Hi
I am not well versed in mechanical / electrical issues hence looking for some advice.
I am running a Honda Fit GP1 2011 and currently clocked in around 160,000 km. The car was doing approximately 13 - 14km /L in colombo and 16km / L or more on the expressway
In December I did a tune up at Stafford and changed all plugs *( purchased at Te*k M*t*rs). Before the tune up I did my service at Ar*b*an M*t*rs) and we were using 10W oil. At stafford they changed it 0w.
Since the tune up I run almost over 5000km but efficiency has dropped down to 9km /L in colombo
Any idea what should be checked? And where i can take it to?
I showed it to Stafford and they say nothing is wrong and they are clueless
