We picked up our 2008 Toyota Prius September 27. We've driven almost 3,500 miles so far, so I'm starting to think about our first oil change.

So...what sort of mileage interval do folks stick to for their oil changes? What sort of oil do you use? Do you change it at home, at the dealer, or an oil-change "service?"

Any thoughts would be greatly appreciated. Thanks!

 

There is no need to change before the recommended 5000 mi/8000 km, according to those who have had analysis done. If you extend the interval, it could void parts of your warranty. I changed Pearl's oil a few months ago at 8000 km, putting in Mobil 1 5W30. Will do so again after a further 8000 km. Oil and filter each time. Takes about 10 min.

 

Hi,

I do two changes per year:

1. Fall - to get rid of the accumulated summer pollen, dirt and grit and put in a winter grade oil.
2. Spring - to get rid of the accumulated condensation and put in a summer grade oil.

Since I'm running about 19,000 miles per year, that comes in about 9,500 miles per change. My last change, I tested the oil after just 7,500 miles and it had very little loss in viscosity and the other numbers were pretty good too.

Toyota knows their engines, changing the oil sooner is a waste of good oil. Just follow the owners manual.

 

6 months/8,000kms. Usually the 8,000kms comes first around the 5th month.
