If your like me and love the wind in your hair and sometimes bugs in your face, this is top tier for your bike, always remember most bikes are wet clutch, meaning your oil is in your transmission. You stick with this and you will be riding for many years to come

Great oil. Can feel the difference shifting.

I use this oil in my airplane It has a 4 cycle 100 HP engine With a gear reduction

This Mobil 1 is a great oil for a lot of street bikes including 4 stroke sport bikes for a reasonable price. It doesn't have a flashy European name, but it is a really good, full synthetic product that will provide the same protection as the cooler sounding options costing significantly more.

Great overall. Shifting is smoother than ever. Engine rev is smooth.

I use this oil in my Suzuki SV650S, Honda Shadow Aero 750, and my Suzuki DR200SE. They all call for 10w40 and this oil works very well. All three of my bikes shift well and run a bit cooler and quieter running this oil. It's a bit on the expensive side but I like the piece of mind I have while running it. It's last a pretty good while too. You can ride three thousand miles or even four to all the up to five thousand miles before changing.

Exactly what I needed. Delivered quickly.

I've ran synthetics in other bikes but recently switched to this from the standard GN4 Honda recommds for my 2006 ST1300. Let me say, my bike was ANGRY before putting in mobil 1 racing 4T. The bike shifts smoother and I can literally feel the added difference in power now. I will be using this oil exclusively going forward. Love that it can be purchased locally as well.

The perfect oil for my 2013 Yamaha FZ1. Smooth shifts and ultimate protection for 3-season riding. I have no concern with taking this oil to 12,500 RPM. Bottom-line? Mobil 1 4T is simply the best.

Awesome oil as usual. Horrible shipping as usual!

This oil is endorsed by Triumph Motorcycles and is the only oil for the model I have they say to use.

Great motor oil for our Chinese ATV's. Synthetic motor oil handles the heat of the air cooled engines without breaking down.

I always use quality synthetic oils. Small engines need synthetic oil, most small engines have no cooling fans to speak of, syntheyic oils help dissipate heat helping engines last longer.

I use this oil on my Suzuki Bandit and in the primary on my Harley Davidson touring bike. Works great in both. I use other Mobile 1 Synthetic oils in all my vehicles. Never had an oil related issue.

The engine seems to run a bit quiter. Shifts are a bit smoother. All good I would say. I used the Honda gn4 conventional oil previously. Seems like an improvement .... at least to my ears ! I guess time will tell.

I have 90,000 miles on my 2015 Yamaha FJR1300 using this oil. It uses no oil between 6,000 - 8,000 mile oil changes. I have never had any motor issues.

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.

I have been using this and this only for the past 7 years in both my Gold Wing 1500 and my present Gold Wing 1800 and have no problems what so ever. My motorcycle always runs cool and shifts perfectly. I recommend this for use in any cruising motorcycle.
