01 Cobra owners, can you help me out

[Qobra01]

Hi Everyone, I just found this site last week and am amazed by all the great info being passed along, I was hoping some of you fellow car owners can help me out, My car runs very smooth and strong , its a blast to drive, but I notice when changing the oil I notice some very fine shaving in the oil in the pan I drain the oil into, I was using Ford syn/ Blend 5-20, but in the last change I switched to Mobile 1, the car only has 4100 miles on it. I take it off the road in winters and only really drive it on weekends, but have taken to the track and auto x a few times. and not afraid to run it through the gears on occasion. Besides the problem with the cold 1/2 shift every body else has it also makes a ticking noise at start up and goes away almost immediately, other than that the car runs fine, am I being neurotic with the shaving and the start up or is this somewhat normal, the car is still under warranty, any input would be appreciated Thanks!

I got a pro 5.0 coming to help the shifting I hope...I get a buzz sometimes even, worse when its cold, like its not going into gear right.

I would ask why not use 5w-30? I also put mine onto mobil 1. Right now my oil changes are done at the dealer so I don't really get to see it but I would say no its not normal, you do have very few miles though.

Sounds like it might be a good idea to run an oil analysis:

Don't worry about the cold start "ticking" problem; it seems to be a common occurrence so long as it goes away after a couple of seconds...

Why use 5w30?

Thanks for the input!, I also did some checking today with 2 different mechanics at two different places and it seems (I hope) both situations are typical, and it was 5-30 I switched to. THX!

Why use 5w30?

In a nutshell: You are fine with either weight oil (20 or 30) in most applications.

A lot of people still use the tried & true 30 weight oil (and afterall, that is what Ford has recommended for years before the '01+ engines were sold).

However, the biggest reason that Ford recommends the factory fill of 5w-20 is for CAFE purposes (Corporate Average Fuel Economy , read: $$ money savings for Ford $$). There were some PDF documents floating around on the net from EPA, outlining Ford's rationale behind the decision to use the 20 weight oil instead of the tried & true 30 weight oil. Again, you have to think of this from Ford's position, they were trying to trim costs, via fuel economy through their CAFE numbers.
