Maybe I’m paranoid but I’m a little worried to start the car with the oil that’s in the car. The reason is because the new seals are pretty tight on the valve stems and seem that they could prevent oil from getting down to the guides. The car currently has the recommended 10W-30 but was thinking that maybe I should change it to maybe something like 5W-30 before the first start-up - giving the seals time to loosen up and then switch back to the original oil weight after a week or so. What do you guys think?
In case it makes a difference the new seals are Fel Pro viton. Both intake and exhaust.
