Whom it may concern Acura suggested oil change is 7000 mi or 1 year using Acura Syn Blend. Every car has it's oil, it is based on how often you change it and how you drive the vehicle. -Mr. Obvious
Conv, 3000 mi change, Acura or Mobile Super.
Synthetic, 3-4k, Mobil Supersyn
Syn Blend 4-5k, Acura or Castrol Syntec
Fully Syn 5k+, Mobil 1
Fully Syn Racing 3-4k, Royal Purple HPS for tuned motors only.
I have heard of some good Japanese oil brands, but never really wished to test them. All Acura/Honda are suggested with mobile products.
