Lucas Oil Stabalizer?
 

I need to do an oil change soon and i was wondering if any one has used Lucas oil Stabalizer on thier RX7,I just dont want anything to go wrong If anyone knows please let me know before i do anything dumb

The Lucas oil Stabilizer is a waste of money.

lucas is a thickener that will quiet down noise in the valve train...

no valve train no need..

just dont waste your money

i HAVE used it in my 85 gsl se and it improved my oil pressure alot from about 28 psi on idle to over 40 psi at idle it helps the oil seels in my opnion

Don't do it...especially if you still have the stock oil injection.
Trying to burn that stuff is just...scary.

Don't waste your money with all those oil additives.
Majority of them are snake oil.

I normally use a little bit of Marvel Mystery Oil for oil changes and when I get gas.

I can see how that would stop you from farting but how does it replace an oil change?

He didn't say it did.

ya i wouldnt mess with it because it might burn it differently. I say you get something like 20 weight oil which is thicker and perfect for our seals and u should be fine

Lucas is nothing more than bright stock, which is essentially oil base with no additives to it at all. This includes anti-foaming agents. Originally made for commercial truck transmissions, I've seen dozens of testimonials of truckers draining their tranny after overheating (which Lucas was supposed to prevent, but often makes worse for the following reason) to find the inside of their gearbox was turned into a cappuccino. Our engines don't have anything like that kind of churning in them, but I still say to steer clear.

All it does is increase viscosity a great deal, regardless of what it feels like between your fingers. It's popular with the low-budget ricer crowd, because often they wear and scuff the crap out of their cylinders. But the band-aid usually ends up wearing out the engine faster even though it can feel better in the meantime. Oil is a very complicated cocktail, and diluting the additives royally screws it up. Don't believe me? Go bake a cake with twice the recommended amount of flour and see what you end up with.

Edit: They do make one product that performs well enough: the Upper Cylinder Lubricant, since it adds lubrication where there is normally minimal. But for us, you get a better and cheaper reaction from adding ashless 2-cycle instead.

The only times I've used lucas was in my dirtbike and streetbike when I had them, but in both instances, I had tons of tiny air bubbles in the oil. No good.

For Lucas test results and pictures, just read this.

I have one of those little lucas displays, you know, the kind you find at autoparts stores with the little crank and gears showing how awesome lucas is. Crank it good for about a minute and you'll find the exact same thing, foam, and lots of it.

Oil pressure at idle is supposed to be 30psi. That's not an improvement that's a problem. Think of it as blood pressure. You want... enough.

Lucas = molasses. People with leaks, poor sealing parts bouncing around and what not will use it to slow down the problem for a while. Then the molasses causes all kinds of friction, heat, wear, restriction and pressure build up as it sticks everywhere. A better option for people with those problems (until they actually fix them), is to use 20w50. It's a little thicker, but not insanely thick like Lucas. Your car was not designed for such thick oil like Lucas, and it will eventually cause problems.

Might as well give you the rest of the info on your oil change. Use API certified 10w30 (thinner) or 20w50 (thicker). Don't use 20w50 in arctic weather (even mild snowy winter ok). Don't use fram oil filters. Never use any oil additives. Beyond that it doesn't matter much. See FAQ and/or do a forum search for more info.

Yep, I used to know a guy who studied off the shelf oils for NASA projects he said he's never seen any oil addative that didn't completly f&^k up the oil you put it in. If you want something better, get a better oil.

^^ anything?? Just curious because z-max came to mind, although I've never used it.

I just use Mobile 1 and thats it.

He said anything that you put in as a complete change was fine generally speaking, of coarse there are other things we have to consider with a rotary. Oil makers design their oils with specific needs in mind so throwing an addative in there just skrews up the "balance of the system".

I've seen an engine where Lucas was used extensively and it looked like any other engine we've torn apart.

I wondered about prolong.. I'd like to fill a rotary with 4.7 quarts of prolong and turn the oil meter system off/ run prmix.. yes no engine oil... what do ya think then??

NO.

NO.

I'm with Ted... NO

I use Elf synthetic oil... no additives and it works great!.

if you think your engine needs additives its time to work on the engine... there is no such thing as Mechanic in a Can

Thanks for preventing me from making a dissaster. So the Best thing would be to add thicker oil? Since i would like prolong the life of my seals or should i just go full synthetic? I also heard you cannot just add any full synthetic it has to be a good brand like Mobile 1, or i could end up causing problems later.

Basically wax and a few solvents. Probably the worst thing you can put in your oil and fuel besides sand...
