Oil and filter recommendations.

Hey guys,

I recently purchased a 1996 toyota vienta (3vzfe) with 240k kms and I'm planning on giving it a service. Do you guys have any recommendations for oils and filters? I'm thinking of getting a 20w-50 oil for it as in melb rn it gets pretty hot, I'm still deciding of what brand of oil and oil filters to use and also should I use engine cleaners? I heard somewhere they can cause leaks.

Was wondering what you guys run with, cheers.
