I have a 1992 with over 200k, and I haven't gone to synthetic motor oil because of warnings about leaks. The car already has a slight seep from the rear main seal, and a leak there would be a $serious repair.
Then I came across a discourse in the FAQ on motor oil--someone in the discussion said that Castrol Syntec was not a true synthetic but merely a super-refined dino oil.
This correct? If it is, then would it give some of the superior performance of true synthetics while not causing leaks?
Thanks for any help you can provide.
