Has anyone used Lucas Heavy Duty Oil Stabilizer in either diesel engine oil and/or 80/90W gear oil? If so, what was the result(s).

Mark, I have just started using their oil stabilizer in the engine in my Western Star, put a quart in my transmission too. Only been a couple thousand miles, but I have used the diesel fuel supplement for a couple years and had great results, so I figured it couldn't hurt. In the engine, I had just dropped the pan and put in main and rod bearings. In the transmission, I have a small drip around the PTO, and it seemed to slow the drip down. Only put in the quart and I think they recommended a gallon out of 5. The only drawback I see is it is expensive, but they do make great products. Oh yeah, I have been using the hub oil in my trailer wheel bearings for years. I love it.

Hello; while i am not experienced with these old cats; i have many years of messing with the wheel types. 2cyl some ihc case and plenty of molines. Virtually any gearbox of mine is 4/5 oil and 1 part Lucas; as well as the engines. Several years back i bought a Ford Fairmont with a 200 inline 6; the upper train was a little noisy; after changing oil and filter with 1 Part, i fired er up and she quitened down enough to hear the ignition a clicking. I also have noticed the gear boxes on my old tractors quitened down imm. I can open up the plate over the trannies and You will find not that much wear. I cannot promise any one they will have as good a luck as i have had; but i won't even concider an OC without it.

The reason i asked is that i was wonder if I would get good result or ''stave off'' a potential problem(s). Nearly finished restoring my 120, 14k grader and it's going to see work plowing snow soon. I'll post some nice before and after photos when I figure out how to size my pictures.
