Here is the latest UOA from my 2007 manual 5 speed corolla. Pretty good mix of city stop and go driving and 70mph highway trips. This last OCI was the second run of purolator white can oil filter, so it was on the car for 11,000 miles. Replaced this with PP 5w30 and a supertech oil filter. Records show a solid average of 38mpg over this last OCI. I live on the KS/MO border and have been trying to buy my gas in KS and it seems to help my mpg average. MO gas is mandated to have ethanol, KS isn't. I will gladly pay the ten cent difference.
