Question about oil changes

Last time I got one they slapped a sticker on that said next one due (date/mileage). Well the date is here but I'm not anywhere near the mileage. So which do I go by?

I always go by mileage. Hope I'm correct.
Valvoline wants me to come back every 3,000 miles, but they can forget that. I use synthetic oil and Toyota didn't even change it but every 10,000 miles when I bought it new and it was under a service plan. I try to get in between 8-10k.

My car has a "Oil Life" indicator - I generally go by that.

Or miles. Obviously the mileage has more of an effect than time, because I might not have driven it anywhere.

What kind of driving are you doing now? Long trips regularly? Or lots of short couple mile trips? If it's the short trips, change the oil sooner than the mileage sticker. Short drives contaminate the oil faster and it doesn't get hot enough often enough to burn off the moisture, fuel, etc....

I go by 7000 miles in my daily commuter cars to DC with Mobile 1 full synthetic (they have automated reminders). My 220k mile truck that I only use for dump runs and my classic Mustangs, I'll change them annually with Mobile 1 as well.

When I was doing a lot of highway driving, it got changed out after every long trip or 6000 miles. Now that the truck sits for extended periods and 99% of my driving is local short trips, I change it out at 3000 miles or 1 year, whichever comes first.

Rule of thumb is the mileage target or annually whichever comes first. If you are using synthetic, which you should, then anything newer than say the year 2000 should be 7k. But check your owners manual. Lots of places will try and sell you on a 3k interval when you don't need it.

Mostly in town, short couple miles. I filled up with gas on Feb 1 and still have half a tank. That type of driving. :lol:

Old data or methods ....

3 months or 3000 miles was because the additives evaporated from the oil from sitting [ does not really make sense ]

@Sneakers is probably the closest if you are not getting the engine good and hot to burn off contaminants you probably need to change sooner


This was interesting ...

My recently purchased 2024 Rav4 is expected to get it's first oil change at 10,000 miles. It is 3 or 4 months old and at best, I think I've put 2000 miles on it.

:yikes: Change it at 2-3000. Brand new engines have contaminates in them, bits of metal, etc. Do yourself a HUGE favor and get it changed WAY before the recommended mileage. Same with the 2nd change. It's a cheap preventative measure.

For your consideration ...

You should get it changed sooner with that kind of driving, at 3000-5000 miles. Short trips don't allow for the engine to fully get up to operating temps long enough to allow all the moisture to evaporate that condenses in the oil after cool down.

With Toyota, the first five maintenances are covered by Toyota. They are every 6 months or 5,000 miles which ever comes first but there is a time limit.

Should not go longer than a year between changes if you don't hit the mileage.

Old days yes. Even today’s oils are engineered better and last longer you are still at the peril of your oil filter. Oil filters will not last as long as the oil.
