Can You Use Multigrade Oil?

Multigrade oils are engine oils which can be used in a wide temperature range. ... This means that the lubricant film does not break off even at peak temperatures in the engine. Until the 1960s, cars were still operated with monograde oils that were suitable for either summer or winter use.

What is meant by multigrade oil?

A multigrade oil is an oil that meets the requirements of multiple grades — one “W” grade and one single grade, e.g., 5W-30 or 15W-40, etc. This grading system has the advantage over the ISO system in that it defines the viscosity performance of the oil at both the low-temperature range and the high-temperature range.

What is the difference between single grade oil and multigrade oil?

Multigrade oils flow better during a cold start, so the engine cranks faster, which is easier on the battery and starter. ... Another plus: Multigrade oil gives you a better chance of starting, especially if pre-heat is not available.
