The 10W-40 stuff HAS to have enough VI to cover a 30 point weight spread; the 10W-30, a more manageable 20 points. Between a 10W-30 and 10W-40, 10W30 motor oil would run smoother in colder climates while a 10W40 would be more effective in preventing engine wear and tear in warmer temperatures.
However, you dont want to use it if you live in hot climates or it is the What weight oil should I use in my generator? You can find 10W-40 auto oil with an API SG though. So, you can have 'thin' and 'thick' oil within the same oil grade - ie, Havoline 5W-30 is 9.7 cst@100C; while Maxlife 5W-30 is 11.5 cst@100C. The Society of Automotive Engineers (SAE) has established a numerical code system for grading motor oils according to their viscosity characteristics known as SAE J300.The original viscosity grades were all mono-grades, e.g. You can use 10w40 motor oil instead of 15w40 motor oil, but you have to know that your manufacturer should always use the recommended oil. Can I use 10w40 instead of 10w30 in my lawn mower? The synthetic engine will be fine as long as it is fully synthetic. With temperatures going down to 20F a 10W oil will not be an issue.
But when the engine reaches the operating temperature (100C), 10W30 oil will be much thinner. Honda K20 engine modifications and differences 1. The only difference between 10w30 and 10w40 oil is their thickness at engine operating (hot) temperatures. You will find that 10W30 is used more often than 10W40. What Happens If I Put 10w40 Instead Of 10w30? If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.
Beside above, is it bad to mix 5w30 with 5w40? Obviously, both 10w40 and 10w30 are the most common oils used for car engines. The first numbers 10W and 5W are referring to viscosity at cold so that the lower the number is the thinner the oil is at cold and vice versa. The engine gets warm in the summer. I had the quietest shifting with the 20w-50w; but in the cold morning starts, the starter didn't like that thick of an oil.
Yes, actual oil viscosity decreases with oil temperature and your oil pressure readings don't surprise me.
Some cars may allow a little flexibility for motor oil, but it is best to check with your car mechanic before making the switch. The best conventional 5W-30 is Havoline Energy. On the other hand, the second portion of the grade number describes the thickness of the oil.

If you were to use 10W-30 instead of 5W-30, the engine would be slightly less protected against wear during startup and colder temperatures. As the first portion of the grade number describes thinness, we can see, 5W30 is thinner than 10W40. For example, if youre already using 10W-40 oil, 15W-40 will be super bad for you. But be aware that as it's a thinner oil, it might not lubricate engine parts as well as 10W-40 as temperatures continue to increase. Using an oil with a low viscosity can lead to excessive metal to metal contact between moving parts. So, for example, a 5W-40 will be thinner than a 10W-30 in low temperatures.

The 5w30 motor oil and 10w30 motor oil are both thirty-weight oils, and they have the same thickness in your vehicle if it is at operating temperature. The 5w30 motor oil is better because this oil will thicken less if it is cold. However, there is eighty percent wear that can occur upon startup. The thin oil will get to the top end faster. Above 32F, use SAE 30. Gear Oil 80W-90 is a premium mineral automotive gear oil manufactured with modern extreme pressure additives and friction modifiers, meeting the requirements of API GL-5/6 and MT-1, as well as many other manufacturer specifications. Although you cant interchange these two oils, you need to understand their difference to know the best applications. If the manual says to use synthetic oil, do so. This is because all oils thin when heated, so to get the right film thickness at operating temperatures oil manufacturers The oils MAY carry a higher API Rating BUT, they MUST then have the JASO MA or Balancer shafts, a more rigid crankshaft, high compression pistons (CR = 11.5), reinforced connecting rods are installed into the cylinder block, and dual valve springs, dynamic camshafts, 20W-50 . it will over a 15w40.
