I just got my bdx oild delete in the mail and ready to install it, just wondering what everybody is doing for lubrication, bdx instructions say you don't have to do anything but everyone else says you do, should I just slap it on and go? Or should I fill the cavity with oil first? Or use a grease zerk or banjo fitting with a spall reservoir. If using a zerk what type of grease do you guys use, thanks in advance for any info. Just stumped on all the different stuff people are doing
