I could probably go well over a year but it just feels wrong. I will certainly agree that, with the right car and conditions of course, a year is A-OK.

I really hate it when car manufacturers stop putting dipsticks for engine oil. Beside the ability to check the oil level with my own eyes, not having a dipstick also makes it difficult to get a few drops of oil to see its condition.(with my eyes or running it between my fingers)
