What's the story with Amsoil?

[noway]

I just bought an '05 Sti and the dealer recommended Amsoil.

He doesn't sell it, so that's not the reason, Subaru makes no such
specific recommendation.

I intend to maintain a strict 3000mi interval, so is there value in
Amsoil vs. Mobil 1?

There is no value in either if you change every 3,000 miles. I use Mobil 1
and change at 5-6,000 miles with a OEM or PureOne filter.

Same here. Mobil-1 and a Fram filter (I like Fram!) ever 5K on the 4Runner
and WRX.

That's where it came from.

That's like asking, "Is the Mac really a better operating system than
Windows?" (or, vice versa). You like to start religious wars or something?

Well - Amsoil has always been flaky when it comes to getting certified
via the API's EOLCS system (the API "donut"). Only their XL-7500 series
goes through the certification process. There have been rumors that
Amsoil doesn't meet all API specs. It's not that it doesn't protect
engines, but there have been allegations that their products have a
boosted ZDDP level, which may foul catalytic converters.

From what I can tell, the actual product is fine. However - some are
turned off by the often pushy Amsoil salesdroids who rave about the stuff
all over the auto NGs. Red Line is another niche maker of lubes. They
have a loyal following, but few people get upset at the mention as with
Amsoil. They only sell through regular dealers (I've even seen some of
their stuff at Pep Boys).
