Change manual gearbox oil on 2014 Fiat Linea?
Hi,got a 2014 Fiat Linea 1.3 multijet Euro 5 motor manuel gearbox at 200000km, I've spoken to couple of mechanics about changing the gearbox oil, I've been told that manuel gearbox oils don't need changing unless something was wrong with the gearbox, been told they would just top up the oil.just bought the car not sure if the oil has ever been changed before.should I change the oil or keep topping it up.Thank You for your help
Why do you need to "keep topping it up"? Is it leaking? Change the gear oil, these "mechanics" you're dealing with don't seem to be qualified for the title. Changing gearbox oil on a manual transmission won't do anything to help it if there's something wrong inside. They are splash lubricated shafts and gears, the only way they can really break is if you drive them low on oil constantly, or are a really terrible driver and wear out the synchros. If there's an internal problem like this with these things, new gear oil isn't going to fix it. Very expensive new parts will. If anything, not changing it will cause increased wear over time as debris builds up in the fluid. It also slowly breaks down. The debris wears out bearings, gear teeth, etc. not to mention the slow breakdown of the oil reduces lubrication quality. Change the oil.
I would change it
