Have had the 98 LS400 for the 2nd day and last night went to fill it up at the gas station and after I fill the tank to the top with regular the wife points out the “premium fuel only” sticker on the gas door. Will the car be ok for the tank full or will something bad happen to it. Does anyone else run strictly regular grade? The owners manual says it’s ok until you can get back to premium!

Welcome to the AF!

If the owner's manual says it's ok for a tankful, then I wouldn't be concerned. Just don't drive it really hard until you get premium in the tank.

If you're worried about it, put in an octane booster from an auto parts store for this tankful.
