Dropped off my 2009 Jaguar XF 4.2 l supercharged for end of season oil change before putting away for winter I supplied oil and filter the oil being the Pennzoil Platinum 0w30 Euro LX. About a hour later I got a phone call from the front desk guy at the garage who said that the oil I had provided did not meet Jaguar specifications and they would not be responsible for any engine damage. I asked him to continue with oil change and he agreed with the engine damage provision. He now has me second guessing my oil choice, I think I should be fine I only run about 6000 km per year and change at end of summer driving season. I believe in 2009 you could run regular 5w 30 dino oil so I'm thinking a fairly high grade synthetic should be fine.....any somewhat informed opinions
