Yes, absolutely! Sea Foam High Mileage would work great in your Lexus LS430. It’s made to clean stubborn deposits and residues from the fuel system and oil crankcase in higher-mileage vehicles.

Here’s what I’d do:

Wait until you have a low tank of fuel (1/4 to an 1/8 tank or so) and add a full can of High Mileage. Then, drive it until almost empty before refueling. That gives the High Mileage a chance to work through the system, and the high concentration will do a great job cleaning.

You can also add High Mileage to oil. Add 1 ounce of High Mileage per quart of oil in your crankcase. We recommend adding it 100-300 miles before your next oil change.
