Is 10W-40 better than 0W 40?

Is 10W-40 better than 0W 40?

The thinner the oil is for starting a cold engine the better – and that is regardless of ambient temperatures. A 0W-40 oil is a much better alternative than a 10W-40 oil. The second number is the tested viscosity rating at operating temps (ignoring the precise testing parameters).

Is it OK to use 15W40 instead of 10w30?

Don’t sacrifice wear protection for fuel economy. Since 10W-30 is thinner than 15W-40, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for 10W-30 to protect as well and last as long as 15W-40.

Can I use 10W40 in my diesel?

Premium Protection 10W-40 Synthetic Motor Oil. For use in both gasoline and diesel engines. Ideal for applications where the extra protection of a higher-viscosity oil is desired.

What is 0w 40 oil used for?

The 0W40 engine oils from ADDINOL are high-quality multigrade oils, based on oils of the latest synthesis technology combined with powerful and innovative additives. The oils have excellent performance and cold start behaviour. They are used in powerful petrol and diesel engines in passenger cars and vans.

Will 10W40 hurt a 15W40 engine?

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.

Is 10W40 oil for petrol or diesel?

10w40 semi synthetic oil for petrol and diesel engines.

Is 15W40 thicker than SAE 30?

It is the same thickness as the 10W-30 at operating temperatures. The difference is when you turn your engine off for the night. Both oils thicken over the evening and night. They both had a thickness, a viscosity of 10 when you got home and turned your engine off.
