I was informed by firefighter and another pal about the importance of having a zinc additive added to your oil during initial cam break in. I used regular oil on my break in and began to panic so I wanted to get the story....and it is potentially catastrophic! I called Valvoline this morning and spoke to Chris at their tech department and confirmend the story; zinc dithiophosphate (ZnDTP) levels were reduced by mandate of the EPA within the past year. He said regular oils now have less than 850 ppm ZnDTP but their diesel oils are still between 900 and 1000 PPM and their valvoline racing oil has 1300ppm because it's designed for off-road use. OK, so that's the oil part, I then called Engle, the manufacturer of my cam and spoke to Doug. I asked about the low zinc deal and asked if this was really something to worry about, he said YES. In fact he stated emphatically to use an additive not only during break-in but ALL THE TIME. he said the low ZnDTP will eat the cam/lifters and due to shavings floating around the engine...eventually the rest of the motor will go too. So what to do? - Use a Zinc additive. Engle suggests "justice brothers" and figherfighter suggests GM EOS or ZZDP plus - My pal talked to Bullet racing cams (they custom ground his hemi cam) and they say any oil conforming to CI-4 rating (Diesel oil) offers adequate protection - I haven't tried any additive yet so I can't make a recommendation...but feel free to add to this post I can't believe this isn't getting press...or if it has I sure missed it. P.S. my engine is OK  |

Bill, this is what happens when you don't have adequate oil protection additives : http://www.dodgecharger.com/forum/index.php/topic,46002.0.htmlThere are several race oils out there with added zinc/phos (royal purple racing/amsoil etc...) but those cost big $$. A good diesel oil like Rotella T 15/40 with an EP additive will work just as well. The Rotella used to have lots of the good stuff in it but that has now changed thanks to the EPA.  The additives i would use include ; GM Engine oil supplement (EOS), Comp Cams breakin lube, or ZZDP plus. Bill you dodged a bullet brother....don't take anymore chances. Ron |

Thankfully Ron alerted me to this awhile ago and I went around buying up as much Rotella CL-4 as I could get my hands on and I have a stockpile of GM EOS as well. It was good timing as the old Rotella was being replaced with the new lower zinc stuff at the time so I grabbed every one I could find locally. In a few years when my stockpile is used up I'll switch to whatever high zinc racing oil is available and continue using GM EOS.

The valvoline guy said synthetics also conform to the new low lead criteria  |

Does anyone have an update on the oil additive that Mopar Performance was working on?

Just curious, but what if you run synthetic?? Royal Purple "racing" has lots of zinc/phos but it's $12 a quart.  Mobil 1 motorcycle oil also has lots of the good stuff as well  I like dinosaur oil with a little extra kick (EOS/Comp breakin lube or ZZDP plus)  Ron |

I've put 2,000 miles on my rebuilt motor and used Valvoline ZR1 racing oil from day one. It is listed as racing oil because it has the Zinc in it. Please confirm this oil is o.k and I need to do nothing else?

The VR-1 20/50 racing oil is descent but i would still add an EP additive.  Ron |

How can you tell the older better Rotella from the newer stuff? Local gas station has bottles that look like they been sitting for quite some time..so i may buy up a stock if its the older better stuff.

Frank, the old Rotella 15/40 will have a CL-4 or CL-4 plus rating on the bottle. The new "reformulated" Rotella has a different rating and a sunburst logo on the bottle. It's still descent but the zinc/phos has dropped from 1400-1500 ppm down to 900-1000. Adding a bottle of the correct EP additive will get it back up to where it used to be if not slightly better.

Alright, I'm lost. So this problem applies to basically all non roller engines? That's a lot of people. And no company's have to make an announcement about this? Seems like they would be setting themselves up for lawsuites from a bunch of vintage car buffs if motors start failing all over the place in the next few years.

Well I'd like to agree but who would we sue? it would have to be the EPA and I'm sure they made like 100 flyers about it and that would leagally cover them. We have to face the fact we are an extreme minority and gov't and 99% of industry doesn't care about us or people who own 20+ Y/O cars |

You're probably right. Funny how things work. Now, if you were talking about some sort of civil rights issue and we were the extreme minority I bet agencies/press would be falling over themselves to make sure everybody knew.

The 4.7 is an overhead cam design. It has roller type cam followers. |
