q7, but its such a great vehicle, I said I know I can fix it if its using oil. So we bought it, drove it 400 miles and it sucked down 3/4 quart on the dash right away. So I did the Berryman's B12 piston soak, then did a can of BG EPR in the crankcase along with the can of B12 that had drained thru the pistons after the soak, ran it for 25 minutes, dropped the oil and filled it with 5-30 Valvoline Restore & Protect.

We drove it to the Twin Cities up to my daughters and it drank a 1/4 Qt of oil on the way up in just 40 miles, then it quit using any oil at all after that. We've put 600 miles on it and it has not used another drop of oil since. Many people have reported no oil loss in 5000 mile changes since they fixed their ring sticking oil burners. I suspect ours will not consume any more oil now that the rings are freed up. The cylinders look great with no scoring and if you catch them early enough things should be fine if you keep the rings freed up. I plan to run the Restore & Protect oil for at least 4 oil changes of 5000 miles to clean the pistons and ring lands up, I'll take oil samples to see how the wear metals look, if all looks good, I may just keep running Restore & Protect forever. It sure runs smooth and powerful now!

[WHT13AR]

Didnt soak but tracking oil consumption...

2013, 127k, no usage after 1700 miles, Castrol 5W40 EU blend.

2015, 143k, 1/2 qt after 2000 miles. Same oil as above. Its a K04 hot rod and I drive it more spirited than not. Im going to try the BG109 restore on this car.

[Veedubber12]

I wonder if anyone here has tried pouring b12 in while the engine is still hot. I imagine it'll just fizz up and evaporate some if done right after you park the car. Thinking about giving it a try while the engine is at least still warm to hot. Maybe about 45 minutes after parking.

I literally did this a week ago. Yeah, the stuff just evaporates immediately.

I decided to give it a try today too and the small amount I poured in immediately fizzed and evaporated. 45 minutes was enough time to where it wouldn't fizz anymore.

[A4Qwattro]

If you don't have any oil consumption, wouldn't it be a good idea to try the Valvoline Restore and Protect as a preventative measure?

Thanks for asking as I'm wondering the same thing. I got my car from my brother in-law and the thing only has 33K on it. I'd love for this thing to last a long time before anything of this significance rears it's head.

Thanks to all for contributing to this thread. Seeing many of you have positive results does help, a bit, to settle the fear of this happening to mine.

My advice is to run the car hard and stay on top of maintenance. Change the oil every 5K and you should be golden.

[Quattrological]

Then I am on the right path/regimen. :)

Thanks for the input!

Realizing now this thread is almost a year old, wow. For those wondering, I'm now at like 30k km post soak, haven't done it again, and haven't burned any oil since (as in literally none).

disappointing news indeed . if you rebuild definitely post pics. silver TT is running the Cummings test as we speak . juryvstill.out

UPDATE on using the Cummins Valvoline Restore for 4.2K miles (I will run it for 5K total) with several double doses of Techron Complete Fuel System Cleaner (contains PEA).* It does NOT appear to have materially changed oil consumption.

That is disappointing to hear. What is the expected mileage at which point Cummins says there should be improvement in diesel engines?

[A4Qwattro]

As a side note, the specification of the Valvoline Restore and Protect seems somewhat mediocre compared to Mobil 1 Euro, Motul Excess, Ravenol VST VollSynth, and the Liquimoly Leichtlauf. The R&P 5W-30 is like water compared to Valvoline's own 5W-30 Euro synthetic product which has the VW approval. R&P viscosities are a bit down compared to the better oils. It seems like a ****tty oil to have to consider running for 4 oil changes as recommend or permanently as some might have wanted to do. Going by Valvoline Euro Synthetic NOACK of up to 15%, I doubt the R&P is any better.

[silver_tt]

I don't know what Cummins says but when I spoke with Lake Speed Jr he told me it should work in 3000-5000 miles but I am 4200 miles in and see no difference.

I was using the Cummins product not the Restore and Protect but I agree the R&P is not one I would be interested in running since it needs multiple OCIs as you say. I'm going to just re-piston the engine ...

I did it with engine at operating temp after a 10 minute drive to oil change location.

Upon arrival my car had liquimoly 30w about 3k miles on it after repairing pcv with confirmed major coolant mix in oil pre-repair.

I added 1 can of BG EPR (half dose than recommended for 7.2Qt) plus full strength dose of seafoam and followed the BG EPR rev instructions for the recommended time and drained the oil from bottom drain plug.

NEXT, I just chickened out on doing piston soak and had already bought the barryman can along with seafoam so i used it as a crankcase 'flush' my logic is that there could still be contamination and 30w oil in there.

I had about 2.5QT left in a 5Qt of liquimoly lechtlauf 40w that was in my garage a year old so i mixed it with the barryman's b12 and the seafoam in total had about 4QT now. with the drainplug recorked, put it into the crankcase and could see a bit evaporating into the heat but not too severe.

I DID NOT RUN THE ENGINE AT ALL.

drainplug removed to let it out, and put in a full dose of clean liquimoly leichtlauf 40w.


TD;DR : If you insist on putting barryman b12 in crankcase you should mix it into some oil to protect it from evaporating

have feeling those rings are going to be like mine when they come out ... carbon as hard as concrete in the scraper rings..

Has anyone considered going on a regular schedule of BG EPR cleaner with each oil change as a preventative measure? I think I am going to try this.

piston soak aint helping that lol...

[silver_tt]

agree... piston soak isn't going to help that and even if it does, these rings are just going to have the same problem again in time. The only permanent solution to this problem on this engine is to re-piston it, everything else is just a temporary Band-Aid.
