I have a 2012 Lexus IS350, 2GR-FSE motor, calls for 5W-30. It has 115k miles on it, and it currently has 5500 miles on the oil and filter. I filled it with Mobil 1 AFE 0W-30 and put an Amsoil Ea15k filter on the car. I'm about to take a 400 mile road trip tomorrow, should I consider changing the oil just before the trip? The motor does not seem to have burnt or leaked any oil in the last 5500 miles. I'm thinking that I should be good at least in terms of filtration. I guess the biggest concern would be whether the M1 AFE 0W-30 would hold up to an extended drain interval. I cannot find many answers about M1 0W-30 and extended drain intervals. What do you think? I do drive with an extremely heavy right foot, if that matters.
