Hi everyone. The PO and unfortunately myself for a period of time used modern oil in the car.

My belief is as a result caused vibrations and it had minor oil usage. I could go through quite a bit if i kept rpm above 5k frequently.

I've used additives to reduce friction in addition to the ZDDP present in my engine oil: Royal Purple HPS 20W50...I've used Hy-Per lube and concentrated ZDDP with positive results so I believe that improvement is possible....

I decided to try the Boron additive (Motor Silk):

I've seen significant reductions in vibrations at all
RPM. Oil consumption even at high rpm so far has also gone away completely.

She's also running cooler. It also revs easier...idles smoother and feels stronger. To me all indications of a successful treatment and application of claims.

I put in two cans (total 32 oz) based on their sizing and our capacity.

Really interested if anyone else has used or considered using this product. It so far has made a very positive difference for my car.

I could imagine the better condition an engine is theoretically the less benefit the product may provide, but the biggest shock to me is what appears to be the complete cessation of all oil consumption...and I could make it go through quite a bit of oil if I really pushed it hard at upper rpm...that seems to no longer be the case.

Anyone else tried it and if yes, did you have similar results?

What exactly does this mean?

ZDDP is only needed in one area = where the lifter meets the camshaft. That's is.

Lack of the proper amount of ZDDP will potentially cause camshaft damage. So unless the running issue can be attributed to pitted camshafts, I don't see how the two are related. If your car suffered any damage due to low levels of ZDDP, no additive will "fix" a damaged camshaft or lifter.

Adding ZDDP additive can actually be counterproductive. Pick an oil with 1100/1200ppm and be done with it (most 15/20w-50's have this amount already).

No comment on the Boron additive, but if it "fixed" your oil usage then it's working for you!

One post:
Makes me wonder if this is similar to people who claim running a bottle of ATF through their engine before an oil change is helpful to break apart and flush out sludge. Maybe that is what's happening with your engine?

Hey Hacker...modern oil meaning one without the elevated levels of ZDDP our engines use/need. My understanding is that traditional modern oils don't have this level. Once I understood I moved to the Royal Purple HPS which has the additional ZDDP and have used additional additives (Hy-Per Lube) with positive results...being reduction in engine vibrations.

The website did say that in engines that are particularly dirty, the filter could clog and to "bring an extra" which sounds pretty hilarious to me...but whatever.

It's entirely possible it's cleaning the engine...I have never used an aftermarket engine cleaner type of additive...like a flush or whatever...just changed our oil every 5K and made sure it never ran low...I still don't get why it's no longer using oil...that one's a mystery. It definitely is smoother at higher rpms...I agree with you totally...it's working for me and I'm happy with the results.

Thanks for the thoughts.

History lesson......
Pre 2000 oils had on average 1100/1200ppm ZDDP
After 2000 with the GL-4 oil standard, this level fell to 800/600ppm
After much complaining from the classic car world, most if not all "thicker" oils like 15/20w-50 were "restored" to the old level. Including Mobil 1 15w/50. This is going back 6-7 years or more.
If you look, you can usually find the ZDDP level in whatever oil you are using. Pick one with the "old" level and you'll be fine.

Again, the only place where Zinc (Z in ZDDP) is needed is the high pressure area between the camshaft & lifter since these are flat tappet lifters. No other part of the engine benefits from ZDDP. Any vibration caused by lifter / camshaft damage will not be fixed by any additive. So whatever the vibration is/was is irrelevant to lower ZDDP levels in whatever "modern" oil was used before. But, as explained above, unless you specify exactly what other oil was used, you are only guessing it was low in ZDDP to begin with.

That is very possible and I had it happen in a car years ago (non Porsche). Ran an oil "cleaner" through the crankcase, about 1,000 miles later the oil light started to flash. Drained the oil, pulled the filter and it was heavily clogged. I had already put over 50k miles on this car with no issues. I checked the rod bearings, they were showing wear so I popped in a new set, never ran the cleaning agent through anymore and drove it another 50k miles. It's still running fine, just retired and I should sell it.
