I am not sure what the lucas additive is, but generally you want to have the least amount of additives mixed into your oil on higher reving engines.

yeah i use lucas and it works great.. makes idle slighty smoother and the oil pressure is way higher... the psi is at 45-50 stock at idle and 75 psi over 3000 rpm(autometer oil pressure gauge reads that)... it cant hurt your engine.. its not synthetic.. no teflon.. just natural..

I've seen it in stores, and it sounds interesting, but the promo material sounds too much like all those Slick-50 types that keep getting busted for unsubstantiated claims, so I've held off on using it...

Sounds like motor honey and it cost $10 a quart around here. It needs to be mixed 20% with engine oil. This doubles your oil change cost. It would be more beneficial to change the oil twice as often.

Notice benefits:
A. increase oil life-who cares- change every 2000 miles
B. reduce oil consumption--oil injected rotary-no comment
C. eliminates dry start--no OHC's/valvetrain/...in rotary
D. raises oil pressure-- so does improved oil pressure regulator, switching to a thicker oil, or using a high quality less restrictive filter(but where does the dash measure oil pressure--before filtration?)
E. increase power--Thats it. I got one reason to buy it!
See the viscosity(@100 C) of it compared to lucas 20/50 and 10/30. Thicker fluids are more difficult to pump resulting in more power wasted pumping. Why strain the oil pump, chain, and engine?
And if you think not, drink honey through a straw and compare to drinking water through the same straw. Wasted effort.
Using lucas's numbers:
10/30 has viscosity of 10.5
20/50 has viscosity of 21.5
Sae50--------------------20
Sae70--------------------30
oil stabilizer-------------110
20% of that added to your oil changes it properties considerably. Just use the proper weight of oil to begin with and change it frequently to prevent oil breakdown.

Lucas
While I would hesitate to recommend any additive in an otherwise good rotary engine I will take a moment to say something about the stuff.
In 1988 I purchased a Ford Bronco new. It had the 302 in it. From the outset the engine used what I considered too much oil. I found out to my dismay that Ford does not consider anything over 250 miles to a quart excessive, so I was unable to get anything done under warranty. At first the oil consumption was around 450 to 500 miles per quart. By 30,000 miles it had increased to 300 miles per quart. Of course by then the warranty was expired.
I started using Lucas in this engine as a last resort. It immediately went to over 750 miles per quart of oil consumed.
As with many Fords, I knew the valve seals were the culprit. The engine smoked for a few seconds at start up but did not smoke any other time.
If you have a POS engine Lucas might help.

lucas sponsors alot of racing teams. and i guess they use the lucas oil treatment and the various lucas oils in their cars/ trucks to get a competitive edge.
nah whenever its on speed they have offroad racing with the trucks.. thats all that i know about it.

anybody ever talked to Rotary tuners or mechanics about it? how about some of the more well known forums members that have been working on there cars for years. it seems like its still kinda up in the air here as far as yes or no. i've got a bottle of the stuff sitting in my garage from my dads last oil change on his truck and i'm thinking about adding some to the mixture in my oil change SOON so i myself am curious as to whether or not i should.

Geez, I also gave the weblinks. Anybody care to read them, the product specs sheets, or msds's. Yep, Lucas is the ****
I'll save my money for more frequent oil/filter changes. Capitalism is great. You buy the Lucas additive and make Mr. Lucas rich.Heres simple math for you:
4 quarts 10w30@10.5visc +1 quart lucas@110visc=
5 quarts blend @ 30.4visc ((4*10.5 +1*110)/5). Thats 50% thicker than 20w50. Thats scarey.
We don't need mud for oil in the rotary. We don't have piston ring blowby or valve seals to worry about. Thick oil is an easy compression adder for tired boinger engines; so is sawdust. Why don't you add that to your rotary?
It also stops smoking, leaking, knocking and blow by. Knocking caused by? Must be the famous rotary rod knock
Smoking in a rotary? Mine is oil injected. I do not want mud oil clogging my $1200 electronic MOP, oil lines, or oil injectors. If it smokes a little, I know everything is OK.
Leaking in a rotary? Replace the gaskets, lines, seals or whatever leaks. If it is still leaking, rebuild!
I have a problem with any additive that claims to "eliminate wear". That is a strong claim. Eliminate is a powerful word. Wear in an engine will never be eliminated. It will always happen.
I'll agree with copandengr "If you have a POS engine Lucas might help."
I'll agree with Amur. The promo material is bordering on deceptive/misleading. Soon, it will be added to the rest:

Feel free to use it in your engine, power steering, transmission, rearend...... And, if anything breaks, copy/paste this weblink:
