Engine Armour 15W-40 is suitable for most petrol powered cars and some light duty diesel passenger vehicles including turbocharged and multi-valve engines. It provides protection to engine components for everyday driving conditions.

Does Valvoline work on diesel engines?

Valvoline Premium Blue is exclusively recommended and endorsed by Cummins and specially designed to provide advanced lubricant performance in diesel and gas engines of all ages, including the latest low emission engines.

When should I use 15W-40 oil?

The 40 indicates fluidity at high temperatures, so the more viscosity it maintains at high temperatures, as oil usually thins when exposed to heat. The 15W-40 oil is better suited for temperate or hot climates where ambient temperature, as well as vehicle’s operating temperature, can be very high.

What does 15W mean?

A single grade oil like 15W or SAE 40 oil has a high viscosity when cold and a lower viscosity when hot. The first number 15W is the viscosity of the oil at cold temperature, and the second number 40 is the viscosity at 100 °C. The 15W40 designation means that the oil is a multigrade oil.

Is it bad to use 15w40?

Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine’s crank. No it won’t blow off,you will just wear your engine out quicker because the oil won’t flow to the moving parts as quickly !

What is the difference between 15w40 and 11w40 oil?

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. A lower number indicates that the cold oil will be thinner, hence applying less static friction on the engine, and less drag.

What is the different between 15w40 and 15w50?

thus for your question, 15W40 and 15W50 are equally viscous, but the ..50 will have more thickening polymers in it than the ..40. the 15W40 is more viscous than the 10W40. 0

What is meant by 15w40 for generator?

For a gas generator, most people use plain SAE 30 because they don’t ever run in cold weather (below freezing) and SAE 30 is optimum for warmer weather (per the Onan Handbook). 10W30 or 15W40 is optimum if you want to cover sub-freezing temperature operation as well.
