Oil recommendations for Toyota Yaris

Choose your poison. If you are gonna' change at 5K, noone here will be able to recommend an oil that will make your vehicle last any longer. If you are looking for an oil to do that you could consider Motul, Redline, Amsoil or GC..and even that's a stretch.
 
Use what Toyota recommends whether it be 5W30 or 5W20 but being that you are in a hot, humid city with mostly city driving, I think you should shorten your OCI to 3000 miles.

I've never seen it stated better or more simply. Just make sure it's a known brand with an API donut on the bottle in the right grade as recommended by your owner's manual or oil fill cap. Some of the super-cheap oils (dollar store type no-name brands) are not API certified, may not be multigrade, and may not even be detergent oils.
 
what will keep your engine lasting a long time..make sure the oil is full, changed with reasonable oci, and not a coolant leaker.
 
M1 5W30 will work great so will pennzoil platnium 5W30. If you want cheaper then that Havoline or Chevron Supreme 5W30.
 
Thanks for the replies.

I just thought perhaps someone familar with UOA's seen a trend favorable to small Toyota engines.
 
Mobil claims the recommended viscosity for the 1.5L is 5W-30. I am almost sure Toyota changed the recommendation to 5W-20 for this engine if its the same as the Scion XB. Given the 5000 mi / 6 month OCI required for warranty I would go with Motorcraft Synthetic Blend, Pennzoil, Castrol GTX, Havoline "Deposit Shield", etc. No need for synthetic with 5000 mi OCI.
 
Were do think I got my recomendations from??? If you look at Toytoa's they all do great on M1 and just as well on the other oils. It does not make sense to recomend a 10qt. oil that will not outperform the oils I listed. This is especialy true if you are doing a short OCI! If you look at the Toyota UOA on this site you will see that all the oils I listed have done great. Their are some that have done better but not by much and they cost a lot more!

Chevron,Havoline ,Motorcraft ,Tropartic,CastrolGTX ,Pennzoil, Study up the uoa section there is more than one page .You do not need synthetic oil for 5,000 mile oil changes.What about the trans oil?

so which one:
Mobile 1 5W50
Shell Helix 5W40
castrol TWS 10W60
motul x-cess 5w40
???




Conventional Pennzoil was the best I've run so far in my Toyota 4 cyl.

Better than Mobil 1, Castrol Syntec, Castrol Blend, Mobil DC.

Thats what my UOAs on all the above oils showed. Very low to no wear metals over the winter for a 5k oci.

Take care, Bill
