Zinc Oil

[Donny]

Anyone know where I can get some? Need it for my 440, don't want to flatten the cam lobes on modern oil that is suited for roller cams. I've tried AutoZone, they are a big bowl of suck-lots of junk that's overpriced and they don't even have Zinc oil, and, the management has no idea what that means; Zinc Oil! :sleepy1:

OIL containing Phosphorus Zinc Oxide, In my old race engines, I would use Torco Racing Oil products, it's pricey though, I believe they make an additive that contains the Zinc formula, that will work with any of the more commonly available oils, try their website maybe.... Try Summit Racing or Jegs for the cheaper stuff... "I think" Quaker State has an oil that contains Zinc & Castrol High Mileage Oil "might" contain Zinc, Everything I have now is Roller equipped so I don't use the stuff any longer... good luck

I got some from Advance. Made by Lucas Oil (zinc plus break in additive).

Mancini racing sells an oil "Brad Penn motor oil" High Zinc blend content $7.95 a qt. & a new product, "Z-Alt" $8.95 a qt., advertised "Perfect for pre-1975 engines running with Hyd. Flat tappet & Mechanical camshafts pure petroleum based infused with Moly that offers superior protection in older engine designs" I don't know if it's a Zinc based oil or not... also found Lucas Oil, Lunati, Edelbrock, Comp Cams "break in oils" all with High Zinc content and pricey...

Rotella Oil

Shell Oil makes an oil with a bunch of ZINC in it called Rotella which is advertised for Diesel engines. I believe many of the parts houses carry it in stock. The US government outlawed the use of Zinc products in car engine oils 10 years ago but not in diesel engines. I've used Rotella successfully for many years in my older flat tappet style engines. I 've always wondered if the newer synthetic oils would do the same thing on the older engine styles with flats.

I use Brad Penn for their zinc content. I think Valvoline racing oil is good to. Amsoil is also advertising a high zinc oil now.

I have been using Z-Alt oil, mostly a mail order product. They also have a zinc additive available if you don't like their choice of viscosity.

I use Lucas products for a lot of things and they do have stuff for breaking in cams, link below if you want to check it out.

Some use it as just a additive, i mention it again because they make a certain one just for breaking in cams, kind of two different things, the same company... Auto zone should carry it to!

Advance Auto carries 1 qt. bottles of Rislone that has a zinc additive. Just add that qt. in place of 1 qt. of your regular oil.

Valvoline VR-1 is marketed as a race oil and contains a lot of zinc. Shell's been lowering the zinc content of Rotella consistantly for quite some time now and at this point, I'm not sure that there's enough in it to make any difference.

The elimination of zinc has more to do with the auto manufacturers than the govenment. All the government said was that any part of the vehicles emmision control system has to be warranteed for a period of 10 years. Well, when the manufacturers got sick and tired of replacing catalytic converters on every 9-10 year old oil burning piece of **** on the road (zinc kills cats) they petitioned the oil companies to get rid of it. They ARE the single largest purchaser of motor oils and have the clout to make that call and besides, roller cams had been standard equipmeent for years by that time, they didn't need zinc in the first place.

Seriously, scout around for the Valvoline. Sometimes you can get really good deals on cases of it from places like Autozone, Advance or O'Reillys. You can also toss in a bottle of Comp Cams break in additive at every oil change. That's what that stuff is, a zinc additive.

Basically you can run any oil that has an API rating of SL or lower. The stuff now is SM and up and that's no good for our older cars. Even some diesel oil lost it's zinc and phos content. I run SWEPCO, and though is does not have the API rating, it is a heavy duty fleet oil and is made to the SL standard. All I know is I have it in all my older cars and no issues.

I learned about SWEPCO from my Porsche days, and when it comes to finding good oil, the folks with the expensive to rebuild hot running air cooled engines will find it! Excellent oil article here from some Porsche folks.

The Shell Rotella with the CI-4 rating is the oil you want to use while the CJ-4 oils are not.

I have a 8 qt pan. I use 7 qts Valvoline VR1 and 1 QT Lucas Additive with Zinc. It might be over kill but I have never had problems.

Find an auto repair shop in your area that sells BG products. By a can of "MOA"

 

[GetX'd]

I use Lucas oil products as well in my 440 for the high zinc content. I usually buy the jugs from Summit.

 

[Ranger16]

The US government outlawed the use of Zinc products in car engine oils 10 years ago but not in diesel engines.

That is not true. Zinc content has been REDUCED, not outlawed. I know this is old, but since it was resurrected I had to comment. I'm surprised no
one caught or challenged this when it was posted.

Search the web for 540ratblog.com - the guy is a mechanical engineer and has a boat load of information on motor oils and
compares many different brands of oil and talks about zinc additives. It is long but very informative.
