    Running Rotella T4 CK-4 in Generac GP8000E?

    Should this tire be ok?

    Ran over a nail, and I didn't realize it until the back end started to sway a little and I pulled off and the driver rear was flat.

    2000 Kawasaki W650 10w-40 Quaker State Advanced Durability API:SN 16K Miles

    Previous owner changed oil every 1,000 miles with QSAD 10w40. I wasn't sure how far along miles-wise the fresh oil in the bike was when I bought it, I figured under 500 miles--as it was still clean.

    Quaker State Advanced Durability (QSAD) 10w-40 API:SN

    I didn't submit this. This sample was done by Project Farm. I just took a screen shot and posted here for convenience. The link to his video is here: https://www.youtube.com/watch?v=-zHlxeu_yuM (Is Oil Good After 70 Years? Let's find out!). At around 10:00min + 27 seconds he shows it. He...

    VOA for QSAD 10w-40?

    Non-energy conversing oil weights usually seem to have a lower Moly content than their thinner kin. For my application (m/c) this is good. However, I am trying to find a VOA for Quaker State Advanced Durability in 10w-40. If anyone has, please post. It seems most SN oils have around double...
