nschroed Posted October 26, 2006 Share Posted October 26, 2006 I have several friends who swear by this stuff. I have a 97 ls 400 with 105000 miles on it. Does anyone have any opinions on this stuff. thanks Quote Link to comment Share on other sites More sharing options...
romy Posted October 26, 2006 Share Posted October 26, 2006 Every manual I have read on any car says "Do not add any additives". Quote Link to comment Share on other sites More sharing options...
nc211 Posted October 26, 2006 Share Posted October 26, 2006 I haven't a clue about the Lucas stuff...but you'll never see it in my car, that's for sure. If you want to change your oil, then change it to full synthetic, if you're not using it now. If you really want to clean up the oil in the engine, do a search for the Seafoam thread. Blake and I have both done this, and it has helped tremendously to keep the oil nice and clean. I checked my oil yesterday, it has 4,700 pretty hard miles on it...and it still looks good. Not good enough to not change my oil, but looks better after 2 treatments at 4,700 miles than my oil use to look before the treatments at 2,500 miles, that's for damn sure.

dole2000 Posted October 27, 2006 Share Posted October 27, 2006 I used to use it on my landcrusier. Great stuff. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted October 27, 2006 Share Posted October 27, 2006 It is pretty much useless for a modern car with tight clearances. It basically is an oil thickener and can cause foam. Moved to the general maintenance section. Quote Link to comment Share on other sites More sharing options...
