I bought my honda accord 90 in february 2010. Ever since i use the car every day for long and short trip within Nigeria. I do engine oil and filter change every 3months. But I have not change the gear oil. when is the appropriate time for me to change the gear oil? Presently the automatic transmission is working fine and there is no problem whatsoever. Your advice will be most useful. Hoping to hear from you soon. Thanks

 

The book says every 60K. Me, I'd do a drain and fill (one cycle) every 20K but that is me.
