Can I use 10W 40 instead of 15w50?
At low temperature the 10W oil will flow better than a 15W oil. So the 15W-50 oil is “thicker” at cold temperatures than the 10W-40, therefore it will flow worse on start up; but being a little “thicker” it and maintains its viscosity at high temperatures better than the 10W-40.
Can I use 20w 50 instead of 15w50?
Yes,it would not make much difference. Important thing is to get the last digit,ie 50 correct. First digits are an indication of normal temperature viscosity or in layman terms how easy it would be to start the engine. But like I said it would be fine to interchange 20w50 with 15w50.
Is 15w50 good?
What is the difference between 15w40 and 15w50? 15w-50 as an engine oil lubricant is slightly more viscous in viscosity as opposed to 15w-40. As mentioned above, the oil is fit to provide good engine lubrication as well as great protection. Furthermore, the oil is also known to have a good drain interval.
Which oil is thicker 10W40 or 15w50?
Motor oil grade represents the weight of the oil when cold, as well as at operating temperatures. A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures. The winter viscosity number dictates cold-start performance.
What does 15w50 oil mean?
“15W” refers to the flowability at cold temperatures (W=winter). The oil is still pumpable down to -25 °C, i.e. liquid enough to distribute in the engine. The number “50” describes the flowability of the engine oil at an operating temperature of 100 °C.
Who makes Vanguard 15W50 oil?

What is 15W50 oil?
What does 15W50 mean? 15W50 refers to the SAE class according to which the engine oil was classified. The SAE class describes the viscosity of an oil, i.e. its flow properties depending on the operating temperature. Engine oils of class 15W50 belong to the multi-grade oils.
