Rated 5 out of 5 by from Great product I used to order Amsoil MC Oil for my motorbikes, noticed it was going up in price slowly over the years so I went to Pep Boys during a sale and found this was much cheaper so I switched, Bikes run great, right now I have an HD VRSCA and Triumph Scrambler and they shift and stay cool just as well as the more expensive Amsoil and Mobil 1 is easier to get locally etc...

Rated 5 out of 5 by from Used in a Peerless VST Hydrostat Lawn tractor This is an older Murray Tractor with a VST unit that I rebuilt because of internal loose hardware. These units run very hot and there is a consensus of using 20W50 vs their expensive hydrostat mystery oil in the pump. Many have had success with this fluid. Unit seems very smooth and noiseless after 10 hours of use. While flat terrain performance is maybe a bit better than the old fill, Performance on steeper hills is excellent, the old stuff seemed to struggle even when brand new. Considering the old stuff was 15 years old, This oil will hopefully last the life of the unit.

Rated 5 out of 5 by from Best V-Twin Oil I've Ever Used! I have a 2004 Yamaha Road Star Midnight Silverado XV1700 V-Twin. I had used a couple of other brands (brand "C" and brand "RP"). They did the job, but I wasn't 100% happy with their performance. I use Mobil 1 Extended Life oil in my GMC truck, so I wanted to try Mobil 1 in the bike. I can honestly say that I'm now 100% happy with my oil's performance. On start-up, the engine is quieter. On the road, the engine runs cooler, quieter, and smoother. The transmission shifts smoother, too. Upon changing the oil, I even found the used Mobil 1 to be cleaner than the other brands I'd used when changing them. Overall, this is, in my opinion, the best oil you can use in a V-Twin engine.

Rated 5 out of 5 by from I switched! I used to use a traditional 20W50 oil in my 2007 FLTR. I tried Mobil 1 V-Twin after reading about it in one of the motorcycle magazines I subscribe to. My engine now runs cooler and quieter, plus it seems to run smoother. Now I only have to change the oil once or twice a year. Just wish it came in a gallon size.

Rated 5 out of 5 by from Best lube for all three holes! I put the 20W-50 in the primary, tranny and oil bag and the bike shifts super smooth and runs like a champ! I won't use any other oil for my Harley!

Rated 5 out of 5 by from excellent motorcycle lubricant I believe this is one of if not the best v-twin synthetic motorcycle oil on the market. It has served me well for over 150,000 miles. It is probably the same oil that Harley uses and sells but I have been unable to verify.

Rated 4 out of 5 by from The Least of Evils Although Mobil has changed their formula for the worse, this is still the best oil you can get for your motorcycle. With an air-cooled engine, you need an oil that will take severe temperature abuse and that has a high shear strength. Mobil V-Twin still does this well. Just compare the used oil to used conventional oil. Also, all other motorcycle oils that you see at retail stores (except Amsoil and RedLine, which are not generally sold at retail), are 100% petroleum based (group III basestocks). They may have "similar" performance characteristics initially, but because they have so many viscosity modifiers and additives, break down very, very quickly. I recommend doing a little research on oil, not just what the oil companies say. Just take every piece of information with a grain of salt. If you are going to fork over the big bucks for a motorcycle, doing a little research to protect your investment is critical. Oil is the lifeblood of your engine, and inferior lubrication is the ONLY factor that will determine your engine's longevity, provided you keep it in tune and don't get hit by a semi.

Rated 4 out of 5 by from This Oil is the Best Yet ................ 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 .

Rated 4 out of 5 by from I made a change 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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!!!!

Rated 5 out of 5 by from My Harley Engine runs quieter 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.
