2018 Toyota Corolla Oil Change Interval?

[We're Metals]

A few things to consider. The OP is in California, but where is the car located? Most likely in CA, but we don't know.

California is a big state. There are areas where the climate is not so mild such as in the Sierras and several northern counties.

Does not Toyota have 1 viscosity recommendation for all climates?

If she drives under 7500 miles a year change it once a year. I would try Kirkland brand 5w30 now on sale at my Costco for $30.99 for two 5 Quart Jugs.

Sounds like Mom is driving around 3k per year and lives in a stable, mild climate. Her worst enemy, if the vehicle is not garage-kept, would be the nearby ocean and it's salt content.

I would change it every two years (or 6k), whichever comes first.

Yearly OCI's would be the safe bet but I would have zero problems going two years for that particular situation you described.

That is against Toyotas service service schedule

Every 6 months and call it a day

With the short trips, and infrequent use I’d change it every 5,000 miles. And I personally wouldn’t let it go past a year if she can’t get it to 5,000 miles in that time. I just don’t like oil sitting in a sump for that long when it’s not being driven...with moisture, etc.

Now if she was driving 500 highway miles a week??? I’d probably say 10,000 mile intervals on that thing. Someone just posted a photo of a 2018 Corolla with 500,000 plus miles on it (average of over 200 miles a day for five years)...and posted the service history...10,000 mile intervals religiously. Not one single engine repair or issue. The transmission was replaced at 330,000 miles however (CVT).
