Whats up everyone,

I just recently bought my 98 XJR and i love it. Low miles one owner car, Black on black. let me tell you , I am a car enthusiast and this car has to be hands down the most ban for you buck. Anyways I want to get my oil changed this weekend and was wondering what oil you guys suggest I use. Should I go Synthetic? and what weight of oil is ideal for California weather.

Since I have your guys attention I have one more question , my car is flawless but I did notice that the lower headlight surrond under booth headlight(the plastic body piece covering the headlight) do no sit flush with the bbody. Is there a way to adjust these or is this how they are suppose to be? Thanks guy and I am super excited to start interacting in this forum
