Call up a Mobil Lubricant distributor. They'll be able to tell you where to purchase.

According to Gus at Baxter's, any JASO certified full synthetic will work fine. Triumph has transitioned to the Castrol brand (a little cheaper) and I have used Amsoil in the past.

Be careful to buy the JASO Mobil 1, not regular Mobil 1, IMHO. I think you have to buy the Mobil 1 motorcycle oil in order to get this certification. Mobil itself doesn't recomend using the regular Mobil 1 in bikes. I ran Mobil 1 for a while myself. 'Course that Rocket went on to have the dreaded output bearing failure...
Valvoline, Shell Rotella, etc., are commonly available at auto parts stores and are JASO certified.

I am having a hard time getting this oil, its the only oil I've used in my R3 since I bought it in "04. Anyone have a line on this oil?

You can get the 10W40 version at Autozone. Look for MX4T Mobil 1 and you can get it by the quart (get 5 minimum).

Any good synth motorcycle oil will do. They are not like HDs that need special Harley oil. Shell and Motul are brands that both make an oil to suit a Triumph.

You need to find an ISO number for your oil or use a specific motorcycle oil 15w 40 only refers to the viscosity of the oil you need to find an oil that has
compatible additive package
I have used a regular multigrade oil in a motorcycle before and found myself shelling out for a new clutch because the oil had ep additives which caused the clutch to slip so again make sure you use a motorcycle oil or ask an oil supplier for recommended oil and get it in writing otherwise they will say anything
