Hey Scotty Im almost due for my next oil change.. Owners manual states 0w20/5w30/10w30 oil which one is the best? Im currently using 0w20 is it ok in hot climates 35-40 degrees C weather?
95°F-104°F is relatively hot. Dan's on it like white on rice. 10W-30. Heat lowers the viscosity of most fluids (e.g., motor oil), so you want to go w/ the highest recommended Summer weight, which is the "30" number. TIP: Look on the back of bottles of 5W-30 and 10W-30. L@@K at their operating Temperature range charts. You'll see they overlap by a bit and can rest assured you're picking the right grade.
