I've waited to post until I had three oil analyses done. My car is an 05 Legacy GT Wagon, 5MT. Only "mods" are a Cobb AccessPort running a Stage 1 91 octane map. Oh, and the very expensive Hog-zawst.
My driving mileage is probably 80% highway and 20% city. I typically average about 24 - 26 MPG (usualy with 10% ethanol fuel, since it is hard to find non-ethanol around here). I occasionally will push the car hard but not very often.
The blue text was added by me to show what oil and oil filter was used and to clarify how many miles were on the oil.
I would appreciate some thoughts on this. I went from 4k miles on the M1 to 4.6k miles on the Rotella. Then, I was curious and extended the last interval to 7.5k!
I can't tell a single bit of difference between this interval and the last 4.6k interval with the Rotella.
It appears that the Rotella held up better than the M1 did originally. Would you agree with this?
Think I should stick with 7.5k OCIs or go back to something like 5k? I average about 2k miles per month.
Thanks all.
