So as I wrote in a previous post I had on my tired 2F some strange knocking appear, disappear, reappear...
A couple of months ago it happened again in front of a O'Reilly's auto-parts store.
A farmer just came in the lot and heard the knock. He approached me and suggested I use Marvel Mystery Oil (MMO). He has been using it on his equipment, diesel and all and it had done wonders. All the way back to his grandfather they had with success used it, he claimed. He swore by it.
I asked him if he's a stockholder or MMO sales person, he laughed. I explained him my reservations about all things "additives" and how my Dad used to say "They all work.... ...in creating revenue for the seller.."
But this guy claimed this stuff does work suggesting to give it a try. What you have to loose at the cost of a beer or two in a pub?
True.
So I changed the oil and replaced as per MMO label 20% with their stuff.
And I drove.
Surprisingly, my old chattering engine gradually started to run a little smoother and quieter. those random hard knocks didn't come back and she definitely got stronger.
3,000 miles later I did an oil change. Out came everything less actual engine parts. The oil had a strange shimmer to it when stirred (see pic). At the end emptying the drain collection pan came little black chunks up ti 1/8" in size.
I suspended a strong little neodymium (rare earth) magnet on the oil surface but whatever was suspended in the oil appeared to be not magnetic (iron). (Good....!)
Those little black chunks where kind of hard but you could squish them and rub then to some black smear. (Dump pan closeup pic)
So I wonder, does it really work? Is this all the muck and carbon getting dislodged and washed out?
I'm fresh with 80% oil, 20% MMOl and a filter and so far I' added 500 miles since the oil change and must say she runs really well, stronger and relatively quieter than ever (Doesn't like to be rev'd over 3,000) considering age and all.
Hmmm?
Marvel Mystery? Maybe well so. It seems to do something good!
