RE: [ST] Oil thread time!

You must have a different service manual than I do.  Mine says all of the
following but it says to use ...10W-40, 15W-40 or 15W50 fully synthetic
motorcycle engine oil...


Actually, page 8.5 of the factory service manual says,"All Triumph
fuel-injucted engines must be filled with 10W-40 or 15W-40 semi or fully
synthetic motorcycle engine oil which meets API-SG or API-SH *AND* JASO
MA specifications."  Than it says not to use 0W or 5W oils or 10W-50
oils.  It also says racing 4T meets and exceeds these minimum specs.
Under these rules, MX4T, which is a 10W-40, is perfect.  15W-50 in not
mentioned in the service manual.


It further says to use an oil that meets API-SG or API-SH specification and
does not mention the JASO rating.
