I was using 5w30 and found with the mileage(which are close to yours the oil wasn't doing as good so I switched to 10w30 and haven't had a issue or lost a quart of oil due to use but the brand and type is up to you me I prefer castrol over Mobil 1 but that's me

I switched to 10W-30 as soon as I bought my ESV. I live in a tropical climate where we seldom see temps below 50* F so I have no need for the lighter weight oil.
