What happens if I use 5W-30 instead of 10w30?

What happens if I use 5W-30 instead of 10w30?

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.

Can I use 5w30 instead of 10w30 in my lawn mower?

Running Cold If your mower manual calls for a 5W-30 engine oil, using a 10W-30 oil is also acceptable. The only difference between the two oils is the low temperature point, with the 5W-30 functioning slightly better than the 10W-30.

When should I switch from 5w30 to 10w30?

The oils only differ in cold weather viscosity. If you never see temperatures below zero F then either 5W30 or 10W30 is fine. If winter temperatures are regularly below 0 degrees F then 5W30 is what you should run and you can run it year round if the 30 weight is good according to your owner’s manual.

Is 5W 30 oil OK for lawn mower?

SAE 30- Warmer temperatures, most common oil for small engines. SAE 10W-30- Varying temperature range, this grade of oil improves cold-weather starting, but may increase oil consumption. Synthetic SAE 5W-30- Best protection at all temperatures as well as improved starting with less oil consumption.

Is 5w30 oil good for lawn mower?

In cold weather conditions, you should use SAE 10W-30 or SAE 5W30 oil in your lawn mower. SAE 30 is usually the best option for smaller mowers and warm weather conditions. However, commercial mowers perform best on 15W30. Depending on the model, synthetic oil may also be suitable.

Is 5W or 10W better for winter?

The lower the W number, the better the oil will perform in colder temperatures. Typically, a 5W oil is recommended for winter use, but synthetic oils can be formulated to flow even more easily when cold.

What is the difference between 5W and 10W oil?

A 10W or 5W is the index for how easily the oil flows in winter (hence the W). A 10W oil thickens more than a 5W. The other number indicates the oil’s resistance to thinning at high temperatures.

Which oil is thicker 5W or 10W?

What motor oil is best for cold weather?

A multi-viscosity 5W30 oil flows quicker in cold weather and is recommended for year-round protection, and a synthetic 5W30 multi-viscosity will provide the best protection you can get in both extremely cold weather and extremely hot engine temperatures.
