Hello. I have a 1992 Nissan Maxima SE VE30DE with 106k. I have some lifter noise and/or VTC tick on start up but lessens once oil gets through the passages. How much of High Mileage Sea Foam should I add as it has 5 quarts of oil? Also, does this play well with other engine treatment such as Engine Restore or should they be used separately? Is it okay to leave the Sea Foam in the engine for the duration oil life cycle interval (leave it for X months or mileage)?
