We will be including some information in the future with our engines about the
oil. When you stand behind an engine but are not there taking care of it or know how it is getting treated you need all the help you can get. Most people will buy the cheapest
oil they can in most cases thinking they are all the same.
I have talked with people about some of this till blue in the face and I can not make them buy any certain kind of
oil. You are correct about some of the oils having around 1200 PPm or so of
Zinc but you also need to know how much detergent they have and the type. I figure we will make a repring of some of the Jo Gibbs numbers and include with our engine packages. If a person buys an engine from us they should consider what oil we tell them to run.
Some of these other oils will do the job in a lot of the cases but if you can get somehting that is better for your engine why not run it. Like I said before the lower the spring pressure, lower the rpms the easier you are on your engine the less important the oil becomes.
I do not think the Jo Gibbs stuff is much higher than any other high performance oil if you buy it from us or some WD dealer. Like mentioned earlier have your oil company send all of the information on their oils so you can check them out.
Good luck, Keith
