I find this one. It may help you.
"First, check for and correct any oil leaks around valve covers and oil pan. Tightening bolts may do the trick. If not, install new gaskets or have the work done. (This procedure won't stop leaks.) If front or rear engine-bearing seals leak, add a can of "Bearing Seal Additive" after Step #2. Chances are it will stop or vastly minimize the problem at low cost. (It did for me.) Okay, here are the 3 Steps:-
1. Drain engine oil and replace oil filter. You've probably been using a multi-grade 10-30 or 10-40 weight oil. Or a straight 30 weight oil. Regardless, replace that oil with one grade heavier, single-weight of oil. During warm months, use 40 weight; in the winter (depending on how far the mercury dips in your part of the country) use 20 or 30 weight. Slightly thicker oil won't hurt that worn engine, and if your battery is good, it'll turn over fast.
2. Add two cans (30 ounces) of Alemite CD 2 for Oil Burning, which replaces one quart of the oil you would normally use during an oil change. (If capacity with new filter is less than 5 quarts, use one can of the Alemite.)
3. Drive vehicle at town-speed, 20 to 35 miles per hour, for at least 50 miles (a 100 mile distance is better), before opening it up to expressway speeds. That's all there is to it!
Steps #1 and #3 are the real secret, assuring success when the "usual" additive treatment helps little if at all. Here's why, as my mechanic friend explained it to me:-
The Alemite contains a substance that builds-up between ring and cylinder wall, forming a tough, long-lasting seal. Problem is, standard 30 weight (in moderate clime) and multi-grade oils are too thin; they don't have sufficient "body" to prevent most of the sealer from blowing past rings BEFORE it can do its job. A heavier, single weight oil retards the blow-by and speeds-up the seal formation.
Driving at moderate speed for the first 50 miles or so, also helps accomplish fast seal build-up. Use a heavy foot on the accelerator immediately after treatment, and the fast-moving pistons pump much of the oil and sealer out the tail pipe.
The sealing compound, after setting-up, isn't as hard as steel. So, to prevent seal from deteriorating, add one can of the Alemite when changing oil thereafter. You might get away with going back to a thinner or multi-grade oil. But, why bother changing a winning combination"
