Viscosity debate....

[Joe Papa Sr]

Thanks, Dave. Yup, And there are more of these products out there yet, many of which contain no more than paint thinner.....MMO, among others......very few though, can hide their ingredients from me, so far........

To change subject, but related, I find the same situation in the HUGE cosmetics industry products, household cleaners/disinfectants, etc. They even fool my wife/kids with their invasive/powerfully convincing ads.......

Our economy could almost come to a halt, should these products suddenly disappear from the stores tomorrow........LOLOLOL!!!

obviously no further discussion necessary. We've heard it from the experts. Thread closed.

Thanks Dave, good stuff. What I basically got out of David Navones' comments was to add the ZDDP unless your driving your car like a Grandma, never reving over 3600 RPM. I don't know about the rest of you but my Alfa really comes alive at 4000 and higher. I also noted he stated that high performance engines with higher spring pressure will also benifit from added ZDDP, so my Ford 428 hot rod will benifit as well, especially during the initial engine break in period. But the best point that was made there's no need to add ZDDP to stock engines past break in period in non-race applications. But from my point of view, every time I wrap that high reving little Alfa up to 5500 and run through the gears like that it sure can't hurt to have that little extra ZDDP in the oil. To each his own, a 6 dollar can of BG-MOA at each oil change is not going to hurt anything and if you like to really "drive" your sports car, its a good idea.

ZddPlus - ZDDP Oil Additive for Classic Cars

Read the material on the subject, and placed order for a 3-pack. I've got high performance valve springs, and a motor that flies to 6500 RPM in a heartbeat, with more top end still available.

That's a bunch of lbs of pressure lifting and closing the valve.

GM's EOS is priced too high. ZDDPplus is priced at what EOS used to be.

Everybody makes and lives with their choices. A bit of ZDDP as an additive seems good insurance to those with higher performance, flat tappet engines, running at higher revs.

This just occured to me. Don't the flat tappets in our beloved Alfa Nords live in troughs filled with oil and almost never ever loose lubrication?

Just a thought.

That's true in the Alfa V6 as well, Dave, but it still doesn't stop 'em from a tendency to eat camshafts. Even in an oil bath the oil film between parts can still break down, at which point it's the ZDDP-modified surface layer that protects the metal.

Not that I'm using additives, but in the absence of additional data I still think it's wise to use an oil with enough ZDDP in these engines. Both Mobil and Syntec appear to have recently re-increased ZDDP levels in at least some of their oils (after lowering them down for a while) which tells me there's something going on here.

Neither you nor I have the full story or the complete data. I prefer to err on the safe side, however, and Mobil1 15W50 (with 1200ppm) is easy enough to find.

Plus, according to some we don't have to worry because of the OHC design. It's only an issue with the extra pressure resulting from the strong springs multiplied by the ratio of the rockers on an OHV design engine. I think you just have to decide for yourself based on ?????? and go with it.

Hey Joe,

We all know that the big oil refiners supressed carburator inventions that could have delivered hundreds of mpg.

And you know that carefully formulated and blended engine oils, can always be improved by buying additives, just like the improved performance you get adding things to your tank of gas.

And I will have you know that my wife uses a skin cream (actually several) that reduce the "appearance" of wrinkles by more than 28% and that has ben clinically proven. She also "builds" bone mass and therefore avoids osteoporosis by taking a single pill every month...

Heck Joe you know the old saying..."Old Chemists never die, they just fail to react"..

TTFN and LOL as he busies himself in the cellar looking after an acetobacter culture to make more of his much sought after Wine Vinegar!

Ciao Giuseppe, hot up here 87 today!

I wish you and your wife continued good health, Elio, old friend, and if pills help, the better. I take a pill here and there too.

But my low pill consumption from my kind is not what makes the pharmaceutical companies happy with the big dollars. If I keep watching my body, like my car, not abusing it, there should be little need for designer drugs/elixirs to heal the damage done.

Heard they closed schools in CT today, cuz it hit about 98 deg F, and they didnt have air conditioners....they should come to FL.....LOL!

[Joe Papa Sr]

Maybe a hijack, but....dont be fooled. The pharmaceuticals have the biggest profit as an industry (around 15-18%), now that banks have collapsed (they were second before). They feed/prey on us consumers with powerful ads. We feed into it with our "magic pill/want it cured now" mentality. Powerful lobbyists in D.C., along with Insurance, guns, and Big Coal.

Watch for that so called "clinically proven" claim (s). Jimmying statistics/numbers to cloak the results they truly desire. Us US taxpayers fund their research, then they cry [we need big profits cuz research is expensive], crying, boo hooooo.

Ahem, back to zinc......LOL!!
