2010 Toyota Corolla 1.8L, Phillips 66 Shield Choice 10w30 syn blend, 5,022 OCI

[Pat in Speedway]

Just giving different weights and brands a try to see how they compare. First run was Amsoil XL 0w20. The P66 10w30 sheared down to the 20's, which is recommended for this engine anyway, so not concerned about it. But hey, it was $1.99/qt at Orscheln's, so at that price, it appears to be a good value oil. I ran it until my wife told me the change light came on, which is at 5k. I've got Amsoil OE 5w30 in it now, so I'll run another UOA to see how it does. Ran a Toyota oil filter with it.

That engine is easy on oil. Sounds like you found a winner with the P66 10W30. I would not mess with the fancy stuff unless you are looking to run 10-15K OCIs.

Good metal wear rates.
I would incline to do 10k or more with Philips in this engine.

I stock up with various weights of Choice when it's on sale at Orscheln's as well.

Basically the only oil used since Day One in these vehicles:
2006 Corolla = 247,000 miles
1999 Dodge Ram 300,000+ miles
2001 Dodge Ram 287,000 miles
2001 Grand Cherokee 238,000 miles

Except for a hard winter.. I think the P66 is wearing better for you.

I tend to agree. However, the Amsoil was run during winter in Indiana, and we had some pretty harsh temps below -10 on a few occasions. Not worried about changing up viscosities either. I've got a copy of the oil recommendation page from an Aussie Corolla with the same engine, and it indicates you can run up to 20w50 in this engine if you want. Probably won't experiment that high though!

 

[Revving2Redline]

No I don't blame you.

10W30 will be fine even in Indiana winters. I know we used group I 10W30 for our cars in Anderson year round. But I understand if you want to use a oil with a lower winter rating.

Hello , you see in the attached PDF that this engine and other ZR series engines can ran the oil viscosity range from 0w20 to 20w50 with absolutely no structural limitations, read page 6 , just you need to be careful with start up temperature... those engines are incredibly tough.
