Mobil One, AMSOIL, Ach Himmel!

Are all synthetic oils the same? Mobil One seems popular with everyone but
the AMSOIL set. My Volvo dealer uses Castrol synthetic oil.

I have a new 2.5T V70 and need to decide on a lubrication protocol.

Synthetic or Petro based oils - what do you do?

I for one use Amsoil in all my cars, front to back, including a really
keen-o air filter on my Subaru Outback.. I find them to be high quality
products.

I have heard that the best route is to do a break in for about 500 miles at
various speeds, not racing it, then change the oil from petro and a new
filter to synth oil from then on. Since the motor is"tight" when new, there
should be some break in wear.

Mobil 1 is quite good, but Amsoil is probably better. Longer periods
between changes, like 10,000 miles for Amsoil. I think 5000 miles or so is
fine with a quality synth oil. It's still cheap insurance if you plan on
keeping the car for 150,000 miles and beyond. With a turbo, oil is all the
more important.

 

With the way Amsoil is pushed I don't think I'd ever buy it either way. I
usually put Mobile 1 in the turbos and Castrol GTX in the naturally
aspirated cars, for the most part though oil is oil, the important thing is
to change it on time and use a quality filter. Amsoil just screams scam to
me.

1982 242 GLT w/330 000km & '87 240 DL w/242 000km

Have used both and both good, Amsoil had noticable difference, my cars ran
smoother and quieter. But I don't think Amsoil is worth the extra price.
