aja:yea...synergie is better..n more expensive..mayb u can try it on ur evo 1st~~lol..
egnine:i don mean to say ur engine got problem or anything..is jus tat from wat i knw a 4g93 wif 10w40 comfirm no prob wan..if u say turbo or vtec car burn abit of oil tats normal but not normal engine lo..
can i mix 4100 with 6100?
i got some 6100 left from my last change but now my workshop no stock for 6100....so he suggest to mix some 6100.....will it damage the engine?
I think should be any problem, cause I used to mix Motul multigrade 15w40 into my H22AR Vtec (cause 2.2cc engine need circa 4.4L) and top-up the same Multigrade oil into my Evo ...so far ok.
what does circa mean? 4.4l engine oil needed for 2.2cc ker? aja r u still driving ur cf4?
