Hey Bob, been using it in my 86 since 95. When I freshened up the top end after 33K, had absolutely no wear.I will keep using it.And those myths about leaks ? I’ve had no issues.That’s my .02

Thanks Don, I've been using it in a 89" stroker Evo for over a year now without issue as well. I should have been clearer about the application.. I'm wanting to use it on a TC 103" motor..

I would think you’d have the same positive results.

I ran Mobil Syn 15/50 in my 80 cu in. EVO for a couple years during a time when I was riding the bike to work everyday and putting approx. 450-500 mi per week on her. I wanted to take advantage of a longer oil change interval. It tended to be difficult to find as a good price and I did notice the mythical "Seeping" happening. Eventually went back to Castrol 25/50 and change oil/filter every 2500-3000 mi. Easy to find where I am, less expensive...(even given the shorter interval), and no mythical seeping.

Been using Mobil 1 15w 50 in my Twin Cam 2007 Street Glide for years! It has a great additive package, better than most so-called "motorcycle oils. I buy the 5 qt. jug at Walmart for $23.88, then Mobil has a $15 rebate, which means I get 5 qts. of oil for less than $2 a qt. I think you'll be very pleased with using it.

Shears easily. To a 30wt at that. In a sporty. Lot more where that came from too.
Maybe if you baby it. Stock? Performance cams? Cams and lifters are where wear happens first.
