" From: Tom Jennings <tomj@xxxxxxx> " " " " I was running up to 10K miles but it made me nervous, for no reason " I can think of, and I've reverted back to 5000 - 6000 per change. " I should probably just go back to 10K. " " Oh, I am running only Mobil One 10w30 plus a Mobil One or NAPA " Gold filter. I did fool around with 0w30, doesn't seem to make " any difference. 1. mobil is advertising a '15000 mile' oil grade. combine this with a remote filtration setup with the 2qt filters... and you're almost doing an oil change when you replace filters anyway! 2. i've heard repeatedly of tests/reports that took oil filters apart - read one - and they all agree the ac delco is the only one worth anything, head and shoulders above all the others. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
