FAQs

How is Mobil 1™ V-Twin 20W-50 motorcycle oil different from Mobil 1™ for passenger cars?

Mobil 1™ V‐Twin 20W‐50 fully synthetic motorcycle oil is designed for air‐cooled, large‐displacement bikes. Because of their design, these engines can generate very high localized oil temperatures and high overall bulk‐oil temperatures. A typical air‐cooled V‐twin's rear cylinder gets a lot hotter than the front cylinder – it's a matter of airflow. When it's hot out and you're stuck in traffic, the oil temperature in a bike climbs rapidly. Above about 250 degrees Fahrenheit, conventional motor oil is going to break down. Mobil 1 V‐Twin 20W‐50 fully synthetic motorcycle oil is good to above 300 degrees Fahrenheit. Like Mobil 1 Racing™ 4T 10W‐40, Mobil 1 V‐Twin motorcycle oil has high levels of phosphorus/zinc and the same high‐temperature detergent technology for superior wear protection and engine cleanliness, even at elevated oil temperatures. With Mobil 1 V‐Twin motorcycle oil, you can go the full length of the manufacturer's recommended oil change intervals with ease.

What are the overall advantages of Mobil 1™ motorcycle oils?

In addition to the overall benefits of high‐temperature stability and low volatility/low oil consumption, Mobil 1 synthetic motorcycle oils also offer superior anti‐corrosion performance compared to conventional motor oil, which is important in many parts of the country where bikes may sit in garages for several months of the year. Compared to conventional oils, Mobil 1 motorcycle oils provide superior wear and high‐temperature protection, and promote engine cleanliness and lower oil consumption. Once you get beyond these general advantages, you have to consider individual motorcycle oils to understand the benefits of each.

So how are Mobil 1 oils for motorcycles different from Mobil 1™ synthetic motor oil for passenger cars?

It's a little hard to generalize about the difference between Mobil 1 passenger‐car motor oils and Mobil 1™ motorcycle oils. That's because not all viscosities of Mobil 1 passenger‐car oils have the same levels of zinc and phosphorus, and there are even greater differences between the two Mobil 1 motorcycle oils.

In general, Mobil 1 motorcycle oils have additive packages formulated for use in both motorcycle engine and transmission operation.
For passenger vehicles, fuel economy and emission system protection are higher priorities. These require low phosphorus systems and the use of friction modifiers.
Motorcycle oils do not require friction modifiers for fuel economy and for better clutch friction less/no friction modifier is optimum.
Motorcycle oils allow the use of higher levels of anti‐wear additives such as ZDDP (phosphorous).

Plus there are the overall benefits of Mobil 1 synthetic oil compared to those of conventional motor oils, whether they be for passenger cars or motorcycles:

Superior long‐term engine protection
Superior high‐temperature stability
Excellent low‐temperature starting
Outstanding engine performance
Low volatility/low oil consumption

Rated 3 out of 5 by WideGlide from Runs hotter and louder valve train I've been using this oil for about 1200 miles in my twin cam 96ci Harley engine. Its definitely way louder than other vtwin oils as far as valve noise and lately its been running hotter than the last 2 oils I used. It is cheaper though. A third the price of amsoil.

Rated 5 out of 5 by ahill2 from Oil for my 2004 Harley Davidson Fatboy I have been using Mobil 1 for many years, and it just works, period. I have ridden my bike to Sturgis South Dakota, temps can get Hot running at highway speeds and it has never given me reasons to worry. For me, Mobil 1 is all I use.

Rated 5 out of 5 by Trabs from Incredible oil I have used synthetic oil before in my motorcycle and cars but never used Mobil 1... l finally gave it a chance and put it in my 2008 Suzuki c50 and I am blown away..I noticed how smooth the shifting is compared to the other oil that was in the bike..plus on the freeway it seemed like the motor was working so hard around 80 but since I put Mobil 1 in my bike the motor seems like it got an extra gear..it blows my mind because now I don’t even here the motor and I looked down and was doing 85 without any struggles.. what I’m telling you is this motor oil is a miracle oil..please do yourself and your bike a favor and get up and go do a oil change on your bike right now and use Mobil 1.. thanks I will buy nothing else.. going to put it in my car this weekend..#bestoil

Rated 5 out of 5 by Jim63 from Quiets the valve train Switched to Mobil 1 from Amsoil. Noticed an immediate reduction in valve train noise. Engine runs cooler and quieter, like new performance at 26,000 miles many of which were in extremely hot weather. (air cooled Harley Davidson). A buddy who runs Mobil 1 had his engine size increased from 88 c.i. To 95 c.i. The mechanic remarked that his pistons and cylinders were in remarkable condition. This was on a Harley with 85,000 miles. I will use nothing else.

Rated 5 out of 5 by luv2fix 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 RoadAce 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 Moonmanvt 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 4 out of 5 by jones 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 DynaRider 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 dlust 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 Helion 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 CycleRider 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.
