And, what grade (part no?) of Amsoil do you run in the various wet places on an LT. Motor, tranny and rear at least (what'd I miss?)
Yea - think of switching over to syn, got a guy here in town that sells Amsoil - looking for particulars.
AMSOIL says this on their website.
"Q. I heard that new cars require a break in period with petroleum before you switch them to synthetic. How long should this break in period be?
A. AMSOIL Synthetic Motor Oil can be used during break-in trouble free. In fact, vehicles such as Dodge Viper and Chevrolet Corvette come factory filled with synthetic oil.
Since most new vehicles come filled with petroleum oil, it only makes good sense to change to AMSOIL at the first scheduled oil change interval. New engine components generate high levels of wear metals and can contain contaminants from assembly. By allowing the engine to operate with the petroleum oil until the first oil/filter change interval, the wear metals and contaminants are removed prior to installing AMSOIL."
Someone had posted that the BMW motorcycle accessories catalog stated thay BMW synthetic could be used at the 6,000 mile oil change.
AMSOIL recommends MCV motorcycle 20W50 for the engine, SVG Severe Gear 75W90 for the transmission and final drive. When used with their SMF122 motorcycle oil filter, they warranty against oil related lubrication problems when the engine oil and filter is changed up to 12,000 mile or 1 year intervals (whichever comes first). The gear lube is warrantied for double the BMW change interval (24,000 miles). This is what I have done for the past 70,000 miles on my 129,000 mile K1200LT.
Hope this helps.
