Sir gear oil was changed recently kixx API GL4 75w90. 2.5Litres and it was filled from pipe using Keef while the car was totally firm on the ground. The porblem was there before too. As i bought this car used. 66000 on the ODo. Im pretty sure the meter was reversed. But till now i have changed gear oil twice. And now the ODO is 125000.
Secondly i have also used Liqui moly gear additive just to give it a try that it might reduce the sound but nothing changed. I used 2.5 tubes or liqui moly gear additive in it.
It comes whenever car declarates. It's like old cars gear sound. Wining.
For the oil part car's engine is really in good nik. Since 66000 i have been using kixx 5w40 as i didn't know th correct oil grade for this engine. Will surely opt for 5w30 from next oil change.
One more issue I'm facing from 3-4 days is that when for e.g im in 2nd gear and crossing a spead breaker and when i again pull the car in 2nd gear it starts to knock from 1000rpm to approx 1200 rpm. Then it goes away. I don't know if its the bad quality fuel these days or something else. (i have got its MAP and vvti solenoid cleaned today) but no difference.
You have always helped alot.
