What kind of oil does a Honda Accord use?
The same kind of fuel is required by both of the Accord’s various engine configurations for this model year. That oil is completely synthetic SAE 0w-20. Consult the owner’s manual for the 2019 Honda Accord for more detailed information. You should check there to find all the information you require about your car.
Open the hood of your car if you still need some assurance. The oil type is frequently printed directly on the motor oil cap next to your engine. That may provide you some extra information.
The amount of oil required by a 2008 Honda Accord
The 2008 Honda Accord’s engine oil volume is 4.2 quarts. You should add a total of 4.2 quarts of new oil now that the old oil has been completely drained out during an oil change.
It’s natural for the oil level to slowly drop as you drive your car. Just make sure to check your oil frequently—every two gas fill-ups or once a month is a good schedule—to make sure it is within the recommended range. You will know it’s time to top it off if it drops below the range shown on your oil dipstick.
What kind of oil does a 2008 Honda Accord need?
It’s crucial to use the engine oil that Honda recommends for your vehicle. Because different engine oils have varying viscosity weights, they maintain a variable liquid thickness at different temperatures. For the 2008 Accord, the recommended type of oil to use in your car’s engine is 0W-20.
Utilizing Genuine Honda Motor Oil of the highest grade and weighted at 0W-20 is highly advised by Honda. You can attempt a few alternatives if you can’t find the Honda brand easily and urgently need oil. Look for Valvoline Advanced Full Synthetic 0W-20 Motor Oil or Mobil 1 Extended Performance Synthetic Motor Oil.
Here is what your oil type’s numbers and letters indicate if you’re curious about how engine oils are rated:
Your oil type’s designation of 0W denotes the viscosity, or thickness, of the oil in cold conditions. Winter is indicated by the W and the number 0 rates the viscosity level.
The viscosity level of your oil when your car’s engine is running normally, which is at a temperature of about 212F, is indicated by the 20 at the end of the oil type. A viscosity rating of 20 indicates that even at high temperatures, the oil is still fairly viscous.
Honda advises using synthetic motor oil?
Can I run my Honda engine on synthetic oil? Motor oils made of petroleum are used to lubricate Honda engines throughout development, testing, and certification. Synthetic oils are permitted, but any motor oil used in our engines must adhere to the owner’s manual’s oil specifications.
Definition of 5w20 Vs. 5w30
The engine oil type 5w20 is distinguished by its oil weight of 20 in warm weather and a winter grade of 5. It has a lower viscosity than 5w30. While 5w30 has the same viscosity rating of 5 in the winter, it has an oil weight of 30 in the summer, making it thicker.
Working conditions for 5w20 Vs. 5w30
For use in cooler climates, use 5w20. As it moves swiftly and smoothly to deeper engine components with less friction, it makes it possible for a vehicle’s engine to start up rapidly. It immediately lubricates the components. In contrast, 5w30 performs well in warm environments. Unlike 5w20, it does not thin out quickly when exposed to heat. The engine components are therefore better protected overall when using 5w30 at operational temperatures.
Performance of 5w20 Vs. 5w30
These two engine oils function well in the environments for which they were created. Due to its low viscosity and reduced friction in the engine parts, 5w20 is a champion in colder regions with speedier engine starts. In hotter regions where a thick oil is required to resist the higher temperatures, 5w30 excels. Naturally, the engine will heat up more, necessitating a thicker oil. In colder climates, 5w20 is associated with higher performance and fuel economy, whereas 5w30 is associated with better overall engine component protection.
What occurs if I substitute a synthetic blend for a full synthetic?
Since I’ve been working as a technician for eight years, I’ve always been told that switching from synthetic to traditional oil is not possible. I have witnessed the harm that returning to conventional causes. Is it accurate to say that switching back to conventional won’t harm your engine?
Answer
Although moving back and forth between fully synthetic and conventional oil won’t harm the engine, synthetic oils normally offer more protection than conventional lubricants. Naturally, this is based on the state of the engine at the time and the caliber of the regular oil being used.
When should I use oil that is fully synthetic?
The drawback is that synthetic motor oil can be two to four times more expensive than normal oil. So you don’t need it unless your owner’s handbook specifically says synthetic.
- if your engine is elderly and prone to sludge buildup When oil degrades, a gunky residue is left behind that might obstruct oil tubes and cause an abrupt engine shutdown. Several engines from brands including Chrysler, Toyota, and Volkswagen, among others, were particularly prone to sludge buildup in the early 2000s. This problematic sludge is less likely to form while using synthetic oil.
