Was this in cool weather? You probably just noticed the thinner oil is all.

It's 85 degrees. And the " thinner oil" part..isnt that the point? Besides the fact that Amsoil is the best, slippriest oil money can buy.

Amsoil is the highest rated synthetic. Even over Mobile one.

well worn down oil will feel dull then you go to fresh oil, its nice and peppy again...

if you switch back to normal oil... it will be like that too, the only real benefit of having the synthetic is that it lasts longer than normal oil...

In some cars Amsoil works better, in some cars Mobil 1 works better. Bottom line is that both oils are great.

BTW... Amsoils tests are very subjective and somewhat misleading... like all advertising.

With the Amsoil preferred customer discount, you can get it for less than Mobil 1.

Any power gains from switching from 5w-30 to 5w-20 are in your head though.

What kind of filter are you using?
