Royal Purple 75w-90, I am not an expert in lubrication but so many people have used that (weight) in a host of Toyota platforms over the years and I have not once heard of an issue. It does not need to be royal purple, I just happen to get step discounts through work so mind as well.....
I used Raam Mat BXT II and Ensolite from RaamAudio based on a recommendation from a family member as a good product at reasonable price. He is much more of an audiophile then me so I can't speak to how it compares to other products but was told it compares well at a reasonable price...not the cheapest, not the most expensive.Happy with the results, that and swapping front speakers made a huge difference for me. I have no plans to turn this into a quality audio machine, only to make it better then factory/make up for putting mud terrains and a roof rack on, as much as possible.....
Got the bumper and lights mocked up tonight and the cutting done on the OEM bumper, tomorrow should be able to finish it all up....gonna be awesome
