In light of my observations, and rewatching the videos posted in this thread is any body with access to a dyno that is currently not running Schaeffers willing to Dyno their truck with current oil, change to Schaeffers (I will buy and send the oil to you filter too, if you need it) Then do another Dyno or two (maybe one directly after changing, and one a couple of hundred miles later) and then post the results back here along with any other observations? PM me if you fit the bill and are willing to donate your time and my mulla. Thanks

I believe you will find the support you need. When I was 16 I had a 71 chevelle with the 454. I swicthed to Amsoil, The base rpm went from 800 to 1100 with nothing more then an oil change. I have not gone back.. everything I have driven since has been amsoil. I feel very strongly about synthetic oils being a better choice..Have fun with your testing.

 

Yeah the SOTP feel is amazing, havent really driven enough to check mileage yet but I am getting close to needing to fill up (can't justify driving to check mileage) but the truck performance sure is different.

 

An after thought though, keep it clean. Get the secondary filtration. No rush. But keep it clean.
