At how much RPM Should i change gear of Liana to get optimum average on CNG & Patrol? please advise.
I think it should b abt 1200-1500 wid ac on cng.
isn'tn 1.5k is too low to change the gear? wot about without ac on cng and patrol?
as a general rule....you should shift up after start driving as quickly as possible....that saves you alot of gas.
the rpm level is dependent on your speed and the load on the engine.
I think change the gear between 3000-rpm & 4000-rpm
its better to use search option ... as this topic was discussed in detail some time ago ...
Divide RPM range into three equal parts, and change the gear within the first 1/3 range of the RPM to get an optimum fuel economy......Like if the RPM meter ranges upto 7K, changing gear at (7/3=2.3) 2.3K will give you nice fuel economy(y)
