Mobil 1 98JA11 10W-40 Racing 4T Motorcycle Oil for Sport Bikes - 1 Quart (Pack of 6)

In my opinion, it's the best synthetic oil available for motorcycles. I've used it in my Triumphs, my Royal Enfield, my Suzuki TL1000S, and others. It doesn't have any additives that interfere with wet plate clutch operation. I've never had any engine problems using this oil. Buying from Amazon is easy and the price was the lowest I've seen anywhere. It's a good value for the money.

Bought my Suzuki Bandit 1250 in November of 2007. Other than the first oil change that was done by the dealership, I have only used Mobil 1 10W-40 Racing T in my bike and it is still going strong 18 years and 33,000 miles later. Definitely worth the price to use 100% synthetic oil that is designed for your type of bike.

This is great oil for high rpm riding and racing, but it is NOT for daily street use.. the oil broke down fairly quickly for what u would expect.. i would not leave this in my motorcycle past 600 miles, you can definitely feel the friction on metal components once oil is going bad .. switched to Royal Purple w/o flushing and its been great since

Used it many times. Makes things work better and improved mpg.

Bought my R3 used, and the previous owner was using regular oil. Bike was a little bit jumpy when shifting. Purchased this oil, along with OEM Yamaha filters. Wow. What a huge difference. My bike sounds and feels so much happier now! Shifting gears is butter smooth, I have much more confidence in my bike now. Could not recommend enough.

Mobile 1 products are exceptionally good.

Seems to do what it claims,but Mobil 1 I use in my car so I trust the brand.

Took a while to find what works for a 2014+ BMW R1200RT (water cooled). 4T is the answer, any synthetic 4T. Book calls for 5w-40. I live in West Texas, the 10w-40 works great here - you should probably find 5W-40 4T synthetic if you live in the land of cold. I could tell difference in gear shift smoothness (wet heads crash gears) immediately. As for life and mileage - I'm not an oil lab - oil changed every 4,000 miles or less. Duh.

Excellent oil all I will use in my wing. Usually can pick it up at Walmart but not sure if you still can in Canada burp the fortunately found it on Amazon few bucks more but make my bike happy.

Arrived promptly, no issues. I am not an engineer so I can’t comment on the differences this oil has over other brands. The reputation of Mobile One is very good.
