Adding Sea Foam High Mileage to oil – 1992 Nissan Maxima SE VE30DE [SOLVED]

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)?

Hi Isael. For treating your 5-quart oil crankcase, add 5 ounces to half a can per interval. Though we recommend adding 100 to 300 miles before each oil change, you can add for as long as the full life of the oil if you wish. You’re good-to-go either way!
