I've been using and recommending AMSOIL for more than 10 years.
Make the comparison and decide for yourself.  
AMSOIL saves you $$$$!!

Conventional Motor Companies recommend 3,000 mile drain intervals

Conventional 5W-30 Motor Oil

(40 quarts & 8 oil filters needed for 25,000 miles)

40 quarts x $3.00 per quart = $120.00

8 filters x $6.00 per filter = $48.00

$120 + $48 = $168.00 (Total cost for 1 year)

AMSOIL Recommends 25,000 mile or 1 year drain intervals

AMSOIL 5W-30 Synthetic Motor Oil 

(5 quarts & 1 AMSOIL EA Filter needed for 25,000 miles)

5 quarts x $9.55 per quart = $47.75

AMSOIL EA Filter x $16.00 per filter = $16.00

$47.75 + $16.00 = $63.75 (Total cost for 1 year)
