Zinc additive

I know we've had many discussions about what oils we use and some guys have brought up the fact that Zinc has been reduced or removed from current oils. Came across this in my Muscle Car Review magazine. Don't know about cost but thought some of you might be interested...

the newer automotive oils that have been coming out will cause all kinds of problems that we in the business have not experianced before it is really hard on valve trains and seals actually dry out and will shrink and harden when exposed to it for any lentgh of time. it seems as if the multi grade oils will cause cam lobes to get wiped out and is hard on plain bearings as well on higher rpm and higher stressed engines. about three months ago there was a huge disscusion on this forum about oil's and i don't want to get involved with that again so all i'm going to say is for the price of good quality oils and how much engine repairs can be i would use the best quality motorcycle specific oils i could buy. i have started using straight 50 weight oils in my big drag bike for this reason, also when your putting together an engine it is wise to use proper assembly lube on the cams and bearing surfaces i have always used torco mpz assembly lube and i have never lost a cam because of it web cams also ship small packs of torco with there new cams so if it is good enough for them then i know i have been using the right stuff all along.

Brad Penn, is that Brad Pitt's cousin?

Can somebody fluent in English please translate? Is their product any better than their language skills?

they are talking about the oil jug itself it has a notch cut into it to make it more or less spillproof so you wont need a funnel it is a nice touch.and the oil is quite good a lot of the best car drag racers are using it.

Chevron Delo Diesel 15w-40 still has more than enough zddp in it.Just use it. Lol. I still have about 7 quarts of the Brad Penn 20w-50 sitting around (pre motorcycle version). It foams like crazy... By the way, there's some UOA's over at BITOG on the Brad Penn stuff, it really doesn't contain that much zddp. Who knows though, formulations are constantly changing. Good luck and use the Delo unless you want to go motorcycle specific

The bottle of STP 4-cylinder oil treatment I have says on the label it contains ZDDP (zinc) additives. I checked the MSDS sheet and it says in contains 1 - 5% zinc additives:

whatsinproducts.com/information.php?bran...ac25f59fe730c340b34d

Since the bottle is 15 ounces added to about 4 quarts (128 ounces) of oil, the dilution is about 12%. Assuming about 2% zinc in the product, then diluting by 12%, that leaves a zinc concentration of about 0.24 percent which is about 2400 ppm (parts per million) as far as I can figure. That's just about optimal for engine protection from what I have read. Oils used to run about 1500 - 2000 ppm zinc until they phased it out to protect the catalytic converters.

delo and rotella were reccomended by the guy who did my machine work...diesel service oils that he said had additives others dont....i would think zddp is one of them.....i just changed mine after putting 350 miles
on motor after piston/top end rebuild and i put in two qts rotella and the rest valvoline bike oil....just my .02......keith

"A unique cut off our tower . . ." We're supposed to believe that this oil comes off of their cracking tower as a distinct product.
"Penn Grade Crude . . ." Oil was first discovered on this continent in Pennsylvania. They were the first, They was the best... yada yada yada.
Brad Penn, is that Brad Pitt's cousin? Not too sure about anybody named Penn but I do know a certain Pitt who's swimming needs to improve!

:laugh:

The Brad Penn Oil is the old Kendal Formula this is the same oil most reccomended by crank builders and cam manufactures. When you have direct cam to followerr contact this oil has proved hard to beat for many years now. You can use it with confidence as a proven formulation.

Good stuff Marty.

That oil and the Joe Gibbs brand are the two I tell my customers to use for break in.

Here's an interesting tid bit on oil that will likely get some ooooos and aaaaaahhhhhs from some people.

Guy I know dyno's a lot of race engines on a weekly basis. He's found absolutely no detriment to using synthetic oils in fresh motors. No ring seal issues at all. This is not a singular event either.

Hey Larry, many people still do not know about the Kendall/Brad Penn/Gibbs oil. all the same stuff and most always reccommended by the crank-camshaft manufactures
