I was a regular user of Lucas oil additive at every OCI until I began reading this forum a few years ago. You fellows convinced me that oil alone really is enough to protect an engine. Now I only use Lucas in one of my old mowers whose engine both burns and leaks oil.
With that being said, I think most engines will tolerate Lucas better than some people fear here on BobIsTheOilGuy. For example, one of our neighbors has a 1996 Toyota Tacoma 4x4 with the 3.4 V6. He uses a quart of Lucas at every oil change; I mean this man believes in the stuff religiously. At this point he's at 470,000 miles on that engine with no rebuild. I see that truck regularly and know its history fairly well.
That man's son has a 2005 Toyota 4Runner with the V6 engine. He also uses a quart of Lucas at every oil change and currently has 335,000 miles on that engine.
I really don't know what to make of cases like this. Did the Lucas help with longevity in some way, or are some engines just very tolerant of thick oil?