- Standard motor oil might never get warm enough to burn off moisture and contaminants that can build up if you frequently make short excursions. That might speed up the decomposition of conventional oil.
- Synthetic oil helps protect the engine from strain and won’t wear out as rapidly as traditional oil if you live in an area with extremely cold winters or extremely hot summers, or if you tow or haul large objects with your car.
Even though synthetics normally last for more miles, routine oil changes are still vital, and you shouldn’t wait longer than the manufacturer recommends—typically every six months or a year.
When synthetic is used, your oil will last longer and need fewer changes. That has significant environmental advantages as well because spent motor oil is a significant source of harmful waste in water.

Is complete synthetic oil more durable?
Better at Higher Temperatures: Because synthetic oil doesn’t thicken as much in high temperatures, it lasts longer than regular oil.
Your Owner’s Manual
Although it’s really easy, owners manuals are frequently disregarded. To find out the appropriate viscosity of the motor oil you should use, always consult your owner’s handbook. Use the 0W20 and 5W20 variations interchangeably, depending on the weather, if they are both on the list.
Location
Given that both 0W20 and 5W20 motor oils operate in much the same temperature range, it is critical to think about where you will be using the car. The operating temperature range for synthetic oil is -40C to 20C for 0W-20 and -35C to 20C for 5W20 (5W20 synthetic oil). Being aware of these facts means two things:
- In places like Florida when the temperature is above 20C/68F, you cannot use either 0W20 or 5W20.
- If you reside in a region with extremely low temperatures, such as Alaska or Maine, it is preferable to use 0W20 oil.
Viscosity
The motor oil will flow more smoothly the lower the number is. At beginning temperatures, a 0W20 will be more fluid than a 5W20, but both will function similarly at normal engine operating temperatures. Keep in mind that engine oils naturally become thinner during heating and thicken while cooling.
Quality Testing
Any oil brand with the appropriate viscosity grade and the API donut symbol is acceptable. The oil has passed the testing required for SL service, as indicated by the starburst sign.
The API donut indicates that your motor oil passed the current SL service rating test after being tested by the American Petroleum Institute. ACEA (Association des Constructeurs Europeens d’Automobiles) is the counterpart of API in Europe.
Manufacturer Requirements
If your vehicle is substantially loaded, the machine designer would typically advise using an oil that has a high viscosity and is heavy like honey. However, if it moves quickly, a lubricant that can move out of the way and then move back in is preferable.
Fuel Economy
Despite the fact that both 5W20 and 0W20 (0W20 synthetic oil) can be used at 20C/68F, 0W20 is thinner than 5W20 at cold engine temperatures, particularly in the initial minutes after starting your automobile. Because it gives the car slightly higher fuel economy than the 5W20, new models specify it. The 0W20 model satisfies a turbo-diesel engine’s requirements as well.
Is Honda engine oil required?
Do you have to use fluids from the Honda brand? Yes is the clear-cut response. Corrosion is the key, and Honda fluids are the best fluid to reduce corrosion and keep your Honda dependable.
Can you combine ordinary and synthetic oil?
Whenever you have a crucial question regarding motor oil!
You’ve arrived at the proper location. Because Jiffy Lube is an oil expert. Every day, hundreds of drivers are assisted by qualified Jiffy Lube experts in choosing the proper motor oil, including whether to use synthetic or conventional oil and whether it is OK to combine different types of motor oil.
So, is it possible to combine synthetic and conventional oil? Yes. Mixing shouldn’t harm your engine if it’s something you do infrequently. To keep you moving until your next regularly planned maintenance check, let’s assume you wish to top off your oil. If the oil you use has the weight (or viscosity) indicated in your owner’s manual, mixing is acceptable.
What occurs if I use 5W-20 rather than 5W 30?
Most mechanics will caution you against combining two multigrade lubricants, even though some engines may permit it. Using the incorrect oil or combining two different oils might occasionally void your car’s warranty and result in exorbitant repair costs.
Additionally, you run the danger of shortening the life of your internal combustion engine.
Mixing 5W-20 and 5W-30 (or any other oils, for that matter) could cause your engine to wear down more quickly and eventually have issues with the important engine parts’ fundamental operation.
Additionally, combining various viscosity grade oils won’t have any apparent effects, even if your engine permits it. Therefore, even if the oil viscosity grade your car engine needs can vary, it’s preferable to just use one viscosity rating at a time.
