I have a 2015 Street glide special and I was looking for oil for my new Harley . So I called several places and then i called Mobil 1 tech support and I spoke to a tech and the tech assured me that I would be very pleased with this oil . I also asked if i could run the oil in the transmission and primary . The tech checked and said yet . So I picked up the oil and changed the oil my self . I am pleased with Mobil 1 because i already run Mobil 1 in my Corvette . I will only need 1 oil only for ever thanks for the information and great product .
Great oil and runs cooler.

I ride a 2013 FXDC and have always used Mobile 1 V Twin 20w-50. This oil is an excellent product but I have decided to try Mobile 1 Racing 0w-50 (not the 4T). The reason for this is all HD`s Twin Cam engines run independent from the clutch or transmission just like a automobile engine without the liquid cooling, so why not take advantage of the "friction modifiers" that are added to the Mobile 1 Racing oil but not present in the Mobile 1 V Twin oil. The fact that you can run Mobile 1 V Twin 20w-50 in all three holes because you need some friction for the clutch to work properly has led me to try the Mobile1 Racing oil for my engine only. I still will be using the V Twin oil for the primary and transmission. Air cooled Twin Cams run hot. These "friction modifiers" should help keep wear and tear down inside my engine better than oil without them.
Please understand, I am not trying to start a debate here. All Mobile 1 products are of excellent quality and the only oil I will ever use. This is just a personal choice that I have decided to make.
Excellent Product

I decided to do my own oil change this year, after reading reviews, I chose Mobil 1 V-Twin 20-50. I must say it does wonders in quieting down the mechanicals and results in much easier starts. Very pleased with this product and will change one more time just before my ride to Sturgis this year! 2013 FLSTC.
Switched to Mobil 1 at first service!

I have a 2013 H-D Ultra Classic with the 103 V-Twin and switched to Mobil 1at the first 1000 mile service. I immediately notice a reduction in engine heat in this air cooled motor and also used on the transmission and primary. Neutral has never been easier and the transmission oil looks like it was never used. Mobil 1 is cheap insurance and I like the convenience of using one oil in "all 3 holes". I keep a spare quart on hand though my bike never needs topped off. I'm a believer and my much cooler bike agrees.
Best Oil Ever For VTwin

I have ran Mobil 1 20W50 in all my bikes. Makes engine run smoother, cooler and more power. Wont use anything but the best in my Ironhorse Slammer. Thanks Mobil 1!!!!

Switched over to this after initial 500 miles on my 2014 Harley Davidson Street Glide. Immediately noticed the engine ran quieter. Typically these push-rod motors have a lot of mechanical noise. It was noticeably quieter and ran smoother after I switched to the Mobil 1 V-Twin 20w50.
Also run it in the primary case.
