My dad once told me that the 90 wt was atrick he used in the past on a couple of cars he had, oncethe engine noises start coming, dump thatcrap in and get rid of her, no noises whena buyerstarts her up to hear her run

 

Hey EMS,
where did you get that big ol stirrin stick?? Same place you get your 90w??

 

Amsoil here too. I change it probably more often than needed. I change it after every couple viciously dirty rides. Otherwise every 500 miles, but I usually go mudding and deep water stuff before that ever happens. I also use the K&N oil filter, and change it after every two changes.

 

Yea it was on the shelf next to "things to **** people off" and right above "do it because you can" LOL
