I would not go over 5k or so, no matter what oil bottle or book says. Oil cheaper than replacing piston rings.How many of ypu do the 10k mile oil change. Seems a bit of a stretch
I did 3 times that for oil changes on my tundra 4.7 using mobil 1...no issues for nearly 300k when I sold the truck. It never touched a drop of oil, and ran strong. I even sent oil samples to Blackstone which claimed the oil was still good enough to run. Synthetics just don't go bad in 10k miles. 5k is back in the old mineral oil days when grandpa did oil changes.
I like sleeping too. LOLWhat can I say other than ...people are like sleep.
Tell me about it. I've had a MacBook Air for the last six years and I still don't know all the buttons and that auto spellcrap stuff. The only thing I learned on this keyboard is if you depress the "option" button and the "4" button at the same time it gives you the ole "¢". Just my 2¢. No pun intended.Fixed it...dam spell check feature in this iMac changes words if they have the same amount of letters in them.
