Zinc removed from oil?

[JeremyB]

I was reading about lifter and bearings failing more frequently due to the removal of Zinc and other adatives. This was only after one of my lifters and cam lobe was destroyed in my 460. It has been stated that the issue with the oil arose from effects on the catalitic converter on new vehicles.

SO, I was wondering if this might be something to ponder with these older engines and not being up to the newer vehicles specks?

new oil

I don't like the new oil, or the new diesel fuel

My oil supply is getting low

I wouldn't worry about it. Apparently, the zinc is still there in the new CJ 15w40 oils, just in lesser amounts. I think I recall that new Delo has 1300ppm+ Old Delo CI stuff had 1500ppm+. New Rotella T 15w40 has somewhat less.

Has Zinc Been Removed from Motor Oils?

Also, we had this discussion before. I don't know how to make links from the old site work, but others here do. Can someone fix this link please?

You can do what I do.

I buy Zink pills in the vitamin section of the drugstore. I put 2 in the oil with every oil change!

A healthy engine is a happy engine.


btw, a little Beano helps with excessive blow-by also!

My engine needs Centrum Silver. It is a senior citizen.

to my knowledge rotella still has zinc. it's what we use to break in all freshly rebuilt flat tappet engines.

there are several companies making break in oil now just for this purpose.

they all have it - some just have more. try searching for zddp - it is the zinc addative. there is a lot of info on the net but basicly amsoil and rotella have two of the highest zonc contents available. it gets used up over time, between zinc loss and dilusion by contaminants from blowby you get the most important reasons for changing oil regularly.
