Choosing the Right Engine Oil

The Toyota Corolla 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, and as a result, people will be arguing about this until the end of time. In my quest to answer this question for myself, I ended up going down the rabbit hole… When I finally came out the other end, after reading what seemed like hundreds of blog posts, articles, and even technical research papers, I decided that I don’t want anyone else to have to go through that. 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.

How to Change Oil in a Toyota Corolla?

Changing the oil in a Corolla 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 a Corolla. All you’ll need is a 14mm socket, funnel, 3.9 US qts of oil (for a 2004, check your owner’s manual for exact quantity), a drain pan, and an oil filter.

What Viscosity is Right for Me?

When you see the numbers on the bottle like “5W-30”, 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?

There used to be quite a debate on whether conventional or synthetic oil was ‘better.’ All kinds of myths were floating around because people are resistant to change (sometimes for very good reason). There were worries about synthetic oil degrading seals faster, not clinging to surfaces as well, or susceptible to sludge. These were largely unfounded, and the consensus has overwhelmingly swung towards synthetics.

The main reason that conventional oils are still used is the lower cost, but from a performance standpoint, synthetics win. Some of the benefits of synthetic oil include:

  1. 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.
  2. Synthetic oils can also go longer between oil changes. This not only saves YOU money, but also reduces waste.
  3. 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 2009, Toyota recommended the use of 5W-30 oil in their Corollas. From 2009 and onward, the recommendation changed from 5W-30 to 0W-20. The reasons for this come down to tighter tolerances in engine manufacturing processes and fuel economy. In fact, in some cases, Toyotas sold in other countries (such as Australia) specify the use of 5W-30 engine oil, since the mandated fuel economy requirements have not yet been tightened there. Also, often 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 Toyota Corolla made in 2009 or after, use this:

Mobil 1 Extended Performance Full-Synthetic 0W-20

For a Toyota Corolla Made before 2009, use this:

How Much Oil goes in a Toyota Corolla?

My 2004 Toyota Corolla takes 3.9 US Quarts when the oil is changed with a filter. Check your manual for the correct amount for your vehicle (For example, a 2019 takes 4.4 US qts – Thanks Terry!).

  1. The Toyota dealership in south Florida is now using 5w-30 for conventional oil changes for my 2010 Corolla LE. Is this ok?

  2. I have never used synthetic engine oil in my Toyota Corolla 2006 1.8 . My mechanic recommended 10/30 car has only done 125.000 k bought car two years ago , I am qualified mechanic but 83 year old .cost factor is high in consideration of oil, I change my oil and filter every 5.000 k do you think 10/30 ok or save up for synthetic not wealthy ,

    1. Hi! Changing your oil regularly, and at the recommended interval is by far the most important factor, which it sounds like you are doing, so I believe you are fine continuing with conventional oil!
      All the best to you,

  3. All Toyota Corollas do NOT take 3.9 US qts , I have a 2019 and it is 4.4 US qts with filter change or 4.1 without

  4. December 8 2021- Thank you! Clear, comprehensive and great help. Great value.

  5. great great help for your article , have 03 180 k living on a small SS is no way i can get another car, needed to go back/ forth doctors as i’m fighting my second cancer so i have to make it last forever. you know what i meant
