So I downloaded the owners manual (just Google it), and it says to use only 0w20 in the 2.4L, and 5w20 if you have the 3.2L. But, the user guide I downloaded says 5w20 for both. :huh:
A 0W-20 and a 5W-20 are the same VISCOSITY when the oil is at the operating temperature. A 20 GRADE oil is measured at 100c so both the )W-20 and the 5W-20 are measured at t.hat temperature. The 0W and the 5W are measured at different temperatures. The 0W is measured at -40c and the 5W is measured at -35c. It is true that the 0W-20 would be a better choice if operating in very cold temperatures, but it would also give better lubrication on start-up, as it would flow better. A high quality synthetic would even be better for start-up, as well as lubrication properties.:smile:I think I would go with the owners manual. I though I had read somewhere that 0w20 was for cold weather operations and 5w20 was for warmer weather.
I did RP on my first oil change and it cost about $50 for 6qts. My second change RP was up closer to $60, even at Walmart, so I did Pennzoil Platinum for about $30. I've looked up many NOA/UOAs and don't see anything that justifies RP for that kind of cost.
can't go wrong with that
