I am kinda new in here but I have been in the automotive industry for many years however.

I know we have discussed many upgrades and performance options. This being my newest truck I would love to get some input about what you guys use and why as far as maintenence items. Namely spark plugs, oil filter, oil, trans fluids and diff lubes and the reasons why? I would love to get links to sites where these items have been tested and which ones stand out above the rest...

 

well there are also tons of posts about this stuff.. in my personal experience i love amsoil... they make great lubrication products... they have advertisments all over the site too they are a sponsor and a great company to deal with.... i have tryed many oils and by far i like amsoil the best... i use a wix oil filter because in many different studies they came out on top...... for spark plugs should be replaced with the same as the factory.... champion copper plugs i just did them and they are the only ones you should need platinums and all that are overrated...
