Best oil to use for 2001 corolla..?

[Killjoy22]

Any thoughts? What oil do you use and why?

Any oil as long as you follow a maintenance schedule. I live in a colder climate so Winter Synthetic 0W20 summer 5W30. But our temperature goes from -40c to 35c. I had a noise valve at 180,000 KM topped it up with STP Ultimate Synthetic oil additive and the noisy valve went away. Remember to flush the engine occasionally to get rid of sludge and varnish.

5W-30 full synthetic year round, even if you get snow...

Since these engines can develop early signs of oil burning, its safe to assume that 5W30 synthetic is the way to go. If the engine is already consuming oil, synthetic oil would do no good except drain your wallet.
