AMSOIL....is it worth it

Does anyone use AMSOIL? I was looking at it and $9 a qt. seems pricy but they say you only change the oil every 25,000 miles. Any input on this stuff??? I always use Mobile 1 and change oil 6K - 7K miles. What is the difference between these synthetics???? Even if I go to it I will probably still change oil around 20K. I just dont understand how this stuff could last so much longer.

 

if i were you....i'd stick with using the mobil1. i dont care how good an oil company claims there stuff to be.............no way in hell i'd run my oil no 25k miles. i'll stick to 5k changes as usual. have never heard any negative about amsoil, just good things, but mobil1 is great too....just my .02.

 

I know what you mean.. Ity would be real hard for me to NOT change my oil but WTF is this stuff really that good????

 

It is really that good. I swear by Amsoil...Only change the filter every 5000 miles but keep the oil for 25,000 miles.

I run it in my bikes and my truck. My oil still looks brand new after 10,000 miles.

 

Tried amsoil didnt care for it mobll-1 is all i use now with mo-1 filter
