Synthetic oil in my Jags ?? Opinions wanted

I recall when these synthetics made an appearance in the [60's] ?

Seems I recall that it was recommended to only use them in NEW cars for some reason.

Seems there's a new revival of these that they "push" at the auto stores.

I've always used Castrol 10/50, but I'm wondering if there is any advantage or virtues to the synthetics.

What do you think fellow Jag lovers?

Depends a great deal on what you drive and how you drive it. Most enthusiasts in Europe uses synthetics as a matter of course in any performance car. Certainly you should always use it from scratch in a new car which is going to be driven hard. On the other hand, if you have an old car which is a bit loose and burns oil - as early XKs were exptected to, for instance - then no point in burning or leaking expensive stuff. All the guff about synthetics not being suitable for certain types of car is just old wives tales. Might have been true once. Isn't now. Never had any problems switching an older car onto a synth or semi-synth oil. Looks expensive on paper, but then you don't have to change it so often.. I stick to an annual oil change on my (relatively) low-mileage cars.

It's by far the largest and most lively Jaguar forum on or off the net. It is completely searchable and one can find answers to most technical questions. The synthetic oil question has been discussed to death and you'll find opinions from extremely knowledgeable and experienced folks. There are separate forums for most Jaguar types. See ya'll there!
