The thing is, I agree with you guys when its all about synthetic oil. I have always used this kind of oil to all my cars.

Im going to run the car now for a while with this mineral. I will open up this topic in the near future to describe my result. I hope some of you will be interesed of the result.

About the the start up wear using the 20-50w oil. Many racing engines use this kind of oil. I dont think this will wear more on the cams and lifters than other oil. I think Jano wrote in a old thread that 5-40 or 50w oil is too thin in cold and result to low oil pressure. I cant find the thread now but I remember he wrote it.
