would 20w60 penrite mineral oil for diesel be ok for harley twincam 103 with 20000k s[IMG]http://i1064.photobucket.com/

try Penrite ENDURO

What part of the country are you ?
My opinion is the 20w60 Penrite would be fine, and I have used it in a 1200 Buell, and a TC.

D'racer, would you say the Enduro 25w70 would be a bit on the thick side for cooler climates ?

 Thanks speedzter got your crankcase and crankshaft back yet oh i am down southcoast tuross head nsw

they do not hold enough oil  on board less than 3 ltrs esp on the under the engine sump models the oil gets very hot & down spec, drain when her  hot & you will see

 Penrite HPR Diesel 20w - 60w was recommended to me by local harley/trumpy workshop for my 2009 FXST.        I live up north though.

20w-60 diesel is perfect for use in evo and twin cams provided you only want them to last to in excess of 200.000 klms trouble free.............it's a long term marriage made in heaven

has anybody tried this in a sporty?

T1

I think a Buell is pretty close to a Sporty !

 Hey t1 iam running penrite 20/50 mineral for run in on mine will change back to ams at 1000klm check out penrites site good info on there

T1, I've run Penrite in all sorts of bikes/cars for years. I normally use HPR 10w50 gas semi Syn' in the twin Cam and the KTM 950.
It's easier to find out in the country, and a side benefit it is cheaper.
I'm sure HD oil is perfectly fine, but I've never used it, so can't compare.
