... I understand from several tests posted here that it lacks anti-foam additives and can contribute to foaming and lube problems on high speed engines....
To me that huge lack of quality and performance questions the whole product line.

I used it with regular gear oil in a 100,xxx mile 4spd tranny to quiet it down and it worked great. Plus it slowed any leaks you would expect from a 38 yr old tranny that hadn't ever been rebuilt.  I think I would use it on a 75,xxx mile plus engine but not a newer engine.

Moparless for now but when the opportunity is right I'll have another one.

I saw an analysis of the Lucas oil stabilizer that said it was almost 100 percent petroleum base stock, no additives in any significant amount. In other words a waste of money.

Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.

I am not going to say anything for or against the Lucas oil additive. I will just state the following facts. You make up your own mind. I worked for a company that has the second largest private fleet of Class 8 trucks in the country, second only to Walmart. Manufacturers are always using our fleet as a test bed. Standard Operating Procedure when changing the oil on each tractor is to send the oil out to a lab for analysis. After 1 year analyzing the oil when Lucas was used, the company made Lucas standard as part of the Preventive Maintenance Program. I had a car with a SBC LS-3 engine. After adding Lucas, the normal operating temperature dropped 5°. That is all....

There was a thread a couple weeks ago in the Race section about Lucas additive in a dyno pull on a new motor. They made a couple pulls and the oil pressure started bouncing around. They pulled the plug and foam drained out of the pan. They replaced it with straight Brad Penn oil and the foaming went away. Use good oil to start with and leave the additives for the suckers with too much money.

Lucas is pour oil thickner. Like adding 40wt gear oil. No extreme pressure lubricant or acid reducing properties.

Motor oils are a blend. They all have additives like the zinc they took out of the Motor oil. And all in different proportions.

I've used it on an old tired SB Ford that was oil fouling plugs. I was amazed, it cleaned the plugs up nice. I've also seen the tests where it foams up. In the end, I think I would use it as a last resort for an engine that has little left to lose. On a good engine I would just use a good quality oil.
Hey Bob.....
Hows the 440 running since you cured the oil smoke problem? I remember that you had the intake off and that you replaced the valley pan and gaskets. Hope that everythings running tip top.

Hi, thanks for asking. I only drove it 100 miles or so after I fixed it but it went well...then had to park it because winter crept in. I've been putting in a new interior for the last month or so. Hoping to have it done within the next few weeks  Hopefully the snow will be over by the end of March and I can get it back on the road again.
