You can switch whenever you want! IMO Redline is a little overkill for DD duties, if your not burning any oil with the M1 then I wouldn't worry about it. I ran M1 in my old STI for over 50K and never had any problems. CRZTRBO I would worry more about what viscosity to use rather than brand, since you should change your oil before and after a auto-x day anyways I can't imagine any oil hurting anything in that short amount of time. I would deffinitely switch to a 5-40 or 10-40 for the day. Also, I would also get a oversized(higher cap.) oil filter if you don't already do so.
What motor oil is the best?

i think i like the idea of redline as well lol. nope, i do not burn any oil nor do i leak any. i just like changing it often because i like new

Fresh oil is always a good idea, if your looking for a better oil thats readily available you could try out Shell Rotella or German Castrol. Shell can be found at WalMart and most auto parts places have GC. If you want Redline you would need to go to their website and search for a distributor near you.

They're marketed towards vehicles that get abused and used which translates to trucks. :lol:

Don't get caught up on stupid shit like that though. Its simply marketing. If it were marketed towards high performance cars it wouldnt be $20 a gallon. So I am happy its not.
T6 will be just as good as the other more expensive oils.

LIC Motorsport recommends 10w30 i read it in facebook lol
my advice if money is not a problem amsoil/motul.
It is full synthetic.
I would stongly consider moving away from the blue Subi filters, the Tokyo Roki(black) ones were awesome but the blue(honeywell) ones not so much.. They have paper end caps like a Fram filter.
I use the oversized Purolator Pure One filters(part# PL14610)or PL14612 for stock size. For 7 bucks you cant beat them, they sell them at most autoparts store. There was a thread about filters on iwsti and they cut a bunch of them open, this one came in second behind the old Subaru(black) filters. Its about 3/4 inch longer than the stock ones but clears the stock under tray(in the GR anyways).
