Well you will get as many answers as there are list members, and I think that as long as you stick with a name-brand oil in the weight(s) recommended in the shop or owners manuals, you will be fine. Can't say as I have actually heard of an oil-related failure on a DeLorean due to choosing the wrong weight of oil. I am also considering recruiting some list members to help me do some oil analysis testing on the PRV. I would need people that have 100% well running engines who do mostly in town driving and they would have to use the Purflux filter. Perhaps over the course of a couple years we could test enough oil so we could come to some real conclusions. There are some variables that would be hard to control however. For instance you couldn't participate if you recently took the engine apart w/o running a rinse oil first, and you couldn't use any oil additives or anything. Hopefully each person could use whatever oil their engine has been using for at least a couple of oil changes in order to further reduce variability due to a recent oil type change. The number of different climates we all live in will take an effect too. I am starting the process this spring by running a rinse oil of Mobil 10W40 (leftovers) after I get my oil pan and exhaust back on, run that for 500 miles, then change oil and filter with Mobil Delvac Super 1300 15W40. I have a feeling the PRV will really like this oil. It is also diesel rated with a very robust additive package. I will run this for a couple of oil changes, and then sample it. I would also like to try out a 5W30 and check for oil consumption and wear metals (due perhaps to too thin of an oil?) as well as a 10W30 and a 20W50. 10W40 will probably quickly sheer down to a 10W30 so I don't know if I will even bother testing that except to see if I am right.
