I was just about to change the oil on my S2K for the first time using the How to instructions on S2KI and I was wondering if someone can tell me what area's need to be lubricated and where can I find them (also what lubrication should I use).

 

There are no "zerk" fittings on this car and thus, you don't really "lube" it (like when you go get an oil change and a "lube job"). If you really feel the need to do it, you'll have to tap and install all these fittings in all the ball joint boot areas.
However, you can still take care of the rubber boots themselves - something that most owners neglect.

Of course, there's all the door, hood, trunk latches and hinges to squirt some White Lithium Grease onto and all the rubber weather seals on the windshield, soft top, hardtop, under the hood and under the trunk lid to treat with some sort of silicone grease.
