Back story on my truck: I went in to the dealer at 76,000 miles and at 89,000 and had the reprogram done on the cam phasers, and the noise came back with a vengeance at a 102k. Buy 107,000 it was a loud rattle on every start up with as is little as 15 minutes in between. It no longer need a coldstart to rattle. It was very loud and had grown from 1 second to lasting 3 seconds before it would go away.
Well I thought I would try an oil additive before I had to pay for the repair out of pocket.
I worked! It doesn’t rattle at all between stops and it has a very slight rattle after 12 hours of sitting. Maybe a 1/2 second. I only used one bottle and it calls for 1 qt for every 4 qt of oil needed. So I could still add 1/2 a quart if I drain some old oil first. My truck seems to use 7/8 of a quart of oil every 5000-6000 miles and I was almost a quart low when I added the Lucas on Tuesday. I was due an oil change, so I thought what the heck I’ll give this stuff a try before I go with a heavier weight oil.
Thought I would share this (new to me) information.
