Can I use 5w40 instead of SAE 30?

Can I use 5w40 instead of SAE 30?

You need to keep the second number the same as your straight SAE 30, this is the viscosity of the oil at operating temperature. Yes; you can make use of it.

What is 15W 30 oil used for?

The new Delo 400 SD SAE 15W-30 is a CJ-4 engine oil blend specifically formulated for what Jim Gambill, Delo brand manager for Chevron, called “severe duty” cycles characterized in trucking by higher engine revving due to stop-and-go driving on congested roadways as well as engine idling restrictions.

Can I use 5W30 instead of 15W40?

If the manufacturer’s recommendation for your engine allows you to use 5W30 oil, you can use either 5W30 or 15W40. If your engine only calls for 15W40, please only use that grade of oil; big engines are too expensive to risk.

Can I use 10W-30 instead of 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 oil is thicker 10W40 or 15W40?

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. 10W40 oil will perform cold starts better than 15W40 oil.

Is it OK to put 10W40 in a 10W30?

Mixing 10W30 with 10W40 Some say that mixing them is fine as long as you don’t live in freezing weather. Even if you put together synthetic and conventional blends of these motor oils, they show no harm to your vehicle.

Which is better 10W30 or 10W40?

The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature. Using the correct viscosity oil eases starting, reduces friction, and slows wear.

What happens if I put 10w40 instead of 5w30?

If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.

Can I use 10W 30 instead of 5W30?

Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.

What happens if you use 5w20 instead of 5w30?

If you put in 5W-30 oil instead of 5W-20 when the latter is the grade suggested by your vehicle’s manufacturer, damage to internal engine parts can occur. Additionally, your engine may experience performance issues such as diminished fuel economy and horsepower.

Can I use SAE 30 instead of 5w30 in my car?

5w-30 is fine to use. It has the same flow rate as SAE30 at normal operating temps. The way oil works is, the first number is flow rate at ambient temp.
