What Oil Are You Guys Using?
Tri recommends 10-40 or 20-50 full syn, and until recently I was using factory 20-50, but at my 10K service with new plugs they added lighter oil-and man this thing is faster than it ever was revving like mad-I capped off a 110 to 140 mph run that seemed instant (usually it takes a while to go from 130-140...not this time! Seems like at least 5 extra horses are showing up for work-despite the weather getting crappier! It also seems to be running cooler.
I know lighter weight oil makes more power/economy, but I wonder if the heavier weight should be considered a requirement for these engines-especially in this heat and my driving style.
But, these are top shelf synthetics, designed to run better than anything else (I know there are some better oils than Triumph's Mobil 1, but personally I think Mobil 1 is so good that it doesn't make as much of a difference).
