Full synthetic offering outstanding protection

Mobil 1™ V-Twin 20W-50 synthetic motorcycle oil is formulated to help offer outstanding protection in four-cycle, V-Twin type engines – particularly those that are air-cooled and tend to run hotter than other types of engines.

Mobil 1 V-Twin 20W-50 engine oil is designed to help provide the proper frictional characteristics necessary for wet-clutch common engine/transmission systems.

The unique, synthetic structure of the Mobil 1™ motorcycle oil formulations offers advantages beyond conventional motorcycle oils of similar viscosities.

Please reference our Mobil 1™ Product Guide for a quick look at specifications including zinc and phosphorus, as well as manufacturer approvals for Mobil 1 motor oils.

Features and benefits

  • Superb shear stability can help resist viscosity shear down in high-performance engines and transmissions
  • Exceptional thermal stability can help resist oxidation and high-temperature degradation
  • Outstanding protection against wear of engine and transmission components
  • Enhanced lubrication can help maintain maximum power and acceleration over the life of the engine
  • Optimized wet-clutch performance
  • Excellent low-temperature flow characteristics can help minimize engine wear during startup

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 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 Great oil worth the extra cost I switched from Valvoline synthetic to Mobile 1 in my Triumph Speed Triple. There is a noticeable difference in clutch smoothness and engine performance. My bike runs much smoother and quieter than before, this is especially true during the initial warm-up procedure. Mobile 1 stays much cleaner than any other oil I have used in the bike. I've found that after a year the oil is still good, though I replace my oil once a year and use a K&N oil filter (I put about 3,000 miles a year on my Triumph). I'm going to stick with this oil, my bike loves it!

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 5 out of 5 by from Great Oil for ATVs!! I used to run Shell Rotella in my Arctic Cat 500 and it worked but I decided to try Mobil 4T after a friend tried it and said he liked it better the the Shell. Well after on weekend of riding I was pleasantly surprised with this 4T oil. What I noticed was better wet clutch performance, less noise from the transmission gears and also the oil stays cleaner longer then the Shell Rotella. I will continue to use this oil for sure.

Rated 5 out of 5 by from Great oil for my 93 Honda 300 Fourtrax Better easier start up, more performance, smoother shifting, great power, before the clutch was slipping and I had to baby it to get it to pull out, but now I can hook up to a small trailer with garden supplies and pull it fine, or go on the trail and go slow and easy. Great product thanks guys/gals. :) You hit a home run.

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.
