0w20 for track? From M1,PUP 0w20, or Redline probably. Looking at M1 website,R18's have 0w20 or 0w30 recommended. Change it before you track and maybe after.If you are going to run this car hard,consider changing oil and filter every 5k tops.You got a nice car,oil is cheap compared to engines.I got the 15 Civic SE 1,8L and have run 0w20 and its been trouble free. Changed FF at 6000, took one free 0w20 Honda Synblend 0w20 freebie and then used my last two freebies and brought 0w20 Full Synthetic.
