Can I Switch From 5w30 To 10w30?

Is it OK to switch from 5w20 to 5w30?

Due to the increased resistance of the thicker 5W-30 oil, your engine will produce slightly lower fuel economy and horsepower output.

You also risk engine damage when using 5W-30 instead of 5W-20, as the internal engine components are specifically designed to be used with 5W-20 motor oil..

Which oil is thicker 5w30 or 10w40?

A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

How cold is too cold for 10w30?

Merkava_4. P.S. According to the SAE chart, -22 F is about the lowest you can go with a 10W oil before outright pumping failure occurs.

Should I use different oil in the winter?

Since lower-viscosity oils flow more readily, they provide better cold-weather startup protection compared to higher-viscosity oils. Thus it’s beneficial to switch to a lighter viscosity motor oil in winter if you can.

Is it OK to switch from 10w30 to 5w30?

You can use them interchangeably and would not likely even notice a difference at all unless it got really cold, then you’d find the 5w30 most likely cranking easier at cold start. You can absolutely run the 5w30 year around, no worries at all.

Which oil is best for high mileage engines?

Valvoline High Mileage with MaxLife Technology. … Castrol Edge High Mileage. … Mobil 1 High Mileage. … AmazonBasics High Mileage Motor Oil. … Pennzoil High Mileage Motor Oil. … Lucas Oil High Mileage Oil Stabilizer. … Royal Purple HMX High Mileage Synthetic Motor Oil.

Can I mix synthetic and regular oil?

Yes. There is no danger mixing synthetic and conventional motor oil. However, conventional oil will detract from the superior performance of synthetic oil and reduce its benefits.

Can you put 10w30 in a 5w20 engine?

Originally Answered: Can I put 10w30 instead of 5w20? You can, but you will get worse mileage, and in most cases shorten the life of your engine, as it will take longer to pump up pressure for your bearings and lifters, and won’t spray your lower cylinders for an extra second or so on each cold start.

Which oil is better 5w30 or 10w30?

5w30 is a great multigrade oil for use in low starting temperatures as well as high summer temperatures. It is also more fuel efficient since it creates less drag on the bearings and moving engine parts. 10w30 is thicker and may provide better sealing capability for older engines.

Is there a big difference between 5w30 and 10w30?

5w30 is used for light-duty engines while 10w30 is used for engines which carry heavier loads. 10w30 provides sealing action in the engine due to the fact that it is thicker than 5w30 engine oil. Thinner at lower temperatures. Thicker at lower temperatures.

Are oil additives bad for your engine?

Generally speaking, the longer oil is used, the more additives will be lost. … It may result in poor fuel economy, rust and corrosion, oil sludge, overheating, breakdowns and other serious engine damage. Aftermarket oil additives can improve oil performance between oil changes and protect your engine in the long run.

Is 5w30 or 10w30 better for winter?

At operating temperatures, both oils will have the same viscosity (30) and will flow and protect identically. If the oil will be in the engine during winter and you live in a place where it gets cold during these months, use 5w30 oil. If it will only be in the engine during the summer, use 10w30.

Is Thicker oil better for high mileage cars?

A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil — 10W — can help protect worn engine bearings as well.

What is the best oil to use in the winter?

The Bottom Line 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.

Should I use thicker oil in winter?

Thin oils that are less prone to thickening in low temperatures will help you start your engine more quickly in winter while thick oils that are less prone to thinning in hot temperatures will help your engine perform better in summer.
