All highway miles. I don't know the age of the air filter but I cleaned it during the last oil change with a air gun from the shop
This report is from October and I currently have 3815 miles on the oil in my car. I was thinking of changing the oil now and getting another report to see if the silicon levels went down. Then if all looks good, I'll run the fresh oil for 5000 miles.
What do you guys think?
Also this was the first time synthetic oil was run in this car.
bkbenjy,
Is your 2.5 oil as black as mine is? My 04 Altima 2.5 oil starts to get black after a week of my OCI. Been like this since new. Use the same oil as I do in my wifes Lexus. Always use popular oils(dino/syns) held in high reguard here at BITOG. Her oil look clean at 3000 miles. By 3000 miles my 2.5S is really BLAAAAACK! Almost coal in color. No make up oil. Doesn't leak/burn. Runs great! Both vehicles 6mo/3000mi
