Cheapest place to buy Amsoil synthetic motorcycle oil?

Should I get 20w 50 or 10w 40? Bike is an 07 Kawasaki EX250.

Pep Boys. 20w 50

ur bike calls for a 10W40go to the Amsoil website and they can find local dealers where you live, I just purchased a 12 qt case of Amsoil 10W40 motorcycle oil and I got it for $6.70 a quart, yes its expensive, but one single Amsoil change will last 3 times longer than using regular oil, I run Amsoil in my bike for 8000 miles, but I change the oil filter only at 4000 miles then just add enough new oil to make up for what i lost changing the filter, REMEMBER, Amsoil Oil will last forever, but the OIL FILTER WON'T !

Save your money and buy valvoline synthetic oil. The company has been in business a lot longer and has the backing and support of many auto and bike companies.

Sign up as a Preferred Customer if you want dealer prices but don't have an interest in building your own business as an Amsoil dealer. You can always upgrade to dealer if you decide to. P.C. memberships are $10 for 6-months. (you'll save that on one oil change). Your bike calls for Amsoil 10W-40 synthetic motorcycle oil. As a P.C. you can buy it for $6.85/qt versus $9.20/qt, shipping and tax not included. If you can't find a dealer near you(I'm in Clearwater, FL), sign up as a P.C. at my website and order online: http://www.number1synthetic.comor contact me for questions/assistance trull_synthetic@yahoo.com, 727-812-4181. Info about the P.C. program is available at my site after you click'Shop Online', its at the top, left.
