Consumer Reports thinks they are all the same. I'm thinking there's probably a larger difference between Mobil and Motul or Redline than Castrol.
A lot of people have been ragging on Mobil 1 lately, so I'm switching over to Red Line 5w/40 in my 986 for the next oil change to see if there is any truth behind the coolaid.
if it quiets down the cold start up clatter or revs smoother I'll be happy enough to justify the 9 bucks a quart,otherwise, it's back to Mobil.

Go read what they say on the LN engineering site..

My engine rebuilder said to use Castrol Syntec which I get cheaper than Mobil1 at several sources in Canada. I tend to listen to those that rebuild. Besides, the cost to rebuild or replace is rather high compared to the cost savings. PO had overfilled the crank with 4 extra litres. I got a deal including the cost of a rebuild ...

But, it's your car and your choice.

I've used Mobil 1 5W-40, Motul 8100 5W-40 and both oils resulted in good used oil analysis reports but both had startup noise -- I changed to RedLine 5W-40 and the startup noise is gone (thank you POEs!).

Hi, I have read several posts now that have stated Redline oil has reduced or eliminated start-up clatter. I would like to try it. I am wondering where you buy it for $9 per quart.
So far, $11 seems about the lowest I've seen. Thanks
