For example, the 10W-30 oil with thin out more quickly at a higher temperature compared to the 10W-40 oil. Single-Grade vs Multi-grade Oil Single-grade engine oils cannot use viscosity modifier additive and have 11 established viscosity grades out of which six are denoted with the letter “W”. There is no difference between 10W-30 and 10W-40 oil. However when the engine is hot, the 10W-40 oil is thicker than the 10W-30. This is why single-grade oils are very bad. Straight 30 weight oil is way too thick when cold to properly lubricate the engine.

For starters, in oil nomenclature, “W” does not stand for “Weight”. It stands for The difference between 10W-30 and a 10W-40 is the high temperature viscosity. 21 Feb 2019 what motor oil viscosity grades like 5W30, 15W40, 10W40 mean, this guide when choosing engine lubricants, but what do they mean and why do they A lubricant with a low viscosity grade will be more fluid, more liquid,  "The W means the oil meets specifications for viscosity at 0 F and is therefore suitable for Winter use" But, what are the viscosity specs at 0 F  exactly what Car & Motorcycle Engine Oil Grades / Viscosities actually mean: Cut Find out exactly what grades are, and what the W really stands for, plus much a monograde 40 to multigrade 0w-40, 5w-40, 10w-40, 15w-40 are the same  Running synthetic oil and need to top off with conventional oil? No problem, modern synthetic oils can be mixed with dino (conventional oil) without issue. Of   13 Nov 2017 We try to answer the commonest question – “Which Engine Oil should you use?”. a lot of confusion among bikers with respect to the different engine oil This article is prepared to make a layman understand what does 

2 Aug 2019 The average layperson might think that all motor oil is the same. Every oil container has a series of numbers on it with the letter “W” in the then you would want thicker oil in your engine, such as 15W40, 10W40, or 20W50.

Motor oil grades that contain the letter "W" indicate multigrade oil. These products contain a low-viscosity motor oil as well as various polymer additives. The additives have little effect at low temperatures, but cause the oil to thin down in hot conditions more slowly than usual. The number before the "W" indicates the oil's grade at 32 To be blunt about the subject, if a bottle of oil does not contain the following basic information then DO NOT buy it! Look for something that does! 1) The purpose for which it is intended (i.e. Motor oil, Gear oil etc) 2) The viscosity (i.e. 10w40, 5w30 etc for Motor oils and 80w90, 75w90, etc for Gear oils) SAE J306 defines the gear oil grades differently, and therefore higher number oils, like 75W-140, does not imply it is more viscous than motor oil because they are on different scales! Polytron MTC is premixed with 10W-30; one of the most common motor oil to mix efficiently with your main oil. We also produces Full-synthetic and Semi-synthetic In 10W/40 motor oil, the W stands for weight, right? Wrong. It stands for Winter. A vehicle's oil has to be thick, but not too thick. It is important that in the winter, the oil be thin enough to allow for the engine to start. But when the engine is warm, the oil must be thick enough to lubricate properly. That's where the numbers come into play. Motor oil, like so many other products we all use today, has come so far from what it used to be in terms of technological advancement. Nowadays, there are a dizzying array of products, types, styles, weights, and formulations of motor oil to choose from, that it can be difficult to know exactly what each one is intended for and what exactly it’s supposed to do. The oil in your car is pumped through the engine when it's running, protecting it from mechanical wear. Oil is sold in a variety of "weights," usually expressed as xWy. The difference between 10W30 and 10W40 oil isn't too big, but to understand it, you'll have to understand a few basic things about For example, the 10W-30 oil with thin out more quickly at a higher temperature compared to the 10W-40 oil. Single-Grade vs Multi-grade Oil Single-grade engine oils cannot use viscosity modifier additive and have 11 established viscosity grades out of which six are denoted with the letter “W”.

In a 10w-40 for example the 10w bit (W = winter, not weight or watt or anything else for that matter) simply means that the oil must have a certain maximum viscosity

Synthetic technology motor oil – Helps to keep engines clean and running efficiently. Makes use of both synthetic and mineral base stocks to achieve higher  

You also need to pay attention to the numbers on the label of the motor oil. You might see something like “10W30” or “5W20” and wonder what the heck they mean. Even if you have your oil changed by a professional, they normally put a sticker on your windshield which indicates the numbers of the oil they used in your vehicle. IT does not mean winter or weight. It is just a freaking letter. And to all thinking that in a 10w30 that the engine oil is a 10 weight when cold and a thicker weight weight warm need to go back to highschool. Since when is oil thinner when cold. Again, W is not for winter or weight. It is just a letter.

31 Aug 2014 15W40 means that at cold temperatures the oil has the same viscosity as temperature, with a appropriate pressure to each part of the engine. the engineers of total lubrifiants design products with sustainable development in mind in this means is that if the engine is to perform at its best, the oil must be able to retain its viscosity total QuartZ 7000 10W-40 ensures that your engine stays clean by Do not use where a fluorescent green colour mineral fluid is. 18 Mar 2019 SAE-30 is single-viscosity or mono-grade engine oil. However What does 10W -40 mean? This means, 10W-40 oil can flow at 10 degrees Celsius. CarBikeTech is a technical blog with experience of over 20 years in the  The viscosity grade of a motor oil provides information on the oil's resistance to flow in How do I know what the right viscosity grade is for my vehicle? choose a motor oil with a high viscosity grade that is not marked “W”, meaning SAE 8, 12, 16, purchased motor oils, you'll see values such as 5W30, 15W40, or 10W40. 1 Jan 2009 I have a 1993 Ford van with a 4.9-liter 6-cylinder engine. The owner's manual recommends 10w-30 SG/CD, which I could not find. What do all  What does 10W40 mean? Engine oil with class 10W40 is a multigrade oil with good flow properties at cold and warm
