Mobil 1 Racing 4T 10W-40 Motorcycle Oil, 1-Quart

Mobil 1 Racing 4T 10W-40 is designed primarily for on-road, high-performance, 4-cycle sport bikes; however, it may be used in other types of on and off-road 4-cycle motorcycles especially where a 10W-40 viscosity grade is specified. Mobil 1 Racing 4T 10W-40 is recommended for 4-cycle motorcycles which specify the use a 10W-40 engine oil. This oil will help provide excellent performance in motorcycle engines that are designed with a common engine/transmission lubrication system or where the engine lubrication system is separate from the transmission system. In the case of the latter, follow the manufacturer's recommendation for the type of fluid to be used in the transmission. Mobil 1 Racing 4T 10W-40 engine oil is designed to help provide the proper frictional characteristics necessary for wet-clutch common engine/transmission systems. It has been fully tested, both on laboratory dynamometers and in the field, to help provide optimum horsepower and acceleration. The unique, synthetic structure of the Mobil 1 motorcycle oil formulations enables them to offer advantages beyond conventional motorcycle oils of similar viscosities. For example, base oils become lighter in viscosity as temperature increase. This characteristic forces manufacturers of oils to use thickeners which will help the oil maintain its viscosity as the temperature increases. These thickeners, however, can shear down and lose their thickening capacity in an operating engine or transmission. Synthetic fluids do not require as much thickener to achieve a multigrade viscosity rating and, in some cases, do not require any thickener. As a result, synthetic formulations tend to be very shear stable and thus, provide a solid, protective oil film for engine bearings, piston rings, transmission gears and other critical engine parts.

Mobil 1 Racing 4T 10W-40 Motorcycle Oil, 1-Quart is rated 4.9 out of 5 by 19.
Rated 5 out of 5 by from Great oil. I've been using Mobil 1 in my cars for years now with excellent results. Now using it in motorcycle, fantastic shifts and seems I will have excellent results with the 4T blend just as I have with automotive blends. Got a Great Deal on sale at Pep Boys!

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 5 out of 5 by from superior engine protection I can race my motorcycle with piece of mind when i use mobil 1 motor oil,i have had oil analysis performed on this oil with results far above the competition brands,so needless to say i use this oil every motor I own,It would be nice if my Pep Boys store would increase its inventory on this oil,sometimes i have to get the remaining oil i need at Wallmart..

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 Product I used 10w-40 spec oil to get better weather (in Midwest) advantage on my v-twin engine is liquid cooled. Engine runs much smoother cannot say if it cooler as it is liquid cooled. Will know more when run in proper summer heat. The summary section says that it can be used for any 4 cycle engine so can be used in cruisers... so v-twin people worried that you have to use that kind mobile oil just read the detailed description. Safe Riding

Rated 5 out of 5 by from Mobile Oil Everyone has their own favorites when it comes to motor oil but for me this is the ONE and ONLY motor oil for my ride. Little more $ than the run of the mill oil but it is well worth the cost. Whether you are astride a big cruiser or setting a sports bike this is the oil you really should take a look at.

Rated 5 out of 5 by from Engine runs quieter & shifts smoother Changed both of my high-performance sport bikes to Mobil 1 Racing 4T 10w40. Noticed the engines ran smoother & quieter. Also seems like the transmissions shift smoother. Great product. Only oil I'll use!

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 Mobil1 10w-40 Racing 4t Motorcycle Oil I changed the oil & filter and managed to take a ride for about 200 miles last weekend. The bike responded great and the gears changed like butter for me. I'll probably stick with this oil for a long time. Plus the price was great at Pep Boys.
