Yes, High Mileage can be used with a synthetic blend. It’s safe and effective in any oil blend, conventional or synthetic. Add it about 100-300 miles before your next oil change so the Sea Foam has time to re-liquify varnish and deposits (which will be drained away with the old oil).

Hope that helps!
