has anybody looked at Lucas oil stabilizer? I have been making many trips to auto parts storeslatly and noticed a display that has a series of gears stacked up with a crank on the top gear, when you turn the crank the oil clings better with the additive. would anybody like to comment on the usefulness of tis stuff in say...a transmission, Rearend, Engine????

i've used Lucas in other engines that were high mileage and it seemed to do what they claimed but after seeing this demo i won't use it again! thanks Dave graemlins/cheers.gif

This might be easier...... https://www.bobistheoilguy.com/images/lucas/lucas.htm

...but, is his little engine running the same RPM as our car engines? Maybe I missed that tidbit

Tony,
I think the subject was gear oil additives for rear ends. If so, the usual differential ring gear turns at around 1/4 the engine speed, ie, maybe 1500 rpm at the most. He was duplicating the store demonstration. Since the main problem with the additive was aeration of the lube, I would suspect that the problem would be worse at higher speeds.

I don't know what it would do in engines, maybe cause air entrainment, maybe not.

Keep in mind that oil "cling" is not as much of a concern in a pressure lubricated system like an engine. It is a factor, but not nearly as important as in a tranmission or rearend where "cling" and splash is all you get.

What astounded me the most is how the synthetic gear oil didn't climb at all. Synthetics for the engine under pressure is great, but is the synthetic so slippery it won't cimb making it not the best choice for the longevity of transmissions and rearends?

Oil additives do exactly what they are designed to do... take your money out of your pocket and into theirs...

Thanks for the infomation and refering me to the test website. I can now say for sure that I will not be wasting any more money on that stuff. I guess when you think about it if oil manufacturers could make a better product they would. Or like trying to modify a new car to make it more fuel efficient if the makers of the car could do it it would help them sell more cars and they would , and do put a lot of $$$ into making a better car than the other guy graemlins/cheers.gif

Good point, but keep in mind that often greater fuel efficiency can be achieved, but the increase in initial cost offsets the fuel efficiency bonus so it isn't done ... This is probably the case with some oil manufacturers also, although the testing seems to indicate that no further fiddling is required in the case of oil.
