i run valvoline racing oil 50wt in my car. so thick its like tar. thats what i think is maximum protection. nero at titan recomended it.

 

oil that heavy, make sure you never use it in temps below 90deg weather. because that is seriously thick, and the oil would not pump well in cold starts and even weather remotely not warm.

 

I remember seeing some test results with this stuff that were really bad. Foaming or something along those lines.

seems to pump through my engine just fine. then again my engine has modified oiling system.

 

synthetic with the correct wt as spec'd by toyota

Lucas.... and after you put that jizzunk in, get some sea foam, STP, and a quart of rear main seal saver and some injector cleaner. Make sure you get as much stuff in the color purple as possible. Purple stuff is the color of clean. Don't forget to add the slick 50 TEFLON. Cause dat's da good shizz.

I like to get all that stuff, put it in a jigger, shake and then put it in the tank. I call it the engine renewal cocktail.

 

Im takin it thats a no?:1poke:

I would not really mess with oil additives. Some say it is good for the seals, but the chance of that foaming scares me a little. I just stick with Royal Purple synthetic.

As for putting anything along the lines of oil additives: About every year, I just put about 2/3 can of sea foam into my crank case and run it for 10 minutes. Then I drain the oil, and noticed that it is much more black.

 

I run 1 qt lucus with the rest mobile 1 syn 10/30. Been doing it for yrs. Still on stock bottom end and many many many 34lb pulls on a gt47-80.
I guess it can't be all bad?

 

do you guys recommend sea foam? and where to put it? gas tank?

 

Interesting thread. My family has owned and operated a truck repair shop for over 30yrs. We have a dyno and have done hundreds of engine rebuilds etc.. In my experience engines running Lucas oil additive at every oil change have outlasted engines that have not. I've seen engines last well over 1million miles that have used it at every change. Even on constructionn equipment that came in for a refresh (bearings rolled etc..) at the recomended service interval that ran lucas usually the bearings came out looking almost new (pending any dirt in system or service intervals etc.)

I know I know these examples are not from a supra but they are used in heavy load applications. Needless to say I'm not surprised at how many owner operators request lucas in their rears, transmissions and engines with the price of oil these days. I run it the Lucas synthetic additive in my supra (.5qt per change) and like it over the conventional lucas we sell here since it seems to be of a slightly lighter viscosity.

 

MissSupra - Don't you have a built stroker ? If so it would depend on the clearances being run, your oiling system,etc. What did your engine builder recommend oil wise ? I personally wouldn't run Lucas Oil Additive but known people who have with no problem, just not in "Race engines".
