Again, if a newer motor there is no problems with switching back.
Some engines are not manufacture for a tight tolerance with any given seal
to include manual transmission. These are the vehicles you have to be
careful with.
Even with motor that have 100K I have seen leak from several seals that were
used in heavy city driving.
I had tried this in a tranny with over 75K and it started leak on the seals.

Let's try this again with the subject line.
Uhh, no older engines were never a part of the question. The original poster
has a new
truck with less than 20K miles on it and got a synthetic fill by accident.
BTW, I switched an 88 Pontiac 305 over to synthetic about 4 years ago. That
made every
seal in the engine 10 years old at the time. They had aprox. 60K miles on
them. The car
sits in the garage for up to 6 months at a time. That's extremely difficult
on seals. It
doesn't leak oil. And, if I wanted to, I could go back to dino juice at any
time without a
single worry.
Show me anywhere that it says you cannot go back to dino juice after
switching to
synthetic on any engine with any amount of miles. You can't do it.
