Can you leave the amsoil in longer then 3 months? I know some race oils you can't leave in for long term.
If you run certain Amsoil oils and their filters they allow you to go 25k or longer with oil analysis. I change the oil in the SIL's WJ once a year.
Literature from their site.
I make one purchase every year with all the filters and oil I will need for my vehicles. I get the preferred customer discount that costs $20 a year or less if you sign up for longer. It will pay for itself with the discount depending on how much you buy.
