Ok, instead of quoting every post that might have something to do with this response, I'll just give credit to everyone involved with this type of response.
I did contact Synlube and chatted with Miro for a while about 3 years back, when I had the time and fundage to play with new technology products and synthetic oils. He was fine to talk to on the phone, but I do have to admit that nothing was really said to convince me to fork out the start up cost for running Synlube.
I agree with the posters that also state that the 20 weights are strictly for CAFE purposes, which is why I use a 0w-30 in my crankcase year round.
And I also have to agree that now up to 40 pages of this, and STILL no legitimate numbers of elements, components, or such, is getting to be a little much.
In conclusion, if you're not ready to try it by now, will you ever? I don't think that even numbers will help the cause at this point...
