Case of Toyota 5w20 motor oil for sale.

[ibanezjeepguy]

my first dealer oil change on our yaris was done with 5w30. my most recent change they put 5w20 in per service notes on my receipt. as long as they honor the 7 year warranty they can put whatever they want in it! I figure the only real benefit is gas mileage as it doesn't take the pump as much effort to push around the fluid, less resistance means it can get to the bearings faster!
