I just fully rebuilt my engine and new clutch and such and I waited 700 miles before I hit vtec and during the whole break in period would not get over 4K rpms... Then on 700 miles I changed the oil and put 10w 40 in and new oil filter and drive her normal now =D

USDM 4G VTEC

after that if done correctly there shouldnt be any problems

change it and it shall be fine.....

remember synthetic oil leaks from wherre normal oil doesnt
