0W-16 for better economy

So running through the Walmart oil section I found me some 0W 16 oil for the same price as regular. After doing some research I did not find any information if any one has ever ran it on a gen 2 Prius. I am aware the Prius takes in 5W 30.
What I did find is that that 0w 16 is supposed to give you better gas mileage, so I went ahead and took the risk... why not Prius has 240000 miles if engine goes out more of a reason to upgrade. But so far it’s been a week and nothing bad has happened, gas mileage did appear to go up in the city, has not had a chance to get on the highway so we’ll see.

 

I have seen a 2 MPG increase city driving. Weather wise, it’s still cold down we’re I live to see if it’s going to impact the car in a negative way. By then I should be running 5W 30 again since I drive the car 120 miles a day just to go to work and back and will have to be doing another oil change in a month.

Me too lol , figured that if the engine would give up I can surely convince my wife to let me get a prime ^^.

I have encountered to scenarios when it comes to oil burning on my car. To go to work I have to drive up the Oregon mountain pass on HW 70 back and forth to work.

Once in a while I go into a I don’t care mode for the month and I’ll drive with the pedal to the metal up the pass with a surprising top speed of 68 MPH twice a day (going to work and back) lol. When ever I do this I lose about 1 1/2 quart of oil between oil changes.

Now if I treat it super nice and stick to the slow lane uphill I’ll hardly lose any oil .

In the end it all depends how hard I make the engine work. I’ll do a cylinder compression test on the car one of this days to see how the engine is holding up. But over all Toyota makes awesome engines.
