1996 Beretta 3.1L V-6
After reading all the glowing reviews of Mobil-1 synthetic oil in
here, I decided to switch over from regular Pennzoil 5w-30 to
Mobil-1synthetic 5w-30. I just talked to my mechanic to schedule the
oil change (too cold for me to do it), and he advised against it.
He stated that there would likely be leaks in seals, etc. after
switching to synthetic, and that I would probably harm the engine if I
switched to synthetic.
He advised to stick with what I've been using.
Is this correct, or is it something that only applied years ago, if
ever at all?
The car's going in for the oil change next Tuesday so I need help here
Many, many thanks to one and all for any help/thoughts/opinions.
