i'm currently using conventional ATF and normally flushed every 30k...what about mobil? i heard amsoil can go up to 60-90k before needing to flush out...just want to compare....

 

Yeah, about 75-90K sounds right.

 

AMSOIL Is formulated for extended drain intervals and can be used for up to three times longer than conventional fluids. I've been using AMSOIL ATF for nearly 20 years with outstanding results and currently have it in the transmissions of many customers. I also have a commercial account here in south Texas which uses AMSOIL 10w-30 and ATF in ~130 police cars (Ford Crown Vics with the Police Interceptor Pkg) and they are very happy with the results...the vehicles run better and they have not had a single engine or transmission failure with the products. Based on my personal experience, the used (AMSOIL) fluid that comes out of the transmission at subsequent service intervals looks as good as the new stuff going in...and the pan is essentially clean...it's impressive.
