I use both. Honestly, I can't tell the difference except in the price on the oil filter. I use it because I dont know if other oil filters are compatible with mobil synthetic oil. About the oil relocation kit. The idea is good but finding a good location is the hard part. I use the greddy oil filter relocation but not the hoses that are included. Because of the under tray covering, I decided to mount the oil filter relocation next to the tranny. Pros would be easier access to oil filter and no oil spilling onto the under tray. Cons would be having to get new longer high grade oil lines and "maybe" putting more strain on the oil pump due to increase oil amount and longer oil lines.
