Engine oil type and frequency of oil changes
What type of engine oil is best for winter and
summer and how many miles (or kms) should it be
changed. The owners manual recommends 0W20
but states that 5W20 can be used if 0W20 is not
available which makes me think 5W20 is
acceptable year round. Toyota says it should be
checked every 8000km but can be changed at
16,000 km for 0W20. Thanks.
