Lost mileage with synthetic blend???
So wally world had Rotella 10w30 synthetic blend on sale for the same as regular 15w40, I figure winters coming so why not. 2000 miles later and Im noticing 3/4 to 1 mpg drop in mileage. Blow by and general oil consumption also seem to be a bit higher. 208,000 miles on motor its always drank oil since I bought it at 164,000 miles, about 1 quart every 2500 miles....
Anyone else run into this when going to synthetic or synthetic blend?
