Owner reviews for engine oil

I use Mobil-1 Advanced Fuel Economy 0W-30. It meets API SP (and SN Plus of course) and is available at Walmart pretty much everywhere for *cheap*.

AmsOil signature 0w30. It exceeds the factory spec.

The best performing oil for cold starts is probably Pennzoil platinum full synthetic if your particular prius uses 0w-20. It is made from syn gas, and is particularly thin.

For comparison, i got 6,000 miles out of Pennzoil platinum vs royal purple, with which i would get 5,000 miles prior to the oil changing color and about a 1 to 2 percent dip in fuel economy. Regardless of the wear additives, Pennzoil platinum lasts longer, again likely due to the cold start performance and the way the hybrid drivetrain works.

I personally use mobile1 with a Lucas oil stabilizer. Oil still looks pretty clean when I change it.

I use mobil1 or castrol full synth 0W-20 for prius engines below 200k and 0W-30 for those above it. More than 30k mi now so far so good. I like the castrol better bec my engines sounds much quieter vs m1.

I use Mobil1 full synthetic 0w-20 advance fuel economy oil. As long as you get oil that meets the manufactures's spec, you will be fine.

From the 21 Camry owners manual: “SAE 0W-16 is the best choice for good fuel economy and good starting in cold weather. If SAE 0W-16 is not available, 0W-20 oil may be used. However, it must be replaced with 0W-16 at the next oil change.”

Amsoil ????

I use castrol magnatec beucase it has some kindof ionization tech where it sticks to metal surfaces to reduce start up wear which the prius is constanly starting/stopping.

I've been using Motul for hybrid cars.
