How much oil does a suzuki intruder 1500 hold also what weitht?

The Intruder 1500 takes between 4 and 4.5 qts with filter change and uses a 10W-40. I was surprised by the weight, but that is what is on the cap. I even verified it with the Suzuki dealership.

The Intruder uses 5.3 US Quarts for an over haul, 4.5 US Quarts with Filter Change, and 3.9 US Quarts for an oil drain with out changing the filter. That is the factory spec.

Per the Factory Service Manual API Rating SF or SG with a viscosity rating of 10w/40 is the only thing in the book. I've been using Bel Ray V-Twin Full Synthetic in mine for 18,000 (after initial 500) miles but that was my decision and has nothing to do with the factory specs.
