I am also using Mobil 1 No.110 filters. I only put about 18 miles a day on the car, straight down the freeway and back commuting. I'm a little concerned with oil consumption though, I've used about 3/4 of a quart in 3300 miles on the Redline. I hope it settles down soon. The car was broken in according to the book. Please post your next analysis, I'll bet a lot of people are also using the Redline rather than the Ester Oil and my guess is that it will turn out to be a sound choice.
