Frequently Asked Questions
What type of engine oil do I need?
The oil viscosity is usually printed on the oil cap. If it is not, then you need to find the owner's manual under the recommended fluids and lubricants section typically at the end of the owner's manual.
- at the oil cap
- owner's manual
- sticker by the top radiator support
Should I change the oil when the engine is hot or cold?
- There is a lot of discussion on this topic of whether you should change the oil when the engine is hot or cold. Ideally, the oil should be slightly warm so it can flow easily but not burn you.
How much does it cost to change the oil?
- Anywhere from $19.99 to $150. A four-cylinder engine that takes 5w30 or 0w20, such as a Honda Civic or Ford Focus, will only cost you about $20. A Mercedes-Benz E-Class that takes 8.5L synthetic oil and fleece oil filter may cost as much as $150 at the dealer. Two of the main factors that play a role in engine oil cost are the oil type (synthetic, synthetic blend, conventional) and oil quantity required. Oil filter quality and how easy it is to remove may also play a role in the price of an oil change.
How often should I change engine oil?
Typical recommended intervals for most vehicles.
- Conventional Oil - Every 3,000 miles
- Synthetic Blend - Every 5,000 miles
- Synthetic Oil - Every 7500-10,000 miles (verify owner's manual)
Follow the recommended manufacturer intervals.
Can I change the engine oil at home?
- Yes, you can. Follow this guide. We hope that once you go over all the steps, you will feel confident about the procedure to change the engine oil at home.
Can I change engine oil once a year?
- While the age of oil can play a factor in the engine oil life, you need to pay closer attention to the miles driven. If you drive very little (under 5,000 miles) and use synthetic oil, you should be ok with changing the oil once a year.
Can I change engine oil but not filter?
- Not recommended. You should change the oil filter at the same time that you change the engine oil. Oil filters do not last forever, and if not changed regularly, they will not filter the oil or, even worse, clog. In which case, the oil may bypass the oil filter altogether, which is a situation you don't want as you may shorten the life of the engine.
Is it necessary to change engine oil every year?
- Yes. Most drivers should change the engine oil at least twice if not more per year, depending on the oil type and miles driven. If you put about 15,000 miles per year which is the national average in the US, you should change the engine oil at least twice per year. Assuming that you are using synthetic oil and a good oil filter.
Should I change the engine oil before or after storing the car for long periods?
- Change the engine oil if stored for over 6 months. Oil can lose its lubricating properties when sitting for an extended period of time. Change the engine oil if your car has been sitting for a long time.
What happens if I don't change the oil?
- You are shortening the life of your car. Sludge may build up. The engine may start to knock. Most importantly, bearings will wear much faster. You may not notice any symptoms right away, but you are causing premature wear to your car engine.
How much oil do I need to add?
- Check on your owner's manual. Every car has a different capacity. There is no correlation between the number of cylinders and oil capacity. Some 6 cylinder engines require only four quarts, while others may require eight quarts. Always check the owner's manual. You don't want to overfill or underfill.
