How long do you guys go on the % of oil usage,I am at 7000 miles on my oil and still 32% im using lucas oil products.. al

I go until it tells me to change it. I don't look at the miles at all. That'* what the oil life monitor is for.

When I do my next change I'm switching to AMSOIL which only has to be changed once a year, with filter changes in between.

I just got a prefered customer from a amsoil rep I ran into at seekonk speedway,that will be my next oil also,that filter setup is like 400 bucks..the dual filtration system..

I'm not using that one .Just the Signature series oil and Wix filters.

thats what im going to get the 5-30 syn.

you dont use the amsoil filters?

Nope, they cost too much and Wix has been proven to be good for many, many years.

Actually, scratch that. I just looked at my dealer pricing list (got a good hook up) and I can buy enough oil and filters (12 quarts and 2 filters) to last me a year for both vehicles for less than it would cost me to buy conventional stuff for one.

Oh, and I think you're talking about their by-pass systems Vendo. I'm not gonna get that considering I don't have a diesel and won't be make much soot.

on my gxp i used to change it about 40% or so, usually go by mileage or color which ever comes first

i change my oil ever 5000 KM not miles

40%?

You're stuff is still near perfect!!
