Types of motor oil include conventional, synthetic, diesel, bio-based, hybrid (blends of conventional and synthetic), and recycled oils. Motor oil varies in weight and viscosity, as well as additives that some manufacturers add to the oil during the refining process. A numerical code system created by the Society of Automotive Engineers (SAE) grades motor oils according to viscosity--the higher the number between 0 and 60, the more viscous (thicker) the oil is. Most consumer motor oils are graded by two numbers, with the first number indicating cold weather (Winter or "W") performance.SAE 10W-40This oil has a weight of SAE 10W-40, meaning it has an SAE viscosity rating of 10 in cold temperatures and a rating of 40 at normal operating temperature. Always check your vehicle's owner's manual to verify that this is the correct weight of motor oil for your vehicle.Conventional Motor OilThis oil is a conventional motor oil, meaning it is refined from crude oil or petroleum products. Conventional motor oils may or may not have additives included after refining. Conventional motor oils are more versatile than synthetic or hybrid motor oils, because they are suitable for use with nearly all types of modern vehicle engines, from cars and trucks to motorcycles, ATVs, farm equipment, and more.Racing OilRacing oils are designed for track cars and other types of high-compression vehicles intended for motorsports competition. They contain particular additives for increased engine horsepower and reduced friction on metal parts, and provide special protection for engines with high compression or higher horsepower. Racing oils usually include fewer detergents than regular conventional motor oils. Please note that many, if not all, oils labelled as racing oils are not street legal, and it is not recommended to put racing oil in a conventional passenger vehicle. Make sure to double-check the product label as well as the specifications of your vehicle to ensure proper usage.

Review: A Great Motorcycle Synthetic Oil - 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 desertcart is easy and the price was the lowest I've seen anywhere. It's a good value for the money.
Review: Fantastic Oil - 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.

## Questions & Answers

**Q: Would this be a good oil for an engine that uses a slipper clutch? 
Kawai Ninja ZX10R**
A: I use this oil in my 2014 Ducati Diavel, which has a slipper clutch.  If I purposely over-rev it on a downshift, the slipper clutch slips as advertised.

**Q: Will this work on 2006 fz6?**
A: This oil performs very well in my '99 Valkyrie.  Check your owners manual for the FZ6 for the oil classification you need to run.  If the Mobil 1 10W-40 matches the spec then you are good to go.

**Q: What's the difference between this and the Mobil 1 103436 oil?**
A: Nothing. Same oil by another number.

**Q: Is this synthetic or conventional? picture says synthetic but description cleary states -this oil is a conventional motor oil, meaning it is refined**
A: I've only ever seen it sold synthetic. While conventional may be more versatile, synthetic is usually more durable and higher quality. I use this in my 2014 KX450F and it is by far the best oil I've ever used.
