I have just build my whole engine here are the spec on ithttps://honda-tech.com/zerothread?id=961937 anyway I have 700 miles on it right now using valvoline 5w30 oil, is it safe to change to synthetic 5w30 or 10w30 what do you guys recommend>? thanks for your help also Im in FL hot *** weathr right now

 

anybody?

 

I was told not to use synthetic oil until 10,000 miles. also I would suggest using 10w30 over th 5w30

 

my tuner said at 2000 miles.

 

thanks for your replys anybody else that can share more light on the subject?

 

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

 

most of the engine break in happens withing the first 100 miles

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
