So it's been a few weeks since I had the oil changed in my car from 5w30 to 10w30. The technician in the oil change shop recommended I try to see if it helped cut down on the amount of oil that burnt up between oil changes. While I don't know if it has helped because I haven't hit the 5000 km mark to change the oil again it did notice a few performance issues.
What I noticed first was that the car was harder to start on cold days because the cold temp viscosity is higher so it is more viscous than the 5w30. This was a bit of a concern because it was a little more rough on the engine after it first started to run but it smooths out quickly.
So far this is the only difference that I have noticed and to alleviate the issue I have been making sure that I ALWAYS plug my car in on cold nights. As long as I plug it in it starts just fine. I suspect that this starting issue will be even less in the spring and summer because the temperatures aren't as low so it should start easier. I think what I'll do in the future is run 5w30 in the winter time so it starts easier and run 10w30 in the spring, summer and fall. I will post again on this subject after I have had the next oil change.
