The only differences I have noted on airplanes that are flown (not sitting for months at a time or rarely flown at all) is the consistently lower valve train wear and or less to no sticking valve problems with the semi-synthetic oils vs. the strait weight oils.

One thing I usually do is evaluate the oil consumption of the engine. If it is "good" then I would consider semi-synthetic oil. If the consumption is on the high side I usually use a "straight-weight" detergent oil. Reason? Cost. The synthetic, because of the lower viscosity, will slightly reduce fuel consumption, maybe by 1 or 2%. If the engine burns oil, why throw the extra money away? Also, if the engine doesn't run very often the oil that's thicker at ambient temp will take longer running off the cam lobes. However, I saw an ad for some synthetic that bragged about preventing that, so it would be interesting to get more comments. Incidentally, I've typically used Shell, mostly because it is easier to find, but I've talked to some that say that the Phillips oil has some advantages. There is also folklore out there that says that engine rebuilders love Shell semi-synthetic because of all the extra business they get from cam wear. I don't think I buy that.

Suggestion: After you hit "reply" to reply to a post, select the post, or better yet, and excerpt from the post and hit "control-C" to copy (like I did on the post below). Then hit "control-A" to select the entire message, followed by "delete" to erase everything. Then hit "control-V" to paste the copied excerpt back in and start typing. A huge savings in bandwidth and then I don't have to scroll down through endless repetitions to find the message. Note the number of "greater than" marks in front of the line below - that's how many times it's been repeated. Thank you everyone. > > >>>>>For the most part it's just Gary Casey
