Dear All,

I have 1999 Corolla, Japanese, 1500cc, Auto, 230,000 Km Driven.

a. reduces lube oil (25% after 3000 Kms)
b. pick in 'over drive' mode is very less
c. it feels like lots of load on the car
d. fuel consumption per hour is 12Km/L
e. there is knocking sound coming from engine at speed less than 60Km/Hr
f. car starts in half self in morning


Can anyone suggest what could be the issue? Thank you.
