Smoothing out stock M20

[cabbman]

So my using 0w40 isn't such a bright idea?

And does anyone know if these things sounded this way off the showroom floor?

I had a similar question in mind. I suppose it all comes down to this present-day oil formulation then, ay?

I've been using 15-50 Mobil 1 for quite some time and felt it was a definite upgrade from, say, a 10-40. I'll have to give this GTX HM a shot then. Good material, guys.

I also am a fan of the sewing machine, i was first introduce to it with vids of built turbo volvos and have never grown tired of it.
