fyi, dohc has better fc than sohc .. lol ..try google around ..

if u really wan fuel economical then just downgrade it lol ... btw 4g93p is a good engine ..its fc is not high .. i got rm10 to go for 70-80km ... what is ur fc ?

with a 1.8cc the torque diff is not much on both sohc and dohc ... so i opt for dohc interms of efficiency .. juz like solo core and duo core lol ..

btw i m using sohc hehe .. tats y we can see some car likly to be 1.8cc above usually opt for dohc while lower than tat got variations of sohc and dohc ..

i dunno but my usual route is using SiLK highway ..icruise arund 90-120kmph... it all depends on the engine condition of ur car ..if u mod this and that ..naturally ur fc would increase ..

to be honest ..i was first on the impression that 4g92 and 4g93 engines are 1.6 and 1.8 ..so this engines must be eating alot of fuel compare to 1.3 and 1.5 but it is not the case ..after seing my frens 1.6satria and 1.8putra ..even my previous 1.6satria can go rm10 for 70-80km... but note this ..try ti keep it stock ...i din modify anothing except to get a new exhaust set ..lol

ya flooring it is diff case hehe ..is u porposely step the pedal heavy heavy hehe the fc sure will increase ..like when i cruise i slowly shift gear like normal ..around 3k rpm... normal drive la hehe ..

got heavy foot disease then fc sure up up up hheh
