Hi all, I purchased a Subaru Legacy last year and with the purchase I received lifetime oil changes from the dealership. I thought that was great, but I normally don't wait till 7500 miles to change oil, even if it is synthetic. Usually I change oil at the 5k mark or 6 mos. But after the first 2 changes, they are now pretty stubborn about changing oil before 7500 miles, unless I reach the time allotment to the next recommended change. I don't have far to commute so I haven't reached the 7500 miles on a single oil change yet (3 oil changes, 13,000 miles) but it's MN, so the weather can be extreme, like this last winter. My question is, is Subaru oil really up to the task of 7500 miles on an oil change? Or is this going to destroy my engine following "the recommended manufacture guide" on oil longevity? If not...I figured I'd just start doing my own oil changes at the 3750 mile mark, in between the freebies, even though that is probably to soon. Thanks in advance!
