Yamaha Yamalube 10W-40 Motorsports AP (All Purpose) Engine Oil- 1 Gallon, #LUB-10W40-AP-04

This is Yamaha OEM oil. I have been using it in my Yamaha ATVs for years. Have never had any oil related engine issues. I will continue to use this oil in the future.

regular purchaser of this oil. have used it with good results in dirt bikes and atv's. works with wet clutches and sometimes is a good price.

I have a 2007 Yamaha V Star Silverado 1100. I bought it used with 17k miles on the odometer and it ran fine. Not knowing what the maintenance was like from the previous owner I decided to do a full tune up including oil and filter change, final drive oil change, new air filter and spark plugs, valve adjustment and carburetor sync; it made a huge difference in the way the bike felt, sounded and not to mention the ride. For that first oil change I used the Motul 10W-40. With time my clutch started slipping no matter how well I adjusted it (top and bottom adjustments). I don't ride the clutch or do any weird driving to have the clutch slip with such low mileage. Asking around a friend told me that some older Japanese bikes won't take well synthetic oil and to look into changing the oil with original Yamalube to see if that would fix the issue. To make a long story short I ordered this Yamalube and a new filter and once I received both went on to changing the oil. Incredibly enough not only did the clutch slip stop but from the first start the engine sounded different; way quieter (engine internals very smooth), exhaust sounds deeper now, it has more power and you can rev the engine up in normal driving with noticeable less vibration. I am very happy with this product, this will be the only engine oil I will use from now on in my motorcycle. I've put on at least 3k miles since the oil change and haven't noticed any down grade in performance or sound. Great product, highly recommended.

I’ve been using Yamalube in my 2015 FJR1300 since new. Never encountered any engine or transmission problems. Good product!

Fantastic

There are some people that will fight about which is the right or proper oil for your car, truck, boat, or motorcycle. The best oil for a motor is any new oil or full oil, meaning do change often and ensure that it is at proper level. After that it is best practice to use the correct oil for your motor, there are many labels/ certifications for each motor manufacturer. Some oil brands will pay to have those on their box or jug, some will not. with that said, this oil is fine and will work in many motorcycles that have WET Clutches. I have tested various brands of oil and this one seems to be a very generic Motorcycle oil, there is nothing special about it except the Yamaha name. Pros: 1. its a MC oil 2. it has Yamaha as its brand Cons: 1. Cost make it similar to brands Synthetic (full or semi (blended) oils) 2. you can find the Yamaha Full synthetic (same 10w-40) on other sites for the same price (or within $2) 3. Additive package is very much average (high Calcium and low Magnesium for cleaners, and (low MolyB (makes sense in a WET Clutch), average Zinc, and Phosphorus for anti-wear) Overall, I only used this oil during Break-in of a new bike, already have Yamaha Full Synthetic in there now and have a different brand that will be used during next oil change. Check out Castrol 4T, Amsoil Metric MC Oil, or Shell Rotella (5w-40 or 15w-40). The shell rotellas (used in other motors and MCs of mine) have similar additive packages (and are half the price). But as always use the oil that best suits you, your budget, riding style, and most importantly Motor.

Probably the best atv oil out there. 4400 miles so far with no engine issues yet.

Yamaha 4-stroke oil is an excellent choice for my Grizzly 700! It provides smooth, reliable performance and keeps the engine running clean and efficient. The oil is formulated to handle the demands of a powerful 4-stroke engine, and I've noticed less engine noise and better overall performance since switching to it. It also offers great protection against wear and tear, which is important for the longevity of my ATV. Highly recommend this oil for anyone looking to keep their Grizzly 700 or any Yamaha 4-stroke engine running smoothly!
