<div class="ygrp-content">Does this still hold for older engines that have some sludge build-up in them?

In my humble opinion.

I noticed an article on the opening page of the CJ3B website about ?which oil should I use?. There is a link to an article that applies to our jeeps. <font color="#1e66ae">http://www.newengla<wbr>ndclassics.<wbr>org/Articles/<wbr>The%20Evolution%<wbr>20of%20Engine%<wbr>20Oil.pdf</font>
A similar article was in HotRod magazine last month. In summary they are both recommending diesel truck oils in engines with flat tappets. There are anti scuff additives in the diesel oil which has been legislated out of passenger car oils (in 2004). I also hear that the diesel oils have to be cleaned up in ?06 so that advantage will go away. Given the low speeds and lower stresses of the jeep engines compared with a ?60?s high compression V8 has anyone seen data on how the jeep engines are doing with the lesser oils? I cant help thinking that todays car oils are still superior to anything that was available 40-60 years ago.
Anyone had a tappet or cam failure?
Tom

<div class="ygrp-content">Good point Paul. We should not suddenly switch oil in an old engine from
straight mineral oil to a semi-synthetic detergent becuase the particles
that become loose and drift through the oil system have a tendency to
plug up small passages. Switching from straight weight detergents (Which
are semi-synthetic) to multi weights (which are semi synthetic) is not a
problem.
