I use this in my new(ish) '95 A6QW, seems to be a good compromise
between the $$$ and lifespan of synth versus dino. So far, so good.

My older cars (with 170K and 130K) both use plain old dino, with
more frequent changes (3K versus 5K).

I have heard of problems changing older, high-mileage cars over
to synth, seals that leak, etc. Don't know, but don't figure it's
worth it now. If it's come this far on dino, let's finish the job.
