Choosing the Right Engine Oil
The Honda Accord is one of the most reliable vehicles ever built! So it is great you are taking care of it by changing the oil regularly (I recommend every 5000 miles).
The best type of oil to put in your engine depends on a number of factors. That is why I am writing this article, so you don’t have to!
At the end of the day, there are mainly 2 things you need to think about when choosing the best oil for your vehicle: mileage and climate. Even though there are a host of other things to consider, such as how you drive, what your daily drive is like, or whether your vehicle has any known problems. I’m going to assume you are a ‘typical’ driver, you live in a climate with cold winters and fairly warm summers, and the car doesn’t have major issues.
Concerning mileage, an important factor is also the age of the vehicle in terms of how many miles are on the car. “High Mileage” is considered 75,000 miles or more, which to a Honda owner, actually isn’t that much! It is pretty common to see Honda Accords with well over 250,000 miles, still going strong! The reason that high mileage motor oil can be important is because of the specific formulation of additives. The additives for high-mileage vehicles are designed to restore the shape and pliability of engine seals bringing new life to those that may have hardened over time. High-mileage oils also tend to be toward the higher range of viscosities within each specification to account for increased tolerances that may exist in vehicles that are older and have experienced more wear.
How to Change Oil in a Honda Accord?
Changing the oil in an Accord is very straightforward and takes about 20-30 minutes; most of the time is spent waiting for the used oil to drain out of the car! Please visit this post for details on changing the oil in an Accord. All you’ll need is a 17mm socket, funnel, 4.4 qts of oil, a drain pan, and an oil filter.
What Viscosity is Right for Me?
When you see the numbers on the bottle like “5W-20”, very simply, the first number corresponds to the viscosity when the oil is cold (think “W” for “winter”). The number before the “W” refers to the viscosity rating at 0°C. A lower number means there is less thickening of the oil at lower temperatures. The number after the dash (-) refers to the viscosity of the oil measured at 100°C, and is an indication of the oil’s rate of thinning at higher temperatures. Visit this post for a more detailed explanation of the SAE numbers.
Why should I use Synthetic Oil?
- Synthetic oil allows your vehicle to get better gas mileage. Since synthetic oil can be manufactured down to higher viscosity ratings than conventional oils, the oil flows more freely, allowing the engine to not have to work as hard.
- Synthetic oils can also go longer between oil changes. This not only saves YOU money, but also reduces waste.
- Synthetic oils increase engine longevity. If everything else is the same, an engine will last longer if synthetic oil is used.
What Oil is the Best Oil?
Before 2011, Honda recommended the use of 5W-20 oil in their Accords. From 2011 and onward, the recommendation changed from 5W-20 to 0W-20. The reasons for this comes down to tighter tolerances in engine manufacturing processes and fuel economy. In fact, if a vehicle will be used for towing, 5W-30 oil is recommended in order to increase the engine life.
For these reasons, the following oil types are recommended based on the year of the vehicle.
For a Honda Accord made in 2011 or newer, use this:
Mobil 1 Extended Performance Full-Synthetic 0W-20
