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-30This oil has a weight of SAE 10W-30, meaning it has an SAE viscosity rating of 10 in cold temperatures and a rating of 30 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.High Mileage OilThis oil is primarily designed for use in high-mileage cars and trucks, including both older vehicles and new vehicles that see heavy long-distance use. Extra additives are included to minimize compression loss, and to condition rubber seals and gaskets to prevent fluid leakage in older or high-mileage vehicles.

## Questions & Answers

**Q: Will this work for everyone ?**
A: Not every motor oil is suitable for every type of engine.  Castrol always recommends following the guidelines of the original engine manufacturer for the recommended grade and API specific to your application. This information can be found in the vehicles owner’s manual or by contacting the manufacturer directly.

When deciding on a formulation, you need to take into consideration factors such as, what type of conditions do you drive in?  What kind of protection are you looking for?  What is the manufacturer recommending?

**Q: Would anyone recommend this oil for a lawn mower with 190cc??!? I want the best oil for my 4 cycle**
A: I would use Castrol but look in your manual or online to see what weight oil your mower requires.

**Q: is this a high detergent oil?**
A: Yes it is works for me

**Q: Would anyone recommend this in a lawnmower with 190cc?? I want the best oil for my 4 cycles?!?**
A: Go for it. It has worked out for my lawnmower and my 4 Cycle-Pocket Bike motorcycle. Theses engines are built within the same 4-cycle architectures, so go for it without a second though. I had only trusted only within the Castrol protections for 2 years anyway. (The higher number than the W30 is, the thicker the motor oil will get, in which means that a higher revving can only melt those types of motor oil. A lawnmower is not a high aggressive engine unlike a motorcycle nor a car* So head on over no lower than a 10 "W30", or you won't be getting of any proper PISTON protection.) Good Luck* In fact... My 125CC had asked me to use a 10 W40... Try to go accordingly by your manual, either way; these oils will work anyways. Just don't use any of the 10 W20 or lower, those oils are too light to serve no protection.)
