I changed my minivan's oil in January, temps were dropping fairly cool. I decided to try Quaker State's Winter Oil as it was on sale at our local Crappy Tire stores. I have to say that the van does start easier and runs nicer when cold with this oil, I was using Castrol 5w30 oil in the last OCI. But I really like the way the QS Winter oil is working this winter. I believe it's advertised as a semi-synthetic blend, I wonder if they are using more synthetic oil than other typical blends to give it added benefits in winter temps. Is there anything else they could do with the oil to make it work better in cold temps which conventional oils don't get ?. I kinda thought it was marketing hype but it seems to be working very smoothly with less engine noise at all times. Oil consumption is also zero so far to date, and the oil appears cleaner on the dipstick as compared to the Castrol.
