Reply to "What Oil to run in the Pantera?"

The best oil to use is typically the same oil you have been using. Problems arise from changing oils (unless it's a new engine). The worst thing you can do is go from a non detergent to a detergent oil. It will break up particles that were built up (originally un-disturbed). Some times peopel will use one type for break in then switch to another to run through out the engine life which is ok. Basically, pick one and stick with it.

Experts have quoted the pure synthetics as the ultimate if you can afford them. Many an aircraft engine has been bought by synthetic oil companies after they tore them up. They do well but cannot absorb everything the petrolium based oild can. When they get saturated they start gumming up stuff. Many aircraft and car manufacturers will not longer warrent their engines if you use PURE synthetic oils. If you do, change it OFTEN (which is in oposition of what they say). The minute it gets dirty, you'll start getting deposits on things such as pistons, etc.

I am no expert here, just repeating what I have been reading in aircraft journals.
