What is SAE 40 used for?
SAE 40 API SN /SM/SL is intended for the lubrication of gasoline engines for passenger cars, commercial vehicles and farm equipment as well as diesel engines for commercial vehicles and contractor equipment. It can also be used in gear and hydraulic applications if the builder approves the use of engine oils.
Is SAE 40 the same as 10W40?
High Temperature Viscosity This is often regarded as the engine’s operating temperature. This means that at 100oC, 10W30 engine oil has the viscosity of an SAE 30 single grade oil, and 10W40 oil has SAE 40 viscosity. 10W40 oil has a higher viscosity, retaining more thickness than 10W30 as the temperature rises.
Is SAE 40 the same as 15W40?
15W40 means that at cold temperatures the oil has the same viscosity as SAE 15W oil. At high temperatures it has the same viscosity as SAE 40 oil. This means that they are “winter” viscosity, for use at lower temperatures. The viscosity of a liquid is its resistance to flow.
Which is better 10w 40 or 15W40?
A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures. Hence, a car will start with fewer cranks when holding oil of a lower winter weight. 10W40 oil will perform cold starts better than 15W40 oil.
Can I mix 10W40 with 10W30?
yes you can mix 10W30 with 10W40 as long as the engine will work with both 10W30 and 10W40. In certain high performance engines the 40 could be too thick in certain engines. Most of todays engines use much lighter oils to save on fuel economy and due to engine specifications.
Can I put 5W-40 oil instead of 5w30?
There’s not going to be much functional difference between a 5w-30 and 5w-40 as there’s a lot of functional overlap in the recommendations. The lower weight might yield better efficiency under light load operating conditions, but higher weight might yield better protection under higher load operating conditions.
Which is better 10W 40 or 15W40?
