Hey all, what are your thoughts on b10 bio diesel and the cp4. Would this not help it last longer. Anybody having success running bio with the added lubricity? Also, bring my truck is an early build 2014 truck, built in September 2013, do you think my cp4 would be the updated version? Ive heard that it was the 2015 trucks and I saw posts where they said in 2014 they changed it. Wasn't sure. Thanks
