Hi I'm new to jaguar!

I have just bought a s type V6 3 L and I was wondering which type of petrol to use. I put unleaded in first the car ran well. So I then put a better type of fuel in to see if I would get better fuel economy. but the car engine light blinks and now is on. When I go up hills the car judders a little. when car is ideling it judders a little. Have I mest up ?

Hi Peter,

I ran mine on standard  unleaded most of the time, with the occasional 'treat' of the higher 97 octane when I was on a longer trip. It's unlikely the better fuel would've harmed her, unless it was a bad batch.

It's arguably more likely she needs a service, do you have a service history and can you see when the plugs and ignition coils were last done?

Good luck, Russ

Hi Russ thank you.

I checked fuel cap and whent for ten miles drive to the car upholstery fabric intereas for new headliner, he has matched it up and will have new headliner on Monday.

Sounds good Peter, you've got a good one I suspect 👍 The left hand cylinder bank is under the inlet manifold, so sometimes the spark plugs and coils are neglected on this side. But I imagine the Sergeant Major would've made sure these were done properly. If not, the V6 will run rough, as you describe 😉
