I used synthetic on my Jag for as long as I know. Is it gonna be bad if I switch back to Conventional?

 

No, they are even available as a blend from most of the manufacturers.

 

Sounds good. I see Castrol GTX makes synthetic blend. was just curious. Thanks!

 

I run blend in mine as well.

 

Does it run good?

 

It came from the factory with conventional. I used synthetic because mine time out vs miles and synthetic has better additives to guard against acid build up.

The blends are a nice compromise and only a few dollars more.
