After a few days of driving since the oil change with Lucas and the filter change, the ticking noise is pretty much gone! I am very excited to get this outcome. I have read people's opinions on additives such as Lucas and I've seen mixed reviews. I even read about a test conducted at "Bob knows oil.com" suggesting that Lucas may not be as good for the vehicle as advertised but I have also seen many members of that forum saying how wonderful it is.
I have had my own experience with Lucas on a previous vehicle (97 Tacoma) and I sold the truck (after 9 years of usage) with 162k miles and no problems...
