Shell Rotella T is sold @ Walmart, as is heavy duty Delo 400 in a 15w-40.

Don't listen to horror stories regarding oil.

Just avoid anything that says "energy conserving", and you will be fine (synthetic or not).

All oils mix, as they all come form the same place. Even the fancy synthetics (Mobil 1/ Castol Syntec) are simply super-purified base dino oils. You have to spend some real $$$ to get 100% man-made synthetic product. And for daily riders, it's not worth it.

Oil is oil. If in doubt, chage it more often.

I've gotten to the point where I just pour in the cheapest crap around and change it often and consistently.
