Interestingly, my Jaguar has just developed an oil leak. I put in Mobil 1 Synthetic, and then it started leaking. I guess now I'm just going to replace it with Castrol Oil. Then hopefully it will stop. I just took a trip to Tampa though, and got 27.5 MPG average at 59 mph in heavy traffic, then it dropped to 25.5 at 73mph. Amazing- I have loved my Jag. Hopefully I can post some pornography soon-I mean pictures of the car, that is- I just cannot get this website to let me post or look at pictures. It's hugely upsetting. If anyone knows why I can't access anything please tell me. Any news about that oil leak/ cause? Thanks.

 

Welcome to jaguasforums.com. I know that you are anxious to get started but we have a 10 post minimum. Once that is satisfied you will be given you opportunity to post photos and see other links. Please be patient and enjoy the site.

 

As for your oil leak please keep in mind the mileage of the car and the previous owner’s maintenance history. Many owners were not open to using synthetic lubricants and when you introduce it to the car it is like giving yourself a glass of prune juice, It will clean you out. It will also develop leaks that in the most part are minor until the seals adapt to the type of oil. Be patient and check it often to see if it is still a problem.

It only has about 40,000 miles- and I'm fairly certain it was poorly maintained, a it has few records of maintenance. So do you think I should keep the synthetic or switch to petrol (Castrol)?

 

I think you need to leave it alone and keep an eye on it and see what takes place. Keep in mind the history of the car is a little vague so do not panic you are doing the right thing. Or you can get your favorite beverage sit back and watch it drip. Just keep an eye on the level.

I was thinking about your leak, is it leaking at the oil filter or drain plug? If not things should be ok! If it is check your seals at the filter and the drain plug.
