I've had some free time and I've been intrigued by additive packages oil companies add to their oils for additional lubricating and anti wear detergents and longevity of the oils...
I'm interested in the zinc, moly, phosphorus and calcium levels of oils and their desired effects...
Motor oil I was told a while back is like Pizza.....You can get dough and add Ketchup on it and a few slices of American Cheese and technically you have a Pizza....You can market it to be the greatest ever and you will have a certain percentage of the public who will buy it...
I think motor oil is the same....
So I called three oil companies to get their VOA on their 5w-20 oils and ask their opinions on zinc and phosphorus and calcium levels on passenger cars and light trucks..
I enjoy the VOA's on here, but different labs vary so much..
Dave from Redline was very open and cordial. He was free to give any numbers that I asked for.. He also said that it is high phosphorus that is a concern and not high zinc in newer engines.
The Redline 5w20 has a phosphorus level of 1375 ppm says Dave and that is not high enough to cause concern in today's engines as per Dave...
I called Castrol for info and they said that they do not make public their figures...
I called Mobil and they said that they only state the Zinc and Phosphorus levels of their oil...
Why all the secrecy especially with Castrol...?
