So far, my 1.8 Litre VTEC hasn't consumed a drop of oil using M1 0W-40. It only has been about 500 miles but I am happy with it so far. Besides, I think a 40wt M1 oil is okay for engines that normally ask for a 30 wt, considering its viscocity is 14.4(I think) at 100 Deg. C, and from oil analysis seen here, it shears back to a 30wt anyway (about 12cst at 100 Deg C). This would explain why honda owners, especially Prelude owners don't really burn much oil until after the 1500 mile mark. I would be more inclined to take the M1 0W-40 up to the 6k interval than using M1 xW-30 oils.
