How many miles do you plan on putting on the odometer between oil changes using a synthetic vs synthetic blend?
Motorcraft blend is supposed to be one of the better ones but I don't see the point of using any blends, especially if they don't publish the ratio.I typically have been doing 10K miles between oil changes on my normal vehicles. I had planned on doing 7.5 k on the Bronco because of the turbos. But after reading the owner's manual it's clear that 5K oil changes are going to be what's needed unless you do nothing but street driving.
I'm personally still unsure about the blend oil. I can't imagine why they would want to not have full synthetic.
And it's all logged in the computer. Ignoring the warnings may lead to refused warranty claims.either way it will eventually instruct you to “change oil soon.” Which will then turn into “change oil now”.
