Re: [Chrysler300] Zincified oil for a C-300?

Hi Michael & All,<br/><br/>Am sharing a post from the Corvette site that claims that the Valvoline VR1 DOES NOT have any more Zinc than regular street oil but recommends other available Valvoline products. <br/><br/>Short Version here & long version after:<br/><br/>"For those of us who actually want truly elevated levels of zinc in our oil, we have to look no further than Valvoline’s two other Race Oils. They have conventional (petroleum) Racing Oil and Synthetic Racing Oil, both of which truly have elevated levels of zinc."<br/><br/>Tony Rinaldi<br/><br/>Ps, been using Brad Penn but it tends to leak under hard road use. <br/><br/>-------------/-/-<br/>VR1 Racing Oil isn't the oil we thought it was. <br/>I picked up a Valvoline product manual over the weekend. It clarified some questions about their Racing oil products. It turns out that VR1 Racing Oil is just ordinary new car street oil that says Racing Oil on the label. I think most of us thought it
 was extra good stuff because of those words, and because it said it contains ZDDP (Zinc DialkylDithioPhosphate), which we commonly just call zinc. That ended up being just marketing hype, since even the newer street oils still contain some zinc, just at much lower levels than they used too. Of course, that reduction was done for emissions reasons to prevent wrecking the cats on street cars, certainly not to help the engines. As we know, zinc is considered one of the main additives that gives extra protection against engine wear. Many consider the fact that zinc has been nearly removed from newer street oils to be the primary cause for the rash of flat tappet motor wiped lobes. It may also be a contributing factor to solid roller lifter failures as well. So, of course, racers and gearheads typically like to stay away from street oil if they don’t run cat equipped cars. The thing is, VR1 is API certified as SM rated (check the bottle and you’ll see),
 which is the latest street oil rating for current new cars, as well as older ones so they claim. But don’t tell that to the guys with wiped lobes. In order to meet that latest strict API rating, the zinc level is at its lowest level yet……..so much for Valvoline’s feeble claim of “contains ZDDP”. And so much for VR1 being actual “Racing Oil”. I think most of us expect true racing oil to have much larger amounts of zinc than even the older “good” street oil. On top of that, I recently came across a Valvoline link on the web, where they talked about VR1 being a synthetic blend, though they don’t even say that on the bottle. So………. they don’t make it widely known that it is a synthetic blend, yet they do imply it has a lot of zinc, which is doesn’t. I know many people are quite happy using VR1, but the good it is doing for them apparently comes mostly from it being partial synthetic, not from any help from zinc. Jeg’s lists
 this oil for $5.00 per qt. I was planning to use it in the 540 I’m building, but now I wouldn’t even consider it.<br/><br/>For those of us who actually want truly elevated levels of zinc in our oil, we have to look no further than Valvoline’s two other Race Oils. They have conventional (petroleum) Racing Oil and Synthetic Racing Oil, both of which truly have elevated levels of zinc. Since they do, they say clearly on the bottles, “Not Street Legal”, which is because they will actually ruin the cats on cat equipped cars. And they don’t carry new street oil API ratings. Jeg’s lists the conventional at $7.00 per qt and the synthetic at $9.00 per qt.<br/><br/>Sent from Yahoo! Mail for iPhone<br/>
