What is 15W-30 oil used for?
Delo® 400 SD SAE 15W-30 is a premium and innovative diesel engine oil intended for engines that have duty cycles which qualify as “severe duty.” These include reducing idling time by turning the engine off at stops or deliveries, stop and go in heavy traffic or city delivery, or situations where engine cooling may be …
Is 15w40 a synthetic oil?
Mobil Delvac™ Extreme 15W-40 is a synthetic, high-performance diesel engine oil that helps extend engine life while providing long drain capability for modern diesel engines operating in extreme conditions.
Which oil is better 10w30 or 15w40?
Because 10W-30 is thinner than 15W-40 oil, its film strength can be weaker and it can be more prone to oxidation. High quality 10W-30 oils can perform as well, and better than industry-standard 15W-40 oils.
What is the difference between 15W-40 and 10W 30?
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.
Is 15W40 only for diesel?
However, it remains more popular with diesel vehicles as 15W-40 viscosity is commonly used with diesel cars and trucks. Not only diesel engines but it can also be used in other heavy-duty gasoline or natural gas engines, like in equipment.
Is Synthetic Oil Better?
Is synthetic oil better for my engine than conventional oil? Yes, synthetic oil is better for your engine than conventional oil. Although conventional oil (i.e., mineral oil) can provide adequate lubrication performance, it can’t compete with the overall engine performance and protection provided by synthetics.
What is the difference between 15w40 and 15W50?
15w-50 has a viscosity grade of 40. It is thicker and heavier as compared to 15w-40. It has been recommended for engines that have high performance. Most essentially used in motorsports, they are equipped to operate under heated and stressful conditions.
What happens if I 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 15W40 instead of 30w?
15W40 will work fine in most diesels. The only manufactuer that I have seen put out otherwise is Detriot with their 2 strokes. We run 15w40 for ease of logistics. There are probably better oils for each engine in different operating conditions but 15w40 is well suited for pretty much any diesel in normal conditions.
